Get with the Program & Get More Out of Amateur Radio Club Meetings

19 July 2024 at 13:26

We’ve been fortunate to have a hard-working program chair in charge of arranging our club presentations. Even when he’s wintering in Florida, he makes sure everything is ready for the next meeting and joins in via Zoom.

It’s not just about filling a time slot for the monthly meeting. Without good programs, no club can succeed or survive for very long. The program chair’s most challenging job is providing programs that will appeal to club members—not put them to sleep.

Sometimes clubs take member surveys to get ideas, seek club officer input, or ask members during casual conversations what programs they’d like to see. Unfortunately, the answer is often “I don’t know” or “Something about ham radio.” So program planners must constantly think of new ideas and strive to make every program interesting and timely.

Ideas

You don’t need to reinvent the wheel. There are many potential speakers out there, including ones who have already done programs for other radio clubs. They may have a list of topics they’ll do or may even have some videos of previous presentations you can download and show to your group.

Club Members: Your group may have some individuals who have some expertise in specific ham radio topics that could be turned into an interesting presentation. Elmers are a logical choice—people who are good at explaining technical topics so they are easily understood.

Being a good storyteller also helps. One of our members did a presentation about electromagnetic pulses (EMP) and their effect on radio equipment. But he also wove in a story about our area and the Cold War.

Hamfests: Hamfests are a great place to learn more about the hobby through forums, presentations, and vendors. Many of these presentations have been recorded as PowerPoints or videos and are available online or by request.

Vendors will sometimes have presentations available or be willing to speak live to your club via video conferencing. This is a win-win situation. Your club gets a program and the vendor gets to introduce products and how they work. Our club recently had a presentation from a California-based company that sells products that suppress RFI/EMI and noise, as well as a line of baluns and antennas. We got some tips on dealing with RFI and some questions answered as well.

Ready-to-Go: Ready-made PowerPoints and videos? They’re available. See the list of links at the end of the article.

High-Profile Hams: If you’re lucky, you may be able to schedule a well-known ham to do a program. A number of years ago, our ARES group had the opportunity to hook up with H. Ward Silver, N0AX, for a video conference. John Portune, W6NBC, is one of our favorite Zoom speakers when it comes to building antennas, along with Al Christman, K3LC, who lives locally.

Contest stations K3LR and W3LPL have online video tours where you can see their well-equipped contest stations. You can also see their extensive antenna farms, complete with some bird’s-eye drone views.

Borrowed Ideas

During my travels, I’ve visited several radio clubs and seen some great presentations. An interesting one I saw in Arizona was about the pico balloon, an ultra-lightweight plastic balloon suspending a tiny, lightweight amateur radio transmitter. They’re capable of sailing around the globe—sometimes many times. Unlike other balloons, they use hydrogen because it leaks less than helium.

Be sure to get the presenter’s contact information and ask if they’d be willing to do a presentation for your club—most likely it will be done by Zoom.

Project Sessions

These don’t always have to be on a regular meeting night. Schedule them when it works best for your group—maybe a Saturday. If you choose to make it the meeting activity, keep it simple and doable within a reasonable amount of time. Things like making coax jumpers, 2-meter J-pole antennas, or a simple choke/1:1 balun can be completed during the meeting time. Individuals can be responsible for materials or the club can make a group order. (Suggestion—get the money upfront for group orders.)

A variation of this would be the show-and-tell. Members bring in projects they have completed and share with the group. They can answer questions about parts needed, how it works, and building tips.

Courtesies: Always be a class act.

Here are some things you should remember:

Before:

  • Invite the speaker at least two months in advance of the meeting.
  • Give the date, place, theme, and any other information pertinent to the meeting.
  • Specify the amount of time allotted and whether a question-and-answer session will be expected.

After Accepting:

  • When the speaker accepts, acknowledge the acceptance promptly. Provide further information about the meeting and location and agree on the presentation time.
  • Inform the speaker immediately if there is any change in the scheduled meeting time and place.
  • Send a reminder e-mail or phone call before the meeting date.

During the Meeting:

  • Start the meeting on time. The presenter’s schedule comes first—don’t make them wait for your business meeting to end.
  • Introduce the speaker with a brief bio.
  • Members who insist on chattering or being a distraction should take the conversation outside.

After the Meeting:

  • Write a thank-you to the speaker within 48 hours of the meeting. Comments complimenting the speaker on specific points in the speech are always appropriate.

When You Need to Punt

Poet Robert Burns once said, “The best laid plans of mice and men often go awry.” No one can prevent the unexpected. Everything from illness to snowstorms, floods, and technical difficulties can prevent your speaker from showing up for your program. You can plan for such emergencies by setting up a reserve of programs in case a speaker cancels—or your Zoom connection fails.

So You Got Your Ham License? Here’s How to Start Enjoying Amateur Radio. (Video)

18 July 2024 at 13:30

It’s a sad truth: Many people in the ham radio community never explore the opportunities afforded to them by their Technician license. You pored over the ham radio study guide, learned the basic math, asked your Elmer a million questions, and passed the test with flying colors.

But that’s as far as things progressed. It’s a common story: Life gets in the way.

While there are many reasons why new hams don’t make use of their first license, one of them isn’t a lack of opportunity to have a blast on the air. A Tech license opens up a vista of privileges, some of which are the coolest and most valuable among the long list of ham radio activities.

In today’s OnAllBands video, Michael Murphy, KI8R, DX Engineering customer/technical support specialist, shows some of the ways you can take advantage of punching your amateur radio ticket, along with encouraging words and practical advice on making your operating goals a reality.

But the question, “I just got my license. What’s next?” doesn’t just apply to new operators, as KI8R explains. Moving up the ham radio licensing ladder to General and Amateur Extra brings new opportunities but also may elicit more questions about how you may want to move into other areas of interest.

Enjoy the video below. And if you’re new to the hobby, welcome aboard! We can’t wait to hear you on the air!

Doing a Good Turn: Choosing the Right Rotator for Your Amateur Radio Station

17 July 2024 at 12:53

A rotator is a handy device used in ham radio communication systems to change the orientation of an antenna. Rotators have two parts, the rotator unit and the controller. The controller is normally placed near the radio equipment, while the rotator is mounted on the antenna mast below the antenna. It’s a must-have for DXers and operators who want to extend their reach and improve reception.

Is it Rotator or Rotor?

Let’s settle this before we move on. Hams tend to use both words interchangeably, but there is a subtle difference.

  • A rotator is a device, such as a motor, that makes something rotate—like a mast with a Yagi attached.
  • A rotor is a part of a device that rotates, such as a brake rotor or armature.

How Does an Antenna Rotator Work?

The rotator is typically mounted on the antenna mast or inside the tower, directly below the antenna, while the controller is usually placed in the ham shack near the operator’s position. The controller sends signals to the rotator unit, instructing it to rotate to a chosen heading.

Modern rotators are generally small. Due to gear reduction, the motor mechanism can be relatively compact and not draw much current. Large rotators have bigger motors, but the increase in strength is mostly due to improved gear and brake systems. The power required to turn even those big, stacked arrays is not that much.

