Many thanks to Fred Osterman and Dave Zantow for sharing information about the new CommRadio CTX-10 transciever. Here is the description from Universal Radio’s catalog:
AeroStream Communications near Golden, Colorado entered the hobby radio market in 2013 with their revolutionary CommRadio CR-1 and follow up CR-1a SDR receivers. The success of these innovative radios left many asking for a transceiver of similar size and capability.
The answer is the just announced CTX-10.
The CommRadio CTX-10 blends high performance, internal SDR technology, high efficiency circuit design, compact size and simple operation. This multi-mission QRP radio is ideal for field use and emergency operations. Transmitter covers 160-10 meter amateur bands with output power adjustable from 1 to 10 watts. The new design uses ruggedized land mobile power amps in push-pull. Every aspect of the radio design is optimized for low power consumption.
The efficient and sharp OLED display is readable in low or high lighting conditions. The radio has three built-in #18650 3.7V 2600 mAh Li-ion batteries providing 28.8 watt-hours of operation. A built-in intelligent charger provides seamless power management.
The general coverage receiver section uses multiple preselectors for optimized reception from 200 kHz to 30 MHz. An integrated CW reader and antenna tuner enhances portability. The premium tuning knob optical encoder is rated at a million revolutions.
Entire enclosure is aluminum with metal knobs and front panel. External connections are through-hole mounted for durability. Includes USB cable, DC power cord and manual. DC power requirements: receive 1.5 W, transmit 20 W. This quality device is robustly built in Colorado, U.S.A.
I’m really looking forward to reviewing the CTX-10. If the CR-1 and CR-1a are indicators, this could be a very well-built unit with a top-notch receiver!

As seen from the Overmountain Victory Trail: The Revolutionary War encampment at the Museum of North Carolina Minerals.
As I mentioned in a previous post, what I love about the National Parks On The Air program is that it combines two of my favorite things: national parks and ham radio. My family visits national parks regularly, so it’s easy for me to pack a small radio, do a quick NPOTA activation all while incorporating non-radio activities that the family loves.
Normally, I would set up my station somewhere close to the Museum of North Carolina Minerals which is situated at the junction of these two National Park entities. Saturday, however, was a special event at the museum: a Revolutionary War Encampment.
The Museum is located at Gillespie Gap, an important stop for Revolutionary War fighters on their way to the Battle of Kings Mountain. Each September the Museum hosts an encampment of re-enactors who assume the role of the Overmountain Men, primarily Scots-Irish settlers from Eastern Tennessee and Western North Carolina who came “over the mountains” and ultimately defeated the left wing of Cornwallis’ army at Kings Mountain, South Carolina. Many historians mark this victory as the turning point in the Southern Campaign of the Revolutionary War.
My family loves living history events.
Radio time!
The Park Ranger kindly gave me permission to do the NPOTA activation, but not at the museum itself. She was trying to keep the site set in the Revolutionary War period–a ham radio operator using a portable transceiver doesn’t exactly fit that description. Instead, around 15:30 UTC, I hiked up the Overmountain Victory Trail in search of an operation site near the Blue Ridge Parkway road.
The trailhead was a little rough and overgrown. I didn’t have to trail-blaze, but I did have to wade through a lot of weeds with my gear and my canine companion, Hazel, on leash. It’s times like this I truly appreciate such a compact, lightweight, and packable station.
Can you find the trail in this photo?
Once we entered the woods, though, the trail improved. I found a fantastic spot to operate between the museum and the parkway.
Hazel the dog is a welcome companion does a wonderful job keeping my site free of black bears. She’s patient, too. I typically tie her leash to a small stake or tree next to me and she promptly takes a nap. Here she is admiring my new REI Camping Stool:
You can see part of the EFT Trail-Friendly antenna hanging in this photo.
Setup was quick. I managed to raise the EFT Trail-Friendly antenna in record time. I connected the antenna to the Elecraft KX2 and was on the air, calling CQ on 20 meters in a matter of minutes. In the space of 15-20 minutes, I only managed to work a few stations on the 20 meter band even though I had been spotted several times on the DX Cluster.
I moved to the 40 meter band and logged contacts quickly, however.
My full station and my ferocious guard dog, Hazel.
Hazel, as I mentioned, is a great companion that’s sweet to everyone she meets. She’s happy to hang with me even if I’m just sitting there operating radio for an hour. She’s quiet and doesn’t bark unless she notices a true disturbance.
Still, Hazel does get bored. After I had logged about 20 stations, I heard her gnawing on something. I turned around and discovered that she found the reel of fishing line I use to hang my antennas.
Note to self: next time pack Hazel a bone.
She didn’t even look apologetic or guilty! Oh well…fishing line is pretty cheap to replace and I’m sure she assumed it was a chew toy I had placed there for her.
All in all, it was a very successful activation. In less than one hour, I put 22 stations in the log. The weather was perfect and the whole family had a blast.
A photo I took prior to watching a reenactment of the Battle of King’s Mountain.
What a wonderful day to play radio, take in our national parks and re-live some of our history!
I should be on the air starting sometime between 20:00-20:30 UTC (4:00 – 4:30 PM EDT). I’ll plan to operate SSB on two frequencies: 14286 and 7286 kHz. I’ll be on the air for one hour or so, if all goes well. Listen for my amateur radio call sign: K4SWL.
