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

The CHA-URT1 features 16,000 memories for quick recall and tuning with previously used settings. Once the tuner is tuned, the relay’s latch and power is turned off, saving on battery drain. The tuned frequency will be stored in memory.

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

Let’s start with this link to a detailed eham.net review by WB0KWJ of the 17 meter add-on kit, which notes that the kit is “easy to assemble, works well, and is worth the price.”

Rather than homebrewing an add-on that may or may not work, the review says you’ll save a lot of time (the reviewer was able to use the kit within an hour of opening the box) with a “tested, effective design made of weather-resistant materials.”

17M Add-On Kit Reviews from DXEngineering.com:

Five Stars: “Easy to add to my 4-BTV. Has a flat SWR without tweaking and did not affect SWR on the other bands. Worked seven countries with 100 watts in the first week, so I’m happy.”

David, DX Engineering Customer

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

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 274^th 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.

Tom, KB8UUZ, DX Engineering technical writer, received the card below from SV9CVY. As a paraplegic, SV9CVY raises awareness by including this important message on his QSL cards: “Help the Handi-Hams Near You. They need your support.”

As noted on his QRZ.com page, SV9CVY graduated from the City University of New York in 1988 with a degree in electrical engineering, worked in New York and New Jersey for a few years, and moved to Greece in 1993. He received his amateur radio license the following year. Here he is featured on the cover of the April 2018 issue of QST magazine.

He wrote on QRZ.com,“The very best part of this hobby is the PEOPLE you meet and the longtime close friendships that happen as a result of the common interest in Amateur Radio.”

About the Recon 40

This high-performance HF antenna coil is capable of tuning 40-10 meters when paired with the REZ-Z17 17-foot telescoping whip (not included).

Made with 14GA enameled copper wire, the Recon 40 is rated for use at up to 500W SSB, 300W CW, and 200W digital (50% duty cycle). The coil body is made from Delrin and 6061 anodized aluminum CNC-machined in the USA. The coil body is 100% weather-resistant thanks to its unique design which incorporates the use of O-rings and gasket seals at each joint. Its machined wire groove provides mechanical support and optimal spacing to ensure low-loss performance.

Switching bands is made easy with the integrated weatherproof coil bypass switch. When you’re ready to move to the higher bands simply flip the switch and tune the telescoping whip to your desired frequency. The Recon 40 also features a rapid-deploy radial system. At the heart of this system is the radial “puck” that accepts up to eight 4mm banana plugs. This enables quick attachment of REZ Antenna Systems’ 4-wire radial kit (below, not included) and leaves room to expand your radial field for even better results.

Mozambique QRV in June 2024

For those still trying to add the Republic of Mozambique (C9) to your list of DXCC entities this month, there’s still a window of opportunity. The C91AHV DXpedition by CT7AHV is scheduled to run until June 15, 2024. Chasers can reach CT7AHV on 40, 20, 15, 10, and 6M in SSB, CW, and FT8.

Located in southeast Africa, Mozambique is bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Eswatini and South Africa to the southwest. It is separated from the Comoros, Mayotte, and Madagascar by the Mozambique Channel to the east. As of May 2024, Mozambique ranked as the 113^th Most Wanted DXCC Entity per Clublog.

Not Far from the Glorioso Islands

The rarely activated Glorioso Islands, which is scheduled to be on the air until June 19, 2024 thanks to the single-operator, DX Engineering-sponsored FT4GL DXpedition, lies in the northern part of the Mozambique Channel about 900 miles from Mozambique.

About Mozambique

For the sake of comparison, Mozambique (309, 475 square miles, population 35 million) is moderately larger than Texas (268,600 square miles, population 30 million). But while Texas is the second largest and second most populated U.S. state, Mozambique ranks as the 16^th largest African nation (35^th largest in the world) and the 14^th most populated in Africa. Of course this is not a fair comparison, as Africa has a population of close to 1.46 billion—which leads us to the OnAllBands Geography Question of the Day. Can you correctly list the world’s continents by population from the most to least populated? Answer below.

Bonus Question!

In honor of the letter “Q,” one of the most prominent and important letters in the ham radio world, can you name the countries other than Mozambique that have the letter “Q” in their name? Hint: There are three answers to this quagmire of a query.

QSL Cards

The active hams at DX Engineering have had great success contacting Mozambique over the years (a good reason to contact them for help with your gear if you’d like to do the same). Here are a few of the QSL cards from their collections.

Wayne, K8FF, DX Engineering customer/technical support specialist, worked C92RU in 2021.

Tom, KB8UUZ, DX Engineering technical writer, received this card from C92CC.

