DX Engineering Sponsors September 2024 Activation of Pitcairn Island
Pitcairn Island QRV in September, 2024
One of the world’s most intriguing locations is scheduled to be on the air from September 5-15 thanks to the VP6WR DXpedition by Bill Rothwell, G0VDE. The 80-10M operation will be, per his website, on “SSB, FT8, and some RTTY” from the small volcanic island—the least populous national jurisdiction (less than 50 people) in the world and the spot where, in 1790, mutineers from the H.M.S. Bounty settled after famously burning the ship.
G0VDE will follow up the Pitcairn Island DXpedition with an operation from Mangareva as FO/G0VDE (Gambier, IOTA OC-63) from September 17-21. Look for updated details at the VP6WR website.
Hustler 4BTV 4-Band HF Vertical Antenna and DXE Installation Guide Package: The package comes with the real-world-proven Hustler 40/20/15/10M trap vertical antenna plus the essential 60-page instruction manual, which includes details on achieving maximum performance through installing a complete radial system, plus many more tips on turning this vertical into a DXing powerhouse.
The avid DXers at DX Engineering have made several contacts with operators on Pitcairn Island, as well as Ducie Island (one of the uninhabited coral atolls of the Pitcairn Islands), over the years. Here are a few of the QSL cards from their collections.
Tom, KB8UUZ, DX Engineering technical writer, reached the 2019 VP6R Pitcairn Island DXpeditionon 20/17/15M SSB. The VP6R DXpedition team battled muddy trails, challenging propagation, lightning, gale force winds, torrential rains, and even feral cats pouncing on keyboards to log more than 82,000 QSOs during their successful stay on this much-coveted DXCC entity in the South Pacific.

As the card shows on the front, VP6R received strong support from DX Engineering, which supplied the operating team with a range of DX Engineering branded equipment:
Also going along for the trip to Pitcairn Island was DX Engineering’s custom-designed 90-foot top-loaded 160M vertical antenna, featuring heavy-duty hinged pivot base (a “work of art,” according to VP6R’s Nodir, EY8MM) with custom base insulators to accommodate a 40-foot falling derrick made with three-inch diameter pipe. Originally built to handle the high winds of Bouvet Island, the antenna’s modular design allowed it to be easily downsized if weather conditions made it difficult to install at full size on the island. The crew sent us this photo of the antenna poised against a starlit sky.

Mark, W8BBQ, DX Engineering customer/technical support specialist, did some serious band-filling during the five-operator VP6T Pitcairn Island DXpedition in January 2012. He made contact on 80M, 40M, 30M, 17M, 12M, and 10M CW, and 20M, 17M, 15M, 12M, and 10M SSB.
Organized by Jacques F6BEE, the VP6T DXpedition made 56,300 QSOs in 11 days.