To keep rotators from twisting in the wind, they include a braking mechanism. Smaller ones use a friction disc arrangement—when the rotator turns, the discs move apart to let the mast turn freely. When power is removed, the discs clamp together again. With medium-sized rotators, brakes consist of a heavy-duty solenoid with a spring-loaded wedge or bar that fits into indentations inside the rotating housing. On big rotators, worm gears are used and braking is done by the resistance to the gears turning backward under load.

Rotators are designed to turn a full 360 degrees, and often a bit more. That is known as overlap. At the ends of rotation, mechanical limit switches open to remove power from the motor. It’s important to leave a rotator loop in your feedline during installation to prevent stretching or breaking your feedline.

Choosing the Best Antenna Rotator

Durability is important, especially for something that’s exposed to the elements. Look for sturdy materials which can endure outdoor conditions without corroding or deteriorating over time. Opt for models with a sealed housing to protect internal components from moisture and dust for long-term reliability and performance.

Make sure the rotator you choose is compatible with your specific setup. This includes assessing antenna size, weight, and mounting considerations. There’s nothing more annoying than finding that your rotator won’t fit properly inside your tower. Also verify compatibility with any existing hardware you plan to use, such as controllers, accessories, and mountings.

It’s important not to overload a rotator. If you live in a location that’s subject to high winds, continuous winds, or large gusts, look at the wind load recommendations included with the unit. These are usually specified as a maximum antenna area in square feet or square meters. Add all of their wind load numbers together for several antennas on a single mast, and don’t forget the mast’s wind load. You can find your antenna’s specs in the manual or online.

A rotator can handle a larger wind load when mounted inside a tower section, as opposed to mast mounting, since the tower holds the mast in place straight above the rotator. Using a thrust bearing keeps most of the load off the mast, further increasing wind load capabilities. Inside tower mounting eliminates any sideways load on the rotating assembly relative to the base.

antenna rotator instructions
Mounting the rotator on a pole or mast limits the antenna’s size and the mast’s length from the rotator to antenna. This is due to the significant bending forces applied to the rotator’s clamps. Mount the antenna as close to the rotator as practical in this configuration. (Image/DX Engineering)

In the preferred tower-mounting configuration, a sleeve bearing provides additional support. Another option is using a thrust bearing at the top, which transfers the weight of the antenna and mast onto the tower and off the rotator. The rotator then just turns the antenna without the extra load.

Controlling the Rotator

Each manufacturer of rotator/controller combinations has its own design of control boxes for controlling the rotator and displaying antenna position. Yaesu’s desktop controllers provide a round dial with a 360-degree radial indication of antenna azimuth bearing. Hy-Gain HAM-IV and CD-45II models include a more traditional analog meter readout with N/S/E/W markings and azimuth readings in five degree increments.

There are also aftermarket control units that operate with many different rotators. These include the Green Heron RT-21 Series Digital Controllers and the EA4TX ARS-USB Rotator Controller with digital readout. The coolest of the group is the microHAM ARCO Advanced Rotator Controller (below) with touchscreen LCD control and azimuth information superimposed on a world map display.

(Image/DX Engineering)

If you’re old school, you may want to control your rotator manually with the clockwise/counterclockwise buttons or do point-and-shoot using the preset dial. If you plug in the call sign of a station, most logging programs will provide you with the short path and long path settings you’ll need.

Newer rotator controllers may have an interface—either RS-232 or USB. Some controllers can be connected directly to your PC to operate your unit. Older controllers may require an additional interface board that can be installed inside the rotator control box. For example, programs like PstRotator and DX-Lab can directly calculate the beam direction for long and short path and pass it on to the rotator control. Many of the popular logging software programs can also control a rotator with the help of a PC. The Ham Radio Deluxe Software suite for Windows includes the HRD Rotator Control module, which manages beam headings via any computer-interfaced rotator controller.

Interested in space? An antenna rotator with both rotational and elevation controls, like the Yaesu G-5500DC (plus related software), is essential for ham radio satellite, ISS, and EME (moonbounce) communication. It enables users to accurately track satellites and the ISS as they move across the sky. Such equipment can make adjustments quickly, maintaining a solid connection for communication.

What’s Right for You?

Decide what antenna(s) you plan to put on your mast or tower and calculate the total wind load. It doesn’t hurt to go a bit larger on your rotator. You’ll have some additional headroom and prepare for the possibility of an antenna upgrade or added antenna later on. It’s difficult to change out rotators on a tower—I know from experience.

Rotator packages usually include the necessary connectors. You’ll need to supply the wiring between the controller and the rotator, usually a six- or eight-conductor for ham rotators and three- or four-conductor for TV/light-duty rotators. They can be purchased by the foot or as ready-made cables. Other items to consider include thrust bearings and rotator shelves inside tower mounts, like the DX Engineering Accessory Shelf below for Yaesu and Hy-Gain rotators.

New Product Spotlight: DX Engineering Logo UltrAtomic® Wall Clock

16 July 2024 at 13:18

The DX Engineering Logo UltrAtomic® Wall Clock features dramatically improved reception and reliability, allowing you to automatically set and keep time, even at daylight saving time changes.

DX Engineering Logo UltrAtomic Wall Clock
(Image/DX Engineering)

Excellent readability and attractive styling make this DX Engineering 14-inch analog clock a great addition to any amateur radio station, office complex, school, or home.

The UltrAtomic receives the enhanced phase modulated WWVB broadcast signal introduced by the National Institute of Standards and Technology (NIST) in 2012. This advanced technology allows the radio time signal to “break through” barriers like cement walls, unlike previous PWM-only atomic clocks.

WWVB is a time signal radio station near Fort Collins, Colorado. It is co-located with WWV, a time signal station established in 1919 that broadcasts in both voice and time code on different shortwave frequencies. You can read a brief history of ham radio and WWV, WWVH, and WWVB in this OnAllbands article by Mark, K8MSH.

A Clock Loaded with Features

This is the DX Engineering version of the La Crosse Technology wall clock that was the first on the market to be based on this enhanced broadcast. The UltrAtomic clock operates even in the harshest conditions, such as when the signal-to-noise ratio interferes with radio-controlled clock reception using the legacy AM signal broadcast.

UltrAtomic technology digitally processes the received signal via an integrated circuit within the clock. It leverages the advanced modulation scheme and new data encoding. The reception reliability of the technology has been validated in the most challenging locations and scenarios and has been demonstrated successfully throughout North America.

The clock lets you select any time zone with a custom setting, especially UTC/GMT. Now you can enjoy UltrAtomic accuracy while viewing any time zone around the world.

The phase modulated WWVB broadcast includes a notification for daylight saving time transitions well ahead of when they occur. The clock reads and stores this information and, at the appropriate instance, automatically advances the hands one hour in the spring and eleven hours in the fall (to move back one hour), even if the signal is not received on the day of the transition.

