When my wife and I made the difficult decision to move back to the US in 2003, we had a wide variety of options of where to live. There was no doubt in our minds, though, that we would end up settling down somewhere in the Asheville, NC area.
We’re both from western North Carolina and had both–at different times–lived or worked in Asheville. It’s a beautiful area with a good arts scene and loads of outdoor activities.
These days, as I’m involved with both Parks On The Air and Summits On The Air, it’s an especially appealing place to live. We’ve a number of accessible POTA/WWFF entities and loads of summits to activate.
Blue Ridge Parkway (K-3378)
Any time I drive into Asheville, I pass by the Blue Ridge Parkway.
There are a number of easy parkway access points on the north, east, south and west sides of Asheville. I typically pass by the eastern access point of the BRP on Tunnel Road. Both the Blue Ridge Parkway Headquarters and the Folk Art Center are within spitting distance and both have picnic tables making setup and deployment quite easy for POTA/WWFF ops!
On Monday, November 29th, 2021, I found that I had a good 30-45 minutes to kill before heading home after running errands in town. My car was empty, as I was hoping our collision shop would ask me to finally bring the Subaru in for repair. They were waiting for one critical component to arrive.
Side note: Bears in cars
As I mentioned in a previous post, in late October, a bear opened all four doors of our car and proceeded to check inside for food. He wasn’t exactly “surgical” in his investigation and was likely frustrated when he realized there was no food to be found inside (never store food in your car in bear country).
So when George (KJ6VU) asked if I would be interested in talking about backpacks and gear bags as a guest on the Ham Radio Workbench podcast, I agreed without hesitation.
What I love about the HRWB podcast are all of the truly deep-dives into a wide variety of topics. Quite often, topics are well outside my particular interest area, but the more I listen, the more I’m drawn in. The hosts’ enthusiasm is infectious.
It was an honor to join this fine team for a few hours of workbench projects, ham radio, and pack geekery.
If you’ve never listened to the HRWB podcast, I’d encourage you to check it out and subscribe. I think you’ll agree that the hosts–George, Mark, Mike, Rod, and Vince–have an amazing chemistry.
Thanks again, guys, for inviting me on the show. As I said after the recording, it was great “being on the other side of the lawnmower.”
On Sunday, November 28, 2021, my family needed a little time outdoors after a Saturday full of home projects.
I packed my field radio kit in the GoRuck Bullet Ruck, then we jumped in the car and drove to the Clear Creek Access of South Mountains State Park (the same site in my previous POTA field report).
South Mountains State Park (K-2753)
It was a gorgeous day and we had the park to ourselves. First thing we did was hike the short Lakeview Trail loop.
This trail is only 1.3 miles long, but offers up some beautiful views.
Hazel also came along and enjoyed the sights, smells, and even got her feet wet in a stream!
Fortunately, no one was using the one solitary picnic table at the Clear Creek access, so we claimed it!
First thing I did was launch a line and deploy my 28.5′ speaker wire antenna.
I knew it would pair perfectly with the Elecraft KX2!
I love this compact Weaver throw line bag!
The new N6ARA TinyPaddle
This activation also gave me an excuse to check out a paddle my buddy Ara (N6ARA) recently designed.
He calls it the TinyPaddle:
An appropriate name, because this key is wee! Ara notes:
As someone who likes bring experimental gear to summits, I have had paddles break on me multiple times. […] I don’t like carrying the extra weight/volume of a second set of paddles, so I designed my own “TinyPaddle” for backup as a middle ground option. It weighs roughly 3.7g and is 1.2cm x 1.2cm x 5.0cm in size.
He’s right, the TinyPaddle could tuck away even in the most compact of field kits. You’d never know it was there.
Here’s the TinyPaddle connected to the side of my Elecraft KX2:
Ara sent this key to me for frank feedback (prior to doing a small production run of them) knowing I’d not only check it out in the shack, but (of course!) take it to the field.
I decided to do my activation at South Mountains State Park using only the TinyPaddle.
Before taking it to the field, I had some concerns that the TinyPaddle might turn in the 3.5mm key port on the side of the KX2 as I used it. Once plugging it in, though, I could tell that it would not be a problem at all. The paddle is so lightweight and so sensitive, it’s simply not an issue. In fact, it would be rather difficult to use it in such a way that it would shift in the 3.5mm port.
On The Air
Knowing in advance that it was a contest weekend (the CQWW), I decided I would stick with the WARC bands during this activation.
I tuned the speaker wire antenna to 10.112 MHz on the 30 meter band.
Hazel asks, “Got any doggy treats in that pack, daddy?”
The 30 meter band was more crowded than usual as many other POTA/SOTA/WWFF and casual operators sought refuge from the signal density on 40 and 20 meters.
Since I had the family with me and since we’d spent most of our time at the park eating a late picnic lunch and doing a casual hike, I allotted only 20 minutes of air time for this activation. I was hoping I could validate the activation with 10 contacts in that amount of time.
I started calling CQ with the N6ARA paddles. First thing I noticed was how sensitive and precise they were. Although the TinyPaddle is a mechanical paddle (with spaced contacts), they feel more like a capacitive touch paddle they’re so sensitive.
I started calling CQ POTA and soon logged KE4Q.
A few minutes later, I worked AI8Z, followed by W5WIL, WO0S, WA2JMG, AA0Z, WA2FBN, N0VRP, KA3OMQ, W9SAU, and K1MZM.
With a total of 12 stations logged in 21 minutes, I went QRT.
QSO Map
Here’s what 5 watts into a 28.5′ speaker wire did on 30 meters that fine day (click map to enlarge):
Video
Here’s a video of my full activation. Hazel was being very camera shy; for some reason, she doesn’t like the OSMO Action camera. My wife and I think it must resemble something she’s seen at the vet’s office? We may never know!
Ara is obviously a talented engineer. I’m always impressed with devices like this that are so simple, yet so effective.
The TinyPaddle is going to live in my KX2 field pack as a backup to the KXPD2 paddles which have actually failed me in the field before.
That time the KXPD2 failed me…
I mention in the video that I once needed to use my Elecraft KXPD2 paddles to communicate with my buddy Mike (K8RAT) to share my SSB frequency for a very rare park activation I activated in the spring of 2020. After plugging the KXPD2 paddles into the KX2, I found that I could only send “dits.” I couldn’t even set it up to send as a straight key from one side of the paddle.
This forced me to drive 25 minutes to a spot where I had cell phone reception to contact Mike with info for a spot, then drive back to the site. That effectively shortened my activation of this ATNO park by 50 minutes!
KXPD2 missing one of the two center posts.
I sent Elecraft the photo above and they quickly identified the problem: turns out, one of the center posts had loosened and fallen out. They immediately sent me a replacement post free of charge (typical Elecraft customer service).
I use the KXPD2 paddles quite a lot because they mount directly to the front of the KX2 making it possible to use my kneeboard during SOTA activations. Since that mishap in the field, I tighten the KXPD2 posts at least once a month and also carry a precision screwdriver with me in my field kit.
A proper backup!
But having the TinyPaddle now is even extra insurance that a paddle failure won’t stop me from completing my activation!
When I made the video, I wasn’t certain if Ara was planning to do a production run of these or not. I’m very pleased to see that he has!
I’m certain he could actually fetch much more for these paddles, but he wants them to be an affordable, accessible backup paddle for anyone doing CW field activations.
He even includes a link to his Thingiverse page where you can download and 3D print accessories (including a TinyPaddle holder) and replacement parts at home free of charge.
Ara, thanks for making your project so available and accessible to everyone!
I hope you enjoyed this field report and activation.
I’d like to send a special thanks to those of you who are supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free–I really appreciate the support.
Thank you!
73,
Thomas (K4SWL)
Bonus photos!
My daughter Geneva (K4TLI) took a few extra photos at the park that day. Enjoy!
She took this candid photo of me as I packed up the KX2. Check out my KSKO (McGrath, AK) tee shirt! Thanks for that, Paul Walker!
I mentioned in a previous post that I recently purchased a Ten-Tec Argonaut V transceiver. It was–being honest here–an impulse purchase. This is what I get for randomly browsing the QTH.com classifieds!
Truth be told, I’ve always loved the design of the Argonaut V and I knew, being a Ten-Tec, it would be a proper CW machine.
As soon as I received the Argonaut V, I put it on the air and chased a few parks and summits from the shack. It seemed to work brilliantly, but of course I was eager to take it to the field!
Around the same time, my buddy Max (WG4Z) mentioned that he’d discovered a new access point for South Mountains State Park and had enjoyed performing an activation there. He wrote,
“It is a part of South Mountains State Park custom made for a Thomas Witherspoon visit. A great site for an activation, video, and photos. If you haven’t been there, please put it on your list!“
So I just finished putting together a dedicated, compact field kit for the QCX-Mini. I’m planning to do a SOTA activation tomorrow, if the stars align. Hopefully, they’ll align!
One of the newest products in this kit is my high viz 2mm x 50M Marlow throw line. I learned about this throw line from Mike (W4MAF)–thank you, Mike! It is much less bulky than standard poly throw line and fits in my Tom Bihn small travel tray. We’ll see how well it works tomorrow. First impressions from having used it at the QTH once was very positive.
Again, with any luck I’ll have this kit in the field tomorrow on a summit. If you’ve nothing better to do, look for me on the SOTA Watch spots page!
If you’ve been reading QRPer.com for long, you’ll know that there’s no cure for my pack addiction, so in a sense, there could be no better gift!