George, K3GP, DX Engineering customer/technical support specialist, received three different QSL cards from the January 2008 VP6PR DXpedition, each one featuring a different photo from Pitcairn Island. Dave, N8NB, DX Engineering technical support specialist, reached VP6PR on 17M RTTY.
George, K3GP, joined thousands of DXers around the world by earning this QSL card—actually, a 32-page booklet—from the 2008 DX Engineering-sponsored VP6DX Ducie Island DXpedition. The VP6DX crew logged a whopping 183,584 QSOs.
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!
What’s not to love about vertical antennas like the Cushcraft HV-4E?
Vertical antennas offer an omnidirectional signal pattern, take up very little space, and are easy to install. They do not necessarily require support structures such as trees and buildings, but it’s a good idea to guy them to prevent wind damage. Functionally, they have a low angle of radiation, which is favorable to DX. Evidence suggests that vertically polarized antennas are better for short-range (ground wave) communications.
The Cushcraft HV-4E arrived in a relatively small box, barely 38 inches long and weighing about five pounds. My UPS guy looked happier than usual, given that he’d lugged some huge boxes to the porch on past trips.
Editor’s note: MFJ, a longtime manufacturer of ham radio products, ceased production in May 2024. DX Engineering still has many MFJ products in stock, including the HV-4E and other Cushcraft and Hy-Gain items, as well as MFJ branded devices.
What Is It?
Cushcraft’s HV-4E Vertical Antennais an economical, 19-foot low-profile antenna designed to improve operating efficiency and bandwidth on 40M.
On 40M, the antenna is a center-loaded vertical. On 20-10M, it’s a top-loaded vertical. The power rating of this antenna varies from band to band with a minimum 1 kW SSB, 400W CW/digital.
(Image/Cushcraft)
The HV-4E uses parallel end resonators for automatic band-switching instead of series traps. According to Cushcraft, the high-Q top-loading resonators deliver less loss and higher gain on 20, 15, and 10 meters. Center loading on 40 meters improves efficiency and lowers the center of gravity, making the HV-4E easier to handle and increasing its survivability in strong winds.
Optional accessories include a tilt mount that lets you lower the antenna to a convenient height for tuning and maintenance.
Of course, you’ll need radials—a minimum of four for portable operation and eight or more for a permanent installation. MFJ 1932 Ground Radial Kits have two sets of four radials with ring connectors, or you can make your own.
The MFJ 1901 Portable Ground-Coupled Antenna Base is a handy mounting plate for Field Day or POTA activations.
It’s Always Something
As some early reviews mentioned, the antenna has an issue with the coil assembly.
It looks fine at first glance, but there’s a hidden problem. The coil lug connections were soldered right over the unprepared enameled wire already inserted into the lug. Given the size of the coil wire, the end should have been sanded with fine-grit sandpaper and tinned lightly with solder before it was inserted into the lug.
To be safe, you should redo all eight connections.
Construction
Other than correcting glitches, the assembly took little time and was fairly easy to accomplish with the included directions. It’s primarily small hardware installation and assembling the aluminum tubing. Plan on about two hours in addition to the coil repair.
When choosing a location, mount the antenna in a clear location above or away from buildings, towers, feedlines, utility wires, and other antennas. Always mount this antenna so that it is out of the reach of adults and children.
You’ll need some type of support on each end of the antenna while you build it. A pair of sawhorses works well, keeping everything within reach and making spoke installation much easier. Assembly can easily be done by one person. But when the antenna is ready to be mounted or moved, it’s a good idea to get some help to avoid possible damage to the antenna.
Tuning the antenna will take time—more than you might expect. Be sure your radials are in place before you begin. After the initial build, this antenna’s normal resonant frequency is at or below the bottom of each amateur band. Checking the results can be done with an SWR meter, but an antenna analyzer or Vector Network Analyzers (VNA) will make tracking changes much easier. Stand about 10-20 feet away from the antenna so your body will not detune it.
You adjust tuning by changing the length of the top section starting with 40 meters, then 20, 15, and 10. To raise the resonant frequency, you must trim a small amount off the inside end of the capacitance spokes. This requires temporarily dropping the antenna down to a level where you can pull, trim, and reinstall the spokes. The optional tilt base makes this job much easier.
Refer to the chart for initial antenna measurements and approximate the amount of spoke to be trimmed for each band in the instruction manual—it’s a good starting point. I found the information fairly accurate, and it may save you some time and additional trimming.
Getting on the Air
The first install was on a 10-foot pole in the backyard with two elevated 1/4 wave radials per band.
However, I found the antenna behaved better at ground level with eight radials I made to the MFJ 1932 kit specs. The antenna and radials were attached using the supplied U-bolts to the top of a three-foot piece of steel mast, driven into the ground. Eighty feet of RG-8X 50-ohm coaxial cable connected the HV-4E to a Yaesu FT-710 HF/50 MHz Base/Portable Transceiver in the shack.
I tuned the antenna for lowest SWR mid-band on 40-10, yielding readings of 1.3:1 or less. An unexpected bonus was that it was also resonant on 11 meters. Dust off your old CB radio and give it a try.
While on the air, I made several Kansas QSO Party contacts. I also snagged the Z36T DXpedition in North Macedonia. Not bad for a 19-foot antenna at ground level.
Impressions
Four bands, compact antenna, surprisingly good performance—it brings to mind one of the classics, Hustler’s 4BTV. Interestingly, if you look at the HV-4E page on the MFJ website, the ad compares these two antennas. I won’t discuss the merits of traps vs. parallel resonators or center loading. You can decide for yourself.
At one-third the weight of the 4BTV, the Cushcraft HV-4E is a great choice for a vacation home and could be used for POTA/BOTA activations with careful handling. You can reduce the length to about seven feet by loosening the aluminum elements and sliding them out for transport without disturbing the coils. But realize that with the lighter weight, metal parts aren’t as robust as those found on other Cushcraft verticals.
I was pleased with the on-air performance of this vertical antenna. It’s small, lightweight, easy to assemble, and effective at what it was designed to do.
It should also blend well with foliage when antennas need to be heard on the air, not seen.
Now that 13 Colonies is over, many hams will shift gears to go full throttle for an operating event that, in the words of songwriter Bobby Troup, will let you “get your kicks” on a bygone and beloved highway that still inspires worshippers of the open road.
Celebrating its 25th anniversary in 2024, Route 66 on the Air is a nostalgic blast from the past for operators who will once again attempt to reach special stations along the historic highway, which covered 2,448 miles from Chicago, IL to Santa Monica, CA. Opened in 1926 and fully paved in 1938, the route was known for its offbeat roadside attractions, thrilling landscapes, and legions of drivers who traveled its skid-marked path in search of America—or perhaps the perfect cheeseburger and milkshake.
Route 66 was removed from the U.S. Highway System in 1985.
Troup’s popular 1946 rhythm and blues song, recorded by the likes of Nat King Cole and the Rolling Stones, mentions a travelog of stops along the route, including Oklahoma City, OK; Amarillo, TX; Flagstaff, AZ; Kingman, AZ; Barstow, CA; and San Bernardino, CA—all cities that will be represented by local clubs during the Route 66 on the Air event, which runs from September 7-15, 2024.
Find the complete list of 23 special event stations and rules at the Citrus Belt Amateur Radio Club (San Bernardino), W6JBT, website. Per the website, the event was started by the Northern Arizona DX Association and taken over a couple of years later by the Citrus Belt club.