Other features include:

  • UltrAtomic time with manual set option
  • Barrier-resistant signal reception with dual antenna that is insensitive to orientation
  • Adjustable time and zone (24-hour World Time)
  • Eco Mode extends battery life—turns second hand off from 11 pm to 5 am
  • Q-Mode (Quartz Mode) for manual time setting
  • Stainless steel frame bezel
  • Glass lens
  • Black metal hands and black numerals on white background
  • Low-battery detection indicator
  • Powered by two or four high-quality “C” LR14 batteries (not included) for up to three years or six years in Eco Mode

Ham Radio 101: The Basics of Sun and Signal—A Few Useful Resources

15 July 2024 at 12:54

As a service to new hams, we’ve compiled a few resources to give you a better basic understanding of the sun and the role it plays in enabling you to fill your logbooks.

The ElectronicsNotes website provides a good explanation in the article “The Sun: Its Structure & Impact on Radio Propagation.” It notes that in terms of radio communication, the sun “is the source of radiation that gives rise to the ionosphere” and is “of great importance for HF ionospheric radio propagation.”

The article explains that solar radiation travels to the Earth, causing the upper portions of the atmosphere to become ionized. The absorption of the radiation provides protection from harmful elements of this radiation while also forming the ionosphere. The ionosphere refracts radio signals, particularly in the MF and HF portions of the radio spectrum, making global radio communications possible. As the levels of radiation change throughout a day, so do different regions in the ionosphere change.

We recommend reading this ARRL article from the ARRL Lab Staff. Mike Gruber, WA1SVF, assisted by Dean Straw, N6BV, answer some questions about how the sun influences the propagation of radio signals. The article provides explanations of the 11-year sunspot cycle, solar flares, coronal holes, A-Index and K-Index numbers, and much more.

Also, check out K7RA Solar Updates from the ARRL website under “Latest News.”

Ham Radio 101: Understanding Repeater Speak

12 July 2024 at 14:18

New hams often wonder what they’ll do or say over the radio after they get their license. All that jargon that hams use can seem like a foreign language to those who’ve had little exposure to amateur radio. But there is no need to be self-conscious. After reading this, you’ll become fluent in repeater speak in no time.

Common Amateur Radio Repeater Terms

Chances are your first QSO (communication) will happen on a local VHF or UHF repeater using a handheld transceiver (HT). Repeaters have their own terminology, like courtesy beep, DTMF, and split. However, this split doesn’t involve bananas and courtesy beeps shouldn’t be confused with roger beeps used by CBers. You’ve probably used DTMF before, but in a different context—on your phone.

Here are some repeater terms you may encounter while you’re on the radio.

A Glossary of Ham Radio Repeater Terms

***

  • Break: A word used to interrupt a conversation on a repeater to indicate there’s an emergency. You should say “break, break, break” to be sure you’re heard. It’s not used to join a conversation.
  • Deviation: This refers to the change in the carrier frequency of an FM transmitter produced by the modulating signal. If you’re told your transceiver is over-deviating, talk farther away from the microphone to avoid distortion.
  • Double: Two or more stations transmitting simultaneously on the same frequency, often without knowing it. The one with the strongest signal wins, but if it’s a tie, neither is heard.
  • Full Quieting: This term usually signifies a good quality signal on a repeater or FM transmission. It means that your signal is clear, free of static, and easily readable.
  • Half-Duplex: Radio communication using two frequencies, one for receive and one for transmit—one radio at a time.
  • Hang Time: This is a cure for the double. Waiting briefly between transmissions allows smooth transitions. It also gives others a chance to join in the conversation.
  • Kerchunking: You have an HT, but will it reach the local repeater? Turning it on, you briefly hit the transmit button and hear a tone in response. Satisfied, you try it again—and again. That’s kerchunking—keying up a repeater just because you can. It can really become annoying to anyone monitoring the frequency. The proper way is to say your call sign when you transmit, or something like “KE8XYZ, testing.” I even heard of one repeater that reportedly responds with “kerchunk” if it is keyed and no audio is detected.
  • Machine: This refers to the repeater system itself. You might hear something like, “The 37/97 machine has the best coverage in the county.”
  • Offset/Split: If the repeater output is 146.840 MHz, the input or the frequency the repeater receiver listens on is 146.240 MHz (600 kHz below 146.840 MHz). The offset prevents transmit and receive signals interfering with each other at the repeater.
    • If you’re tuned to 146.840 MHz, when you push the mic button your radio automatically transmits on 146.240 MHz, 600 kHz down from 146.840. When you release the mic button, your radio switches back to 146.840 MHz to listen on the repeater’s output frequency. Confused? No worries—virtually all ham radios sold today set the offset automatically.
  • Open Repeater: A repeater that may be used by any licensed ham radio operator is considered open. Closed repeaters are restricted to exclusive groups, such as members of a club.
  • PL Tone: PL (private line) tones or CTCSS (continuous tone-coded squelch system) tones are sub-audible tones of 300 Hz and below that are transmitted and detected by radios and repeaters. The tone is transmitted when you talk, and the repeater lets you through if you’re using the correct tone. It’s used to prevent people accidentally keying up on a repeater frequency or a repeater interfering with another repeater during a band opening.
  • Repeater Directory: It’s a publication that lists repeaters in the U.S., Canada, and other areas. A popular repeater directory is published annually by the ARRL (below). You can also find directories on the Internet from many sources. Do a repeater directory search to locate them.
  • Simplex: This is communication where hams receive and transmit on the same frequency without using the repeater. It’s also called talk around. You can do this to avoid tying up the repeater, especially if you’re not far apart.
  • Time Out: No, you don’t have to sit in the corner. This happens when a person talks too long and the repeater time-out timer (TOT) temporarily shuts down the transmitter. There will be a short pause, then the repeater will reset and the conversation continues.

Try the DX Engineering N8DXE Repeater!

If you’re ever near Akron, Ohio, you can access the DX Engineering Amateur Radio Club (N8DXE) repeater at 146.985 MHz. It was recently upgraded to the Icom ID-RP2010V repeater, which allows for both digital and analog operation. D-STAR gateway access is unchanged. For analog, there is no PL to access the repeater. However, the repeater will transmit a 110.9 Hz tone so you can set up your analog radio for Tone Squelch. This will allow you to filter out the digital traffic. Of course, if you are in digital mode, it already filters out the analog traffic.

New Product Spotlight: DX Engineering High CMI Receive Feedline Choke

11 July 2024 at 13:59

Premiered at Dayton Hamvention® 2024, the DX Engineering High CMI (Common Mode Impedance) Receive Feedline Choke (DXE-RXFC-75) achieves exceptionally high isolation between the input and output connector shields to effectively block common-mode RF noise and unwanted signals that collect on 75-ohm receive antenna feedlines. The choke—the result of ongoing work by DX Engineering’s research and development team—makes an ideal choice for typical and advanced low-band receive antenna systems.

Before we get into the nuts and wires of the DXE-RXFC-75, you may be asking, “What exactly is a common-mode current and why is it harmful?

For our answer, we turn to Ward Silver, N0AX, who explains it in his OnAllBands article, “Baluns and Common-Mode Impedance: How Much is Enough?”

