Brian Activates Allegheny National Forest and Remembers a Dear Friend

Many thanks to Brian (K3ES) who shares the following guest post:

Activation at Allegheny National Forest:  Remembering a Friend

by Brian (K3ES)

The last few weeks have been rough for the K3ES household.  In past activation reports, I introduced you to our two Boston Terriers.  Molly and Jojo came to us as rescue dogs in October 2022, and we have worked hard to help them feel safe and loved.  Unfortunately, both came to us with unexpected health problems.  We were able to get Molly through treatment for heartworm, and she is thriving.  Jojo always had something holding her back, but we were never quite sure what.  We lost her just before Christmas, and that was a real punch in the gut.

Jojo was a special dog.  When we brought her home, she barely weighed 15 pounds.  Even after we managed to build her weight up to 25 pounds, she was still thin for her frame.  She also came to us hunched, cowering, and emotionally traumatized.  It took months for her to start coming out of her shell.  We got glimpses of her as a feisty, and loving dog, who took real joy from laying in the sunshine.  We were hopeful that she would one day come into her own, and give our jubilant Molly a real run for her money.  Sadly, it was not to be.  She had increasing problems with mobility.  We treated her for a bone infection, for possible tick-borne disease, and for joint inflammation.  Steroids and pain medication helped her quality of life a lot.  It was only near the end that the likely culprit was identified as cancer, but even expensive diagnostic tests failed to confirm that.  Finally, her body just crashed, and we had to let her go…

Jojo supervises a truck activation of Allegheny National Forest in March 2023.

Looking back through pictures of Jojo, I discovered some that were taken during a never-reported “truck activation” of Allegheny National Forest (K-0619) back in March, 2023.

I have never thought that my vehicle-based activations were terribly interesting, so I never spent the time to report them.  Suddenly, that particular activation held new meaning, because one of the few times I got Jojo out with me for a POTA activation happened because I was doing a low-impact drive-up, working from the truck.  She rode shotgun, and sat happily in the passenger seat while I made contacts.  Molly sat in the back seat, napping from time to time.  After the radio gear was packed away, the three of us even managed to take a short trail walk along a Forest Service Road that starts at the parking area.

Jojo and Molly lead the way on the Forest Service Road after the radio gear was packed away.

Last week, I found myself in serious need of radio-therapy.  Since Molly is always ready to go for a ride and a POTA, I decided to take her along to re-create the prior activation that we did with Jojo.  So this is the story of our salute to a departed friend, a tribute activation, as it were.

Activation

Molly and I packed her blanket, picked up my KX2 field kit, and jumped in the truck for a 20 minute drive to the trail-head parking area that we had activated with Jojo last March.  It has trees, a decent driving and walking surface that would not be too muddy from recent rain, and the Forest Service road where we had walked after the previous activation.  This time, Molly rode in the passenger seat, alternating between napping, and looking at the scenery as we drove.  Upon arrival she stayed put, while I used a throw line to put up my Tufteln 35 ft EFRW as a sloper.  I hooked the unun around my 2 meter mobile antenna, and ran coax into the truck through the lower part of the driver-side door seal.  I set up the KX2 on the center console/armrest, prepared my log, and got on the air to start the activation.

Tufteln 9:1 unun was clipped to my 2m mobile antenna, with the 35 ft radiator sloping up to a tree, the 17 ft counterpoise dropping down to the ground, and the RG316 feedline leading into the truck.

Results

As with almost all of my activations, I ran this one entirely CW QRP.  Beginning just after 1900z (2 pm local), I decided to start on 15m and work my way down the bands.  The HF bands were in good shape, and 15m netted 2 quick contacts, then 17m yielded 6 more.  The pace picked up when I moved to 20m (12 contacts in 22 minutes), and got even faster on 30m (17 contacts in 19 minutes, before it was time to call QRT).  While I was on the air, Molly did some supervising and some super snoozing.

Molly is an interested supervisor…
But supervising is tiring work.

Working steadily for an hour and a quarter, and finishing with 37 contacts was just the kind of break that I needed.  I want to sincerely thank the hunters who made this activation a success.  For just a short while, I was focused on CW, call signs, and signal reports, and the sense of loss receded a bit from my consciousness.

Molly and I walked along the Forest Service Road.  We felt incomplete…

Conclusion

After I packed up the station, Molly and I repeated our walk along the Forest Service road.  With just the two of us, it was definitely a bittersweet experience.  I think Molly felt our loss, too.  I like to think that Jojo would have been fine with missing this activation.  The weather, while not raining, was cool, overcast, and a bit gloomy.  The sunshine that she treasured was absent for us that day.  Hopefully, she has found a place in perpetual sunshine, and is soaking up the rays.  Good bye sweet pup.

We will always remember Jojo in her natural element, bathing in sunshine…

Hold on tight to those you love, and do something special with your four-footed companions.  I wish you all the best in 2024.

Chris activates Les Iles Nature Reserve with his Plessey PRC-320!

Many thanks to Christian (IX1CKN) who shares the following field report:

Activation of I-0395

by Chris (IX1CKN)

Hey folks, I just wanted to share my activation at the Les Iles Nature Reserve (I-0395) on Christmas Eve (December 24, 2023)!

It’s been a while since I last visited (in July). The weather was perfect, around 20 degrees Celsius, and I was in the mood for a real outdoor activation.

I decided to go with the manpack Plessey PRC-320, a trusty companion delivering a solid 25 watts. I wanted to be one with nature, so no benches or bird-watching huts this time.

Got off to an exciting start on 20 meters with two stations from the UK recognizing my gear. One even complimented the excellent modulation with a whopping 9+10 signal strength, giving me hope for the rest of the activation. Then came a Spanish station, the always attentive IX1VKK Rinaldo (following me from home), a colleague from the Netherlands, another Brit, and then… silence. I kept calling for another 5 minutes, but no luck.

Could it be the morning flare that affected propagation? Who knows, but I noticed on the POTA cluster that another Italian colleague was activating on 28 MHz and being spotted by several American Hams. I decided to give it a try, found a clear frequency locally, and started calling. And guess what? Responses from across the Atlantic started pouring in – Massachusetts, Georgia, and even a park-to-park with Jim KC1QDZ from Brenton Point State Park in Rhode Island.

Short video:

Maybe not my first contact with a U.S. park on 10 meters, but definitely a memorable one.

Signal reports weren’t super strong, hovering around 5/3-5/4, but hey, as long as the noise floor isn’t sky-high, that signal is enough to complete the QSO. Moved to a different frequency as the band was buzzing with North American stations – Kentucky, New Jersey, North Carolina, and Maryland.

An hour in, and I’ve logged 12 contacts. Pretty incredible considering that what “saved” my activation were stations on the other side of the ocean. Europe on 20 meters was a bit challenging, but hey, that’s ham radio for you. You’d think POTA, with its simple and not-so-full-power setups, is a local affair, and then, on Christmas Eve, you realize DX is very much on the table.

I turn around, a duck dives in, and the last rays of sunlight caress the wetlands. Perfect way to end it.

Keying In The Rain: One rather soggy but incredibly fun POTA activation!

9 Comments

I’m lucky enough to live in a part of the world where–by and large–the weather is pretty darn nice.

In fact, I recently received a comment from a reader who jokingly said that I should work for the tourism board of western North Carolina because the weather always seems so pleasant in my POTA/SOTA videos.

It’s true: most of the time I hit the field to play radio, the weather is very pleasant.

That said, you see more of these “fair weather” activations because I tend not to make videos of ones in poor conditions mainly because I don’t like managing the camera in high winds, heavy rains, or even super cold conditions–especially when I want to get in and out of the field quickly. The camera tends slows everything down.

On Friday, December 1, 2023, though, I decided to do a park activation in the rain and make a video! Here’s my field report:

Pisgah National Forest (K-4510)

That Friday morning, I dropped my daughters off at classes, then made my way to the Mills River library to put the finishing touches on a field report and publish it. It was rainy and I wasn’t complaining; it had been a very dry fall in WNC up to that point.

After I published my field report and attempted to catch up on the email backlog a bit, I hopped in the car and headed to the Sycamore Flats picnic area in Pisgah National Forest (K-4510) and Pisgah Game Lands (K-6937).

That day, knowing it would be soggy, I packed my Discovery TX-500 which is pretty much rain-proof. By this, I mean that it’s designed to cope with rain, but it’s not designed to be completely submerged in water.

Truth be told, I had no intention of making an activation video. Once I arrived on site, though, I thought, “Why the heck not?” After all, other than being rainy and chilly, conditions were pretty pleasant. That and my OSMO action camera is completely waterproof.

I grabbed the camera and started filming the activation while closing up the car.

Setting Up

When playing POTA in the rain, I tend to select picnic tables or sites that are under the canopy of trees if at all possible. Trees not only provide antenna supports, but they also help divert a bit of the rain.

I found an ideal site under the canopy of a few hemlocks.

I deployed my PackTenna end-fed half-wave (EFHW) oriented (nearly) vertically and with the feed point close to the tree trunk so that it would be better protected from the rain. I wasn’t worried about the antenna getting wet, but I also didn’t want the toroid and windings to get completely soaked either. It’s never a bad idea to use what bit of natural protection the trees can offer.

As you can see in the photo above, I had my TX-500 completely exposed, but the battery, in-line fuse, and (to some extent) the speaker mic were all protected in the TX-500’s Telesin Case.

As always, I used my Rite In The Rain notepad which is a champ at handling wet conditions. Continue reading Keying In The Rain: One rather soggy but incredibly fun POTA activation! →

Field Report: Alan’s P2P POTA Activation Challenge!

13 Comments

Many thanks to Alan (W2AEW) who shares the following guest post:

A self-imposed POTA Park-to-Park Challenge…

by Alan (W2AEW)

One of the things I love about the Parks on the Air program is that every activation is a bit of small challenge.  What will the band be like?  What antenna will I be able to deploy when I get there?  Will I have a spot to setup?  Will my CW ‘ear’ be properly tuned up? You get the picture…

There are a few parks that I activate much more than others – call them my “home” parks.  These are the ones that are close to my home, easy to get to and setup.  One in particular,  Washington Rock State Park (K-1635), is certainly the closest. It has some interesting Revolutionary War History.

Not only is this park very close to my home, it also has pretty good elevation (about 500’) for this part of New Jersey.  In fact, the local fire department hangs a very large illuminated star during the Christmas season at their building that is adjacent to this park.

This star can be seen for miles to the South and East of the ridge.

It’s no wonder that I’ve activated this park more than 20 times in the last year and half.

My XYL Nancy was *very* generous to me this year at Christmas – gifting me a new Begali Adventure CW paddle!  She even had it engraved with my call:

I wanted to think of a unique way to celebrate my first POTA activation using this paddle. I would be going to K-1635, so the location would be very familiar.  Therefore, I thought of an interesting self-imposed challenge…   Attempt to complete an activation with ONLY Park to Park contacts!

As I thought about this, I figured my best chance of success would be to operate on the weekend (significantly more parks are active), and use my most efficient multi-band antenna (a 40m EFHW).

Being an engineer, I’m use to having goals.  I’m also used to having additional constraints imposed – let’s call them stretch-goals.  Possible stretch goals for this P2P Activation Challenge could be:

  • Operate QRP (all of my POTA activations are QRP, so not much of a stretch)
  • Operate only CW (nearly all of my activations are CW, and this helps with the QRP goal too)
  • Attempt this using a more compromised antenna
  • Attempt this during a weekday

It turns out I had a few free hours on Wednesday, December 27, 2023 to play radio…  It was kind of a dismal day weather-wise.  I figured it might be the day to attempt this challenge.  The wet weather had me thinking that I’d setup my SuperAntenna MP1 vertical instead of using the 40m EFHW (and having it and the throw line get all wet and muddy).  The stage was set for the challenge including the stretch goals.

I setup the MP1 on the bedrail of my truck, using an MFJ-1976 ten-foot whip on top.

The band conditions were in pretty good shape, so I figured I had a shot.  I setup the rig inside the truck because of the rain, and got the iPad going with the POTA spotting page to see who I could hunt.  I logged four P2P contacts in the first 20 minutes, so there was hope!

In the end, it took about 90 minutes to log 11 Park-to-Park contacts.  Well, actually 12, since one of them turned out to be a two-fer.  I logged a few “familiar” activators, including Teri KO4WFP – a frequent contributor of Field Reports here, and Jonathan KM4CFT – running a two-fer out of North Carolina.  There were a few that I noted in my paper log because I had a good copy on them, but ultimately couldn’t bust thru the pile ups there were getting (like K7SHR at K-10946 in WY and K0YY at K-4416 in TX).

