From the Archives: A 2022 Postcard Field Report and Activation Video from New River Gorge National Park

These are busy days for K4SWL

These past few weeks have been absolutely crazy for me in terms of activity–I’ve been traveling a lot, doing (involved) DIY projects on the house, searching for a new car, planning a PV system for the QTH, fixing well pumps, helping friends, and doing caregiving for my folks.

It’s all kept me very busy!

I have a sizable backlog of emails that have accumulated during this time. If you’ve sent me a message, I likely haven’t read it yet. Apologies for that. I simply haven’t had time to read and reply.

I thought about skipping a field report this morning, then I remembered an amazing West Virginia camping trip and draft videos I’d already uploaded to YouTube.

In lieu of writing a full field report (and so that I can share a video today) I thought I’d simply share this activation video with a Postcard type field report.

2022 West Virginia POTA Camping Trip

Last year (2022), in lieu of going to the Dayton Hamvention, my buddies Eric (WD8RIF), his son Miles (KD8KNC), and I spent a long weekend activating parks and camping in the New River Gorge area of West Virginia. Click here to read more about that trip.

The camping trip was absolutely amazing and we activated a number of parks during that time.

I made activation videos at most of the parks we visited, but with my summer travels and activations in Canada last year, I skipped over several of the videos I’d uploaded so that I could publish my Canadian activations while I was still in Canada.

New River Gorge National Park (K-0696)

 

The following activation video was made on May 21, 2022 as WD8RIF and I activated K-0696.

 

I’ve yet to re-watch this video myself, but I remember clearly that this particular day we had atrocious band conditions.

Indeed, rough bands were present during much of our weekend camping trip, but it never stopped us from having fun or activating our parks.

In terms of gear, I used my trust Elecraft KX2 paired with my Chameleon MPAS 2.0 antenna system.

An Accidental Three-State POTA Rove!

An Accidental Three-State POTA Rove

by Joshua (N5FY)

I often find myself playing radio in the evening when I travel out of state for work. I especially enjoy adding another state to my list of activations. So, a trip to the Sioux City area was great, as I could activate in South Dakota and Nebraska, both new states to add to my POTA activations.

Of course, you are wondering how one accidentally completes a 3 state POTA rove,  so I’ll get into the details in a bit. Believe me though, it wasn’t because I had a fool-proof plan. I do believe that failing to plan is planning to fail. But in this case, a bit of luck and agility on my part, with the bands cooperating, and with the POTA hunter support, I did indeed complete 3 POTA activations, in 3 states, in under 2 hours!

Go Ruck Bullet fits inside the G2 ready for Travel

To be honest, I rarely put much effort into planning an activation while traveling as I simply may not have any time get out to a park, and of course, playing radio is not the purpose of my trip. I often find myself spending just a couple minutes looking at POTA locations before a trip and even may look last minute after I land, before I get off the plane, looking for a good POTA location. Maybe I like the urgent planning excitement, or maybe I don’t want the disappointment of not having the chance to go activate after spending time planning the outing? Again, I do recommend a bit of planning, so don’t exactly follow my example here.

As a result of my minimal planning I typically find myself with a very impromptu, “wing it” style activation. This trip was certainly no exception. I only had one evening to check off both South Dakota and Nebraska. There were parks which seemed readily accessible, but I hadn’t really verified activation numbers or best location on the park property to setup. I did save a few parks in the 3-State area, including Iowa.

I already had an Iowa activation, so I wasn’t as worried about hitting the IA park.

Once my evening freed up, the first day I was in the area, it was already a late in the evening, so I was in a bit of a rush as I headed to the first park. I figured I would hit South Dakota first then drop down to Nebraska and spend a bit more time calling CQ there according to how much daylight I had left.

POTA Park in 3 States surrounding Sioux City

I arrived in the area of the first park–a state park land. As I approached the boundary, I found a horse trail parking lot with some nice-looking trees for a throw line and wire antenna. As I was in a hurry, not needing a hike, I  knew this would work well. I’m not one to play radio from the car, but in this case, it would cut down a bit on the time needed so I could get to the second park.