“In this article, common-mode current, or CMC, means current flowing on the outside of a coaxial cable shield. Because of the skin effect, the inside and outside surfaces of the shield can carry different currents. Fields from current on the outside (the common-mode current) are not canceled by fields from an opposing current as they are for the shield and center conductor currents inside the coax. This means common-mode current will radiate like any current on a wire, and external fields picked up by the shield from the transmitted signal or from other signals or noise will create common-mode current on the shield.”

Ward Silver, N0AX

So why block CMC? As the article above notes, blocking CMC reduces re-radiation that distorts the radiation pattern and reduces re-radiation near equipment that can cause RFI.

About the DXE-RXFC-75 High CMI Receive Feedline Choke

Covering 100 kHz through 30 MHz, the DXE-RXFC-75 Receive Feedline Choke exhibits very high common mode impedance (see specs below), typically over 7,500 ohms across the 160, 80, and 40 meter bands. It features DC pass capability up to 700 mA at 13.8VDC, with extremely low SWR and negligible insertion loss.

The DXE-RXFC-75 has a nominal impedance of 75 ohms with Type-F connectors to prevent accidental connection to transmitting equipment. The choke is built into a two-inch square plastic box, 1.5 inches deep, with non-directional input and output F connectors on opposite sides. It’s permanently sealed to prevent changes to the precisely adjusted components by physical shock or internal moisture. The top and bottom sides each have 7/16-inch flanges with 3/16-inch holes for mounting (hardware not included).

DXE-RXFC-75 High CMI Receive Feedline Choke Specs

Nominal Common Mode Impedance by Frequency (Approximate)

  • 100 kHz – 1,250 ohms
  • 200 kHz – 2,500 ohms
  • 1.8 MHz – 8,000 ohms
  • 3.8 MHz – 10,000 ohms
  • 8.0 MHz – 8,000 ohms
  • 21.0 MHz – 4,500 ohms
  • 30.0 MHz – 2,500 ohms

Insertion Loss

  • 0.1 dB at 1.8 MHz
  • 0.2 dB at 7 MHz
  • 0.4 dB at 30 MHz

VSWR: <1.25:1 maximum; 1.06:1 at 7 MHz, nominal

Some Things to Consider About the DXE-RXFC-75

  • Receive feedline chokes do not reduce ambient or propagated RF noise that is received by the antenna, nor do they reduce RF noise in a receiver that is conducted by a power main or noise that originates inside a power supply.
  • Low-noise receive antennas are traditionally located away from electrical wiring and other noise sources for improved signal-to-noise performance. However, local and propagated RF noise and other unwanted long, medium, and shortwave signals can energize the outside of the feedline shield. Installing a DX Engineering High CMI Receive Feedline Choke blocks the direct path for that RF noise to the feedpoint of a low-noise antenna, through the feedline shield connections between the station equipment and the receive antenna system.
  • This choke should be placed at the antenna end of the feedline, at the receive array phasing unit, or remote switch end of the coaxial cable, or at both ends of very long receive antenna coax cable runs. Installed in line with the receive antenna feedline, it’s a passive device which requires no power and does require a direct ground connection. It should be installed on the long coaxial cable side of any ground connection.
  • Receive feedline chokes cannot be used on the output of a transceiver. Transmitted RF energy will cause permanent damage to the DXE-RXFC-75.

Backup Power for Home & Field

10 July 2024 at 13:42

Power. It is one of the most important aspects of running an operation. But what if you don’t have access to AC power or a storm knocks out all power in your area?  

What Are Your Backup Power Options?

There are some differences if you are at home or in the field. At home you will want to power more than just a radio and its accessories—things like a refrigerator, air conditioning, and internet service.

What you want is an uninterruptable power supply (UPS). These can be as little or as large as you can afford. Most of us have small units connected to our computers for safe shutdown. There are room size UPS units that back up large data centers, hospitals, and other critical infrastructure.

The big question is how much runtime do you get? This is almost solely dependent on…

…you guessed it. Batteries.

Lead-acid batteries, most often deep-cycle, are a good choice for emergency power. They are rugged and have relatively low energy density. The deep-cycle option also handles a slow discharge well. They can be used with or without a battery box. A battery box can be purchased or homemade. The cost is on the lower side for batteries as well. The main disadvantage is that they can be extremely heavy, which is usually not an issue for home use.

The next option for home use is a generator, like the Generac GP3600 Series Portable Generator shown below. These can provide power for an extended time period and are rugged. However, generators are bulky and not easy to move. You also need to have fuel to power them and keep them running smoothly.

Solar is a good choice for home and portable use. It also has the advantage of being environmentally friendly. A solar cell, or photovoltaic cell (PV), is a device that converts light into electric current using the photovoltaic effect. Multiple solar cells are connected inside modules and modules are wired together to form arrays. The arrays are then tied to an inverter, which produces power at the desired voltage.

A large array for maximum power can become very expensive. Home solar systems often have a way to store excess energy and feed it back into the power grid. Portable solar panels come in many shapes and sizes that you can roll up, fold up, or fold over for easy storage. Straight panels that are more rigid are a good option as well.

You’ll find several solar power options at DXEngineering.com, including Bioenno Power foldable solar panels and solar charge controllers, and the Samlex Solar Portable and Foldable Solar Battery Charging Kit below.

So, what are some good options for people out on a field exercise or during a Parks on the Air activation?

A choice that is growing in popularity is a power station, like the A-iPower 300W Lithium Portable Power Station below. It includes outlets for USB and 12-volt power, with receptacle plugs for easy hookup and power supply. While power stations are relatively lightweight, they may not be the best option for tossing into a backpack from a weight perspective.

Another extremely popular option is the lithium iron phosphate battery. Lithium iron phosphate (LFP) is an inorganic compound with the formula LiFePO4. Some of its advantages include long cycle lifetimes, high power density, wide operating temperature range, and easy transportability due to its light weight. You can find a range of Bioenno Power LiFePO4 12VDC batteries (see the 12 Ah model below) and battery/charger combos at DXEngineering.com.

Product Spotlight: DX Engineering 400MAX Type-N to PL-259 Low-Loss 50-Ohm Coaxial Adapter Cable Assemblies

9 July 2024 at 13:32

Plus New Cable Gripper for RG-400 Size Coax

Wouldn’t it be great if all connectors were uniform, and you didn’t have to worry about A fitting into B, and B fitting into C? As any ham knows, variety is the spice of building and maintaining an amateur radio station. It’s just one of the aspects of the hobby that makes being an operator endlessly interesting and challenging.

While DX Engineering enjoys the challenges, we also relish the opportunity to make life a bit simpler for our fellow hams by coming up with solutions to common problems, which is the subject of this blog entry.

Problem: What if two devices, say, your transceiver, switch, meter, lightning protector, or antenna, have opposite female connectors—one type-N and the other SO-239?

