30 Meters with a 4 Foot Whip–? Impromptu POTA Hunting with the Elecraft KH1!

10 Comments
My Elecraft KH1 packed in a Pelican Micro M40 case. This protects my KH1 while traveling around in my EDC backpack.

On Friday, December 8, 2023, playing POTA was not in the plan.

I needed to finish a field report, publish it, then attempt to make a dent in my email and comments backlog. Lately–as you might have noticed–it’s been difficult to keep up with everything.

That morning, I dropped off my daughter at her robotics class, then made my way to the Mills River Library and municipal park.

I arrived at the park around 9:20 AM, parked my car at one of the free EV charging spots, then walked to the library front door only to discover a sign that said they’d be opening an hour late (10:00).

All of the sudden, I had 40 minutes to kill.

Since my Elecraft KH1 now lives in my EDC backpack full-time, I thought, “Why not hunt a little POTA?”

I started walking to the baseball field to set up then turned around, went back to the car, and grabbed my action camera. I mean…why not film this session since the camera was in the car trunk/boot? Right–? Right!

POTA Hunting!

Keep in mind that the Elecraft KH1 is designed to operate on 20, 17, and 15 meters using the 4 foot whip antenna (assuming you have the internal ATU option).

This was awfully early in the morning for any of those bands–I knew 20 meters would be my best bet of the three.

I tuned around, but I couldn’t hear or work any of the handful of activators on 20 meters. They were all outside my 20M propagation footprint–most were simply too close for 20M.

Then I noticed my buddy, John (AE5X) spotted on the 30 meter band.

For kicks, I tuned down to the 30 meter band, found a clear spot, then hit the ATU button. I was surprised to achieve a 2:1 match!

What?

Of course, a decent impedance match doesn’t equate to efficiency. Then again, what did I have to lose? Nothing…that’s what!

I called John once, but another strong station caught his attention. Once he finished that exchange, I called him again and he replied! Woo hoo!

I suspect my effective power output was around 1-2 watts, but it was enough to make an exchange with John, so I was a very happy camper.

I also tried to work KD8IE on 30 meters, but could not punch through the strong signals from other POTA hunters.

By chance, though, I heard my buddy Eric (WD8RIF) calling CQ POTA just below KD8IE.  I could hear Eric because I had my filter wide open–as in SSB wide.

I tuned  down, called him and he came back with my call and a question mark after two tries.

We exchanged details, sent 72, and logged each other. What fun!

I found out later that my signal level was actually fine on Eric’s end, but I was *almost* outside of his CW filter edges. He struggled hearing me because I was too far from his centered frequency. I didn’t notice this on my end, of course, because I had my filter so wide open.

I’ve learned from this: next time I’ll narrow my filter before hunting stations. The majority of activators do not run with their filters wide open like I do.

30M on the KH1 whip!

I’m pretty sure Elecraft wouldn’t recommend using your KH1 on 30 meters with the whip only because of its low efficiency, but I also know the KH1 will have no problem dealing with the 2:1 match. I bet you’d get an even better match if you lengthen the counterpoise–I simply used the supplied 13′ wire.

Of course–and again–30M on a 4′ whip is not an efficient antenna system, but it’s efficient enough to make some contacts! As my buddy Kurt (NT0Z) says, “RF gotta’ go somewhere.”

I will check in with N6KR and see what he says about this setup.

Library time

Post activation, I found a comfy spot to work in the library and published a new field report.

It struck me that no one passing by would have ever guessed that I had a full HF station in my backpack! For just a moment, it made me feel like an unassuming Cold War spy!

Oh yeah, the backpack: I took advantage of a Black Friday sale at Trakke and purchased the Bannoch Backpack I’d been eyeing for weeks–the discount was deep!

I justified this purchase knowing that I was doing my bit to support the economy of Scotland! Ha ha! Seriously, though, I do love this backpack.

Thank you!

Ham Radio Workbenches On The Air (& POTA): A short field report and a very long activation video!