I threw a line and pulled up my antenna. Within 10 minutes of parking, I had my station setup and scanned 20m to see what shape the band was in. I typically put up a 20m EFHW and hope for the best, and this usually doesn’t disappoint. I then setup my log and found a surprise. Continue reading An Accidental Three-State POTA Rove! →

POTA on Mount Mitchell: The new REZ Ranger 80 and how to use the Over/Under method to coil wire and cable

1 Comment
The REZ Ranger 80 antenna system ships with everything you need, including a nice backpack.

Back in March, I received an email from Mike Giannaccio (W5REZ) the owner of REZ Antenna Systems–he was curious if I’d like to check out his REZ Ranger 80 antenna system.

At the time, my plate was pretty full, so he arranged to send it to me on loan in July.

If you’re not familiar, the Ranger 80 is a portable vertical antenna with a tuning coil at the base that employs a sliding tap for tuning. The Ranger 80 will cover anywhere from 80 – 15 meters without needing any sort of external matching device (like an ATU).

The Ranger 80 Tuning Coil.

If you’re familiar with the Wolf River Coils antenna systems, then you’re familiar with this type of vertical antenna. The difference is that the Ranger 80 is built to what I could only describe as MilSpec standards.

Much of the Ranger 80’s components are CNC machined from premium materials. It sports a Delrin body, black anodized 6061 aluminum, and all stainless steel hardware.

This is not a featherweight antenna: it has the heft to match the caliber of materials used in its construction. It’s not an inexpensive antenna either–it’s currently about $560 US at DX Engineering.

The base of the Ranger 80: note the beautifully CNC-machined holes for the four counterpoises.

The Ranger 80 is also rated for 500W SSB and 250W CW/Digital–in other words, quite a bit more power than I’d ever use in the field, but this design will make activators and field ops happy that like to push some wattage.

I was curious how easy the Ranger 80 would be to deploy and tune, so on Sunday, August 6, 2023, I took it to one of my favorite parks on the planet.

Mount Mitchell State Park (K-2747)

I wasn’t alone on this trip: it was a proper family picnic with my wife, daughters and, of course, Hazel.

The weather was very moody that day–driving up to the park, we watched clouds and mists rise up through the trees like waves crashing on a rocky coast line. Continue reading POTA on Mount Mitchell: The new REZ Ranger 80 and how to use the Over/Under method to coil wire and cable →

A Speedy QRP POTA Activation of the President James K. Polk State Historic Site

1 Comment

On the morning of Tuesday, July 25, 2023, I packed an overnight bag, grabbed my Elecraft KX2 and Chelegance MC-750 then drove to Charlotte, NC.

I go to Charlotte very rarely these days, but somehow in July of this year, I managed two separate visits. Before that, I think I was last there four years ago to catch a flight to Denver.

My main excuse for visiting Charlotte on the 25th was to give a presentation at the Mecklenburg Amateur Radio Society’s monthly meeting.

Since I was in Charlotte for most of the afternoon, I also used it as an opportunity to do a bit of car shopping and test driving. Very soon, I’ll have two new drivers in the family, so we plan to add another vehicle to the mix sometime within the next few months.

While driving to Charlotte I contacted the President James K. Polk State Historic Site. I had never visited this site before so wasn’t sure what to expect. I did a bit of research Monday evening and discovered that their hours were from 9:00 AM to 5:00 PM; typical hours for NC State Historic sites.

I knew my schedule would be tight. The park is located on the south west side of Charlotte (in Pineville) and my 3:00 test drive was in the north east part of Charlotte. If you’ve ever driven in Charlotte, you’ll know that driving times are unpredictable once 4:00 hits. I figured I might not arrive until 4:30 or later.

En route to Charlotte, I called the park to ask for permission to do an activation. Anytime I plan to activate a smaller park like a historic site, I always seek permission first from the park staff in advance. Often, they have restrictions about where you can set up and the types of antennas you can use (some historic and archaeological sites, for example, don’t allow any stakes in the ground or lines in trees).

The park staff gave me a thumbs up to do the activation. I didn’t expect them to deny me because this particular park has been activated over 150 times. No doubt, it’s so popular because it’s the closest park to the Charlotte metro area.

I then asked the staff if they closed all of the park grounds at 5:00 or only the visitor’s center. My hope was that, like the Vance Historic Site, they left the park gates open after hours. Unfortunately, the staff member confirmed that they do indeed close the entire site at 5:00, but he added, “you can certainly do your activation up to closing time, though.” He knew I would be pressed for time to fit in this activation.

Fortunately, I made good time to Charlotte and actually was able to bump up my appointments. I finished my last test drive a little after 3:00 and made a beeline for the park.

I arrived on site around 4:00 PM.

President James K. Polk State Historic Site (K-6848)

Before hitting the picnic area, I walked into the visitor’s center to ask where they prefer that I set up. Plus, I wanted to check out some of the displays in the museum!

I chatted with the park staff for a good 15 minutes or so. They were incredibly kind and very familiar with POTA (of course). They were especially familiar with my buddy Max (WG4Z) who lives nearby and activates the site frequently. He’s evidently been a great POTA ambassador!

Having spent so much time in the visitor’s center, I was only left with 45 minutes to complete my activation from setup to pack-up. Continue reading A Speedy QRP POTA Activation of the President James K. Polk State Historic Site →

KO4WFP: An Unexpected, Speedy Activation at Tuscumbia WMA in Mississippi

9 Comments

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

An Unexpected, Speedy Activation at Tuscumbia WMA in Mississippi

by Teri (KO4WFP)

Some of the best things in life are unexpected.

My family, after spending two days in Dallas, Texas visiting in-laws, headed back east on Wednesday, July 26. We originally planned to drive Interstate 20 through Louisiana and Mississippi with a stop in Alabama to visit with friends. However, early Wednesday morning, I Googled our route and realized a shorter route through Arkansas and Mississippi would save us thirty minutes. That doesn’t sound like much but when you spend nearly all day driving in a car, thirty fewer minutes feels like a big deal.

Before the trip, I planned an activation in and purchased a permit for Louisiana’s Russell Sage WMA (K-4076). Well, now I wouldn’t even go through Louisiana on our way back. I was loathe to not activate a park at all on the drive home. (Those who know me well, know I don’t give up easily at anything.) So I looked at the new route and the POTA website and endeavored to find a park that would work as well as we’d reach later in the day due to the hot weather. I settled on Tuscumbia Wildlife Management Area (K-7092) in Mississippi along US Route 72.

The 2,600 acre Wildlife Management Area (WMA) is located just outside Corinth, Mississippi and divided into two sections, one on either side of US 72. The section to the north of the highway is primarily swamp bottomland but the northeast corner of it is accessible to the public. The WMA is a great place for birding and I noted 104 species have been observed according to the website eBird. It was this northeast corner at which I would attempt my activation.

The weather during the day was hot! At the Arkansas welcome center, I noted the boat-tailed grackles in the parking lot panting to cool off in the heat. I planned to reach Tuscumbia WMA  near the end of the day but whether it would still be too hot or not, I had no idea. Thankfully, as we reached the Mississippi state line out of Memphis, cloud cover appeared and I watched the temperature on the dashboard slowly descend from 99 degrees earlier in the day to a manageable 86 degrees.

The other potential wrinkle in my last-minute decision was whether accessing the park required a fee or not. I couldn’t tell from the Mississippi Department of Wildlife, Fisheries and Parks website. When we reached Memphis and had better cell service, I called one of their offices and spoke to a helpful employee who confirmed that yes, I would need a permit which I could purchase using their app. I also needed to use a second app to check in and out when actually at the park. Somehow I managed to get the apps downloaded, my account set up, and a one-year non-resident permit purchased during my husband’s turn at the wheel. Whew! One more hurdle surmounted.

Everything seemed to be falling into place. The last remaining wildcards were if I would arrive early enough before sunset and would I be able to find a place to set-up.

We arrived at the site a little before 7 PM. The most obvious place to activate, on the gravel pad next to the highway, had power lines running right above it as I had feared. There was no way to set up there. And I could not drive the car further into the property as gates prevented auto access. My only other option, with daylight running out, was to walk into the property, find a spot, and sit on the ground. To make space for our trip luggage, though, I left behind the bin in which I usually keep a tarp and other emergency supplies. (Note to self – next time keep at least a tarp in the car.) The only thing I could find for me to sit on was the windshield sunshade – not ideal but it would work.

I checked into the app, grabbed my POTA backpack, liberally applied bug spray for the gathering mosquitos, and headed past the gate to see with what I had to work. By the way, I’ve never seen mosquitos so large in size! They were at least three times bigger than the ones we have in Savannah, GA.

Sometimes you just need a little radio-active therapy

24 Comments

This has been a busy summer.

In fact, “busy” is an understatement.

We have a number of DIY projects going on at the QTH, I’ve a long list of things I need to fix (this has been the year of everything breaking), we’re scoping out a new PV system, and family life has been at an all-time high in terms of activity.

It’s funny: Matt mentioned in his recent field report that my POTA/SOTA catchphrase is, “I don’t have much time for this activation.”

It’s so true! I say and think that all the time.

My schedule is such that I so rarely have more than one hour tops to spend at a park or on a summit. At this point in my life–being the father of two amazing teenage girls, a husband, and checking in on my sweet parents regularly–my days are packed pretty darn full.

That said, I get a small thrill out of doing fully portable park activations even with a little time pressure. Perhaps it’s because it’s what I’ve gotten used to? Regardless, it’s fun.

My hope, by the way, is to add a bit more camping at parks into the mix this fall so I can spend long relaxing evening sessions on the air. We’ll see if that becomes a reality!

“Radio-Active Therapy”

One thing I know for sure: activating parks and summits is proper radio therapy.

I know I probably sound like a broken record on this point.

Something about hitting the field, deploying an antenna, hopping on the air, and using the “sacred language” (i.e. CW) just takes me away from all of my worries and obligations. It clears my headspace.

I liken it to the same feeling I get when mountain biking. When I mountain bike, I rarely think of anything other than the path in front of me, preparing for roots, rocks, and other things that could otherwise flip me off my bike.

With POTA and SOTA? I listen to the ether, pull out contacts, and connect with friends via magical wireless links. That’s where my mind goes.

After a good ride or a good activation, I feel a million dollars.

Tuttle Educational State Forest (K-4861)

The days leading up to Wednesday, July 12, 2023, had been particularly hectic; I was in need of some proper radio-active therapy, so I stopped by one of my favorite spots–Tuttle Educational State Forest–for a little POTA. Continue reading Sometimes you just need a little radio-active therapy →

Matt’s Summer Vacation Mountain POTA

9 Comments

Many thanks to Matt (W6CSN) who shares the following post  from his blog at W6CSN.Blog:

Summer Vacation Mountain POTA

by Matt (W6CSN)

Our family regularly enjoys a summer vacation in the mountains. There is no shortage of mountains along the Pacific Coast, but if you refer to “The Mountains” around our house everybody knows you are talking about 5500 feet up the western slopes of the Sierra Nevada along Highway 4 near the town of Arnold.

Summer Cabin

Last year’s trip to “the mountains” was my first foray into portable QRP operating and I successfully hunted a few Parks On The Air stations. In the year since, I’ve become much more involved with (some would say addicted to) POTA, especially as an activator.

The cabin sits on a small lake.

For the “base” operation of hunting other stations, I set up the FT-818 with an EFHW strung between the deck and some trees adjacent the nearby lake. The 26 ga polystealth wire antenna literally disappeared into the trees, the only giveaways being the 64:1 transformer floating in space off the deck rail and, more likely, the the bright orange arborist line used for the downhaul at the far end.

I made a few hunter QSOs during the morning hours from the cabin, but this location wasn’t hearing particularly well. Signals weren’t strong and I sent more than a few 229 reports. However, this “hunter mode”operation was secondary to my main objective of activating some new to me parks while on this trip.

Hunter QSOs from the cabin

On the first full day in the mountains we headed back down the hill a ways to visit Railtown State Historic Park in Jamestown, CA. After riding the excursion train and enjoying lunch by the roundhouse, I brought up the possibility of an activation. However, with the July heat well into the triple digits, the family wasn’t in the mood for dads radio obsession. Quite frankly, I wasn’t too excited about setting up the station in the heat, so it was an easy choice to put this one off for another time.