Solution: DX Engineering 400MAX Type-N to PL-259 Low-Loss 50-Ohm Coaxial Adapter Cable Assemblies

Available in lengths up to 300 feet (3, 6, 50, and 100 feet assemblies are in stock, other lengths are custom-made by special order), these assemblies make an excellent choice over less-reliable straight adapters. The cable assemblies are:

  • Made for any job (HF, VHF, and UHF)
  • Terminated with one top-quality silver-plated Type-N male connector and one patented Next Generation PL-259 (UHF male) connector
  • Wrapped in a waterproof jacket made with UV-resistant, Type III-A polyethylene, which is ideal for all outdoor feedline applications, including direct-bury installations
  • Suited for short or long cable runs and low- or high-power level operations; cables feature a large 10 AWG stranded copper center conductor
  • Enhanced by modern, gas-injected foam polyethylene dielectric that cannot absorb moisture and has complete shielding
  • Made for high performance and excellent longevity
  • Continuity and Hi-Pot tested and then heat-shrink weather-sealed

Both connectors feature machine-crimped shields with 360 degrees of complete mechanical and electrical contact for maximum reliability. PL-259 center pins are hand-soldered, and Type-N center pins are machine-crimped by trained assembly techs to assure a proper connection.

Further, Next Generation PL-259 connectors feature:

  • Full-diameter, full-length soldered center pins that snugly fit even worn SO-239s
  • Spacious center pin inside diameter that accepts large conductors and allows generous solder flow
  • Deep, double-knurled threaded shells for secure finger tightening
  • Silver-plated brass shells and bodies with center pins securely mounted in PTFE dielectric for exceptional RF characteristics and power handling

Even More Options for Purchasing Coaxial Cable

You can also order the specific length of 400MAX coaxial cable—and a variety of other cables with the connectors you desire—by selecting the specific length (up to 300 feet) and connector types at DX Engineering’s Custom Cable Builder at DXEngineering.com. DX Engineering cable can also be purchased in bulk spools of 500 and 1,000 feet or by the foot.

New DX Engineering Coaxial Cable Gripper

DX Engineering is pleased to introduce a new hinged coaxial cable gripper (DXE-CGH-195) to add to its impressive lineup of coax prep tools designed to firmly hold coaxial cable while you prepare it for connector installation.

The device provides a dramatically improved grip on DXE-8U, DXE-400MAX, DXE-11U, DXE-213U, standard RG-8 or other RG-8U size (0.405-inch nominal) coaxial cables.

It’s All in the Cards! QSL Cards from Jarvis and Palmyra Islands

8 July 2024 at 14:20

Jarvis Island QRV in August 2024

The Rig in a Box (RIB) N5J DXpedition to uninhabited and infrequently visited Jarvis Island (a dual DXCC entity with Palmyra Island) is only about a month away. If Jarvis/Palmyra is one of the few remaining locations standing in the way of your goal of “working the world,” N5J—scheduled to run from August 5-17, 2024—presents an excellent opportunity to check off this ultra-rare entity from your list.

Jarvis/Palmyra ranks as #18 globally and #9 in Europe on Clublog’s Most Wanted List. For up-to-date details about Jarvis Island N5J, visit their official website.

The N5J at-island (local) operating team of Don Greenbaum, N1DG; Mike Snow, KN4EEI; Tomi Pekarik, HA7RY; Rig in a Box innovator George Wallner, AA7JV; and Adrian Ciuperca, KO8SCA will be joined by remote CW and FT8 teams from around the world who will be active via Starlink. Chasers will be able to reach operators on 160-6M in SSB, CW, and FT8.

N5J members have been working with U.S. Fish and Wildlife Service (USFWS) officials for several years to obtain permission to operate from the Jarvis Island National Wildlife Refuge. The Rig in a Box concept, which allows hams to operate remotely through self-contained stations (radio, antenna, and power) set up on land, helped to make this activation possible. The local team will be conducting the DXpedition from the MV Magnet, a vessel that will be just offshore of Jarvis Island.

About Jarvis Island

Located in the South Pacific Ocean halfway between Hawaii and the Cook Islands, 1.7-square-mile Jarvis Island is an unincorporated, unorganized territory of the United States. It is administered by the USFWS as part of the National Wildlife Refuge system. Jarvis was declared part of this system in 1974. In 2009, President George W. Bush designated Jarvis Island as part of the Pacific Remote Islands Marine National Monument.

OnAllBands Geography Question of the Day

Jarvis Island is one of a handful of U.S. territories that have the distinction of being both “unincorporated” (not fully incorporated under the U.S. Constitution) and “unorganized” (directly administered by the federal government). Several rare DXCC entities are included among this list (e.g., Baker Island/Howland Island, Johnston Atoll, Wake Island, Midway Islands, and Navassa Island).

Can you name the only unincorporated, unorganized U.S. territory that is populated? Answer below. Can’t wait? Find the entity in question in this OnAllBands article.

DX Engineering Gear to be Employed on Jarvis Island

In DX Engineering’s ongoing mission to stand beside hams who are putting rare DXCC entities on the air, the company contributed a range of gear to complement the RIB setups:

QSL Cards from Jarvis and Palmyra Islands

The avid DXers at DX Engineering have made several contacts with operators on Jarvis and Palmyra islands over the years. Here are a few of their QSL cards, from the oldest to the latest.

Wayne, K8FF, DX Engineering customer/technical support specialist, worked the K1AZA/KP6 Palmyra Island DXpedition in May 1962 when his callsign was K8WOT.

Scotty, KG9Z, DX Engineering customer/technical support specialist, provided us with QSL cards from Palmyra W0RLX/KH5 1988 and Jarvis Island AH3C/KH5J 1990—the last time Jarvis was activated. The ten-day AH3C/KH5J operation, which employed Butternut Vertical Antennas (acquired by DX Engineering 25 years later) netted 55,000 QSOs. Among the operating team was Martti Laine, OH2BH, one of the most accomplished amateurs of all time. AH3C/KH5J marked only the second time that Jarvis Island had been put on the air.

The 1988 W0RLX/KH5 activation was the first to Palmyra since the ill-fated 1980 K6LPL/KH5 DXpedition, which began with a crash landing in a Palmyra airfield, severely injuring one team member who was medevacked off the island. The DXpedition was later aborted due to another operator injury.

Tom, KB8UUZ, DX Engineering technical writer, received the QSL card below for contacting the DX Engineering-supported K5P January 2016 DXpedition to Palmyra Atoll. Read this fascinating article by K5P operator Hal, W8HC, about some of Palmyra’s history and the team’s DXpedition that recorded more than 75,000 QSOs.

DX Engineering provided the K5P operation with a range of equipment, including RG-8X Coaxial Cable Assemblies and its Ultra-Grip 2 Crimp Connector Cable Prep Kit.

I’ll take “Unorganized and Unincorporated” for $1,000, Ken.

So, were you able to name the only populated U.S. territory that is both unorganized and unincorporated? If you said “American Samoa” (population 44,600), give yourself a pat on the back! While American Samoa is self-governing, it is technically considered “unorganized” because the U.S. Congress has not passed an Organic Act for the territory that specifies how it is to be governed. American Samoa is one of two U.S. territories south of the Equator. The other? Today’s featured entity, Jarvis Island.

Editor’s Note: Every month, DX Engineering features QSL cards from our team members’ personal collections. To highlight upcoming DXpeditions, we’ll be displaying a few of our favorite cards along with details about what it took to make these contacts. We’re excited to share some of the special cards pulled from the thousands we’ve received over the years. We look forward to seeing your cards as well!