Dave, K8DV, DX Engineering customer/technical support specialist, reached C91TX operating from Bilene in April 2009 on 17M CW. Bilene is a beach resort town in southern Mozambique on the Mozambique Channel about 86 miles northeast of Maputo, the country’s capital and largest city.

I’ll take “Facts about the Continents” for $1,000, Ken.

So, were you able to list the continents from the most populated to the least? Got Asia, Australia, and Antarctica with no problem, huh? Yeah, we figured you would.

• Asia: 4.75 billion
• Africa: 1.46 billion
• Europe: 74o million
• North America: 604 million
• South America: 439 million
• Australia/Oceania 46 million
• Antarctica: Zero (Scientists and support staff live for part of the year in Antarctica on a rotating basis, but there is no permanent human population.)

Now to our bonus question. Mozambique has the letter “Q” in its name. Can you name the nations that also include a Q?

• Qatar
• Iraq
• Equatorial Guinea

One of the things DX Engineering always enjoys about Dayton Hamvention is the opportunity to showcase new gear, especially when these station-upgrading devices come from the innovative minds of our own team of active operators. As with many products generated from DX Engineering, suggestions from customers—as well as observations about what’s missing in our own shacks—inform us about niches that need to be filled. That’s when our team gets to work!

Today we’re featuring just a few new DX Engineering products that were on display at Dayton Hamvention 2024: RG-8X Coaxial Cable with Orange PVC Jacket, the Transmit Receive Interrupter Plug-In Module for the NCC-2, and Receive Antenna Matching Transformer.

***

RG-8X High Visibility Orange 50-ohm Coaxial Cable

DXE-8XV RG-8X coaxial cables are covered in a non-contaminating orange PVC jacket, so you get the high-performance benefits of DX Engineering RG-8X low-loss 50-ohm coax plus high-visibility that ensures your installations won’t be missed by you or bystanders. DXE-8XV cable is available by the foot; as 1.5-, 3-, 6-, 12-, 18-, 25-, 50-, and 100-foot assemblies with DX Engineering’s patented PL-259 connectors; or in a 1,000-foot spool.

Flexible and low-loss DXE-8XV RG-8X cable features a stranded copper 16 AWG center conductor and gas-injected foam dielectric with a braided copper shield. In addition to its visibility, the Type II-A PVC jacket is highly water-resistant and perfect for direct-bury applications. The cable is intended for most low, medium, and medium-high power HF operations in base, mobile, and portable applications where short runs, flexibility, and visibility are key factors.

Note: DXE-8XV Orange will fade with continuous sunlight UV exposure. Color delivered can vary.

The orange version of the cable has the same industry standard specifications as DXE-8X black jacket coax, offering significantly better handling characteristics than larger cables, excellent shielding, and lower loss than slightly smaller RG-58. Further, DXE-8XV is easily terminated with crimp connectors, including DX Engineering Next Generation Crimp-Solder 8X PL-259 Connectors.

***

Transmit Receive Interrupter Plug-In Module

The DXE-TRI-PM provides protection from station transmit energy picked up by a receive antenna connected to the DXE-NCC-2 Receive Antenna Phasing System Channel B Receive Antenna Input active front end. This optional PCB relay switch device is typically installed in the NCC-2’s top Option Slot of the Channel B rear panel board. When the transceiver keys the NCC-2’s RADIO PTT port, the DXE-TRI-PM can open or ground the receive antenna input and board output, as selected by jumpers.

The device functions independently and does not affect or depend on the settings of the NCC-2’s Bias-Tee Enable circuit that places DC on the receive antenna feedline for active antennas. The module also features a gas discharge tube to protect the front end of the NCC-2 while in receive mode. Additionally, the DXE-TRI-PM installed in the DXE-DMC-2 Dual Module Chassis can interrupt or ground any receive antenna feedline or a receiver input.

Note: Adding a second DXE-TRI-PM to the top slot of the NCC-2 Channel A rear panel is recommended for further protection.

***

Receive Antenna Feedline Matching Transformer

Enjoy the best possible receive performance with this useful device. The transformer matches your receive antenna 75-ohm output impedance to the nominal 50-ohm input impedance of most receivers. The transformer may be used in almost any receiving application that requires a 75-ohm Type F connection to a 50-ohm BNC connector. The unit boasts low insertion loss (< 0.3 dB) and excellent frequency coverage (100 kHz to 30 MHz). This feedline transformer is for use only on receive antenna systems, does not pass DC, and cannot be connected to a transmitting RF power source.

Today’s OnAllBands product spotlight shines a bright light on Alinco’s new GMRS handheld transceiver. But before we get into the benefits and features of the DJ-G46T model, let’s take a moment to discuss GMRS and how it differs from the Family Radio Service (FRS).

What is GMRS?