3 Comments

Many of you know I’m on the crew of the Ham Radio Workbench podcast. In fact, as of this month, I’ve been there a year now (my how time flies).  Although it shows a certain lack of judgement on their part, I’m glad they invited me on board!

On October 9, fellow HRWB crew member, Mark (N6MTS), pitched an idea to us via email:

“What do y’all think about doing an HRWB On The Air event?”

We all agreed it sounded like a great idea. Things like this normally take a year’s worth of planning, promoting, and organizing. Not when Mark’s in charge, though.

Next thing we know, Mark had us sorting out the best date/time (December 3, 2023/1800-22:00UTC) for HRWBOTA and even reached out to some amazing volunteers who helped put together a website and spotting page.

Holy cow!

December 3, 2023

I planned to operate the entire four hour event period from Lake James State Park (K-2730) since it would be an easy detour en route to Hickory, NC (where I was staying that night). Of course, each contact would could for both HRWBOTA and POTA.

The previous day, however, I learned that one of my daughters had a meeting in downtown Asheville from 18:00-19:00 UTC. She doesn’t have a driver’s license yet, so I had to take her. Had it not been an important meeting in advance of her finals, she would have skipped.

This really threw a wrench in the works. I knew that by the time her meeting ended and I dropped her off at the QTH, the earliest I could be at Lake James was 20:15-20:30 or so.

How could I increase my on-the-air HRWBOTA time?

KH1 to the rescue!

Since the Elecraft KH1 was packed in my EDC bag, I decided to play a little HRWBOTA in the parking lot behind the meeting building.

I wasn’t sure what to expect to be honest. I wasn’t spotting myself anywhere but the HRWBOTA spotting page, and I was limited to the 15, 17, and 20M bands with the KH1’s 4′ whip antenna.

I spotted myself, hit the air and started calling CQ HRWBOTA!

In the span of about 45 minutes, I managed to log a total of 15 stations! Not bad considering I was standing in an urban parking lot, swimming in QRM, and going QRP!

I didn’t make a video of this part of the HRWBOTA activation–sorry about that if you worked me then. I needed every moment of on-the-air time I could grab. Here’s my log sheet:

Lake James State Park (K-2739)

I legged it to Lake James after my daughter’s meeting–in fact, to save time, I started my activation video while I was still in my car driving on I-40.

I arrived at Lake James, parked, plugged in the car, grabbed my gear and made my way to the picnic area next to the lakeshore. It wasn’t hard to find a site with a tree that might support my KM4CFT 30/40M linked EFHW antenna.

I include the full antenna deployment and station set-up in my (rather long) activation video below. Continue reading Ham Radio Workbenches On The Air (& POTA): A short field report and a very long activation video! →

SSB and CW QRP POTA: Testing my new KM4CFT End-Fed Antenna Kit!

12 Comments

A few weeks ago, I mentioned that Jonathan (KM4CFT) sent me one of his new QRP end-fed half-wave/random wire antenna kits.

When my friend, Alan (W2AEW), caught wind that I planned to buy some 26AWG wire for this build, he sent me a spool of wire from a large reel he’d recently picked up at a hamfest.

What a nice guy! The blue wire is absolutely ideal for portable antennas.

Being the nice guy he is, Alan actually published a video about building Jonathan’s antenna kit on his YouTube channel. I highly recommend watching it!

Before I received the kit, I already knew what type of antenna I’d build: a 30 meter end-fed half-wave (EFHW) linked with a 40 meter extension. This antenna design has been on my mind for some time and Jonathan’s kit was the perfect excuse to build one.

Why a 30M EFHW with a 40M extension? Because a 40M EFHW gives me excellent SWR matches on 40, 20, 15, and 10 meters without needing an ATU.  A 30M EFHW gives me matches 30 and 17 meters.

Thus, with one linked wire antenna, I can cover 40, 30, 20, 17, 15, and 10 meters! That’s a lot of bands!

And since the antenna needs no extra matching, it’ll work with my transceivers that lack an internal ATU.

The Mountain Topper MTR-5B I acquired earlier this year.