Getting Started with BOTA, Beaches on the Air

3 July 2024 at 13:57

If you thought Parks on the Air (POTA) was the only portable operation event in town, meet BOTA.

Beaches on the Air promotes ham radio portable operation from beaches. BOTA has awards for activators (those who operate at the beaches) and chasers (those who contact them). Radio amateurs can participate from any beach, country, or region around the world. The program brings together thousands of hams from six continents, and new ones are joining every day.

beaches on the air BOTO logo
(Image/Beaches on the Air – BOTA)

BOTA now lists more than 30,000 beaches and they’re constantly adding new beaches as they become active. You may activate the same beach as many times as you like, gaining additional points each time. There are no restrictions on how you travel to the activation location or the power source you use for your station. BOTA invites you to submit your beach activation images and videos.

Besides promoting fun amateur radio practices, the program offers other benefits as well. It encourages participants to get out of their shacks, do mild exercise, increase their vitamin D levels, and work on their tans. It’s also relaxing to sit on the beach and sip your favorite beverage. Kick back, chill, and leisurely log those contacts. Don’t forget to tell everyone what a wonderful time you’re having during your QSOs.

Beach Operation

Conditions at the beach are quite different from POTA, IOTA, SOTA, and other ‘OTA activations. Be aware of tide schedules, high winds, and changes in weather. Locate yourself where you won’t have to constantly move away from an incoming high tide.

You’ll likely be inclined to bring more things: beach chairs, umbrellas, coolers, and other items. After all, it’s also a trip to the beach. Be realistic about what you can comfortably carry—sometimes it’s a long walk.

Five-gallon utility buckets are great for carrying coax, antenna parts, tools, and other supplies. After you’ve emptied it, the bucket can be flipped over and used as a stand for the radio. A pack seat will also fit in the bucket and give you a place to sit or set up additional equipment. Tote bags or backpacks will help keep your radios protected.

Securing your antenna properly is important. Most operators prefer a lightweight telescoping pole at the beach, like those from DX Commander or SOTAbeams, to hold a 1/4 wave of wire. These poles have a minimal wind load and those <31 feet will generally not need guys. To make them freestanding, you’ll need a sand spike—a tube for holding fishing rods or beach umbrella holder that screws into the sand. Be sure the bottom of the pole will fit inside before you invest in one.

The beach’s biggest draw for hams is the “saltwater amplifier,” nature’s reflector for your signals. Forget burying a batch of radials in the sand because you only need one. Run it toward the water at the edge of the waves or tie a fishing weight to the end and give it a toss into the waves. Add a quarter-wave wire vertical and you’re good to go. Using the saltwater ocean as counterpoise can give you up to a 10 dB gain. A 10W QRP signal becomes a 100W signal with a very simple antenna system—really awesome!

Getting Started with BOTA

Interested? First, create an account at BeachesontheAir.com. While you’re waiting for your registration to be processed, search for activators listed on the website. Listen to a few QSOs, then call when they’re on the air. The activating station will provide you with a code during the exchange.

After you receive the code over the air from the activator, sign into the BOTA site. Under the user menu, select “Add chaser report redeem code.” Enter the code. If you have just made the QSO, click yes and add the frequency and mode so a spot is placed on the BOTA home page.

You can also keep a log and enter it all later. You have one month to enter the code. If for some reason you have forgotten the code, you can enter the activator’s call sign and then choose the activation site. Activators and chasers are not required to submit logs.

When you’re ready, plan to become an activator. You’ll go to the BOTA website and choose “Announce activation, Generate code.” Search for your beach and complete the information required. Once saved, the Admin will review the beach. If there are no issues, it will be added to the system.

There’s also a Beaches on the Air Facebook group where you can find additional information.

BOTA Operation Procedures

Here’s a basic summary of the definitions, rules, and procedures:

Beach Activation Boundary: Defined as the area between the water and the road that runs parallel to the beach. This usually includes beach car parks and may include grassed areas, paths, etc. Keep in mind the program is “Beaches on the Air,” not “Across the road from a beach on the air.”

  • Setup Location: Activators can set up a portable station or activate from a vehicle. Activators should abide by local laws regarding the setup of a portable station and obey any directives given by local authorities regarding station setup. Activators need to be aware of other beach users around them and always make sure that their setup is safe for themselves and others.
  • Operating Frequencies and Modes: Any amateur radio frequency can be used and all modes are permitted where the activation code can be clearly transmitted. Repeater contacts don’t count.
  • Multi-Person Activations: When two or more stations are activating from the same beach at the same time, all activators need to individually set up their information on the system and use their individual activation code over the air with their chasers. Each activator should take their own photo of the activation site and later upload it. There is no club/team scoring.
  • Repeat Activations: It is possible to activate two or more different beaches on the same day using different codes, but you must physically move your entire setup from one activation to the other. There’s a minimum one-hour break between the end of an activation and the start of a different one on a different beach.

Guide to July 2024 Ham Radio Contests: Islands Edition

2 July 2024 at 13:32

Okay, so Field Day is over. Hamvention 2024 is in the books. Contest Season is months away. The rare Glorioso Islands DXpedition is done. What’s a ham to do? The short answer is plenty! The long answer is, “If you can’t find a reason to get on the air, you’re not trying!”

Contesting doesn’t cool off during July, especially if you’re into operating in the great outdoors or prefer the challenge of chasing portable stations from the comforts of your air-conditioned shack (hey, you already toughed it out on Field Day, so you deserve a break). July offers one of the premier portable operating activities—the RSGB IOTA Contest: July 27, 1200Z to July 28, 1200Z.

Whether you’re a chaser or activator, the Radio Society of Great Britain’s Islands on the Air Contest is a welcome chance to celebrate the world’s well-known and lesser-traveled island groups (more than 1,200 of them) dotting the planet. The contest is based on the RSGB IOTA awards program, established in 1964 to promote amateur radio and draw attention to the “widespread mystique surrounding islands.”

If you’re new to the RSGB IOTA Contest, which has been around since 1993, click here to read a guide for novices who wish to operate from an official IOTA spot or those who seek to make contact with IOTA stations. Bands for the 24-hour contest are 80, 40, 20, 15, and 10M on CW and phone. Also for new island operators, check out this article by blogger Sean Kutzko, KX9X, “Your First Pileup, Techniques for Success.”

US Islands Award

Summer is an excellent time to hold a mini-DXpedition by activating one of America’s multitude of islands that are part of the US Islands (USI) Awards Program. Celebrating its 30th year, the program has given hams across the country the chance to activate and chase a range of river, lake, and ocean shore islands, from the ones everyone knows (Manhattan, Maui, Key West) to spots perhaps only familiar to the peripatetic amateur operator (Tonganoxie, Shuler Bend, Little Scovell).

