Major POTA fun with the TEN-TEC R4020 and PackTenna 20M EFHW!

4 Comments

The other day, I was thinking…

If  2014 Thomas looked at 2024 Thomas’ QRP radio inventory, he wouldn’t believe the number of radios he’d accumulated in a mere decade.

It’s a little insane, really.

The thing is, over the years, I’ve picked up some great QRP bargains at local hamfests and via various online classifieds. While it’s not exactly “chump change,” you can often find good used QRP radios for less than $300.

Sometimes it’s hard (for me) to pass up those deals.

One such deal was a local fellow who wanted to sell his Ten-Tec R4020 a few years ago.  He listed it for $125, and there weren’t any takers for a few days. (Keep in mind, this was a wee bit before our current CW Renaissance.)

I contacted him and snapped it up. I thought the R4020 might be a fun little two-band radio for POTA and SOTA adventures.

I was right!

The R4020 is an incredibly fun radio to use in the field.

The audio is superb. It has a low noise floor, great sensitivity, and a well chosen filter width. What the R4020 lacks in features, it makes up for with audio fidelity, in my opinion.

I look forward to each and every activation with this QRP wonder.

Speaking of which…

Tuttle Educational State Forest (K-4861)

On Wednesday, January 3, 2024, I made some time in the afternoon to stop at Tuttle Educational State Forest.

I believe I was on the way back to the QTH that afternoon after an overnight with my folks in Hickory, NC.

I love Tuttle, but it had been a while since I completed an activation here. In the activation video (below) I said it had been a couple of months, but later I checked and realized it had been four months! Wow! Hard for me to believe it had been that long!

That day, the park was void of visitors. I was the only person in the parking lot. No surprise here: kids were just heading back to school after a long Christmas break, so there were no field trips on site.

Since there was no competition in the picnic area, I decided to grab a site I might not have actually used before in previous Tuttle activations. I’m evidently working on my WATPT (Worked All Tuttle Picnic Tables) award!

First, a quick inventory…

Before heading to Hickory the previous day, I grabbed the little Blue Ridge Outdoors pouch that held my R4020 and much of the supplies I’d need to get on the air.

I knew, though, that this wasn’t a fully self-contained field kit. Not yet, at least. I hoped that between my main radio gear pack and what I had in the car, I could piece together an entire station.

In my activation video, I speak to the mental checklist I use to make sure I have all of the necessary components to complete my field kit. I did this on site as I set up (typically, this is done prior to leaving the QTH).

Fortunately, I had everything I needed, including an external speaker.

Side note: Some of you might notice the (disproportionately) large Bioenno battery I used during this activation. Yes, it’s crazy overkill for this wee QRP radio. I’d normally use a 3Ah battery, but frankly, I need to exercise my 15Ah battery from time-to-time, too! It gets the least amount of field time because I normally save it for my QRO radios that I use so little in the field.

On The Air

I’d packed my PackTenna Mini 20 meter EFHW with the R4020.

My 40 meter PackTenna EFHW would have been a better choice–since it would have been resonant on both of the R4020’s bands (20 and 40M)–but at the time of day I was operating, I knew 20 meters would serve me well, so 20 meters it was!

Visiting VOA Site B: The Edward R. Murrow Transmitting Station

by Bob (K4RLC)

Two week sago, Dale (W4AUV) and I were treated to a “under the hood” visit to the last remaining Voice of America transmitting station in the United States. It is located in eastern North Carolina, and officially known as the “Edward R. Murrow Transmitting Station” part of the “Office of Cuba Broadcasting” in Grimesland, North Carolina. Also, known as “VOA Site B.” This type of shortwave broadcast station is only one of a few remaining worldwide.

[Note: Click on images to enlarge.]

VOA QSL Card showing some of the 38 antennas

This VOA site has been on the air continuously (24/7/365)  since the 1963 on-site dedication by President John Kennedy, broadcasting up 8 transmitters at a time on the short wave bands. There are three 250,000 watt and five 500,000 watt GE, Continental and Telefunken  transmitters feeding 38 possible antenna configurations, with an Effective Radiated Power of 2,000,000 watts. (There is also a 39th antenna, that is a Dummy Load that will handle 500,000 watts).

The antenna field covers over 6,000 acres of flat, costal plain wetlands, not far from the  Atlantic Ocean, so it has a minimal absorption factor and a salt water boost.