If you hear me on the air, please consider submitting a spot to the DX clusters!
It just doesn’t seem possible that I have almost everything I need to make the NPOTA activation today in this pittle pack.
I am planning to activate the Carl Sandburg Home (NS07) for National Parks on the Air today. I should start sometime between UPDATE (17:00-18:00) UTC and operating for about one hour. I’ll be SSB/QRP on 14286 and possibly 7286 kHz (depending on the type of antenna I can deploy). I’m fitting this activation into a busy day, but will do my best to hit the air and work as many stations as possible.
I just finished packing everything for the activation.
This will be the first time taking my Elecraft KX2 to the field. It feels *very* strange not to pack even an external battery. Just the little radio, an antenna, a clipboard, an assortment of adapters and a short run of coax.
Not sure yet if I’ll hang the Par EFT trail-friendly antenna or use my telescoping fiberglass vertical (which performed admirably last week!). This is a sensitive archeological site, so I have to abide by the wishes of the park ranger on duty (though I’ve been given permission to install the vertical near their vegetable garden). I want to hang the EFT so I’ll have two bands (20 and 40) at my disposal.
If you have the time today, please try to work my station!
After two months in Canada, I’m pleased to make some time this weekend to activate PK01, the Blue Ridge Parkway.
I’ll be joined by my good friend, Vlado (N3CZ), and we plan to set up at the Folk Art Center on the parkway around 11:00 EDT and be on the air by 11:30 EDT (15:30 UTC).
TROTWOOD, Ohio (WDTN) – The iconic venue brought sports, concerts, entertainment and special interest shows to the Miami Valley for 60 years is closing their doors due to not being able to overcome an internal legal battle that has spanned the last two decades.
“We are painfully aware of the loss this announcement will generate, which is why we have fought so long and hard to prevent it,” says Karen Wampler, Hara’s marketing director.
The loss will come in the form of $36 million in annual economic impact; youth, men’s and professional hockey programs; and the hundreds of events that called Hara home this past year.
“We had hoped to announce a new era at Hara, but are announcing the end of one, instead.” says Wampler. [Continue reading…]
The Dayton Amateur Radio Association (DARA) regrets to inform our many vendors, visitors and stakeholders that, unfortunately, HARA has announced the closing of their facility. We have begun execution of our contingency plan to move Hamvention® 2017 to a new home.
DARA and Hamvention® have enjoyed many successful years working together with HARA Arena and we wish the Wampler family the best.
DARA and Hamvention® have been working on a contingency plan in the event HARA would become unavailable. We have spent many hours over the last few years evaluating possible locations and have found one in the area we believe will be a great new home! Due to logistics and timing issues, we will make a formal announcement introducing our new partner. This information will be coming soon. We all believe this new venue will be a spectacular place to hold our beloved event. Please rest assured we will have the event on the same weekend and, since it will be in the region, the current accommodations and outside events already planned for Hamvention® 2017 should not be affected.
We look forward to your continued support as we move to a new future with The Dayton Hamvention®.

Challenges for a new venue
Two years ago, I spoke with a DARA representative who told me about some of the contingency sites they had in mind should HARA Arena close its doors. Many of us attending the Hamvention had a strong feeling 2016 would be the last year at HARA Arena.
Though HARA was (and has been) in a poor state, the site is very large and has one very unique feature: it’s all on one level.
The outdoor exhibits (flea market) portion of the Hamvention is very popular.
Most of the Dayton area contingency sites were on at least two levels with limited elevator facilities (a potential problem for the hundreds of attendees who use motorized carts).
I also learned that most of the Dayton area contingency sites had another problem: not enough space to have both the inside exhibits and the flea market hosted at the same venue. One contingency plan assumed the flea market might be relocated somewhere else nearby.
I hope the Site B will have the space for both the indoor and outdoor exhibits. Frankly, if these two portions of the Hamvention are separated, I suspect it will have a very negative impact on attendance numbers. Let’s hope this won’t be the case.
In terms of facilities, almost anything else will feel more modern and cleaner than HARA Arena. I just hope it can accommodate 20,000+ attendees as well.
When DARA announces the new site, I will post the information here. Simply follow the tag: Hamvention.
I am loving the new QRP Ranger power pack–it is the solution I decided on after publishing this post a few weeks ago. It’s a little pricey, but it’s built like a tank, very lightweight, includes a charge controller made specifically for the LiFePo cells, and made here in the USA. It also had a very readable LED display that my buddy Eric says is, “reminiscent of the displays on the Apollo 11 module.” He’s kind of right!
It’s so nice to have both a volmeter and ammeter on the front panel.
We just finished activating the Hopewell Culture National Historical Park (I’m writing this post while Eric drives us to our next activation). I made 12 contacts running SSB at 8 watts. Eric made 16 contacts via CW at 5 watts.
We have planned two more activations this afternoon:
Charles Young Buffalo Soldiers National Monument at 16:30 UTC
Dayton Aviation Herital National Historical Park at 21:00 UTC
I’ll be calling CQ on 14.290 MHz and 7.290 MHz +/-.
Please hop on the air listen and/or answer my call if you’re a ham!
On my way this morning to FDIM and the 2016 Dayton Hamvention.