As of this posting, there’s still time to make contact with the CY9C DXpedition from St. Paul Island. The team is scheduled to operate continually until the evening of Wednesday, September 4, 2024. Don’t miss the opportunity to put this three-mile-long, rarely visited island off the coast of Nova Scotia, Canada—the 50th Most Wanted DXCC Entity per Clublog—in your logbook before the operation from the Northeast Island site goes QRT.
CY9C has been on the air since August 25.
On Monday, September 2, the team’s website reported that CY9C had recorded more than 81,000 QSOs, noting that there will be more SSB activity moving forward.
DX Engineering is a major sponsor of CY9C, having provided equipment including:
Watch Tim Duffy, K3LR, DX Engineering CEO, interview members of the CY9C team (“a bunch of MacGyvers” who have been re-engineering equipment in the ham radio spirit, according to Craig, K9CT) from the wind-swept island.
The interview was held Friday, August 30, 2024.
OnAllBands will be posting a complete wrap-up of CY9C in the days ahead.
There’s a lot to do on the air in September, 2024!

One of the great things about ham radio is the amazing variety of items that can be purchased to add more enjoyment to the world’s best hobby. Case in point: Today’s featured video on some of the latest products available at DXEngineering.com.
For more than two decades, the hams at DX Engineering have invested a great deal of time and brainpower toward enhancing the performance of Hustler BTV Series 4-, 5-, and 6-Band Vertical Antennas. This commitment has resulted in a slew of complementary DX Engineering-produced Hustler antenna products coupled with smart advice about installing ground radials for optimal results.
This combination of add-ons and operational wisdom continues to result in spectacular results for hams around the world. Here’s just one of many favorable opinions:
Five Stars (4BTV 4-Band HF Vertical Antenna): This antenna performs above and beyond what I expected! I hadn’t made any DX contacts in a very long time on the voice portion of the HF bands. After installing this per instructions and laying down 24 ground radials of various lengths due to confined space I easily made a contact into Germany through a pileup first try! Got a good 5-7 report with great audio! I also added the 17M add-on kit which performs flawlessly! Best antenna I have purchased!! Highly recommend this antenna if you are limited on space!
OnAllBands plans to cover all of the above in later posts, but first we’re checking out customer reviews of Hustler BTV Series add-on kits. In part one of this series, we explored the 17M add-on kit.
The 80M add-on is tunable for operating across a small segment of the 75/80m band with an SWR of 1.5:1 or less. Larger frequency excursions are easily made by lowering the antenna and adjusting the length of the top rod. A DX Engineering DXE-TB-3P Tilt Base Antenna Mounting System (sold separately) makes this a simple job. A good SWR meter or antenna analyzer will allow you to check the overall performance of the antenna while making final adjustments.

The DX Engineering 80M add-on kit requires no disassembly of your existing antenna. Simply add one of these kits to the top of the existing installation, make some minimal tuning adjustments, and enjoy getting on the air with an additional band. These kits come complete with Hustler RM75/80 resonator with large corona ball whip; Allen wrench for the two Allen set screws on the 80M resonator; and three-bladed spider assembly(above).
What Does the Customer Say About the 80M Add-On Kit?
Five Stars: Excellent! Simple to install and tune. Best reports ever with locals. Then worked Puerto Rico first night.
James, DX Engineering Customer
***
Five Stars: Easy to install and tune. And nice to get all the needed parts in one kit with good instructions.
Aaron, DX Engineering Customer
***
Five Stars: Easy to install, especially if you have the Omni-Tilt base on your 4BTV. Tuning was simple, took about three tries to get it centered on the frequency I wanted using the MFJ-223 analyzer. Performance with 32 radials is not bad. Expect about 45-50KHZ of usable 2:1 SWR bandwidth.
Samuel, DX Engineering Customer
***
Arrived quickly, well packed. 80M resonator and whip in one box, three-leg spider in second box shipped separately. Easy to install on my 5+ year old 4BTV. Required a bit of retuning the vertical, mostly 40M (top section was shortened a bit). SWR about 1.5:1 80-40-20M and 1.2:1 15-10M with my 36 radials. Have had a few 80M QRP QSOs so far. Signal reports about one S unit weaker than my full length 80M dipole—not bad for a shortened radiator. QRO probably better.