TCI “Curtain” antenna made of 4 dipoles wide & 6 dipoles high, pointed at Cuba. It is controllable in both vertical and horizontal azimuth, depending on the configuration has to up 23dB gain at a 4 degree take off angle

The antennas are fed by over 26 miles of 300 Ohm open line “ladder line” with a minimal SWR and minimal signal loss. The largest antennas are called “Curtain” antennas, given their configuration, of matched horizonal and vertical dipoles suspended between large towers, giving the visual impression of huge curtains.

There are also  rhombics, each 6 wave lengths long. The rhombics are not used as often, given their narrow bandwidth and narrow beamwidth. The Curtains can bathe a large geographic area (such as part of a continent) with a very strong signal. The primary broadcast areas for this station are Cuba, Central and South America, and Africa (although the antennas could reach out and touch Russia and eastern Europe, when needed).

Glenn (W7GSW), a US Navy communications vet, has been at the site many years and conducted much of the tour for Dale and I. Continue reading Proper QRO: K4RLC Tours The Edward R. Murrow Transmitting Station →

W7UDT: “Velcro, ergo; ergonomics…”

Many thanks to Rand (W7UDT) who shares the following guest post:

Velcro, ergo; ergonomics…

by Rand (W7UDT)

Velcro is amazing. It’s so handy. There are so many uses, and creative solutions it provides us. It’ll stick this to that, and that to this. As field operators, it should be part of our kits.

Below are some examples of how I’ve used Velcro.

Question: How do you keep a Android tablet, a 3aH 12v DC pack, a QRP Labs QDX LoBander, all its cords & patches, plus an EmTech ZM2 tuner all nice and tidy? Velcro!

Here’s the old QDX kit…

Here’s the new (velcro’d) QDX kit, complete with EmTech ZM2 tuner, neatly attached on the back of the Tablet, with the QDX and DC Pack. It all fits in a zippered pouch, along with the EFλ/2 antenna, perfect for the QDX.

The new QDX kit even sits at a nice viewing angle, with all of the cords hidden from view. Ergo, ergonomics.

Question: Where & how do you safely place your transceiver on a rugged SOTA/POTA activation, so it won’t get damaged?

How? Velcro! What makes more sense? A precarious rock, or the Molle patch on your pack?

This is my QCX Mini ~ Forty, Velcro’d with two horizontally applied 1” strips, with short cords channeled between them. It secures the perfectly mated 3aH 12v TalentCell battery, to which I applied another velcro strip to hold fast the Palm Pico paddle. Also note the ‘D-shaped’ earpiece/speaker, on the BNC jack. It’s hung and velcro’d just above the paddle.

Since this photo, I’ve added three 2×4” (cut to fit) patches to the front, back and bottom of the QCX Mini & TalentCell, which neatly bundles this little QRP contraption and transforms it into a QRP wonder! Now it all fits in my hand, or attaches firmly to my pack. Dit dit dit daw! Velcro!

A view from Zion NP, in the backcountry… late last Spring. Where my little transceiver tried to commit suicide.

Just sayin’… Velcro may be just the answer you’re looking for.

POTA with Jonathan (KM4CFT) at the Zebulon Vance Birthplace (K-6856)

4 Comments

On Thursday, December 28, 2023, I had the good fortune of meeting up with Jonathan (KM4CFT) at the Zebulon Vance Historic Birthplace (K-6856) to play a little POTA.

You might recognize Jonathan’s callsign because he has a popular YouTube channel and also produces excellent EFHW antenna kits.

These days, Jonathan lives in Colorado, but he’s originally from western North Carolina. We met once before when he was in town visiting his folks. That previous time was very short, though; this time, we wanted to meetup and fit in a POTA activation together.

We arranged to meet around 2:00 in the afternoon at the Vance Birthplace.

We decided to deploy one of Jonathan’s End-Fed Half-Wave antennas. He cut this particular one for 20 meters.

We set up under the picnic shelter with the antenna essentially in a sloper configuration.

Gear:

Note: All Amazon, CW Morse, ABR, Chelegance, eBay, and Radioddity links are affiliate/partnerhip links that support QRPer.com at no cost to you.

I brought along a couple of radios that Jonathan had yet to operate. He chose to use the Penntek TR-45L (great choice!).