Here’s the coolest part. Participation doesn’t require a cost-prohibitive trip to Alaska’s Kiska Island. We’ll wager that there’s an island only a few hours away begging to be put on the air. Case in point, here are a few awards-qualified islands (followed by their program number) that are not far from DX Engineering headquarters in landlocked Tallmadge, Ohio:

  • South Bass (OH007L)
  • North Bass (OH006L)
  • Kelley’s Island (OH001L)
  • Turtle Island (OH038L)

As part of the US Islands Award program, OnAllBands blogger Sean, KX9X, activated Outer Island in the Thimble Islands group off Connecticut in the Long Island Sound. He netted nearly 150 contacts using five watts and a simple multiband dipole in a few hours of operating. (Image/Sean, KX9X)

The program lets DXers vie for honors such as the USI Basic Honor Roll (QSOs with 100 qualified islands); Work All State Islands Award; and Work Ten Award (10 islands from one state). Find the complete list of more than 3,400 U.S. Islands here along with participation rules.

And be sure to check out DXEngineering.com, where you’ll find everything you need to activate an IOTA, POTA, or SOTA site, or increase your chances of reaching the many islands, summits, beaches, and lighthouses of the world. Not sure where to start? For activators, we recommend a complete DX Engineering POTA package that includes an Icom or Yaesu transceiver; Bioenno Power lithium-ion battery and solar panel; coaxial cable assemblies; antenna tuner; and more. Choose from four packages:

New Product Spotlight: Chameleon Universal Remote Antenna Tuner

1 July 2024 at 13:13

The addition of a new product from the innovators at Chameleon Antenna is always reason for celebration—perfect timing since the Fourth of July is only a few days away. Want to add some QSO fireworks to your logbook? Looking for a reliable, weatherproofed outdoor antenna tuner for your permanent installations?

Covering 1.8 to 54 MHz, the Universal Remote Outdoor Antenna Tuner (CHA-URT1) works with most antenna types and transceivers. The tuner can be used with wire-fed antennas including verticals, random wires, and long wires, as well as with coaxial-fed antennas like inverted-Vs and dipoles. The tuner can match any antenna with an impedance of five to 1,500 ohms within seconds. Tuning time is five seconds for full tune and 0.1 seconds for memory tune.

The package comes with a compact coupler (5.04″ x 4.13″ x 1.69″) and tuner (8.78″ x 5.12″ x 1.77″).

The rugged, weatherproof tuner contains the antenna matching network and controller and is designed to be permanently installed outdoors at or near the antenna feedpoint to avoid loss due to high SWR on the feedline. The coupler contains the operator controls and status indicators. It uses a bias-T circuit to send power and control signals to the remote tuner over the connecting coaxial cable, so there is no need to order or install a separate transceiver-specific control cable. The coupler is not weatherproof and must be installed inside near the operator and transceiver. Also included is 12V hardwire power cable, brackets, and hardware.

Power Handling:

  • 125W SSB phone/CW
  • 100W SSB phone/CW – 50 MHz
  • 60W all other modes

DX Engineering Lends Support to Upcoming DXpedition to St. Paul Island

27 June 2024 at 13:51

With permission from the Canadian Department of Fisheries and Oceans, the 10-operator CY9C DXpedition team is scheduled to put St. Paul on the air August 26 to September 5 from the windswept and treeless Northeast Island site, just off the coast of Nova Scotia.

The team of experienced hams, many of whom participated in the highly successful CY0S Sable Island DXpedition in March 2023, plan to be active on 160-6M, employing Yagis on 20-6M and elevated sloping dipoles and verticals on the low bands. There should be a good mix of modes available for filling bands (CW, SSB, RTTY, FT8, EME, Satellites), with an emphasis on Morse code contacts. Uninhabited and rarely visited St. Paul Island is approximately three miles long and a mile wide.

The island features an automated solar-powered lighthouse built in 1962—the third lighthouse which has served watercrafts between the Gulf of St. Lawrence and the Cabot Strait. Lighthouse chasers will be hoping to add this to their conquests (STP-002), as well as POTA (CA-0122) and IOTA (NA-094) enthusiasts.

The island is encircled by foreboding rock-faced cliffs, which will require the CY9C team to use two helicopters to transport gear and team members to the operating site.

Two operators from that DXpedition, Jay, K4ZLE, and Murray, WA4DAN, are also scheduled to operate in this latest venture. For CY9C 2024, DX Engineering has provided the following equipment for a Beverage antenna system:

DX Engineering Beverage Antenna System: This single-wire, single-direction beverage feed system (100 kHz to 30 MHz) designed by W8JI is immune to the strong signal overload and core saturation common in multi-transmitter environments, making it ideal for low-band DXers. It employs an isolated-winding matching-transformer system to significantly increase the signal-to-noise ratio in Beverage and other high-impedance antennas.

Ham Radio 101: Do I Really Need an Amplifier?

26 June 2024 at 14:15

Everyone wants to improve their signal quality, work more DX stations, make more QSOs, and earn higher contest scores.

Should you buy an amplifier or beef up your antenna system?

Both are good ideas, but is amping up worth the additional investment?

What’s in Your Ham Station?

For starters, let’s assume that you have a typical shack. Your 100W transceiver connects to a coax-fed dipole (or several) through a built-in or external antenna tuner. Thanks to the tuner, your rig can put out full power regardless of actual antenna/feedline SWR on the various bands you work. You use the same basic setup as most of your ham friends and the guys in the local radio clubs. 

If everyone has been using this setup, it must be good, right?  Maybe, maybe not. You tune in some stations calling CQ, but for some reason they don’t always answer your reply. Maybe it’s band conditions, or a stronger station is overpowering your signal. Shouldn’t it be easier than this?

You pause for a moment and dream about adding an Acom 1000 HF+6 Meter Linear Amplifier to your station (see below). Certainly, 1kW will help you kick butt in a DX pileup and let you cut though all the noise and interference. Flip the switch, tune, and be heard!

Then reality sets in and you go back to making calls with your 100W radio.

Although you may not know it, you can likely get more signal for a lot less money. Rather than shelling out thousands for an amp up front, I’d suggest you try a three-step approach to getting your signal heard. Utilizing all three will get you the best results in the long run, but you may find improving your antenna system is enough.

***

A 3-Step Approach for Improving Your Ham Radio Signal

***

Step 1: Skill vs. Brute Force

Anyone can fire up a monster amplifier and generate a loud signal—and many do. It doesn’t take a whole lot of skill to muscle your way through a pileup with a legal-limit amp and snag that rare station.

But you can also practice your operating skills, which won’t cost you a thing.

Skill has tangled with brute force for a long time. Take the Marvel Universe, for instance. The Hulk relies on brute force, fueled by anger. His strength continues to increase until he’s strong enough to take out his enemy. In contrast, Captain America has skills like marksmanship and martial arts, and is an expert tactician and field commander.

Point is, although Captain America is an enhanced soldier, those skills are really his superpower—so develop your operator superpowers and make yourself heard!

One strategy I learned is to transmit on a frequency slightly above the main pileup or the last station worked. The DX station will often explore the upper edge of a pileup if he can’t pick out calls from the main section of the pile.

Another is to delay for a second or so sending your call so the last letter or two extend past the main buzz of the pileup. In my case, the station would then hear the “SH” and send “SH?” Then I send my call again and make the QSO. Timing is everything.