A personal thanks to all of the activators in my log that helped me reach my P2P Challenge:

  • KL7NL at K-6945 in NC
  • KM4CFT at K-8313 and K-3378 in NC
  • WD4AWD at K-2982 in TN
  • KU8T at K-4208 in IN
  • KO4WFP at K-0659 in FL
  • W0ABE at K-10532 in CO
  • N4XTT at K-2982 in TN
  • NM1L at K-7475 in FL
  • KC1BDJ at K-7879 in FL
  • KI5GBQ at K-7687 in OK
  • NS1C at K-2420 in MA

All contacts were on 20m with the exception of NS1C on 40m.  All were CW.

This was a fun little challenge, one that I hope to repeat in the future.  Hope to see you all on the air – POTA-ON!

KO4WFP: The Countdown Begins with Jack Hill State Park

11 Comments

Many thanks to Teri (KO4WFP) who shares the following guest post:

The Countdown Begins with Jack Hill State Park

by Teri (KO4WFP)

Having completed my kilo for Wormsloe State Historic Site (K-3725) and earned the Marathon Award for the Straight Key Century Club, I needed a new goal into which to sink my teeth. I’ve often set goals in my life as they motivate me to learn and step outside my comfort zone. So what better goal than to activate 60 parks new to me over the next year! I admit it is ambitious; however, goals should excite you as well as make you a little nervous because then you know you are stretching yourself.

How do I plan to accomplish activating 60 new parks? The weeks my son has a break from school offer the perfect opportunity to travel. I can also work in overnight trips to locations in Georgia or South Carolina throughout the year. To save money, I’ll drive on these trips and camp. Most state parks which offer camping are also a park on the POTA list, an easy win-win. For safety, my “POTA pooch” Daisy will accompany me if I am alone, offering an opportunity for the two of us to strengthen the bond we have and work on her training.

My first break-week trip is to Florida during the second week of winter break, December 24th through January 1st. I have nine to ten parks I plan to activate that week, depending on the weather. Daisy and my brother Joseph (no, he is not a ham) will accompany me. Joseph and I took a cross-country trip out west in my twenties and spent six weeks on the road. We mostly camped but also visited friends and relatives along the way.

However, before I leave on my Florida trip, I began my pursuit of 60 new parks with Jack Hill State Park, a park that is only an hour from my new QTH in Bloomingdale, Georgia.

Anyone who knows me knows that I am not a fan of winter. (Spot me this as I live in the Deep South.) However, I am determined to not miss out on POTA because of a little cold weather. Thinking the temperature would be warmer in the afternoon, my dog Daisy and I headed out later than usual on Wednesday, December 13th for our activation.

I enjoy driving in rural Georgia. You never know what you’ll see. Daisy and I went through the town of Bellville, a whistle stop in the middle of nowhere. The town was established in 1890 along the tracks of the Savannah & Western Railroad and was a regional transportation hub for agricultural and timber products. A mural in the town across from the old depot pays homage to the town’s railroad past.

Jack Hill State Park is located in the town of Reidsville, Georgia. It offers amenities that include boating and fishing on the park’s lake, accommodations in the form of camping as well as cottages to rent, a splash pad for kids, and even a free miniature golf course! The park was originally named Gordonia-Altamaha State Park as it is near the Altamaha River. However, it was renamed Jack Hill State Park in 2020 in honor of Senator Jack Hill who was instrumental in the local community.

October Leaf Colors at Lake James: Pairing the Elecraft KX1 and Chelegance MC-750

3 Comments

This past fall was a busy season for me.

So busy, in fact, I completely overlooked an activation video I filmed two months ago (on Monday, October 23, 2023)!

That said, one of the things I love about making field reports and recording videos is re-living activations a second time. It’s fun to remember the site conditions, the weather, the radio/antenna choices, and all of the folks I might have logged.

I enjoyed stepping back in time a couple of months for this one!

Lake James State Park (K-2739)

That Monday was the first day I surfaced to fit in an activation after fighting a respiratory bug the previous week. I felt much better and tested negative for Covid, so I made my way to Hickory to help my parents with some tasks.

On the way that morning, I stopped by Lake James to play a little POTA with one of my favorite radios in the world: the Elecraft KX1.

On October 23–as I mention in the video–the QRP world had only just learned about the new Elecraft KH1 and I had yet to receive the almost-production unit I ordered as a field tester.