One wrinkle: Jonathan operates with his paddle in “reverse” with the left paddle sending dashes and the right sending dits.

Unfortunately, the TR-45L doesn’t have a software function to flip between “normal” and “reverse” settings. No problem, though: Jonathan simply turned his key (a BaMaKey TP-III) upside down! Problem solved!

The only annoying issue was the 45L speaker–something inside the chassis or speaker assembly was rattling/buzzing with louder signals and with the sidetone. After noticing the speaker vibration at an activation in South Carolina a few months ago, I opened up the TR-45L at the QTH and tried to tighten down anything that could resonate inside the chassis. My fix seemed to work until we powered it up for Jonathan to use. I may have to add some padding around the speaker assembly if I can’t locate the culprit inside the radio–it could be pretty much anything.

Jonathan plugged along and paid no attention to the buzz, nor my fiddling with the radio while he operated. (You’re a good sport, OM!).

Here’s Jonathan’s QSO Map:

After he completed his activation, Jonathan handed over the radio to me.

Since I couldn’t sort out the acoustic buzz/vibration without opening the radio on the picnic table, I opted to swap out the TR-45L with my Discovery TX-500.

I hopped on the air and logged quite a few stations on 20 meters. It was serious fun!

Here’s my QSO Map:

POTA Meetups

Jonathan, it was great hanging with you and, again, I’m so impressed with your CW progress. It seems like only yesterday when you started your CW journey!

When folks are passing through western NC it can be difficult for our schedules to align for a POTA meetup,  but I’m so happy when they do.

Thank you!

Thank you for joining us on this joint activation!

I hope you enjoyed the field report and ctivation video as much as I enjoyed creating them.

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! Have an amazing weekend!

Cheers & 72,

Thomas (K4SWL)

K4FMH: “A Living Language? Or Eu tu, Brute?”

9 Comments

I love it when my good friend, Frank (K4FMH), explores amateur radio topics through his academic lens.

Frank recently posted an article about living languages and how that could even apply to our amateur radio/QRP world. It’s a fun read and possibly worthy of a peer-reviewed journal (if they allowed humor)! Thank you for sharing, Frank!

POTA Postcard Field Report: Finally Snagging a Kilo on the Blue Ridge Parkway (K-3378)

30 Comments

It’s funny: I’ve met POTA activators who’ve been hitting the field for only a couple of months and have already obtained a “Kilo” award for confirming one thousand QSOs from the same Parks on the Air entity. Most of my active POTA friends have multiple Kilos.

Me? Until December 29, 2023, I had never obtained a Kilo at any POTA site!

Something you should know about me: I don’t check my POTA stats or awards frequently…as in maybe once or twice a year–?  I’m the same with my YouTube stats and even website stats. I’m just not a terribly numbers-motivated person.

That said, I fully recognize that numbers give us a snapshot of how and where we activate. Only recently, I checked my awards page to see if I’d ever snagged a Kilo and was surprised to find that no, I had not.

I say “I was surprised” but truth is, my activations tend to be really short. I think my average number of logged hunters per activation is probably 20-25.

I checked the POTA website and I had 48 activations in the books for the Blue Ridge Parkway (K-3378). My total number of contacts confirmed was 994.

Yeah, I was six contacts short of a Kilo. What!?! This needed to be remedied!

So technically…

The KX2 was my NPOTA companion (pictured here at the Carl Sandburg home during NPOTA).

In truth, I probably could have achieved a Kilo much earlier because POTA allows you to submit logs from 2016’s ARRL National Parks On The Air (NPOTA) event. During NPOTA, I activated the Blue Ridge Parkway (guessing here) about 50 times; it was my most accessible NPOTA park and I hit it several times a week. However, I have not submitted my NPOTA logs to POTA, so my POTA numbers do not reflect my NPOTA activities.

Postcard field report

I’m still catching up after a challenging first few weeks of 2024. In fact, since I made that post, so much more has happened. January 2024 has been a tough month.

I’m nearly a month behind on email, so if you’ve written to me with questions, you likely haven’t received a reply. I’ve simply needed a break during this time.

Speaking of busy, I have a pretty hectic day in store, but I’m eager to post one of my field reports (I enjoy this) so we’re going to do it “postcard” style. I’ll let my activation video and logs tell the story of this brilliant little activation on December 29, 2023.