GMRS stands for General Mobile Radio Service—a licensed radio service that uses channels around 462 MHz and 467 MHz. From the Federal Communications Commission’s (FCC) website:

“The most common use of GMRS channels is for short-distance, two-way voice communications using handheld radios, mobile radios, and repeater systems. In 2017, the FCC expanded GMRS to also allow short data messaging applications including text messaging and GPS location information.

“The GMRS is available to an individual for short-distance two-way communications to facilitate the activities of licensees and their immediate family members. Each licensee manages a system consisting of one or more transmitting units (stations).”

An FCC license is required to operate a GMRS system, but unlike obtaining a ham radio license, no exam is required. In 2017, the FCC increased the license term from five to ten years. You may apply for a GMRS license if you are 18 years or older. If you receive a license, any family member, regardless of age, can operate GMRS stations and units within the licensed system.

Find FCC service rules for the GMRS here.

What is the FRS?

Per the FCC, the Family Radio Service is a private, two-way short-distance voice and data communications service for facilitating family and group activities. The most common use for FRS channels is short-distance, two-way voice communications using small handheld radios that are similar to walkie-talkies. An individual license is not required to operate an FRS radio provided you comply with the rules. You may operate an FRS radio regardless of your age, and for personal or business use. Channel sharing is achieved through a listen-before-talk etiquette.

The FRS has an authorized 22 channels in the 462 MHz and 467 MHz range, all of which are shared with GMRS. Each channel has a bandwidth of 12.5 kHz; power of each channel is either 0.5W or 2W.

Dayton Hamvention

While official numbers on attendance have not been released, Dayton Hamvention was another huge success by all accounts. The team at DX Engineering would like to thank all the hams who filled our booths in Building One throughout the event.

As we’ve said in past posts, making eyeball QSOs with old friends and new acquaintances, answering technical questions, and swapping stories of rare QSOs and antenna-building triumphs are always highlights.

“Hamvention 2024 is in the books and what a great event it was. Hamvention was an awesome opportunity to meet and talk to many of our customers, and we were thrilled to see so many of them, get their feedback, and share all the things DX Engineering has been working on.”

Scott Jones, N3RA, DX Engineering Sales Manager

Of particular interest were many of the vendors sold exclusively in North America by DX Engineering (DX Commander, microHAM, VA6AM band pass filters and multiplexers, et. al) and DX Engineering products like our HF+50MHz/VHF/UHF Go Box Kits (below). The kits feature Icom or Yaseu radios, Gator equipment case, rack shelving, automatic antenna tuner, and more. Troy Blair, AC8OW, DX Engineering customer/technical support specialist, handled duties at the Go Box display:

How busy was it in Building One shortly after the gates opened on Friday at 9 am?

OnAllBands will be delving deeper into Dayton Hamvention 2024 in the days to come, including a closer look at some of our favorite manufacturers and DX Engineering branded gear featured at the show.

The post Dayton Hamvention® 2024 Wrap-Up—Some Highlights from Ham Radio’s Greatest Gathering appeared first on OnAllBands.

Story by Paul Sakalas, KJ8EEP

As anyone who’s ever been will tell you:

You’ll see a lot of awesome stuff at the annual Dayton Hamvention.

And if you need proof, check out this stunningly restored 1964 Ford Econoline van wearing vintage Collins Radio livery and crammed with period-correct Collins S-Line Ham equipment.

The van was part of the Collins Amateur Radio Club display and better yet, we were able to talk with Ted Craven W0TCW, a former employee with Collins Radio, to get all the details behind the Econoline’s history.

“I was the factory service rep for Ham gear,” Ted says. “So I drove it.”

And more importantly, Ted knew the van’s origin story.

“Back in 1964, Collins bought the van directly from the Ford Motor Company,” Ted explains. “They took it to a cabinet shop in Texas, and had them completely re-do the inside. Then it went back to the Collins factory to put all the electronics in it.”

Once it was ready to go, the Ford crisscrossed the country showing off the S-Line and, when needed, it operated on the air for demo (and sometimes emergency) purposes. It attended the 1964 World’s Fair in New York—and, yes, it was at the 1966 Dayton Hamvention too.

All told, the Econoline racked up 40,000 miles between 1964 and 1966.

The van carries its own DC power, yet can also be plugged into “shore power” AC for supplemental power needs. In addition to those that are permanently attached, the van carries along extra masts and antennas in the small rear cargo area and in lockers on the roof. Out back you’ll also find the DC power distribution system and the RF amplifiers.

Collins Radio used the van up to about 1966, when it was sold into private ownership. Interestingly, the Econoline was bought by another Ham, Ed Moory W5DBR, who used it in his electronics wholesale business.

Yet since it was just an ordinary used van at the time, Moory pressed the Econoline into service doing the sort of jobs that you’d expect an old van to be used for.