I knew that once I received the KH1, I’d be using it heavily for a few weeks, so I wanted to fit in a little KX1 time in advance!

POTA in Color!

The weather and fall colors at Lake James were absolutely stunning!

New KX1 Tufteln Cover!

Back when I filmed this video, it had only been one week since the W4 SOTA campout where my friend Joshua (N5FY) gave me a few prototype snap-on protective covers for my KX1s.

These covers are very clever because they protect all of the important front-panel components yet remain very low-profile so add little bulk to the radio.

Image: Tufteln.com

Joshua provides two new screws for the front panel (you simply replace out the stock KX1 screw); the cover magnetically snaps onto the higher-profile screws and seats itself securely.

Image: Tufteln.com

I demonstrate my cover in the activation video.

At the time, this was a product Joshua was considering adding to the Tufteln line-up–since then, he’s made it available to order–click here to check it out.

At present, Joshua offers the covers in two colors: black and light brown. Mine are the light brown color.

You’ll notice in the video that Joshua added my callsign to the covers he gave me. I don’t think the production covers are customized with your callsign because Joshua makes these in batches. You would need to check with him about customization–I assume there would be an extra charge and lead time for that because it would require modifying the file and printing a one-off cover.At any rate, I love the covers and have added them to all of my KX1s. Note that I used a Sharpie to write the name of each radio on the cover–this makes it very easy to tell the difference between my KX1 models (they’re named Ingrid, Greta, and Ruby)!

On The Air

It was early enough in the morning that I decided to spend some time on the 40 meter band to work POTA “locals.” I deployed my Chelegance MC-750 with the 40 meter coil.

I tested the SWR and discovered it was high due to a loose connection on the end of the cable assembly–I fixed that and the SWR came down to 2.5:1. With the MC-750, I could have easily lengthened or shortened the whip to get a perfect match, but instead I took the lazy (& speedy) route and simply used the KX1 ATU to get a 1:1 match.

Even though I’d spent a long time talking about the KX1, KH1, the Tufteln cover, etc. in the  video, I actually didn’t have a lot of on-the-air time. (Typical me to talk away my activation time!).

I started calling CQ POTA and the contacts started rolling in.

Within ten minutes, I’d already worked ten contacts.

I worked a couple more, then called QRT. Looking at the time, I had to end this activation earlier than I’d hoped. I needed to hit the road again.

I packed up in short order, but still took a few moments to enjoy the beauty of that lovely autumn morning.

QSO Map

Here’s what this five watt activation looked like when plotted out on a QSO Map:

Activation Video

Here’s my real-time, real-life video of the entire activation.  As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.

Note that Patreon supporters can watch and even download this video 100% ad-free through Vimeo on my Patreon page:

Thank you

Thank you for joining me on this activation!

I hope you enjoyed the field report and my activation video as much as I enjoyed creating them. I enjoyed reliving this Octeber activation.

Of course, I’d also like to send a special thanks to those of you who have been 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.

As I mentioned before, the Patreon platform connected to Vimeo make it possible for me to share videos that are not only 100% ad-free, but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.

Thanks for spending part of your day with me!

Here’s wishing all of the you best of the Holiday Season!

Cheers & 72,

K3ES Activates Waco Mammoth National Monument

Many thanks to Brian (K3ES) who shares the following guest post:

The National Park Service welcomes you to Waco Mammoth National Monument

Activating K-0975, Waco Mammoth National Monument

by Brian (K3ES)

At the end of November 2023, my wife and I loaded her minivan, and headed out into the first significant snowfall of the season.  I had already been out that morning in my 4WD truck to pull a friend’s car out of a ditch, so I was driving carefully.  Our drive took us from our home in northwest Pennsylvania to Baltimore, MD.  Happily, weather conditions improved as we went south and east.  We were meeting our son, daughter-in-law, and 2-1/2 year old grandson for a family trip to Waco, TX (we flew out of Baltimore-Washington International Airport early the next morning).  My wife and daughter-in-law are particular fans of Fixer-Upper and Chip and Joanna Gaines, all based in Waco.  Us men-folk were to be educated in the finer points of appreciating this pop-culture phenomenon.  Ultimately, we certainly did appreciate the finer points of dining in Waco.