Spoiler alert: I got my Kilo!

N2YCH: January POTA Travel in Frozen Alaska!

3 Comments

Many thanks to Conrad (N2YCH) who shares the following field report:

Conrad’s January Alaska Activation

By: Conrad Trautmann, N2YCH

“Why would you go to Alaska in January?” is what everyone asked me.

I’ve wanted to see the Northern Lights for as long as I can remember. The best time to see the aurora borealis is between late August to late April in Fairbanks, Alaska. Days are short in January, sunrise is at 10:24am local time and sunset is at 3:38pm. It’s twilight before the sun comes up and after it sets so it’s not pitch dark, but it’s mostly dark for about 19 hours a day in Fairbanks at this time of year. Once I began researching, I learned that peak viewing times for the aurora are between 10p and 2a local time even with the extended darkness. Check aurorasaurus.org for more information.

So, the answer to the question is, “The odds are better to catch the Northern Lights in the winter.”

Cold weather and snow doesn’t bother me having lived in Syracuse, New York for ten years. I have experience with winter weather and driving. Fairbanks is one of the best places in the state to see the aurora since it is directly below the “Aurora Oval” and it has over 100 days a year when the aurora is visible. Except for January 12th through the 15th, 2024, when the sky had 98% cloud cover and it was snowing. Aurora viewing was not happening during my visit.

However, this trip was not a total loss by any means. There are things to see and do here, including activating parks! I activated three parks in three days, Denali National Park (K-0022), Chena River State Recreation Area (K-7228) and Creamer’s Field Wildlife Refuge (K-9697). I’ve heard stories from hams in Alaska that propagation can be spotty, that there can be total radio blackouts from solar flares and that bands we don’t usually worry about in the lower 48, like 20 meters, can be useless at times. I packed enough equipment and antennas to activate on any band from 40 meters to 6 meters, up to 100 watts using my Elecraft KX3 with the Elecraft KXPA100 amplifier. On the first day at Denali, I used the amp for the entire activation, but I realized at the end of the day that Thomas, K4SWL, who runs “QRPer.com” wouldn’t be too happy with a field report from “QROer.com” Conrad, N2YCH. To remedy that, I activated my second park using just my KX3, no amp. At K-7228, my first 11 QSO’s were QRP and the park was officially activated using only QRP power. I activated my third park QRO, read on and I’ll explain why.

[Thomas here: For the record, readers, I gave Conrad a Special Use Permit to mention QRO on QRPer! Ha ha! Of course there’s no problem going QRO from time to time!]

Back to propagation, I emailed one of the most active POTA activators in the area prior to my trip to get a sense of what to expect. I highly recommend doing this for anyone planning to travel somewhere and activate. Look at the POTA pages for the parks you want to activate and you’ll surely see a repeat activator with a Kilo award or many visits to those parks. They know the parks the best and also what to expect for propagation. They also share your passion for POTA and are usually very happy to help. The advice I received was that it would be difficult to make contacts on 20 meters and that watching the MUF (maximum usable frequency) charts would serve me well. (Check out hf.dxview.org) The activator said 10 meters would probably be the best band during daylight hours. He was exactly right. Even with QRO power, 20 meter reception in Alaska was noisy and my signal did not get out very far on FT8 watching the pskreporter.com spot map. I moved to 10 meters and quickly had a steady pile up. I stayed on the air until I depleted a 9ah and a 3ah battery I brought. What fun!

Okay, so for the QRP activation, I was at a trailhead parking area out near the Chena Hot Springs resort. Before the activation, I stopped and did the tour of the Aurora Ice Museum and took a dip in the natural hot springs. I do recommend the hot springs if you ever go to Fairbanks. It was -10F degrees when I was there, quite an experience.

Chena Hot Springs

I intentionally wanted to delay my activation from early morning to closer to sunset to see if operating during the evening gray line passing over would help improve the number of contacts I could get. The short answer is that it was worse…way worse. I went back to activating closer to sunrise on my third day and had similar results as I did the first day, much better. Sunrise wins.

The map above shows my initial ten QRP QSO’s from K-7228.