“He used it to deliver appliances,” Ted laments. “He gutted it, and beat it to death.”

Thankfully, the trusty Ford’s story doesn’t end there.

The van resurfaced decades later in a condition that Ted describes as “rusted out and beat up.” Recognizing the van’s history and provenance, it was quickly snapped up by Collins Radio enthusiast Jim Stitzinger WA3CEX in the early 1990s. And as Ted tells it, the purchase wasn’t a coincidence.

“The story goes,” he laughs, “that Ed Moory’s wife called Jim and said ‘Would you get this thing outta here!'”

With the help of fellow Ham Darrel Huth WB6VHK, the Econoline was returned to its original specs both mechanically and cosmetically, with great lengths taken to ensure that its period-correct Collins Radio equipment functioned flawlessly.

Together with representatives from the Collins Amateur Radio Club, the van now travels nationwide attending regional Hamfests and other large events—including the 75th anniversary celebration of the founding of Collins Radio.

It’s even served as Special Event station W0CCX.

But our favorite part of this rig is out back, where in addition to the amplifiers, cables, and antenna storage, we’re greeted by a bulkhead crammed with signatures, callsigns, dates, and locations—each one a testament to this van’s place in history and the adventures it’s had.

As we shook his hand and said goodbye, Ted asked that we sign the van’s rear bulkhead.

It’s an honor we wouldn’t miss.

73.

The post Four Days in May (FDIM) Offers a Slice of Low-Power Heaven for Ham Radio Operators appeared first on OnAllBands.

May is the season of making “eyeball” QSOs. That’s because the Southeast Ohio area—only about three hours south of DX Engineering headquarters near Akron—transforms into the center of the ham world around the third week of the month. Three annual events make the Buckeye State amateur radio central for a handful of action-packed days:

• Four Days in May (May 15-19), billed as the biggest and best QRP event in the world
• Contest University (May 16—registration open until May 7, or when capacity has been reached), a full day of good fellowship and insights on boosting your contesting scores
• Dayton Hamvention (May 17-19), three unforgettable days of attending educational sessions, upgrading stations with the latest equipment, and catching up with old friends who arrive by the droves to celebrate the world’s best hobby

DX Engineering will be well-represented at all of the above (more about that later this month on OnAllBands). While you’ll be busy getting ready to show off your latest QRP creation, increase your contesting prowess, or capture that rare find from the Hamvention flea market, here are a few May contests to mark on your calendar: 

Straight Key Century Club Weekend Sprintathon: May 11, 1200Z to May 12, 2400Z. This monthly event “aims to bring together operators with different skill levels in a regularly scheduled, informal operating event lasting 36 hours,” per the SKCC website. The contest now includes a multi-operator category. The SKCC was established in January 2006 and is going strong with more than 28,000 members. From the group’s website:

“The Straight Key Century Club is the most active group of mechanical-key Morse code radiotelegraph operators in the world…Here’s how it works: Apply for free membership (open to licensed amateur radio operators only.) Make HF radio contacts using any of the three original types of manual telegraph keys: Straight, Bug, and Cootie. Gain on-air experience in sending and receiving by swapping numbers with other members; enter Club-sponsored sprints, contests, and special events; rag chew; earn activity and achievement awards; access our online resources, newsletter, forum, and chat.” 

Find the SKCC membership request form here.

Canadian Prairies QSO Party: May 11, 1700Z to May 12, 0300Z. This marks the third running of the CPQP, an SSB/CW event on 40/20/15/10M. From the CPQP website: “This is your opportunity to get to know your western Canadian neighbors in the provinces of Alberta, Saskatchewan, and Manitoba.”

“The Canadian prairie provinces consist of Manitoba (VA4/VE4), Saskatchewan (VA5/VE5) and Alberta (VA6/VE6),” the website explains. “Unlike most American states, these three Canadian provinces are not subdivided into counties. Instead, we have federal electoral districts. Manitoba and Saskatchewan have 14 districts each, while Alberta has 34, making for a total of 62 districts. For those who are ‘out of province’ (think ‘out of state’), your goal will be to work as many of the 62 districts as possible. For those ‘in-province’, the goal is to work everybody (13 provinces/territories plus 50 states). Note that stations within the Canadian prairie provinces can count one multiplier from every province, including their own.”

58^th Alessandro Volta Worldwide RTTY Contest: May 11, 1200Z to May 12, 1200Z. Hosted by the SSB and RTTY Club COMO and the Associazione Radioamatori Italiani, this annual event is designed to “increase interest in RTTY mode and to honor the Italian discoverer of electricity, Alessandro Volta.” Learn the story behind Volta’s amazing work in this article. And check out these OnAllBands posts from Ed Muns, W0YK, on RTTY:
