ATU-10 from Banggood.com
by Barry (KU3X)
There are times I find myself in need of an ATU. One example is when I use my half wave end fed 40. I can not always erect this antenna in the clear. I did purchase the LDG Z100 Plus 705 with interfacing cable. The unit does as advertised but I am not impressed with its performance. My biggest complaint is, when interfaced and the IC-705 tells the LDG to tune and it does not know the antenna is matched and resonant, the LDG adds capacitance and inductance which actually raises the SWR. It’s too dumb to go into bypass. I resolved this by not using the interface cable. Now I only tell the LDG to tune where needed. Most of the time I turn the LDG off by toggling between bypass and tune using the button of the front of the unit.
Size matters to me and the LDG ATU is too big. Another downside is it uses SO-239 connectors instead of BNC connectors. Everything I have relating to QRP operating uses all BNC connectors, including my home brew two position antenna switch. I do want to get my hands on an Elecraft T1 ATU but Elecraft can’t get the parts from the manufactures to make them. So the hunt was on for a small ATU with internal batteries and BNC’s instead of the dreaded SO-239 connectors. Here is what I came up with.
I ordered the above pictured ATU-10 from Banggood.com. I have also seen them posted on Amazon.com. They can be found on eBay as well. I did not provide a link for ebay because some ebay adds are dated. There is a very good demo posted on YouTube. Here is an overview of the ATU-10 [PDF].
My ATU-10 arrived 11 June 2022. Here are my findings:
The package contained an Allen wrench and a USB cable for charging the battery as well as for updating the firmware. The package DID NOT include the interface cable for the Icom 705 nor did it included any paperwork…….no manual! My battery showed about half charged and firmware version 1.4 was installed. If you forget to charge the battery and go on site with a dead battery, you can supply power to the ATU-10 via the USB charging cable. You may have to give it a few minutes for the batteries to take a little charge, but from that point on just leave keep the ATU-10 connected to the USB cable.
The needed interface cable is nothing more than a stereo audio cable with 1/8″ male plugs on both ends. But, the ATU works without the interface cable, it’s just not controllable from the radio. As for the matching, I can say it works as good as or as bad as my LDG Z-100 Plus. Where ever the LDG provided a match, so did the ATU-10. On 80 meters where the LDG did not do so well, neither did the ATU-10.
I first tried the ATU-10 without the interface cable. I just sent a carrier from the radio and the tuner went into the tune mode. It’s that simple. It takes anywhere from 2 to 5 seconds to find a reasonable match.
To use the ATU-10 with the interface cable, there is the setup procedure. Hook up all of the cables, including the interface cable to the IC-705. Now turn the ATU-10 on. Once booted, turn on the IC-705. Go into the, “Function” screen and tap the, “tuner” icon. You are ready to go. You do not have to change modes to have the ATU-10 go into the tune mode. In any mode on the radio, like SSB, just key the mic and the tuner will tune. Give it a second or two and you are ready to go. Change bands and key the mic, same results. I lost communication between the radio and the ATU-10 when I went to 80 meters. I have no idea why? I just turned the radio off, then back on and everything was reset…ready to go.
When I received my ATU-10, I noticed all of the hardware was not that tight. I retightened each nut and Allen screw.
Size…the ATU-10 is small enough to carry in your shirt pocket ( 5″ x 2-3/4″ x 1″ )
Antenna connections… BNC. All of my cables used when I set up portable use BNC connectors.
Power source ….the ATU-10 has two internal rechargeable batteries so no external power source is needed. Since the ATU-10 uses latching relays, the only power that is needed is for the display. The display has a time out timer and the ATU will turn off after 30 minutes on non use. The ATU will last you for months on end before needing to be recharged.
Display… the display shows SWR, power out and the state of charge for the internal batteries. It also shows what firmware is installed. The display will fall asleep after 5 minutes of non use. If power is applied, the display will wake up. The entire ATU will turn off after 30 minutes of non use.
Bypass mode (simply turn the ATU-10 off)
Construction…..the ATU-10 is built inside of a solid metal enclosure.
Cons:
Loss of communication….more than once communication was lost between the radio and the tuner. Easy fix by turning the radio off and then back on but this is very inconvenient.
No manual…..not even a little sheet of paper showing the specs. Whatever you need to know can be found on this site: ATU-10 info at GitHub.
Final notes:
For the price, it think this is a great buy. It does exactly what I want it to do and provides a reasonable match to make the radio happy. You can use the ATU-10 with any radio at power level of 10 watts or less. It’s a perfect size for backpackers. I don’t think the interfacing between the radio and the ATU-10 is all that importable. I myself choose not to use the interface cable. Since the tuner will go into a tune mode if the SWR is too high, that’s all that is really needed.
You might recall from my previous field report that I took the family on a camping trip at New River State Park in April 2022. During that trip, I made an activation of New River each day and also fit in a very fun SOTA activation (click here to read an overview).