Spec-Ops Brand
I’ve been a long-time customer of Texas-based Spec-Ops Brand.
I first discovered their gear at the Wright Patterson AFB Air Force base Military Clothing Store with my buddy Eric (WD8RIF) in 2013. I purchased their Pack-Rat pouch and reviewed it on the SWLing Post.
The Pack-Rat PouchPack-Rat Interior Organization
Since then I’ve purchased numerous products from Spec-Ops Brand.
I’ve owned the Spec-Ops T.H.E. Pack Tactical backpack since 2013 as well. You don’t see that pack in my field reports because, frankly, it’s just too big for most of my field radio applications. It’s designed for armed forces deployments and has a lot of capacity. I primarily use it for camping and extended travels.
Spec-Ops introduced an EDC (Everyday Carry) version of the T.H.E. Pack Tactical in 2015 or after so many customers asked for it. The EDC version is identical to the larger T.H.E. pack in every respect, just smaller in every dimension.
Looking good
It’s very early days, but I suspect this pack will become my choice Summits On The Air (SOTA) pack.
In terms of size/capacity, it’s ideal for summit day hikes and the thing is just covered in Molle (Modular Lightweight Load-Carrying Equipment) straps, so very adaptable if I need to attach extendable masts, hiking poles, water bottles, or basically a Molle pouch or accessory.
If you’re interested in the new Xiegu X6100 QRP transceiver, I’d strongly encourage you to check out Josh’s latest view on the Ham Radio Crash Course YouTube channel:
I’m very pleased to see that Xiegu has addressed some of the issues found in their pre-production model. Most encourgaing!
I look forward to checking out the X6100 soon and putting it through the paces in the field. Although I say this with some apprehension, the X6100 does look promising.
I know that Scott (KN3A) will have his X6100 soon and also will share his thoughts and field experience. [Update] Scott comments with some unfortunate news:
“Sadly, I received mine on Monday morning, and I had to return it to HRO last evening. Intermittent problems with transmit/receive on all bands except 40 meters. Did a couple of videos to document the issues before returning it last night. Hopefully it was just a fluke and there will be a replacement. There are a lot of things I liked about the radio in the short time I used it on Monday. It certainly does have potential.“]
It was pouring rain, but I had a respectable three hour window to fit in a park activation while visiting my parents in the foothills of the NC mountains.
I had such an enjoyable experience pairing my Elecraft KX2 and AX1 antenna under a shelter at Tuttle Educational State Forest during a previous rainy day activation, I decided to revisit the same site.
Tuttle Educational State Forest (K-4861)
I knew I would likely be the only visitor at Tuttle that day; it was pretty cold and very wet.
Knowing rangers might not expect visitors on a day like this (keeping in mind this type of park caters to educational groups and are otherwise relatively quiet) I made a courtesy call to the park headquarters. I asked the ranger for permission to use their main shelter for an activation.
I hope your readers in the UK can give me some pointers I’m looking to assemble a very small portable solar set-up something I can easily move between multiple locations that isn’t too heavy to travel with.
I’ve had a look around on a few forums, eBay and Amazon but haven’t got a clue what I need. Fast charge speed isn’t a critical factor for me as long as I can get some charge into my batteries on a sunny day.
I know I need a foldable panel, solar controller and maybe cables to hook up to the battery but with a million options out there I don’t know where to start but I think panels between 60/120W output would give me enough power.
I would be most grateful if your readers particularly in the UK could give me some pointers.
My 12V 12Ah battery uses F2 spade terminals and the 30Ah uses M5 ring terminals but I have no issues using crocodile clips to make the connection.
Thank you.
Anas Patel
Thank you for your question, Anas.
While I know what is needed in theory (a PV panel, a good charge controller, cables, and a battery), I don’t know the charge controller market that well. As with batteries, I assume product availability may vary greatly by region.
I typically pair my IC-705 with a 3 to 6 aH Bioenno LiFEPo battery pack.
I do know this: it’s important that your charge controller is rated for the battery chemistry you have/adopt. In other words, if you’re using LiFePo4 batteries, make sure the charge controller is rated for LiFePo4.
Another thing to keep in mind is that many solar panels are terminated with industry-specific connectors like the MC4. Sometimes you can integrate those connectors into your system, other times you may prefer terminating them with other connectors.
My hope is that readers might chime in with the components they successfully use in their portable charing systems. Please comment!
This is timely because I’m actually plotting a portable PV system for my field kit and will be taking notes. I can’t decide if I should simply piece together a system around existing components I have (I would need to connect a couple small folding panels in parallel a get a LiFePo4 controller) or if I should simply go for an all-in-one system like the PowerFilm Solar Lightsaver Max.
A couple days ago I finally took delivery of the uSDX/uSDR transceiver I ordered in late October from this seller on eBay. I’ve been tinkering with it in the shack since then and have started to form some initial impressions.