One side-trip that amazed us all was a 10 minute drive up the road to Waco Mammoth National Monument.  This relatively new addition to the National Park system is also listed as Parks on the Air (POTA) entity K-0975.  Back in the days when the area occupied by the National Monument was private land, two exploring teenagers, who may not have had proper permission, found a bone, a big bone.  This bone was delivered to a local museum for identification, and ultimately determined to have been the femur of a female Columbian Mammoth.  Legalities being as they are, it took a while longer for the location of the discovery to be made public.  An interested and civic-minded land owner made the process less traumatic than might have been, particularly for the wandering teenagers.  He also started the process to preserve the site and its archaeological treasures for the public, ultimately leading to its designation as a National Monument.  Over subsequent years, archaeological excavation discovered a lot more bones – skeletons from an entire nursery herd of Columbian Mammoths, along with skeletons from other species that visited what was apparently a dangerous waterhole during the last ice age.

A view of the interior of the building constructed to protect the archaeological site.  Near the entry door is a full-sized artist’s rendition of a Columbian Mammoth.  Standing up to14 feet high at the shoulder, Columbian Mammoths were significantly larger than their better known Woolly Mammoth cousins.  This site is unique in that the bones of an entire nursery herd, including multiple females and their young, were found together here.
Some of the partially excavated mammoth skeletons contained in the enclosure building.
Also found in this excavation site was a Western Camel skeleton.  It is thought that the large number, numerous species, and wide range of ages of the skeletons discovered at this site resulted from entrapment in thick mud that formed the bottom of a persistent waterhole.

Since the discovery, many skeletons have been excavated and removed for study, but many more remain at the site awaiting future recovery.  A building has been constructed to cover the excavation and protect the remaining skeletons, and this building is the amazing focal point of the Waco Mammoth National Monument.  Ranger-led tours are available, and very much worthwhile.

Operating QRP CW on a beautiful afternoon at K-0975, Waco Mammoth National Monument.  My station is set up in a grassy field sometimes used for overflow parking.

Setting Up to Activate K-0975

After the tour and a look at the excavation site, I excused myself and set up to activate K-0975.  Before the trip, I had sent an email to Phil – WA5PQL, who is the most frequent activator at K-0975.  He was gracious and helpful in providing information about the park, the staff, and the locations most suitable for activating.  His assistance made a quick, low-stress activation a near certainty.  After checking in with the Park Rangers, I had directions and permissions, so all that remained a concern was HF propagation.

While the previous day had been overcast with drizzle, Friday, December 1, 2023, was sunny and warm.  It was perfect for walking around the site, and for an outdoor activation.  Unfortunately, the same sun that gave us the bright, warm day, had been active producing solar flares that could interfere with radio communications.  The only way to know for sure that I could make contacts was to set up my station and call CQ, so that is the path I chose.

Field kit contained in a re-purposed Peltor 4” x 6” x 9” padded headset pouch.  This compact kit was easily packed in a carry-on backpack for airline travel.  The pouch’s integral handle also made for easy transport to the activation site.

I brought a very small, but capable, field kit based on my Elecraft KX2 and a Tufteln End-fed Random Wire antenna.  A couple of CW keys, a short feedline, and generic earbuds completed the station.  I also brought a notepad and a pencil for logging, a plastic garbage bag for seating, and some cordage.  The most peculiar part of my kit was a small pill bottle with a hole in its lid.  I filled the pill bottle with dirt, passed the end of a 2mm line through the lid and secured it with a knot.  I was able to use the dirt-filled bottle as a throw weight to get the line over a tree branch for raising the antenna, then I detached the bottle and returned the dirt.  All elements of the kit worked as intended, and TSA asked no questions during my trips through airport security.

KV4AN’s Icom IC-705 Field Kit

by Steve (KV4AN)

A requirements-driven portable communication capability, using a modular implementation concept, was the basis for my IC-705 Field Kit.  I’ve loved portable radio operating since shortly after getting my license back in 1975.  My first portable radio was the over-the-shoulder Kenwood TR-2200A 2m FM transceiver.  There is now a happy confluence of advanced electronics technology, customer-focused radio manufacturers, radio sport groups like POTA and SOTA, and hams who want to combine outdoor adventures with their ham radio hobby.   The result is the ability to create and operate highly capable portable ham radio field kits, such as the IC-705 Field Kit that I’m going to describe in this article.

The kit consists of up to three man-packable bags: a Radio Bag, an Antenna Bag, and a Computer Bag, as shown in figure (1).  The Radio and Antenna bags must be brought to every activation, but the computer bag can be left at home if I don’t plan to use digital modes.  I can also swap out Antenna Bags, depending on what kind of antenna you need for the specific activation location and park rules, like: ability to use a ground spike, size of activation area, presence of suitable trees, primary operating bands and expected propagation conditions, and so forth.

Figure 1.  IC-705 Field Kit loaded up and ready for a park activation (click image to enlarge).

Radio Bag

The Radio Bag contains everything necessary to operate the IC-705 in the field.  It can be carried in one hand, worn over-the-should, or worn as a fanny pack.  With the load-out listed below and shown in figure (2), it weighs around 15 lbs.

[Gear links list at end of article.]

A. Icom IC-705 Transceiver.  Chosen for its “all-band”, “all-mode” capability with base station features and performance.  It’s a superb, state-of-the art radio, and a joy to operate – but, it “feels” a little delicate with the large unprotected touch screen and protruding light plastic knobs.

B. IC-705 Front Panel Cover. This was chosen to protect the delicate front panel of the IC-705.  I didn’t want one of the cages, because they add bulk and weight to a reasonably small and light weight radio.  This cover fits perfectly, doesn’t mar the radio body, and provides great impact protection when the radio is not in use.

C. Icom AH-705 Antenna Tuner. This is a good antenna tuner and matches the IC-705 (in appearance and electronic functionality) very well.  It is large compared to the Elecraft T1, but it runs off two “AA” batteries, which I really like.  The tuner uses a BNC coaxial patch cable and a 1/8” stereo patch cable for connection to the IC-705.   I don’t need to use this tuner very often as my antenna typically has a low SWR on 40 – 10 meters.

D. Icom HM-243 Speaker-Microphone. The HM-243 comes with the IC-705.  I’ve never used the speaker part of it, but the microphone has good voice reproduction.  If needed, I planned to use the speaker in place of headphones.

E. N3ZN ZN-QRP Special Iambic Keyer Paddle.  I got this marvelous quality and wonderful feeling paddle in beautiful Blaze Orange – so I feel like I’m the radio operator from a downed aircraft trying to get rescued.  The paddle is a little heavy for portable use, but at least it doesn’t move around while sending.  It uses a 1/8” stereo plug patch cable for connection to the IC-705.

F. Tactical Range Bag. This bag was chosen because the IC-705 fit perfectly in the main compartment and there were additional compartments for all the small accessories.  It also came in Army Green color.

G. Icom MBF-705 Desk Stand. Stabilizes the radio when it is on a table or in the Radio Bag and positions it for easy viewing and operating.

Figure 2. Radio Bag and Contents (click image to enlarge).

H. Icom BP-272 Standard Battery Pack. 7.4v, 1880 mAh pack that came with the radio and attaches to the back of it.  I use this as the spare battery pack.

I. Icom BP-307 High-Capacity Battery Pack. 7.2V, 3150 mAh pack that attaches to the back of the IC-705.  So far, this battery pack has been sufficient for my POTA activations.

J. Tactical Drop Pouch.  This pouch fits in the bottom of the main compartment of the Radio Bag and can hold either a Bioenno 12V, 12Ah, LiFePO4 battery or the front panel cover (used as a spacer).  The IC-705 sits on top of the Tactical Drop Pouch when in the Radio Bag, which elevates it enough that the IC-705 can be easily operated.

K. Smiley Antenna Company TRI-Band.  This is a telescoping 1/4 wave 2m and 5/8 wave 440 antenna that attaches directly to the IC-705.  It performs well with the IC-705 and fits inside the tactical bag when collapsed.  Another advantage of the telescoping whip is it can be adjusted for best SWR.

L. USB Cable.  The USB C to Micro USB cable is used to connect the IC-705 to the portable station computer to control the radio and pass audio and data.  This cable is needed, even if you connect using WiFi for rig control and audio, to send GPS NMEA format position and time data from the IC-705 to the computer.  I was told by Icom Technical Support that the cable should not be longer than 3 feet and should have an RFI Choke at each end.  The combination of the short cable, USB C connector instead of USB A, and the RFI chokes seems to help the noise problem that that the IC-705 has when a USB cable is plugged into it.  The other solution is using the RS-BA1 software.