The historic Rig in a Box N5J DXpedition from the Jarvis Island National Wildlife Refuge is in the books. Jarvis was the 18th Most Wanted DXCC Entity per Clublog when the activation was fully underway on August 9, 2024.
Thanks to countless hours of planning, technical advancements in the hobby, amazingly skilled offshore and worldwide remote operators, sponsors including DX Engineering, and an active community of DXers, the #18 ranking will certainly take a precipitous fall when the next most-wanted list is released.
N5J marked the first activation of Jarvis Island (a dual entity with Palmyra Island) since the April 1990 AH3C/KH5J DXpedition, which logged 55,000 QSOs over ten days. The only other time Jarvis has been QRV was AD1S/KH5 in November 1983—the first time this 1.7-square-mile coral island in the South Pacific was on the air.
Along with remote CW and FT8 stations, the N5J at-island operating team of Don Greenbaum, N1DG; Mike Snow, KN4EEI; Tomi Pekarik, HA7RY; Rig in a Box innovator George Wallner, AA7JV; and Adrian Ciuperca, KO8SCA recorded more than 100,000 QSOs on 160-6M in SSB, CW, and FT8 after 11 days of operation. Additionally, 3,000 operators qualified for an N5J special award by making FT8, CW, and SSB contacts and logging QSOs on five bands.
As noted by Ann Fried on the N5J Facebook page, “All the hard work and planning did a great service to hams worldwide.”
Pierre Leroy wrote, “Keep on doing good work. Conditions are not easy but ATNO from ON6PL.”
“Thanks to the whole team for outstanding work,” wrote Tor Langvand. “Challenging propagation from time to time. Nevertheless, >100K QSOs in the book is fantastic. Great job, all.”
Gerry Hull, W1VE, posted on the N5J Facebook page the day the DXpedition went QRT, “The Magnet team is busy taking down everything and preparing for the trip back to American Samoa. They are the real heroes who powered this operation! As the Team Lead for the CW Remote Crew, I couldn’t be happier about the outcome. As an advocate of remote DXing and contesting, I’m extremely pleased how everything worked.”
From the N5J website, the team wrote, “Thank you for all the QSOs. It was a blast.”

The Impact of RIB Operations
The Rig in a Box concept, which allows self-contained amateur radio stations to be placed on land while operators work remotely, is proving to be a game-changer for DXpeditioners as well as hams trying to check off the remaining rare entities on their DXCC scorecard.

RIB-centered ventures dramatically increase the chances that decision-makers governing wildlife protected areas will grant permission for these operations. RIB DXpeditions ensure that boots will only be on land to set up, tear down, and maintain the RIB stations, reducing environmental impact and eliminating a stumbling block that has kept many entities off the air for decades.
(Image/N5J Jarvis Island)
Get up close and personal with the N5J team in this video featuring DX Engineering CEO Tim Duffy, K3LR, interviewing operators aboard the MV Magnet on August 9, 2024.
“In addition to us being here there are three Fish and Wildlife scientists that are currently on the island,” explained George, AA7JV, in the video. “They’re conducting research and working on the island. This is really the result of Don (N1DG) having worked with the Fish and Wildlife Service to convince them that amateur radio can be not just a user but a partner. And as a partner we can contribute to their efforts, and in return for that, they let us operate from these very highly protected reserves where normally they do not let anybody.”
DX Engineering Equipment 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:
The teams at DX Engineering and OnAllBands salute everyone involved in making the N5J DXpedition to Jarvis Island possible. Look for posts about more DX Engineering-sponsored DXpeditions in the days ahead.
There is no shortage of thoughts on what’s the ideal rig for making more QSOs when operating away from the home station, especially with the soaring popularity of POTA, SOTA, IOTA, BOTA, and other opportunities to have fun away from the shack.
Truth is, with so many excellent transceiver options, there’s no right answer. And if someone suggests that their answer is definitive, we suggest the following all-encompassing rebuttal courtesy of Jeff “The Dude” Lebowski: “Well, that’s like your opinion, man.”
If you’re new to ham radio or looking to upgrade your portable operating prowess, we’ve put together an informal, completely unscientific breakdown of what transceivers were used during Field Day 2024. The following is based on responses to a question posed on the DX Engineering Facebook page: “What radio did you use during Field Day?”
(Image/DX Engineering)
Like we’ve said many times before on OnAllBands, it never hurts to hear what others have to say about what works best for them. And keep in mind that the chosen radios were deployed to match a range of environments and goals—as well as price ranges.
Bottom line: Not everyone operates on Field Day the same way.
The rigs used on Field Day ranged from out-of-production radios to the latest SDR models from all popular manufacturers.
Based on more than 120 responses, the usual transceiver suspects led the pack of the most-used rigs for Field Day 2024: Icom IC-7300 HF Plus 50 MHz Transceiver
The above represents only a small portion of the diverse selection of radios put through their paces during Field Day 2024. Here some of the other Icom transceivers—many of which are no longer produced—that got a workout the weekend of June 22-23:
After seeing much success the first few years, Youth On The Air (YOTA) Camp in the Americas returned this past summer to Halifax, Nova Scotia. Approximately 30 campers from six different countries, ranging from 15 to 25 years old, attended.
Throughout the week, campers took part in sessions on satellite operating, high altitude ballooning, CW, soldering/kit building, POTA, and more—all led by other young people.
More importantly, the campers (including myself) had the opportunity to meet other young hams and form friendships that will last a lifetime.