The uSDX is a super cheap transceiver and, to be clear, my expectations were (spoiler: thankfully) very low.
If you’ve been here for long, you’ll know that I don’t normally test or review super cheap transceiver varieties found on eBay, AliExpress, etc. So many people asked me to check out the uSDX, however, that I decided I would try to give it a shake out.
I’ve yet to take this little radio to the field, but I have made a couple dozen contacts from the shack, all in CW and I’ve done a lot of listening. Yesterday afternoon, I even hooked it up to an oscilloscope.
It’s still early days and I’m sharing the following observations and notes with the hope that uSDX owners might be able to guide me if I need to make menu adjustments to sort out a few issues.
More specifically, there are two big cons with my uSDX:
Con #1: The Audio
Trying to be diplomatic and kind with my words here, but let’s just say the uSDX audio leaves much to be desired.
I think it’s great this little transceiver has a built-in top-mounted speaker, but it produces some of the harshest, most spluttery audio I’ve ever heard in a radio.
On top of this, the volume control (which requires going into an embedded menu item to adjust) is just…strange. It’s hard to explain, but the audio feedback isn’t what I would expect from a volume control or AF gain. It seems like each volume control step (starting at “-1” and going up to “+16”) is a mix of both AF and RF gain values. It doesn’t have a fluid amplification progression like I would normally expect.
In fact, I can’t really turn the volume up to +16 because on many bands around level +14 or +15, it starts to emit a really loud squeal.
Although very minor compared with the issues above, the audio amplification chain also has an ever-present hiss.
In addition, even with the volume turned to “-1” I can still hear splattering and even garbled whispers of CW signals if connected to an antenna.
I hope I’m missing something here and the audio can be tailored for better listening. Perhaps there’s a combination of adjustments I can make in the menu options to help?
Please comment if you own a uSDX and can provide some feedback.
Con #2: The Receiver
Again, unless there’s a magic combination of adjustments I can make in menu items, I find the receiver of the uSDX to be incredibly anemic.
I took the uSDX to my buddy Vlado (N3CZ) yesterday and we hooked it up to an analog oscilloscope and signal generator.
We concluded that the uSDX is very sensitive, but the front end seems to be as wide open as a barn door.
This confirmed my on-the-air observations made over the past two days: even with the 500 Hz DSP filter engaged, CW signals as far away as +1.7 kHz could easily bleed through. In fact, quite often when I tune to a POTA or SOTA station operating CW, I could even hear FT8/FT4 stations bleeding through from far across the band.
I couldn’t help but think if I had taken the uSDX on my recent Mt Mitchell SOTA activation instead of the QRP Labs QCX-Mini, there’s no possible way I could have handled the pileup. The uSDX receiver would have completely fallen apart because it shows no ability to handle tightly spaced signals.
Again, if you’re a uSDX owner and can provide some insight here, I would very much appreciate it.
Still testing the uSDX TX
One of my main goals with purchasing the uSDX was to test the transmit signal to see how clean it might be and if there were spurs in any harmonics.
Vlado hooked up the uSDX to his oscilloscope and we discovered that it did produce spurious emissions in harmonics of the 40M band. The spurs were negligible and we both assume it might possibly be within FCC guidelines.
With that said, Vlado didn’t completely trust this particular analog oscilloscope because there appeared to be a slight fault in its BNC input port. We ran enough tests–and even compared the uSDX to my KX2–to know that there are definitely faint spurious emissions and that the CW transmit signal isn’t nearly as clean as the KX2.
Here’s a 2 second video clip showing the uSDX transmitting CW on 7 MHz into the scope:
I plan to hook the uSDX to a digital oscilloscope to get more accurate results in the near future.
Not all cons
The uSDX does have some positive attributes.
For example, the QSK is quiet and even full break-in. This little radio is also chock-full of features. I’ve even found that though it’s advertised as an 8 band radio, mine will transmit on 10 bands; everything from 160-10 meters.
I think if I planned to operate the uSDX on SSB when the bands were relatively quiet, it might do quite well for casual contacts.
Time will tell…
To be clear, though, the issues above can be deal-killers for me.
I want my transmitted signal to be clean enough to at least meet FCC requirements–I like being a good neighbor on the bands. This might require some modifications on the output, but let’s see what a digital oscilloscope might reveal.
Of course, if the uSDX can’t handle multiple CW signals being thrown at me at once, I can’t see how this would possibly work as a SOTA or POTA field radio.
I can already tell that the ergonomics of the particular uSDX model I purchased will likely lead to–as Spock put it in Star Trek IV–some “colorful metaphors.” Especially when I reach for the volume control buried behind a menu item. (I mean, seriously?)
Again, if you own a similar uSDX, I’d love to hear your comments and suggestions!