Note that anytime you’re performing an activation over multiple days at any one park, you can only have one activation per UTC day.
“Look at this, Tom! Only the stuff I need and nothing more,” cheerfully noted my good friend and Elmer, Mike (K8RAT). It was Field Day two decades ago, and Mike was gazing at his TEN-TEC Scout. I glanced over, and agreed. “So simple and so effective,” Mike added.
I’ve never forgotten Mike’s sage words. That Scout (Model 555) was about as simple as a then-modern HF transceiver could be: it had a total of three knobs––one for AF gain and IF bandwidth, one for RIT and Mic gain, and an encoder. It also had three mechanical switches on the front: one for power, one for TUNE and NB, and one for CW speed and RIT. It also had an analog SWR/power meter. The Scout used plug-in band modules for each HF band and featured a large segmented bright green LED frequency display that was characteristic of so many TEN-TEC rigs of the day.
And Mike was right. For those of us who appreciate radios with a simple, uncluttered, and an almost utilitarian interface, the Scout was, in vintage parlance, “the bee’s knees.” And that the Scout also performed beautifully was just icing on that cake.
When the Scout first appeared in 1994, embedded menu options and spectrum displays were not yet commonplace among amateur transceivers. Embedded menu items can open the door to near granular level control of your radio’s functionality and features. Then again, if those embedded menus aren’t well thought out, it can lead to awkward operation practices in the field, during a contest, or even during casual operation.
As a radio reviewer, I spend a great deal of time sorting out embedded menu functionality and design. Perhaps it’s for this reason that I so enjoyed reviewing a radio that bucks this trend and reminds me of a time that was simpler, not to mention, easier.
All of his transceiver kits are available at his website WA3RNC.com.
I was first drawn to the TR-35 after reading the opening paragraph of the product description:
“Compact but powerful 4-band, 5-watt CW transceiver kit that uses no tiny push buttons, and without those seemingly endless and hard-to-remember back menus. There is a knob or a switch for every function!”
Sold!
I considered buying and building the TR-35 kit, but I wanted my eventual review––this one!––to focus on the radio’s functionality and performance. So a factory-assembled and tested unit was right for this purpose, just so that any performance issues wouldn’t be a result of any shortcomings in my kit building skills.

Nova Scotia POTA After-Action Report
by John VE3IPS
We had planned a vacation trip out to Nova Scotia to get our lobster fix. As I always do, I prep my radio with local repeaters, look up local radio clubs, museums and check the POTA and SOTA map for locations to operate from.
I noticed that several park locations had not been activated. Thus I had an opportunity to be first activator and to get some much needed Nova Scotia parks in the Hunters logs. I printed the map and noted the park identifiers. I decided to just activate the parks that were never activated. I could have worked more parks but you have sights to see and can’t be behind the mic all the time. My antenna was prepped to be rapidly deployed in a few minutes and torn down accordingly.
I also was able to attend the Halifax ARC Hamfest on June 4, 2022.
So a vacation with ham radio elements to keep me excited with some objectives in mind.
We did visit Peggy’s Cove, Burnt Coat Head to watch the tides in the Bay of Fundy, local wineries, Lunenburg (a movie shoot was underway), the Halifax Citadel and of course eat lobster every day. I spent over $200 in gas as we did a lot of driving around (gas is just over $8 a gallon CAD), retail tax at 15% and prices for food and restaurants up by 30%. Nova Scotia is a bit more expensive than other cities.
I decided to bring my Icom 705 with a LifePO4 battery to offer 10 watts instead of the FT-891 or FT-818. Why? Because it offered a voice memory for calling CQ Parks, built in SWR meter and better IF filters over the FT-818. I wanted to cover the Marine and VHF/UHF repeaters as well and that ruled out the FT-891.
Due to the Kleenex box form factor I ended up using a Lowe Pro Omni Trekker camera bag to use as a carry on. This included a Nikon V1 camera and Binoculars.
I’m often asked if I ever charge my LiFePo4 batteries in the field via solar energy.
Truth is, I’m a big fan of solar, but I’m rarely in the field long enough to need to recharge my batteries via solar when performing SOTA and POTA field activations. It’s easier to charge them at home in advance (often via the solar system at our QTH).
In fact, one of my 3 Ah LiFePo4 Bioenno batteries can easily take me though 3-5 activations or possibly more, depending on the length of the activation and the rig I’m using.

For longer forays into the field, however, I love going solar.
Indeed, every few years, my family will stay in an off-grid cabin on Prince Edward Island (Canada) for up to 6 weeks at a time. Solar is the only practical way to stay on the air that length of time.
Of course, I also like having a solar option, when doing proper primitive/off-grid tent camping.
In the past, I’ve used a very simple portable solar charging system based on a variety of rigid and folding panels, a Micro M+ charge controller, and sealed lead acid batteries. The batteries are of course heavy, but they work brilliantly for fixed operations.