In fact, I originally thought about this antenna design to use with my Mountain Topper MTR-5B which covers 40, 30, 20, 17, and 15 meters.

I built this antenna by first trimming it for a 1:1 match on 30 meters including a loop and strain relief to attach the extension.

When I was satisfied with my 30M EFHW, I then made the 40M extension, attached it to the 30M section with 2mm bullet banana connectors, then trimmed the antenna for a 1:1 match on 40M.

I spent the better part of 60 minutes trimming this antenna. I feel like patience really pays off because it’ll set up the antenna for good matches on all of the upper harmonics. Admittedly, I was a bit pressed for time that day, so I only tested this antenna in one configuration (an inverted vee shape) so hadn’t checked the SWR as a sloper or vertical.

My advice is to aim for a 1.3:1 or better match on 30M and 40M–that should be very doable if you wound your transformer correctly.

This was my first attempt at making in-line links, so I wouldn’t consider link my method as a “best practice”–rather, check out K7ULM’s guidance for making in-line links. Continue reading SSB and CW QRP POTA: Testing my new KM4CFT End-Fed Antenna Kit! →

POTA by Bicycle: VA3MZD’s QRP Ham Radio Journey

Many thanks to Rod (VA3MZD) who shares the following guest post:

POTA by Bicycle: A Ham Radio Journey

By Rod Murray VA3MZD

First, some background: I earned my Canadian Basic With Honours Amateur Radio License in February of 2022 as a retirement goal while taking advantage of pandemic isolation time to read and study for the exam. I then chose VA3MZD as my call sign. Back in 2007, while teaching in Australia, my students gave me the Aussie nickname, Mr Muzzdog, and it stuck. I’m now Victor Alpha Three Mike Zulu Delta.

At about the time I got licensed, I acquired a Yaesu FT-818ND QRP radio. I had read and heard a lot about POTA and was eager to get on the air but also to operate outdoors. Being active in hiking, cycling and paddling, my immediate goal was to activate a local park on one of my outdoor adventures. I learned as much as I could about QRP and POTA from subscribing to Thomas’ QRPer Blog as well as numerous other channels. I was thrilled when I made my first HF QSO followed shortly thereafter with my first POTA contact as a Hunter from my QTH. This made me even more intent on activating a Park.

My activation attempts from a local park, however, were unsuccessful. QRP with a compromised, mini loop antenna wasn’t working for me. My first successful activation was unique and did not occur until a few months later, far from home.

In May 2022 I traveled to Vancouver, BC to visit family. One of the regulars on my radio club’s morning net (The Elmira Radio Club), a long distance Elmer, so to speak, offered to take me to a local British Columbia park and help me make my first activation. Despite having never met, Trevor VE7BM, scheduled a rendezvous east of Vancouver at VE-3304, Castle Park, and in half an hour, we had over 10 QSOs in the log. I was hooked!

My First Activation with Elmer VE7BM at VE-3304, Castle Park, BC

Upon returning to my home province of Ontario, I acquired an EFRW antenna that I eventually tested for the first time on Field Day in June of 2022. The Nelson 9:1 worked well with my FT-818 and I began taking it on visits to my local Conservation Parks and on hiking trips. I made several successful activations with it but I then ordered a much more portable Tufteln QRP EFRW that Thomas had demonstrated on his QRPer channel. It performed very well and became my regular POTA antenna after installing the Nelson 9:1 permanently in the attic.

Having four POTA units close to home, all within 10 km, made it very convenient to make trips by vehicle to activate them. What makes those 4 parks even more interesting from an outdoor activity perspective is that they are linked by a well maintained rail trail, The Elora-Cataract Trailway which just happens to be part of VE-5082, The Great Trail of Canada! The rail trail connection means that all of these parks can be easily accessed on foot or, my preference, by bicycle.

