POTA Field Report: Activating South Mountains with the new N6ARA TinyPaddle!

12 Comments

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.

Gear:

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.

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!

And the TinyPaddle?

In short? I love the TinyPaddle!

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!

He’s made a storefront on his website N6ARA.com and is now selling the TinyPaddle as a kit for $15 or fully assembled for $20 US.

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!

Click here to check out the TinyPaddle at N6ARA.com. Note that he’s doing these production runs in batches, but you can pre-order them.

Thank you!

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,

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!

Field Report: Let’s play POTA with the Ten-Tec Argonaut V!

12 Comments

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!“

On Wednesday, November 10, 2021, I packed my Argonaut V and headed to the South Mountains State Park Clear Creek Access. Continue reading Field Report: Let’s play POTA with the Ten-Tec Argonaut V! →

QRP & Tea: Pairing the Elecraft KX2 & AX1 under shelter at Tuttle Educational State Forest

14 Comments

Sometimes field activations can be relaxed and laid-back. Other times they can be absolute mayhem!

Having explored the whole mayhem style activation the previous day, I was seeking a more chilled-out field activation on Thursday, November 4, 2021.

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.

As expected, he said, “It’s all yours!” Continue reading QRP & Tea: Pairing the Elecraft KX2 & AX1 under shelter at Tuttle Educational State Forest →

FT8 Portable: Steve takes his Phaser Digital Mode Transceiver to the field!

8 Comments

Many thanks to Steve Allen (KZ4TN) who shares the following guest post:

FT8 QRP Portable

I recently finished my Phaser digital mode QRP transceiver kit and have had a hankerin’ to take it portable, and today was the day.

Temps were in the upper 60s with clear blue sky. About fifteen minutes from home is the Watauga Point Recreation Area on Watauga Lake in Carter County, Tennessee. It’s a day use area and is not an official POTA site, though it is in the Cherokee National Forest, which is. I opted to not make this a POTA activation as it was more of a first time “proof of concept” trip.

The Phaser is a small digital mode transceiver designed by Dave Benson, K1SWL with the enclosure the design of AA0ZZ, Craig Johnson. Phasers were available for most all of the HF bands, put out between 3 to 5 watts, and in addition to FT8, have the ability to program a second frequency to operation other digital modes such as PSK-31. They were sold and supported through Midnight Design Solutions, but unfortunately are no longer being offered. Occasionally I see them coming up for sale on the QRZ.com swapmeet forum.

In addition to the Phaser, I brought an FT-891, an LDG Z-11Pro 2 tuner, a netbook computer, and two batteries; a small AGM for the Phaser and a deep cycle lead acid power pack for the FT-891. I brought my W2LI magnetic loop antenna and a homebrew “NorCal Doublet” that sets up as an inverted V on a 20 ft kite pole as a backup antenna. The whole kit (excluding the batteries) fits in two wooden ammunition crates which make it really easy to drive, set up, and operate.

One note on using the W2LI mag loop. You need to first tune the antenna using the radio and listen for an increase in the background noise level. Using the Phaser while connected to my computer made that not possible. If I had brought a small set of earphones I could have plugged them into the audio out jack on the Phaser and tuned for max background noise. So, instead I connected FT-891 to the loop and used it to tune the antenna to 30 meters. Next time bring earphones.

After about fifteen minutes I had the station set up. The waterfall on WJST-X showed that the Phaser was receiving transmissions but no displayed text. Unfortunately I had neglected to synchronize the computer clock before I left the house. The netbook is pretty old and the internal battery needs to be replaced. What to do? First I tried to manually sync the clock to WWV but Windows 10 won’t let you set the seconds in the clock to 00. As I had cell service I figured I could use my cell phone as a hotspot. Never having set it up before I have to say that it was pretty easy. Thank you 21st century tech! This allowed me to sync the internal netbook clock, but it also let me log contacts on QRZ.com, and check my propagation on PSK Reporter.

The Phaser puts out around 3.5 watts, so I didn’t respond to a CQ that was less than -5 dB. While PSK Reporter showed reception of my signal up and down the East coast, contacts were scarce. I seemed to have a window open up into New England as I worked PA, MA, and CT. I was right in the middle of my fifth contact when the computer battery died so that was it. WSJT-X reported these stations on the +dB side for reception but my signal strength was always reported at < -10 dB.

The 30 Meter band was up and down with band conditions being reported as only Fair on the Solar-Terrestrial Data report on QRZ, and at one point for about a half hour there were no signals displayed on the waterfall.