Every YOTA camp is full of new adventures, and this year was no different.
We started planning for this year’s camp as soon as last year’s event in Ottawa ended, since planning an event through emails and Zoom meetings can be a little tedious. We started looking at details like what we would do during this year’s camp, where we’d host specific sessions on and off campus, and what sessions to have. Then we started creating the schedule.
By November 2023, we’d started writing press releases and posting information about camp to our social media to build excitement and spread the word about where and when it would be. We also started looking for young people to lead sessions, particularly returning campers from the previous years.
As we got closer to camp, we had Zoom meetings about once a month to discuss important issues and things that came up while we were emailing back and forth. It seemed like everything was straightened out and ready to go, but Murphy decided that would be the perfect time to remind us of his law:
Anything that can go wrong…will!
We arrived in Halifax the Friday before camp started and encountered a “small” problem. The pallets with nearly all of the supplies for camp were stuck at customs in Massachusetts, and the office would be closing in about half an hour.
We racked our brains for a solution and made a few phone calls.
Eventually, we connected with The Ham Radio Guy, Marvin, W0MET, who offered to drop everything, pick up the pallets, and even drive them to Maine to meet us at a halfway point so we could pick them up.
Very early the next morning, Julie Rapp and Colleen, KB8VAQ, started the 15-hour drive to Maine from Halifax while the rest of us stayed back and started setting up what we could. Finally, while we were at dinner, we got the message that Colleen and Julie had gotten through customs, crossed the border with the pallets, and would get back at about 2 am Sunday.
We all got up bright and early on Sunday and worked together as fast as we could to unload everything and set it up. We managed to get almost everything straightened out, although there would be a running joke throughout the week whenever we couldn’t find something:
“Where is X?”
“Oh, probably on the pallets!”

With setup complete and all t’s crossed and i’s dotted, camp was a go!
Campers started arriving at noon to get settled into their dorms at Mount Saint Vincent University and meet their roommates until the opening ceremony at five (watch a video of the opening ceremony here).
After the opening ceremony we had a quick tour of the shack and antennas before we could start operating. The next morning, we started the first day of camp with logging and SDR sessions. Then, the ID-52 handheld transceivers that Icom donated for us to use all week were passed out and our Icom rep, Rose, VA3RZZ, led a session about D-STAR.
After lunch, we headed outside for our pico balloon launch, led by Wintta, VA3WGY, and Stefan, VA3STQ.
(Image/Katie Campbell, KE8LQR)
Unfortunately, both balloons hit a storm a few hours later and went down just north of Sable Island.
After launching our balloons, we had sessions about nets and CW, followed by a session where campers and staff could share resources and groups for young hams. We all had dinner and then the final session of the day was “Train the Trainer,” where some of the camp staff explained how to run a YOTA camp, from planning and preparation to actually hosting the event.
Tuesday morning, campers split up into either a kit-building or ARDF session. After that, we had our ARISS contact, led by Ruth, KM4LAO. Tuesday evening, we had dinner in downtown Halifax before going on a tour of the city and the harbor. After the tour, it was back to the university for some operating time or socializing before lights out.
On Wednesday, we got to do some satellite operating before a presentation from Dr. Yaroslav “Yarko” Pustovyi about Maritime Launch Services. After his presentation, it was time to get ready to activate Georges Island the next day. Once we finished up our POTA prep, we had some more time to operate VE1YOTA or socialize.
On Thursday, it was time for POTA! We split up into groups and rotated which location we were operating from or touring. My group started out at the HMCS Sackville, where we got to tour the ship and learn more about its history before getting on the air with the station on board.
After we made some contacts there, it was time to head to Georges Island for POTA. We took a ferry over and got on the air straight away. After some antenna troubleshooting, we finally started making contacts and got a few really large pileups!
After that, my group took the ferry back and got to tour the Maritime Museum of the Atlantic and even operate from the station there. Then, it was time to go back to the university for dinner and shack/social time.
On Friday morning we had our closing ceremony (watch here), returned our radios, said our goodbyes, and started making plans to see each other at camp next year!
We’ve already started planning for camp in Denver, Colorado, and hope to see you there!

OnAllBands has been taking a close look at products that can help you get more out of your Hustler 4BTV, 5BTV, and 6BTV vertical antennas. We’ve got quite a bit of ground to cover, so we’re starting with the DX Engineering add-on kits that let you easily and effectively expand coverage. Check out this article on the Hustler BTV Series 17M Add-On Kit. Later this month we’ll be exploring what operators say about the 80M add-on kit.
Today, we turn our attention to the latest addition to DX Engineering’s lineup of devices that have turned the Hustler BTV verticals into an affordable and proven DXing juggernaut for hams around the globe, especially those dealing with limited space and HOA restrictions.
Users on eHam.net have called the DXE-AOKC-12M a “great product for the money,” “first-rate made,” “a superior product that performs, “very easy to assemble,” and “a straightforward way to add 12M to the Hustler without it looking like a Rube Goldberg contraption.” Check out all the reviews at eHam.net.