The Elora Cataract Trailway / The Great Trail of Canada VE-5082 near Shands Dam and Belwood Lake

I started taking my pared down kit, the radio, antenna, tuner, battery and throw line in my bicycle pannier on my regular rides. Then I’d set up the radio for a POTA Activation while visiting a park. My most frequented and my most favourite is VE-5319, Belwood Lake Conservation Area, because of the 10 km eastbound ride through farms and forests, over Shands Dam into the park. Not only is it a pleasant ride, it’s a 2-fer with The Great Trail!

POTA by Bicycle at Belwood Lake Conservation Area – VE-5319/VE-5082

In the westbound direction, The Trailway ends in the scenic and historic tourist town of Elora, and just beyond the town is The Elora Gorge Conservation Area, VE-1392, where the Canadian Heritage designated Grand River cuts a 22 metre chasm through the limestone bedrock.

It has serviced campsites, trails, picnic shelters and tables near mature White Pine trees (Ontario’s Provincial Tree) perfect for deploying a wire antenna. I’ve been fortunate to have met each of these Parks’ Superintendents, and have been able to promote Amateur Radio, my radio club, and also received their full support for POTA activations and Winter Field Day.

Between the two historic mill towns of Fergus and Elora that make up the municipality of Centre Wellington and accessible from The Trailway, stands The Wellington County House of Industry and Refuge National Historic Site, VE-5928. Now renovated to serve as the Wellington County Museum and Archives, the historic limestone building has an interesting, well documented history.

Greg discovers the joy of QRP in his first QRP SSB POTA activation

12 Comments

Many thanks to Greg (KJ6ER) who shares a post he originally published on Facebook regarding his first ever QRP SSB POTA activation. This post is just as much a break down of his field kit, so we’re also including it in our Field Radio Kit Gallery.

My First POTA QRP SSB Activation

by Greg (KJ6ER)

Wooo hooo! After 700 QRO SSB POTA activations in California over the past 2 years, I decided to try my first 10-watt QRP SSB activation from K-3473 in San Jose. To my pleasant surprise, it was very successful: 121 SSB QSOs in 4 bands (10, 12, 15 and 17M) across 5 countries including DX to Japan, Alaska and Argentina. I worked 34 U.S. states and 5 Canadian provinces. I operated a total of 4 hours, averaging a QRP QSO every 2 minutes. Lesson learned: Inspired by my QRP mentor Kevin Behn, QRP is not only as fun as QRO (when the bands are working) but it is simpler and faster to deploy. And I can wear the entire station on my back!

My QRP shack-in-a-pack is the ICOM IC-705 (in an ICOM backpack) with a 7M Spiderbeam fiberglass telescoping pole and my homebrew resonant halfwave monoband antennas. Quite frankly, a significant contributor to my success was the monoband resonant halfwave antenna: low angle of radiation and more gain than a typical quarterwave with radials. I modeled this after my homebrew POTA Dominator resonant halfwave antenna. If you’re interested in more detailed information about this antenna and components in my backpack, take a look at each photo with descriptions (below).

Starting on 10M, I was planning to work my way down the HF bands to 20M where I assumed would get me the most QSOs and help me officially activate.

Well … I never made it to 20M: by band, 24 QSOs on 10M, 13 QSOs on 12M, 32 QSOs on 15M and 52 QSOs on 17M = 121 QSOs! I will plan to do a 20 and 40M QRP activation soon, as well as 2M and 70cm since the IC-705 supports those bands, too.

Many thanks to all the hunters who helped me complete my first QRP activation! While I certainly did not experience any massive pile-ups like my typical QRO activations, the slower pace QRP activation made it very relaxing. I strongly recommend it! Feel free to let me know if you have any questions, I’d be happy to help  72 KJ6ER, San Jose

Field Kit Details

My complete QRP shack-in-a-pack!

The ICOM IC-705 running 10 watts off a 3Ah Bioenno battery. Just to the right of the pack in the field is my 7M Spiderbeam fiberglass telescoping pole supporting monoband resonant halfwave wire antennas for 10M, 12M and 15M. I also use the pole to operate on 17M and 20M as a sloper or inverted-V, and 40M as an inverted-V. I love how fast I can get operating with just a backpack and telescoping pole!