With a loop antenna on a tripod and 3.5 watts I can’t complain. I’m thinking of building an RF amplifier to boost the output up to 10 watts which should help. My next step is to load WSJT-X on my tablet and see how portable of a kit I can assemble. As FT8 was designed as a weak signal mode, it’s perfect for QRP portable operating.

SOTA Report: New QCX-Mini, new Packtenna EFHW, and pileup insanity on Mount Mitchell

18 Comments

Do you know what it’s like when you have a new radio and you can’t wait to take it to the field?

Yeah, me too!

Even before I received my QCX-Mini in October 2021, I already knew where I’d take this pocket-sized, single-band QRP CW transceiver for its first field activation: Mount Mitchell (W4C/CM-001).

Mitchell is the highest summit east of the Mississippi river and only about 6 miles from my QTH as the crow flies.  I had yet to activate Mitchell this year for SOTA although I have activated it for POTA/WWFF several times. As I’ve probably mentioned in the past, Mount Mitchell park is my “happy place.” Our family loves this site and we visit it frequently to hike in the spruce-fir forest.

On the morning of Wednesday, November 3, 2021, I realized I had enough room in my schedule to swing by Mount Mitchell for an activation, so I quickly assembled my SOTA pack around the QCX-Mini. Continue reading SOTA Report: New QCX-Mini, new Packtenna EFHW, and pileup insanity on Mount Mitchell →

Putting the KM4ACK End-Fed Half-Wave on the air at Table Rock!

9 Comments

Lately, I’ve been in the mood to build kits.

I say “lately” but in truth I’m always tinkering with something in the shack.

The radio room/office at my QTH is pretty small, though, and I don’t have a dedicated, full-time workbench. I’ve been mentally re-arranging the room and trying to sort out a way to make space for one because it would be so nice to have a spot where my soldering iron could remain hooked up at all times.

For the moment, when I work on kits I use our dining room table so I try to stick with one or two session kits as opposed to the multi-day variety.

KM4ACK EFHW

KM4ACK Image

A number of readers and subscribers have asked me to check out the KM4ACK 49:1 End-Fed Half-Wave antenna kit.  This kit is produced by Jason (KM4ACK) and purchasing his kits supports his excellent YouTube channel.

I have a lot of field antennas, so I don’t really need another EFHW, but then again I like having a dedicated resonant wire antenna with each of my radios and, (hey hey!) it’s a great excuse to build a kit!

KM4ACK Image

I purchased the KM4ACK kit and received it within a week. Building the antenna was incredibly straight-forward. Jason packaged the components in small bags so finding parts was easy. I really appreciate kits that aren’t one large “bag-o-parts.” Continue reading Putting the KM4ACK End-Fed Half-Wave on the air at Table Rock! →

40M Activation: Pairing the Icom IC-705 and CHA LEFS at Tuttle Educational State Forest

14 Comments

I’ve gotten a few messages from readers lately asking, “Why no love for the Icom IC-705?”

Looking back, I realize that I haven’t had the ‘705 in the field for quite some time (at least, in a video and field report).

Truth is, the ‘705 has been doing duty as a shortwave listening receiver in shack and just hasn’t hopped into my field pack recently. Since it’s important for the health of all field radios to soak in the outdoors on a regular basis, I packed it in my bag and took it to one of my favorite parks.

Tuttle Educational State Forest (K-4861)

The weather was beautiful on Thursday, October 21, 2021.

When I arrived at Tuttle, the first thing I did was hike their 2 mile loop to get the blood pumping.


This also gave me time to decide on the antenna to deploy: my Chameleon CHA LEFS.

The CHA LEFS sloper

The CHA LEFS has served me quite well in the past, especially on days with mediocre propagation.

During my hike I decided to do the entire activation on 40 meters only, just to get a better idea how the CHA LEFS’ propagation footprint might look with a larger sample size.

Gear:

On the Air

This was also the first time I’d used my N0SA paddles with the IC-705. Isn’t it cute?

Setup was quite easy.

I deployed the CHA LEFS with the feed point at about 35-40′ into a large tree.

The radiator sloped down to a point in the middle of a field and the end was elevated perhaps 4′ off the ground. I secured the end of the antenna to a length of paracord, the end of which was attached to a heavy stick on the ground, stretching the radiator.

The CHA LEFS is resonant on 40 meters, so no external ATU was necessary.

I hopped on the air, started calling CQ POTA in CW and within 10 minutes was rewarded with 10 contacts. It doesn’t get much better than this for a good start!

I continued calling CQ and, in the end, worked a total of 22 contacts in 30 minutes–almost all in CW. Check out the video below to see how it all played out.