Also, CW and digital modes will give you significantly more mileage than SSB. Generally, they work well at power levels of 100W or less, but you should use 30W or less for digital to keep from damaging your finals.

Step 2: Budget-Friendly Renovations

Consider updating your antenna system as the next step to improving your signal. One way to improve your signal is to move antennas higher in the air. Build a taller mast, find a taller tree, or put up a tower.

If that dipole just isn’t cutting it, try a new secret weapon—a full-wave horizontal loop set as high as possible. Feed it with coax and use a tuner on bands above the fundamental frequency. That’s a quick and relatively easy way to snag an extra 2 to 10 dB, depending on frequency. 

Changing the feedline can mean more dBs. Disconnect the coax feedline from your dipole and replace it with 450-ohm ladder line. By using low-loss 450-ohm line you’ll likely experience a 6 to 20 dB increase.

If coax feed is your only option, upgrade to a lower-loss coax. For example, you’ll gain 0.7 dB by switching from RG-8X to 400Max and 1.3 dB by replacing RG-58 with RG-8X–based on 100 feet @30MHz. Minimize the number of connectors, switches, and adapters in your feedline system to prevent additional loss.

For less than the price of an entry-level amplifier, you can buy a Cushcraft A3S tri-band beam antenna and a medium-duty rotator. This pair, mounted reasonably high above ground, will offer a 5 to 7 dB steerable improvement to your signal. By rotating a directional antenna, you can often achieve a twofer—boosting the signal you’re trying to receive while attenuating unwanted signals.

On SSB, activate your rig’s speech processor with the proper settings. There’s another 3 dB (or more) improvement, this time in the modulation department—no purchase necessary.

Step 3: Power Trip

If you can hear people but they can’t hear you, it may be time to consider an amplifier. Most amateur radio operators find that when they use a reasonable antenna system, 500 to 800W of amplifier output is usually enough power. These midrange amplifiers also use readily available 120 VAC, so there’s no need to add a 240VAC line to your shack.

An amplifier that produces 750 to 800W of output power will have a 9 dB gain advantage over the 100W signal, which is about 1 1/2 S units. If you go from 750 to 1,500W, you will have a 3 dB advantage, which is only one half of an S unit. So why go to 1,500W? If you are in a DX pileup, that 3 dB may be enough for you to be heard over the other stations. 

If you operate on the lower bands—160 or 80m—there’s an added reason to get yourself an amp. Manmade and atmospheric noise can make communicating a challenge. The primary problem is thunderstorm activity. It creates radio noise that is reflected off the ionosphere just like regular radio signals. I’ve participated in nets on both 160 and 80m and recommend using an amp capable of 1 kW or more for reliable communications.

Wait…There’s More

Buying a new amp has a domino effect. You’ll need a beefier antenna tuner and wattmeter to handle the increased power, not to mention upgrading your antenna system to accommodate the extra power. A 240VAC line is mandatory for larger amps running at full power. Materials and an electrician to install them will likely run several hundred dollars more.

Keep in mind that once you have the power, you’ll want more—not less. You’ll also note that even a basic 500 to 800W amplifier will set you back $1,500 or more. Buy the best you can afford and use it responsibly. 

Here are some amplifier candidates to consider at DXEngineering.com, including the FlexRadio Power Genius XL below.

To Buy or Not to Buy a Ham Radio Amplifier

After looking at the facts, how much improvement does your station need? As always, the choice is yours. Amplifiers are the final option, especially after you’ve honed your skills and tweaked your antenna farm. Add a 10 dB amplifier to a 7 dB beam antenna and you’ve got a 17 dB improvement in signal strength.

When conditions are poor, an amp can make the difference between being heard and being lost in the noise.

What Does the Customer Say? Hustler BTV Series Vertical Antenna Add-On Kits: Part 1, 17M Add-On Kit

25 June 2024 at 15:31

As we’ve said many times at OnAllBands, if you want the real scoop on a ham radio product, ask someone who has used the device to make QSOs during a heated contest, fight through a pileup while chasing a rare station, operate from a temporary setup in the middle of a park, or get on the air through their local repeater.

Listening to honest opinions from folks who have spent their hard-earned money on equipment is a smart step in making sure you’re buying products that will deliver as advertised. You’ll find many opinions online and at DXEngineering.com, where customers rate their purchases from one to five and often include a detailed explanation of how they use the product, their advice on installation and operation, and the results they received.

Sometimes the reviewer will offer informed criticism or make a suggestion for an upgrade—something the team at DX Engineering takes very seriously when assessing our own branded products to make them easier to use and more efficient. In short, your thoughts on what you buy from us matter. Today, we’ll be looking at reviews of the BTV-AOKC-17M DX Engineering 17M Add-On Kit for Hustler 4/5/6-BTV Vertical Antennas

Five Stars: “This is a very simple add-on kit made of high-quality materials with excellent assembly and install instructions. After installation on my 4-BTV, no tuning was needed for 17m. I was satisfied with the 1.3:1 SWR across the band. Also, the add-on did not alter any other bands as far as SWR or performance. I have the antenna on a DX Engineering OMNI-TILT so install was simple. As far as cost, price is in the mind of the buyer; yeah, DIY will be cheaper, but the convenience and quality of this kit makes it worth it in my mind. Now with the 30m and 17m add-on, I have a very low visual impact installation that performs way better than I thought it could on every band.”

Stephen, DX Engineering Customer

***

Five Stars: “Assembled and installed on my Hustler 6-BTV in less than two hours. Used the initial settings derived by the 12m kit, and out of the box I had a 1.5:1 and lower SWR across the band. This install actually dropped my already good SWR across most of the bands on my antenna. After the install I proceeded to establish a QSO with a DXpedition in Uganda in FT8 with 35 watts. Fantastic!”

Mark, DX Engineering Customer

It’s All in the Cards! QSL Cards from Crete

24 June 2024 at 15:12

Crete QRV in June 2024

The 6M/4M SV9 DXpedition by DK5EW was scheduled to end June 20. Were you able to put the mountainous Greek island of Crete in your logbook by making some magic on 6 meters? We hope so.

About the size of Puerto Rico at 3,260 square miles, Crete ranked as the 274th Most Wanted DXCC Entity per Clublog as of June, 2024.

While not exactly a rare entity, this popular tourist locale is certainly one of the most thrilling, featuring archaeological sites, a Venetian castle, stunning islands, and Europe’s largest natural palm forest. It’s no wonder that DXpeditioners find it a welcome spot to set up shop and reach out to the world.

Today we’ll be looking at a few of the QSL cards the active hams at DX Engineering have earned over the years from both permanent and temporary operations on Crete.

Crete’s QSO Machine

Crete is home to Michael Dimitrikakis, SV9CVY, who is widely recognized as the island’s most active ham. Appropriately nicknamed “The Big Gun of Crete,” he commands four impressive antenna towers covering 160 to 2M from his QTH near Rethymno (population of around 39,000). SV9CVY is one of approximately 200 to 3oo amateur radio licensees on the island.

Dave, K8DV, DX Engineering customer/technical support specialist, reached SV9CVY in March 2007 on 20M SSB and in February 2018 on 160M FT8.