What really continues to amaze me is just how far my signal can reach with the portable equipment I was using. I brought the Buddipole so I could configure it as a vertical or a dipole. I tried it as a vertical on 20 meters on my first day and as I said, the reception was poor. The beauty of the Buddipole is that I could quickly reconfigure it to a 10 meter dipole. With the tripod, it’s roughly 10’ off the ground. There was no wind to speak of, so I didn’t need to guy it. If there was, I would have used a bungee cord to secure it to the car bumper or side mirror.

It breaks down and fits in the bag I bought with the Buddipole tripod and I tossed it into my checked bag on the plane. With the tripod and mast, it’s just a little too long for the carry-on bag. I could have brought a fiberglass push up mast and wire antennas in my carry-on, but I decided on the checked bag and brought the Buddipole to have as many options as possible. After all, I was traveling all the way to Alaska. Continue reading N2YCH: January POTA Travel in Frozen Alaska! →

Scott’s Self-Supporting Random Wire Antenna System

5 Comments

Many thanks to Scott (KK4Z) who shares the following post from his blog KK4Z.com:

K4SWL+ Antenna

by Scott (KK4Z)

On a recent post on QRPER.com, Teri KO4WFP was at a park in Florida that did not allow wires (or anything else) in their trees. Many POTA activators use End Fed Half Wave antennas which usually require one end in a tree. While it doesn’t happen at all parks, not being able to hoist your antenna could bust an activation.

I realized this may happen to me even though Georgia appears to be pretty lenient when it comes to such matters, I decided to switch to a park friendly antenna. I have been a fan of QRPER.com for quite some time and occasionally Thomas will repost something from my humble blog. That being said, it was K4SWL that got me started using a random wire antenna. My basis for my antenna was his speaker wire antenna which was a 28.5’ vertical antenna with a 17’ counterpoise. I used it a few times in that configuration and then started to modify it. I call this antenna my K4SWL+.

Some of the differences are I use a push-up pole to get the antenna in the air and at the base I use a 9:1 UnUn and a 1:1 Choke to keep RF out of the radio. A random wire antenna can feed RF back into the coax.

The wire is 14 ga. coated flex weave from The Wireman. This was left over wire from some other antenna projects. When I started this project I was using 22-24 ga. coated wire from SOTABeams but realizing there was no need to save weight, used the heavier wire. This allows me to dual purpose the antenna both for FunComm and EmComm. The insulator at the top is 3D printed with my call-sign and the base is U-type lugs. I find these are the best as I do not have to take the nut off of the antenna studs and if pulled hard will come loose instead of damaging the UnUn. I connect the antenna to the top of the push-up pole with a small Nite-eze “S-biner” size 1.

The 9:1 UnUn comes from Palomar Engineering. I have already created a blog post about how to build it and it can be found here: https://kk4z.com/2022/05/28/91-unun-qro/

Part of this blog post was to bring the different components together into one blog post.

The 1:1 Choke can be found here: https://kk4z.com/2022/08/15/lightweight-choke-balun/

I made two different types but I found the second works much better.

The project is pretty easy, the only caveat is to pay attention to what wire goes where. Putting it all together, you need a push-up pole, a Flag holder and maybe a trailer hitch extender. I will provide links below. The Flag Pole holder I used was not available so the link I used is a probable substitute. I have a trailer hitch on both my truck and my camper, When I pull into a campsite I have a choice of which hitch to use to keep my antenna clear from the trees. With the antenna up, I wrap the antenna wire around the push-up pole from tip to base, to prevent the wire from sagging near the tip. I attach the UnUn and choke to the mast with Stretch Velcro Straps. With my antenna up I have park employees drive by me all day along. Most of the time we exchange a friendly wave and occasionally one will stop by for a chat. I have had zero issues with this antenna at any of the parks I have visited.

How does it play? It has pretty much been a main antenna for just about all of my POTA activations. You can go back through my blog post and see what equipment I used with the antenna and the accompanying QSOMap. You do need an antenna tuner with this antenna and I typically use an LDG Z-11 Pro which I’ve had for 15+ years. The antenna tunes up from 80 to 6 meters and I have run the power as high as 65 watts. I normally run 10-35 watts depending on band conditions. I have tried it on 160 meters and while I can get a match, I don’t think much RF is leaving the antenna. I’ve made a few contact with it on 160. If you like to work 160 meters during a POTA activation, I suggest a Chameleon EmComm II with a 60’ antenna and a 50’ counterpoise. I run it as an inverted L with the apex about 20’ up my push-up pole and the end sloping down to something not a tree. Last time I tied it to the lantern stand at the campsite. It worked pretty well and I was able to make contacts on 160.