My first QRP SSB 10-watt activation resulted in 121 QSOs on 10-17M including DX to Japan, Alaska and Argentina.

I thought I would need 20M to activate but the uppers bands worked so well, I never got there. I completed my activation in 4 hours and averaged about 1 QRP QSO every 2 minutes. While I was not getting my usual 5-9 QRO signal reports, I was heard clearly on the low noise upper bands with my QRP SSB signal.

The 7M Spiderbeam fiberglass telescoping pole supports my monoband halfwave vertical wire antennas for 10M, 12M and 15M, as well as 17M and 20M when used as a sloper or inverted-V. I also use it as a center mast for my 40M inverted-V. Continue reading Greg discovers the joy of QRP in his first QRP SSB POTA activation →

Getting To Know You: The Yaesu FT-817/818 Series Portable QRP Transceivers

13 Comments

I’m very fortunate in that in the past few years I’ve acquired a number of QRP radios that I use in rotation when I do park and summit activations.

I’m often asked for advice on choosing radios, and as I’ve mentioned in the past, I feel like the decision is a very personal one–everything is based on an operator’s own particular preferences.

I’ve written formal reviews about most of the field radios in my collection. In those reviews, I try to take a wide angle view of a radio–to see how it might appeal to a number of types of operators. I highlight the pros and cons, but I don’t focus on my own particular take because, again, my style of operating might not match that of readers. I try to present the full picture as clearly as I can and let the reader decide.

The Getting To Know You series gives me an opportunity to highlight one radio at a time and showcase what I love about it and why it’s a part of my permanent radio collection. After we spend a bit of time talking about the radio, we’ll do a park or summit activation with it!

The Yaesu FT-817 and FT-818 Series

As I mention in my “Getting To Know You” video below, my very first dedicated QRP field radio was the original Yaesu FT-817 (non-ND version), so it has a special place in my heart.

At the time, I was living in the UK and travelling extensively throughout Europe with my UK call (M0CYI).

The FT-817 hit the market and it blew my mind. Up to that point, there were no general coverage QRP radios on the market that small, that comprehensive, and that even sported VHF/UHF multi-mode coverage. It even had a small internal battery pack! What?!

I was an early adopter of this radio and travelled with it extensively–indeed, in all of the years I lived in the UK and Europe, the FT-817 was my only amateur radio transceiver.

Fast-forward to 2023–some 23 years later–and I still have an 817. Actually, I have two 817ND’s and one 818ND (although, I plan to sell one of my 817NDs soon–I don’t need three!).

I find the 817/818 to be an incredibly robust and capable field radio. It’s also a brilliant value–few radios offer you the capabilities of the FT-817/818 for under $700.

My FT-817ND in an Armoloq TPA-817 Frame.

Yaesu discontinued the FT-818ND almost exactly one year ago. Retailers no longer have new stock, but there are loads of them on the used market. Keep in mind that the FT-817/818 was a cash cow for Yaesu for over two decades–the used price remains fair because there’s just so much supply out there. I routinely see 817ND and 818ND models selling for between $375-700 depending on how they’re configured and what’s included.

If you’re looking for a comprehensive article about the Yaesu FT-817/818 series, I would encourage you to check out this piece I originally wrote for The Spectrum Monitor magazine.

Learning from the best – a perfect SOTA morning with K6EL

San Francisco Radio Diary – Part 2

by Leo (DL2COM)

I can’t remember if I have ever walked through a eucalyptus forest before but I am pretty sure I have not as I would have instantly remembered the intense and pleasant smell.

eucalyptus trees
High eucalyptus trees on the north side of Mount Davidson (W6/NC-423)

The morning sunlight and a few scattered low clouds created a rather mystical atmosphere as I was hiking up a narrow and slippery trail on the north-east side of Mt. Davidson in Central San Francisco (W6/NC-423).

sun, fog and trees
This here? Yes please.