The RF power handling of the DXE-AOKC-12M 12 Meter Add-On Kit is conservatively rated for 1,500 watts PEP SSB, 1,000 watts CW, and 375 watts RTTY and Digital modes (including FT8) at an antenna SWR of 2:1 and below. This rating is for 12 meters only; it does not apply to BTV antenna trap or resonator frequencies where the use of less power is advised.
A Note About Installing Both the 17M & 12M Add-On Kits
The 17M and 12M kits work together because they do not interact with each other. Further, installing them on your BTV antenna will not drastically affect other bands. The 17M and 12M kits match each other, except for the coil on the 17M, and they add negligible wind loading to the antenna. The kits can mount on opposite sides of the Hustler BTV vertical and may be installed at the same time or at different times.
TIP: The use of the OMNI-TILT base is recommended for BTV ground mounting when both 17M and 12M kits are installed.
The 12M add-on kit includes:
Pre-assembled 12M element wire with soldered ring terminals
Four stainless steel band clamps with threaded studs
Upper insulated bracket
Two 14-inch tuning rods
Bottom aluminum stand-off bracket
Spring-loaded end insulator for the 12M element wire, which lets the antenna move naturally
Scotch-Brite® pad for cleaning the 12M element connections to the BTV antenna
Stainless steel hardware
Tuning the 12M Add-On
Installation of the DXE-AOKC-12M can have the effect of narrowing the SWR bandwidth of 20, 15, and 10M—a reasonable tradeoff for adding the extra band. After the 12M kit is installed and tuned, any required shift to the usable SWR frequency ranges on those bands can be accomplished by trap sleeve repositioning on the respective band trap. SWR may be optimized for CW and Digital or SSB segments by careful trap sleeve tuning adjustments.
For more about tuning, assembly instructions, and further details, read the DXE-AOKC-12M manual. Visit DXEngineering.com to order this impressive Hustler upgrade.
It has become apparent over the years that many folks who love everything about ham radio also love their cars, trucks, motorcycles, and ATVs. This is supported by the fact that there are plenty of DX Engineering customers who also do their shopping for suspension systems, exhaust tips, piston sets, and fuel injectors at Summit Racing Equipment. In fact, we’ve lost count of the number of letters we’ve received from those who relish both turning corners and turning knobs.
For those who don’t already know, Summit Racing has been the parent company of DX Engineering ever since the aftermarket automotive parts giant acquired the ham radio manufacturer in 2000. (Look for much more about DX Engineering’s 25th Anniversary celebration in the months ahead.)
DX Engineering shares headquarters with Summit Racing in Tallmadge, Ohio, near Akron. The updated DX Engineering Amateur Radio Showroom is housed inside the Summit Racing Retail Superstore at the same location. Ham radio gear can also be purchased at the Summit Racing retail store in Sparks, Nevada.

Hams & Gearheads
At first inspection, automotive enthusiasts and ham radio aficionados may seem to have little in common. But look closer. The hobbies and the people who are passionate about them share a lot more than you might think.
A Need for Speed
Summit Racing is appropriately known as “The World’s Speed Shop®,” the place where you can find millions of go-fast parts to soup up your ride for the street, dirt track, road course, or drag strip.
While transceivers don’t come equipped with a finish-line parachute, speed is still very much a part of the hobby for scores of amateur operators. Many hams were first intrigued by the idea that their transmissions could reach across the globe thanks to radio waves traveling at the speed of light—186,000 miles per second (a tad quicker than your average quarter-mile pass). Elite CW practitioners hone their skills to reach mind-boggling speeds up to 60 WPM. Like a road race, marathon radiosport contests, such as the 24-hour World Radiosport Team Championship, become a test of both operating speed and endurance. Other ham radio activities, such as direction-finding competitions, depend on quick wits and speed when searching for hidden transmitters.
Finally, we know gearheads and hams alike don’t like to wait around their garages and shacks for parts to arrive—so you can expect speedy delivery of what you need—when you need it.
A Need to Build…and Rebuild
Whether completely restoring a classic, modifying a late-model muscle car, or creating a one-of-a-kind rat rod, there is nothing that makes a gearhead happier than wrenching on their latest project—permanently oil-stained fingernails be darned! Hams are no different. While getting on the air may be the ultimate reward, the satisfaction of installing an antenna, adding a new rotator, or building a homebrew amplifier ranks high for the hands-on ham.
Ask a gearhead or a ham how they spent their early years and you’ll hear stories of disassembled vacuum cleaners and radios, spare parts strewn across living rooms, and angry parents (though secretly proud) admonishing them for not asking first. The obsession to find out what makes things tick runs deep in both hobbies.
Ask a certain type of gearhead “How many vehicles are enough?” or a similarly inclined ham “How many radios are enough?” and you’re likely to get a shrug. Why? Because there simply isn’t a way to quantify an answer for those whose thirst for rides and rigs have no boundaries.
As of January of 2024, it was reported that Jay Leno’s vehicle collection consisted of over 180 cars and 160 motorcycles. Jerry Seinfeld’s cache of cars exceeds 150, including more than 40 Porsches. For those less monetarily endowed, it’s still difficult to turn down a project vehicle regardless of condition or space limitations. Same goes for hams who can’t pass by a hamfest flea market without adding another vintage rig to their collections or peruse DXEngineering.com without adding the latest SDR model and companion gear to their shopping cart.
Attend a car show or a day at the track and you’ll discover that competitiveness and camaraderie go hand in hand. Trophies and trips to the winner’s circle are nice, but longtime gearheads will tell you it’s the friendships with other enthusiasts that count most at the end of the day. Need proof? Listen to a couple of strangers become fast friends as they ease into a “bench racing” give-and-take or share stories of the “cars that got away.” Hams have the added benefit of being able to make friends from all parts of the world simply by getting on the air and calling CQ. Goodwill is at the core of what it means to be an amateur operator, whether hanging out with your club on Field Day or rag-chewing with an operator thousands of miles away.
Some Quick Comparisons
Going mobile: The most obvious merging of the two pursuits is equipping your vehicle with a mobile transceiver for fun on the road as well as serious emergency communication.
Endless variety: Both hobbies offer so many avenues of interest that it’s impossible to do it all at once. As the bloggers at OnAllBands have recommended time and again, if you’re starting out in ham radio, it’s best to initially pick one aspect of the hobby rather than spreading yourself too thin.
Passing it on: Like fathers, mothers, grandparents, and uncles who share their passion for car culture with their sons, daughters, grandkids, and nephews, ham families can’t help but pass on their love of all things radio to the next generation of operators.