These days, I’m fully invested in LiFePo4 batteries and my Micro M+ charge controller is not really designed to pair with the BMS (battery management system) in my Bioenno packs.
I contacted Buddipole with a few questions about the unit and to find out when they would be in stock again (at the time, they were on back-order and indeed they are at time posting this report).
A number of readers and friends here and in the SOTA community are simply chuffed that Countryfile on the BBC recently featured a short segment about Flat Holm, its historical ties with Marconi, and modern portable amateur radio.
I tried my best to view this yesterday from the US, but shows like this on BBC One are geo-blocked via the BBC iPlayer…which is, evidently, clever enough to recognize VPNs.
However, I notice the segment has recently been posted on YouTube, so if like me you’re outside of the UK, I encourage you to watch it quickly before it gets pulled.
Recently, I have had the desire to try my hand at winding toroids. They have always been a mystery to me. Today’s project is winding a toroid for 40-10 meters. My target antenna is one I learned from Thomas, K4SWL. It is a random wire antenna that is 29.5 long with a 17 foot counterpoise. It is a great antenna and works well at park campsites. I either string it up in a tree or I use my 20′ B&M fishing pole.
Thank you for sharing this, Scott. I’ll be the first to admit that I can hardly take credit for the antenna design as it’s been out there for ages, but I do love this simple antenna and it has become an invaluable member of my field antenna arsenal.
I, too, have been planning to build a 9:1 UNUN and pair it with the speaker wire antenna just to make that match a little easier.
Thanks so much for sharing this and your excellent build notes!

Exploring the 7 Lakes Wilderness Area
It was as a dark and drizzly morning as my XYL (Sharon) and I (Paul) went up to Cripple Creek, Colorado, and then drove down the Gold Camp Road. The colorful Aspen trees were changing color and even in the drizzle had brilliant yellow and red colors. We proceeded up Fire Road 376 to 11,000 feet, The entrance gate to 7 Lakes. The South Slope Ranger opened the gate for us and checked our registration. I got out the rain and snow gear and got my poncho on.
(My radio is waterproof).
I don’t normally operate in the rain and snow but this area is available only by pre-registration. The day I picked happened to be a Hurricane remnant day.
The area was just opened to the public this year and there are only 20 cars authorized per day. The area has been closed to the public since 1913–before wireless! This was opening day so I picked the Special Call Sign, ‘W7L’, to operate with because it is the tri-graph of the name of the area, Wilderness 7 Lakes.
We set out on the trail for Mason Reservoir. As we arrived at the reservoir a snow cloud descended on us accompanied by thunder snow. There were 6 people there already fishing. They said fishing was great, mostly ‘catch and release’. One of the lady fishermen saw the big 10 foot whip on my back pack and asked me if I would like her spot on the lake to fish. I told her I was working ‘catch and release’ on 20 meter CW and I didn’t have a fishing license.
The radio I was using was my 30 pound PRC319 backpack radio which runs 50 watts.
The trail head has a new restroom and a covered picnic table area with one tree nearby for picnic table operations. This is a deep valley (That’s where most reservoirs are kept). So you might need more than 5 watts to get over the hills.
If you have ever taken the COG Railway out of Manitou Springs to the top of Pikes Peak, you have probably seen this area from the “Son of a Gun” Hill.
Warnings: These are high altitude trails; you must be in good physical condition to hike. Elevations at 7 Lakes range start at 11,000 feet; if you are arriving from a low elevation consider acclimating at 6,000 feet for one or two days.
Bring plenty of water and pace yourself. Altitude sickness is common. Symptoms can be shortness of breath, nausea, dizziness, headache, dyslexia. Also Loss of clear thought processes like: locking your keys in your car (This happened to one of the fishermen), leaving your log on a rock, forgetting how to program your radio, forgetting your operation time schedule or what the upper band limit of the 17 meter band is.
WG0AT, Steve, was with me on my second trip and he made this cool video:
Wow, Paul! That sounds absolutely brilliant! And taking a PRC-319–? Wow! What a way to add a little extra challenge to your high altitude radio adventure!
Friends, I’d like to share some good news with you!

The long version:
In the past, I’ve mentioned in posts that email from readers and subscribers (of both QRPer.com and the SWLing Post) has increased to a point that I can no longer keep up with them. It became very evident when I went camping in West Virginia last month and came back home to find no less than 60 messages in my inbox. These 60 messages were all ones needing some sort of reply or acknowledgement–they didn’t include notifications and SPAM.
I take pride in replying to each and every message I receive, but sadly I can no longer keep up with the volume. Sadly, I don’t have enough time especially with my busy family life.
In fact, I realized recently that replying to emails is actually taking a large bite out of the time I have to do content creation. I can’t let that happen, because that could quickly lead to burn-out. Both of my sites are pure labors of love and I enjoy them immensely.