My research regarding the trail system of this compact urban mountain was barely existent so I did not end up using the south entrance (Landsdale Ave. & Dalewood Way) which would have taken me to the summit in only a few minutes on a dry and tidy path – but then sans the nice forest panorama. Not worth the tradeoff I’d say.

Mount Davidson Cross

Due to its proximity to the city center, Mt. Davidson is as easily accessible as pretty much anything in SF for visitors who don’t want to travel further than say a 30 min bus/Uber ride or so. Activators will be rewarded with stunning views of the bay area and the city’s skyline as well as a majestic cross, apparently a well-known SF landmark.

The big plateau on the summit of Mount Davidson

I had contacted Elliott (K6EL) prior to my trip to the U.S. who according to the SOTA database has been on Mt. Davidson many times (and on many other summits as I only learned later). This morning I got up early, texted him and was very happy that he agreed to join me spontaneously for my first U.S. activation. Elliott arrived only a few minutes after me as I was struggling to tie a rope to a stone slightly squinting from jetlag. Neither did I bring a throw weight nor a mast due to cabin luggage restrictions. I now know why I cherish these things so much but Elliott assured me that we’d get that wire up eventually and we started to chat.

It turned out that Elliott has done a lot of work for the SOTA and ham radio community. For example, as part of the SOTA management team and being a super active activator (only scratching the surface here): e.g. no.4 Honor Roll Summit-2-Summit (S2S) world-wide pushing almost 10k S2S QSOs. Wait what? That’s a hell of a lot of mountain-top radio experience, so his reassuring words instilled a high degree of confidence for my improvised antenna setup. Not only did we manage to get the 31’ random wire up in a high tree but he also brought a 2m HT which I had (I admit) forgotten in Germany.

While I was still busy setting up the station he had already bagged a handful of FM S2S QSOs. That’s how it’s done.

31′ random wire to 1:9 unun & 17′ counterpoise in a sorta inv. v-to-l’ish-shape

Suddenly two police officers showed up on motorcycles and I started gathering a number of arguments in my head as to why our activation is a completely legitimate thing (strange reflex or comprehensible?). They approached us in a very kind way and after we greeted each other Elliott pointed to our wire antenna and let them know that “We are ham radio operators and this will be our antenna for the next hour.” Full stop. Ha.

In fact the two officers didn’t need any arguments from us, instead they showed genuine technical interest and at some point we were all joking around together. I believe they were just happy to find everything in good order and maybe also catch a few warming sun rays. Still I loved the way Elliott presented our activity as the most natural and non-optional thing. I guess I just didn’t know how local police would react at first. A good reminder that mutual respect goes a long way.

By now the fog had cleared and blue skies showed all around. I was itching to get on the air! To break the ice I logged a quick S2S contact with WD4CFN on Max Patch, a mountain on the NC/Tennessee border. Off to a great start! Elliott suggested starting on 10m so that’s what I did.

CQ SOTA DE W6/DL2COM K…uff I needed a few attempts to get that W6/ prefix into a somewhat natural CW flow but then first contacts started rolling in.

F4WBN, Chris, with a strong signal from France. So cool to hear him on the other side of the planet as well. He was shortly followed by LW2DO from Argentina and then a bunch of US operators including four more S2S QSOs before S57S (Slovenia) and JG0AWE (Japan) topped off the log with a warm DX rain. WOW!

Today’s QSO Map

I could have called CQ forever but decided to call it a day after 27 QSOs and rather enjoy the sun, view and good company. After all, I also needed to get back to the city in time.

Elliott kindly offered to give me a ride so we had some time to discuss – how could we not – the KH1, current DXpeditions, and various topics around SOTA, U.S. ham radio and the city of San Francisco.

Steve tests the Diamond RHM-8B during a SOTA activation

Testing the Diamond RHM-8B portable screwdriver antenna

By Steve (MW0SAW)

I have seen many amazing K4SWL SPOTA pileups on YouTube using the AX1 antenna and the extension coil. I have fancied trying a small walkie talkie style whip antenna for a while now.