Many thanks to KC5F and N9UNX for the Park-To-Park contacts!

Here’s my real-time, real-life video of the entire activation (less antenna set up and take-down):

QSO Map

The QSO Map shows an interesting pattern: a ring with a few close regional stations (almost NVIS), and an outer ring of 40 meter skywave:

Thank you!

I believe one of the attractions of activating parks and summits is the fact that we really have no idea in advance how it might all play out. It’s a bit like going fishing.

I’ve gotten a lot of questions from readers lately about what propagation tools I use. In truth, my main propagation forecasting tool is my buddy Mike (K8RAT). Before I head out–or if he knows I’m hitting the field–he’ll usually text me current conditions and they’re quite accurate.

At the end of the day, though, propagation forecasts never stop me from doing an activation when I want to play radio. I just go out there and see what happens. As I’m sure my childhood fishing buddy–my Great Uncle Luther–would have said, “Any day fishing is better than a good day at work!” (Of course, a real quote from Uncle Luther would have included more “colorful metaphors.”)

POTA Field Report: Coffee & QRP at Tuttle Educational State Forest

28 Comments

Thursday, October 28, 2021 was a wet, rainy day but I wanted to do a POTA activation on the way back to the QTH after having visited my parents for a couple nights.

I didn’t have a lot of radio gear with me on that trip, but I had the right gear: my Elecraft KX2 transceiver and AX1 antenna. If I could activate a park under a covered picnic shelter, I knew I would stay dry while playing radio.

There are only two parks within a reasonable detour that have covered picnic shelters: Lake James State Park and Tuttle Educational State Forest.

Lake James was the shortest detour, but they tend to be busier than Tuttle and last time I was there? Yeah, the picnic shelter was occupied.

On the other hand, I was nearly certain that I would have the picnic shelter all to myself at Tuttle. It would be a slightly longer detour, but worth it. Continue reading POTA Field Report: Coffee & QRP at Tuttle Educational State Forest →

Pairing the KX2 & Speaker Wire Antenna at Johns River State Game Land

4 Comments

You might have noticed that normally I’m a good 2-4 weeks behind posting activation videos and field reports. This is due to the fact that I typically record an activation video one week, upload it sometime within the following two weeks, then write up the field report, add photos, and put it all together when the stars align.

Much of my workflow is dictated by the fact that it can (literally) take 2-3 days for a video to upload from my rural QTH. Therefore, I never upload from home, only when I have proper bandwidth.

However, I’m happy to announce that this field report and video are going to move to the front of the line! Continue reading Pairing the KX2 & Speaker Wire Antenna at Johns River State Game Land →

POTA Field Report: Pairing the Elecraft KX2 with a stolen doublet at Table Rock Fish Hatchery!

4 Comments

Someone asked me recently which activity I prefer more: Summits on the Air (SOTA) or Parks On The Air (POTA)?

Truth is, I like both.

I like SOTA because I love hiking and playing radio on the summits of some pretty impressive mountains.  I’m often treated to amazing views and the DX can be spectacular. I love the sense of accomplishment when the activation goes well and I’m back home later feeling a bit tired from a long hike. Good stuff!

I like POTA because it’s incredibly accessible (thus fits in my tight schedule easily). Many of the parks have great hiking trails, and there’s almost always a picnic table available making set up so much easier.  Here in western North Carolina it’s almost a given that park picnic tables are surrounded by large trees and have a reasonable amount of space, thus POTA sites can be ideal for antenna experimentation.

I don’t typically experiment with antennas during SOTA because after hiking 2-3 hours to a summit, I feel pretty invested in the activation and the last thing I want to do is roll the dice with my antenna.  With POTA, I can bring a few extra supplies or “plan B” antennas if something goes sideways.  Plus, unlike parks, summits are often lacking in tall trees so I stick with shorter wire antennas and self-supporting verticals.

On the morning of October 20, 2021, I decided that I wanted to try a new antenna or an antenna I hadn’t used in quite some time. My intention was to dig out my Wolf River Coils TIA vertical, but when I reached into my antenna bag, I pulled out a nondescript Shure microphone pouch. I scratched my head for a moment…

For the life of me, I couldn’t remember what this was, so I opened it up and discovered a doublet inside! Not just any doublet, either–based on the use of a 35mm film canister in the antenna’s construction, I knew it had to be a creation of my buddy Eric (WD8RIF).

Then my memory kicked in. Continue reading POTA Field Report: Pairing the Elecraft KX2 with a stolen doublet at Table Rock Fish Hatchery! →