When DX Engineering acquired Hi-Z Antennas’ lineup of HF receiving array products in 2022, the company’s research and development team went to work to make sure Hi-Z’s most popular devices would continue to be available to amateur operators worldwide.
The goal of this ongoing effort has been to roll out Hi-Z-inspired devices that retain the functionality of the original designs while making significant electronic and mechanical improvements. The evolution of these updated receive array devices includes efficient production, superior durability, and smoother operation.
DX Engineering is pleased to announce the release of Hi-Z Manual Directional Consoles—specialized BCD grounding switches that are specifically designed to operate Hi-Z Phasing Combiner relay units, also known as Phase Controllers.
Each HIZ-MDC console controls the phasing and direction selection of only Hi-Z Antennas Receive Vertical Antenna arrays and supplies power to the array element amplifiers. Consoles feature a large rotary switch knob and green LEDs arranged as receive array directional azimuth indicators with corresponding compass bearing degree markings on the front panel. The MDC-4 that controls the four-element Hi-Z Four Square Receive Array is below.

Selection of a specific model Manual Directional Control Console is required. Choose the model that corresponds to the desired version of Hi-Z Antennas Receive Array Phasing Combiner or legacy Phase Controller. Each console serves as a replacement for legacy, discontinued Hi-Z manual Shack Switches, and for the discontinued Hi-Z SS-2 and SS-2PLUS:
HIZ-MDC-4 works only with the multiband Four Square Arrays PC-4A and PC-4ELEMENT.
HIZ-MDC-6 works only with the multiband Three Element Six-Direction Triangular Arrays PC-3A and PC-3ELEMENT.
HIZ-MDC-8PRO works only with the 85/113 ft. diameter multiband 8 Circle Arrays PC-8PRO and PC4-8PROUP/PLUS.
HIZ-MDC-8 (below) works only with the 200 ft./100 ft. diameter monoband 8 Circle Arrays PC-8, PC-8A, and PC-8B.

Stainless steel chassis with cold-rolled steel black powdercoated lid
Large, easy-grip rotary switch with end-of-rotation stops
The required multi-conductor array power and BCD control cable (purchased separately for the required number of conductors and length to the array) passes through a grommet on the rear panel and is connected internally
A rear panel 2.1mm +13.8VDC power connector accepts the included mating 2.1mm plug and unterminated DC power cable for connection to a user-provided +13.8VDC 1A fused, well-filtered power supply
An Important Note About Receive Antenna System Performance
The performance of a receive antenna system can be dramatically improved when the array elements are placed where RF noise is minimal. One of the most important aspects of the installation is to maximize the array’s distance from any structures, towers, transmitting antennas, metal buildings, large trees, and fences that induce RF noise or affect the antenna field.
Preserving the array directional pattern requires that we ignore the temptation to position the receiving antenna closer to the station, based on coaxial cable loss or control cable cost. RF loss is negligible on 160 and 80 meters with up to 1,000 feet of economical RG-6U feedline. Therefore, the control cable must be chosen for the conductor size necessary to deliver sufficient voltage at the current required by the phasing combiner and element amplifiers, despite the higher cost. The benefits of the investment in the appropriate control cable for a well-placed, far-away receive antenna array are the immeasurable profits of significantly improved reception.
A convenient chart in each model’s manual will help you choose a control cable conductor size based on the distance to the array and the resulting voltage drop with maximum current flow through the supply and ground return conductors.
Hams looking to add Tristan da Cunha —a collection of volcanic islands in the South Atlantic Ocean—to their list of DXing conquests may get an opportunity in the days ahead.
W7GJ reported that he would be operating from IOTA AF-029 the last week of August and into September, but a check of the DXpedition’s website, as of this posting, now has the dates as September 26 to October 25, depending on shipping schedules and very limited space availability on ships sailing from Cape Town, South Africa. The 6M ZD9GJ operation will mainly focus on EME, with some SSB and FT8 activity.
Only accessible by boat (about a six-day trip from Cape Town), the British Overseas Territory of Tristan da Cunha is the world’s most remote inhabited archipelago—about 1,700 miles off the coast of Cape Town, 1,500 miles from Saint Helena, 4,000 miles from Argentina, and 2,500 miles from the Falkland Islands. It lies 1,400 miles northwest of Bouvet Island—the most remote uninhabited spot on the planet. This makes Tristan da Cunha the closest inhabited land to Bouvet.
The archipelago, which experiences mild temperatures, little sunshine, and lots of rain, is made up of 38-square-mile Tristan da Cunha; the wild reserves of Gough Island and Inaccessible Island; and uninhabited 1.5-square-mile Nightingale Island.
A travel article from Business Insider placed the population of volcanic Tristan da Cunha at around 230. Inhabitants of Edinburgh of the Seven Seas (the only settlement on Tristan da Cunha, below) were forced to flee in lobster-fishing boats to neighboring Nightingale Island after an eruption of Queen Mary’s Peak in 1961 destroyed their settlement. They were resettled in England, but most returned two years later to rebuild on the island.
The island features a school, churches, the Tristan Thatched House Museum, a supermarket, administration building, and an invasive mice and rat population that nightly feeds, without natural predators to stop them, on seabird eggs and chicks. A community tradition known as “Ratting Day,” which began as a way to reduce the island’s rodent population, has evolved into a competition in which teams compete to catch the largest number of critters, with honors also being given to the team who produces the rat with the “longest tail.” One academic article noted that “Black Rats…reached the island from a shipwreck in 1882.”
A single road connects Edinburgh of the Seven Seas with the island’s communally owned potato farms. Transportation is provided by a few privately owned vehicles and a bus.
The avid DXers at DX Engineering have made several contacts with operators who have received permission to operate on Tristan da Cunha over the years. Here are a few of the QSL cards from their collections.