I have a AX1 and KX2, but my Yaesu FT-818 was the radio with a fully charged battery. So I pulled out The Diamond RHM-8B, an antenna I purchased a while ago but never used in the field. It has a BNC fitting and you tune the antenna by sliding the coil up and down for loudest signal and best SWR. They make one very chunky walkie talkie together! Diamond products do have a fantastic air of quality about their construction.

Radio conditions weren’t great, and bands were busy being the weekend of the CQ WW CW contest. So decided to go the my nearest summit that’s amount 12mins in the car and about a 25mins hike up. This was GW/SW-034 Garth Hill. On a clear day you can see out over the Bristol Channel into England, but mist/fog were the order of the day.

I wore the FT-818 and rubber duckie around my neck with the neck strap for a couple of 2m FM contacts, before setting up on 40m SSB sitting on the ground. Without a tablet or chair with me I found it most comfortable to support the radio between my knees.

I was really pleased to get 9 QSOs in the log, some 59 reports, some difficult contacts. Moving on to CW I managed another 8 QSOs with an S2S into Germany.

All the QSOs were UK and mainland Europe, but I was more than happy with the haul for such a small antenna.

So conclusion about the Diamond QRP antenna.

Can you qualify a SOTA summit on a short 1.5m whip antenna? Absolutely, no sweat!

Does it work as well as a full size wire antenna? Of course not. Nowhere close.

However, its makes such a great rapid deploy, ultra packable option with the Yaesu. Not quite as small as a AX1 but you have the bonus of not requiring a tuner. Definitely something for a travel bag if you own a FT-817/818.

Sunday, October 15, 2023, was the final day of the W4 SOTA campout. That morning, Joshua (N5FY) and I packed up our tents/gear then played a little radio at our campsite (at Lake Rabun). We weren’t in a hurry because the morning was so enjoyable. In fact, I think we checked out not a minute before the dealine of 12:00 noon!

We both decided we wanted to squeeze in one more radio excursion before driving back to our QTHs.

Tallulah Gorge State Park (K-2202)

It wasn’t realistic to fit in another SOTA hike due to our schedules, but Tallulah Gorge SP was an easy detour for both of us.

We pulled into the park and queued up to to enter. The park was absolutely teeming with visitors that day. I would have expected nothing less on such a gorgeous Fall afternoon!

Joshua and I found a quiet picnic area–with a few picnic tables spaced apart from each other–near the lake shore. It turned out to be a perfect spot to play radio. We spaced our sites far enough apart so as not to easily interfere with each other while on different bands.

Joshua set up his KX1, a wire antenna, and used VK3IL pressure paddles.

Joshua deployed his KX1 next to the lake and I deployed my KX2 a bit further up the hill.

I paired my KX2 with my “no transformer” random wire antenna. Of course, I used a Tufteln antenna because, I mean, N5FY was standing right there! ?

This antenna consists of two 28.5′ 26AWG wires connected directly to a male BNC. Simplicity itself on the antenna side. It’s the KX2 internal ATU that does all of the matching (since there’s no transformer). I find that the KX2 can match this antenna from 40-10 meters with ease.

I think the magic of these simple random wire antennas is that they’re directly connected to the radio. There’s a bit of efficiency in having no line losses, etc. even if the ATU does soak up a bit of energy.

Connecticut POTA/SOTA combined activation

By: Conrad Trautmann, N2YCH

November 24, 2023

The author, Conrad, N2YCH at POTA K-1717, Sleeping Giant State Park & SOTA Mt. Carmel, W1/HH-002

Looking for my next activation challenge, I wondered if there were any overlapping POTA parks with SOTA summits in the state of Connecticut. I’ve only done two SOTA activations to date, one in Maine and the other in New Hampshire. I thought, there must be a few in Connecticut.

On my home computer, I brought up both the POTA map and the SOTA mapping page and quickly realized that it would take too much time to try and compare the two maps. Instead, both sites offer KML exports, so I exported all of the Connecticut parks from the POTA site and the summits from the SOTA mapping page and imported both files into Google Earth Pro. A yellow push pin represented the POTA locations and a blue triangle the SOTA locations. It was easy to spot the overlapping sites. Mt. Carmel and Talcott Mountain are both POTA parks and Summits for SOTA. There are a few other SOTA sites that have POTA trails that cross over as well.