M. Emergency HF Antenna. This is a home-brew antenna with a 24 1/2 foot radiator and 12 1/2 foot counterpoise that attaches to the AH-705 Antenna Tuner with a BNC to binding post adapter.  It is rolled up on a line winder and there is some paracord to hold up the end of the radiator.  This is a back up antenna in case something happens to the regular antenna.

N. Assorted Coaxial Adapters: BNC to SO-239, SO-239 Barrel, BNC Elbow, and BNC to binding post.

O. Tactical Pen.  A nice heavy pen for outdoors use.   Used for logging.

P. All-Weather Notebook. Weather-proof notepad for outdoor use.  Used for logging.

Q. Leatherman squirt E4: A Swiss Army-like miniature tool set with a wire stripper and screw drivers.  It is used to perform minor repairs in the field.  This tool has been discontinued by the manufacturer.

R. Gerber Recon Task Flashlight.   A rugged miniature flashlight that runs on 1 “AA battery and has different color lens.

Antenna Bag

An Antenna Bag goes on every activation.  The primary bag contains the components of the Chameleon Antenna Tactical Delta Loop (TDL) antenna.  The TDL is a versatile antenna that can be configured as a small Inverted Delta Loop or a 17 foot ground mounted vertical.  I usually use the 17 foot ground mounted vertical configuration because it takes less than five minutes to deploy, performs well, doesn’t attract much attention, and does not require a tuner for 40 through 10 meters.

The Antenna Bag itself is the Sunrise Tactical Gear, Tactical Tripod Bag Gen 2 (32 inch length).  It is exceptionally durable and holds all the components of the TDL antenna.  It can be worn across the back for easy carrying.  The Antenna Bag and all components weigh around 11 lbs.

The Lifeline of CW and POTA

by Teri (KO4WFP)

The past five months have been tumultuous. I am now divorced and my son and I are making a new life for ourselves with my family. Those of you who’ve been through a divorce know how stressful and difficult a process it is, especially when navigating it for the first time. You are undoing relationships and patterns of behavior and figuring out how to move forward and what that looks like.

Why do I tell you this? Partially because I want those of you who’ve said “where the heck have you been?” to know why I’ve been absent from QRPer. However, I also want to thank all of you in the ham community because it is this community that saw me through my difficulties. Hams are some of the kindest and most wonderful people, especially CW and POTA hams. This community has rallied to my side and given me a reason to keep moving forward.

As Thomas noted in his September 17 post of this year, CW is indeed “radio therapy.” After I relocated, it was six weeks before I had a home station again. Six LONG weeks without seeing my code buddies – Caryn KD2GUT, Glenn W4YES, and Charles W4CLW – on the air. I felt cut off not having those QSOs, not being able to get on the air when I desired, like someone had removed my legs! The absence reinforced how much CW and POTA mean to me.

While working to get a home station again, I latched onto POTA. I vividly recall driving home from my first POTA activation after leaving my ex-husband and, for the first time in several weeks, the stress temporarily melted away. Life, for a few hours, felt normal. I felt like my old self.

CW and POTA were indeed therapy as I put my life back together. Getting out and activating was good for my mind and body. Ham radio for me is about relationships and seeing ops who hunt me regularly was like reconnecting with friends saying “hi”.

POTA became an integral part of my healing process and I pursued activations at George L. Smith State Park and, my old stomping ground, Butter Bean Beach, part of Wormsloe State Historic Site.

George L. Smith State Park is a pretty site for POTA. The park’s focal point is Mill Pond Lake which was created by the damming of 15-Mile Creek in 1880. Visitors can rent kayaks or canoes to explore three paddling trails in the 412-acre lake and its wetlands but are warned against swimming due to the presence of alligators. The land adjacent to the lake has seven miles of nature trails through sand-bottomed forest with hardwoods and longleaf pine.

The old mill at the site still exists. The original floodgates are used to control the water level in the lake with the addition of an electric hoist to open and close the gates. The mill, known as Watson Mill, is housed in a bridge which was open to motor traffic until 1984 and is one of only two mills operated by the State of Georgia. Watson Mill housed a sawmill for lumber as well as a gristmill, the latter which remains operational for demonstration purposes.

After a quick drive through the park, I chose to set up on the hill next to the park office which offered an open area without adjacent power lines. It wasn’t long before my EFRW was installed in a tree and I was on the air. Continue reading The Lifeline of CW and POTA →