Dave, K8DV, DX Engineering customer/technical support specialist, contacted ZD9T in November 2010 on 30 and 12M CW. The QSL card shows a drawing of a northern rockhopper penguin (known by islanders as “pinnamin”). The flightless birds breed on all islands in the Tristan da Cunha group. Read much more about the northern rockhopper penguin and everything else you’d want to know about this fascinating archipelago at the Tristan da Cunha website.
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!
Looking for a versatile transceiver that’s perfect for roving during VHF contests, drive-up SOTA operations, Super High Frequency activity, everyday use in your home station, and a whole lot more? You’ll find all this and loads of fun with the Icom IC-905 VHF/UHF/SHF All Mode Base/Portable Transceiver, says Michael Murphy, KI8R, who covers the features and benefits of this rig in the video below.
Key Features & Benefits of the Icom IC-905:
The IC-905 features a separate controller and RF module, allowing for the installation of the weatherproof RF module near the antennas. A LAN cable makes the connection between the controller and the RF module, significantly reducing power loss. PoE (Power over Ethernet) technology provides flexibility and simplifies the installation of the RF module.
Vibroplex, which first manufactured and sold its signature Morse code “bug” key back in 1904, is the longest continually operating ham radio equipment provider on the planet, but that doesn’t mean the venerable company doesn’t have more than a few new tricks up its well-worn, rolled-up sleeves.
DX Engineering’s Rod Ehrhart, K8RR, caught up with Scott Robbins, W4PA, Vibroplex’s owner since 2009, at Dayton Hamvention 2024 to discuss the mAT-TUNER line of automatic antenna tuners, which the Knoxville, Tennessee-based company has distributed in the U.S. since 2019. Watch the video below:
Scott, W4PA, highlights two new mAT-TUNER offerings—mAT-50 Automatic Antenna Tuner and Coupler Packages and the 1500PRO Automatic Antenna Tuner, both available along with the entire mAT-TUNER lineup at DXEngineering.com.
The multipurpose, 1.8-54 MHz mAT-50 Automatic Antenna Tuner comes with either an Icom, Yaesu, or Kenwood coupler and corresponding control cable. This remote tuner has the capability of matching a variety of impedances and antennas including long-wires, dipoles, verticals, Yagis, whips, and virtually any coax-fed antenna. It features a maximum input power of 120W SSB/60W Digital.

Install the sturdy, weather-resistant tuner outside near the antenna. Then install the coupler inside near the transceiver to provide power for the tuner and control its operation. The tuner does not require a control cable between the remote tuner and coupler, making installation simple. The only required connection between the antenna tuner and coupler is one 50-ohm coaxial cable. Advanced technology employed in the tuner delivers stable performance and excellent anti-interference capabilities for convenient one-key tuning.
The mAT-50 can also be used as a universal tuner for all transceivers if a mAT-50-Y or mAT-50-M coupler is connected to an external DC power supply (not included) and a control cable is not installed. You can then operate the tuner manually.
The mAT-1500PRO Automatic Antenna Tuner is an upgraded version of the original mAT-1500 tuner. Improvements include reduced weight, high- quality housing, and additional interfaces for Yaesu, Icom, and Kenwood transceivers and their corresponding operating modes. This allows the tuner to be controlled directly from the transceiver, reducing the need for manual operation.

In addition, two antennas can be connected simultaneously, and the corresponding buttons for switching (in receive mode) are placed on the front panel for easy access. Other features include:
Designed for modern transceivers with a frequency range of 1.8-54 MHz
Rated for up to 1,500W SSB/800W Digital
16,000 memory locations
Fast tuning—found values for a frequency are stored in the memory, enabling adjustments as quick as 100ms
Loop-through of the PTT line makes it possible to loop in the power amplifier behind the tuner. The tuner interrupts the PTT line to the power amplifier during the tuning process. This avoids tuning with high power, greatly reducing the possibility of damaging the tuner relays.
6 to 1,000 ohms tuning range, which corresponds to an SWR range maximum of 10:1. This allows it to match all coax-fed antennas such as a G5RV with a balun at the transition between two-wire ladder line and coax cable, but also a wideband vertical antenna designed for the rated power.