Pedestrian mobile POTA hunting on the back forty!

7 Comments

Saturday (January 20, 2024) was the first day in weeks that I had nothing on my schedule. There was no pressing need to leave our mountain home and we had a fresh layer of snow on the ground.

When I woke up that morning, it was 4F/-15.5C but by the afternoon it has warmed up to a balmy 10F/-12C (but then back to 0F/-17.7C that night).

It was the POTA Support Your Parks Weekend and part of me wanted to hit the road and activate a park or two. But my desire to stay put, relax, and just enjoy reading a good book by our wood stove, cup of coffee in hand, won out.

As I mentioned in previous posts, we’ve had a lot going on in our family. To have a day where nothing was required of me? I needed to take that.

Still, I did have a few household things to do including stocking up on firewood.

While I was splitting kindling in the crisp air, I thought it might be awfully fun to take the KH1 into the woods and just do a little POTA hunting. As soon as I replenished the firewood in the house and while I had my boots on, I grabbed my KH1.

“What dis? We gonna’ POTA, Daddy?”

Hazel is not a cold weather-loving dog, but she can’t resist heading outdoors with me. Even if it’s just on our own property!

My goal? To do a little pedestrian mobile park hunting with the KH1.

I didn’t care how many contacts I made–if any–with my wee radio, four foot telescoping antenna, and a few watts of power. This was all about winter radio therapy.

I also grabbed my camera to make a short video–the first time I’d picked it up in a couple of weeks.

Instead of detailing any contacts I made (spoiler: I did make a few) I’ll leave that to the video below.

As always, when you’re QRP and not the DX (ie. you’re hunting or chasing, not activating) you need to call activators slightly off-frequency so that your tone varies from the stronger stations calling them zero-beat. Note that this is applicable to operating SSB as well.

I remember when the KH1 was first announced, I read messages and comments stating that such a compromised antenna and low-power radio would not work for hunting Park-To-Park or Summit-To-Summit contacts because it wouldn’t be heard in a pileup.

That’s simply not the case and I knew it wouldn’t be because for years I’ve used my KX2 and AX1 antenna combo to make hundreds of similar contacts. The KH1 is basically an AX1 and transceiver combined in a handheld unit.

It does help, though, to employ a little QRP skill in the process.

Video

Here’s my real-time, real-life video of this little field session.  As with all of my videos, I don’t edit out any parts of the on-air time; I just start recording and let it roll. 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:

Field reports resuming!

Hazel was absolutely running wild as we walked back to the house. I snapped this photo of her as she was jumping around.

I decided to push this short video to the front of the line. You’ll soon see more field reports pop up from December.

As I mentioned in the video, I took a good two week break because I simply didn’t feel like writing or making videos–I was taking some time with family to grieve and be there for my father and sister. My policy is that I never, ever feel pressed to post on QRPer or YouTube because that would make this feel too much like a job.

It’s not a job: it’s a pure labor of love!

And I will keep it that way. This is why I never look at my YouTube stats and only rarely check out my website stats. Those things don’t really matter to me and they’re certainly not a motivator. What is a motivator is the amazing community we have here–that means more to me than my subscriber count, views, and all of those metrics ever could!

Thank you

Thank you for joining Hazel and me on this little POTA hunting session!

And thank you again for the outpouring of kind and compassionate messages as we’ve navigated the past couple of weeks as a family. It’s appreciated more than you know.

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.

Thanks for spending part of your day with me and have a wonderful week ahead!

Cheers & 72,

Thomas (K4SWL)

Quick Update and Thank You…

38 Comments

I would like to thank all of you for the kind comments, messages, and notes of support after my last field report when I mentioned that my mother was in Hospice care.

Mom passed away peacefully and surrounded by family on Sunday afternoon after a long battle with cancer.

Now I’m devoting time to being with family and caring for my father-in-law who was admitted to the hospital ICU on Monday.

Yeah…2024 has had a rather rough start.

Again, thank you so very much for your thoughtful and loving comments and messages. I appreciate them more than you can imagine. Our radio community here is such an amazing one and I’m incredibly grateful.

Thank you!

Thomas