I decided to tackle Mt. Carmel, SOTA W1/HH-002 also POTA K-1717, Sleeping Giant State Park. I’d already activated Sleeping Giant for POTA before, but not from the summit. For a SOTA activation to count, the operator must be within the “Activation Zone” as defined by the SOTA rules.

The Connecticut state web site has good maps and information about the park and showed that the trail to get to the summit is an “easy” 1.6 mile hike. I thought that sounded like a reasonable distance. What they don’t tell you on the web site that it’s also a 600’ climb up in elevation from the trailhead to the summit. I knew it would require a climb, but I didn’t expect that. I made the trip up, but it was challenging, especially carrying my backpack with the radio, a VHF handheld, antenna, batteries, computer, water, etc. I plan to travel lighter the next time.

The Mt. Carmel trailhead

Before I get to the activation, a little about the park. It’s called Sleeping Giant because from a distance, the ridge looks like a person laying on their back.

From the CT DEEP site

It’s located in a mountain range called Hanging Hills which extends North from Long Island Sound through Connecticut and Massachusetts up to the Vermont border. Quinnipiac University is across from the entrance to the park and the Quinnipiac Indian Tribe once inhabited the area. Please indulge me as I also share the ghost story of “The Legend of the Black Dog of the Hanging Hills.”

“If a man shall meet the Black Dog once it shall be for joy; and if twice, it shall be for sorrow; and the third time he shall die.”

As the legend has it, the Hanging Hills area is haunted by the Black Dog. You don’t want him to cross your path three times. It’s this story that is the basis for the SOTA “Master of the Black Dog” certificate. “An activator must have entered valid activation logs from each and every summit in the Hanging Hills Region and must have survived all of the activations.” There are currently four summits in the Hanging Hills Region. I need this award.

So far, I have completed activating one of the four summits and did NOT see the black dog. Wish me luck on the remaining three.

The view about half way up
The Lookout Tower

The lookout tower at the summit is the main attraction of the park. Built in 1936, it is listed on the National Register of Historic Places. It stands four stories tall and is 739’ above sea level, providing a 360 degree view in all directions and a clear view over New Haven to Long Island sound. According to the Sleeping Giant Park Association, over 100,000 people visit it each year.

I’ll admit, after hiking the trail up, the last thing I wanted to do was climb four stories more. I did go up before I left to get some photos.

For the activation, I found a bench to set up on with space behind me to set up the Chelegance MC-750 antenna. I ran FT8 on 20 meters beginning around 10 am ET and after roughly 30 minutes, moved up to 10 meters. My experience running QRP on digital modes is that I will cover the Eastern half of the US and some Europe on 20 meters. I can usually make contacts out to the West Coast and into Europe on 10 meters especially later in the day. By activating on both frequencies, I tried to cover as much area as I could to provide the best opportunity for hunters and chasers to reach me.

Setup: MC-750 vertical antenna in grass behind bench and KX3 and computer on bench

Equipment List

Coverage from the summit: Yellow pins are 20 meters, Green pins are 10 meters

Looking at the map, you can see that I covered the Eastern portion of the US on 20 meters. It was also 10 am local time and still pretty early on the West coast. When I shortened up the antenna and retuned the KX3 for 10 meters, I started making contacts with Germany, Italy and other EU stations.

The hike down from the summit was much easier, the temperature had warmed up a bit and I stuffed my coat into the backpack for the trip down. When I got to my Jeep, I noticed a number of empty picnic tables nearby and decided to set up and get a few more POTA contacts while I was there. I ended up with 48 total for the day.

The summit I was at was an easy one (worth 1 point) compared to many and it was challenging to me. I came away from the experience with a new appreciation for the challenges SOTA activators face. I also came away with a new goal, to get the Master of the Black Dog certificate!