No activation attempt at Railtown this time

The next POTA activation opportunity came when we had made plans to head up for a day at Lake Alpine. We chose to go up to the lake around 10AM on Monday, hoping for smaller crowds. Also, we had plans to visit Calaveras Big Trees SP the following day.

This gave me an idea: I could make the short drive from the cabin up to Calaveras Big Trees (K-1134) in the morning while everyone was sleeping in and try to get the activation done before heading to Lake Alpine. This way the family visit to Big Trees wouldn’t be interrupted by dad playing radio. Continue reading Matt’s Summer Vacation Mountain POTA →

KO4WFP: Braving the Heat at Spring Creek Forest Preserve in Texas

6 Comments

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

Braving the Heat at Spring Creek Forest Preserve in Texas

by Teri (KO4WFP)

The last week of July, my family and I visited my husband’s sister and brother-in-law who live in the Dallas, Texas area. Of course, as soon as the decision was made to make the trip, I immediately checked to see if there were any POTA sites nearby. And wouldn’t you know, there is one roughly 12 miles away – Spring Creek Forest Preserve (K-4423). This would be my chance to activate my first Texas park.

Spring Creek Forest Preserve is a city-owned nature preserve in Garland, Texas. The forest contains old growth trees and several rare and unique plants. Seven miles (four dirt and three paved) of trails traverse the property. The park is named for the creek that runs through it. Today, the creek was deceptively quiet and the water level low. However, given the sculpted chalk cliffs that run above the creek and the flood stage signage, the waterway obviously has its wilder moments.

The morning of July 25th, I headed out early for the easy forty-minute drive from my in-laws to the preserve. The weather forecast predicted a high of 101 degrees, easy to imagine as by the time I arrived at the park, around 8 AM, the temperature was already 80 degrees.

I scoped out the parking lot. It was mostly empty on this day. Having no idea how busy the park might become, I looked for a place less likely for people to encounter my antenna. At first I chose a tree on the edge of the parking lot. However, there was nowhere to park my car close by and I wanted to sit inside the car during the activation.

In the middle of the circular parking lot was a tree surrounded by weedy growth. I figured no one would choose to wander through those weeds and thus my antenna would be safe and not need to be flagged.

I soon discovered why no one would want to wander through the weeds – they were full of little oval-shaped stickers! Thankfully they didn’t have long needle-like spikes on them and instead of being painful, were just annoying. They ended up all over my socks, shoelaces, and the hem of my shorts.

It took several tries to get my arbor line successfully in the tree as its branches were mostly aimed upward rather than outward. But on the third throw, I successfully snagged a branch of sufficient height for my EFRW antenna to slope toward my car. Just as it took several tries to snag the right branch, it took several adjustments to get the right amount of tension in the antenna. Rather than retie the arbor line every time I adjusted it, I just tied another slip knot and as such it ended up looking a mess. But I finally got the amount of tension and height I wanted. (By the way, the weeds made for a mess untangling my arbor line after the activation, too!) Continue reading KO4WFP: Braving the Heat at Spring Creek Forest Preserve in Texas →

Getting To Know You Series: The Icom IC-705 – My thoughts, notes, and a POTA activation!

16 Comments

I’m very fortunate in that over the past few years I’ve accumulated 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 over the years. In those reviews, I try to take a wide angle view of a radio–I try to see how it might appeal to a number of types of operators: field operators, DXers, summit activators, contesters, rag-chewers, casual operators, SWLs, travelers, outdoor adventurers, mobile operators, etc. 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.

On that note, I thought it might be fun to take a radio out for a field activation and spend a bit of time explaining why I enjoy using that particular radio and why it’s a part of my permanent field radio collection. Instead of taking that wide-angle view of a radio like I do in magazine reviews, I share my own personal thoughts based on long-term experience.

Getting To Know You

Each new video in the Getting To Know You series will highlight one of the field radios from my field radio collection.  I’ll spend time in each video explaining what I personally appreciate about each radio, then we’ll do a park or summit activation with the radio.

I’ll release these every few weeks or so–when the notion strikes me.  They will not be on a regular schedule, but I hope to include each of my radios in this series over the the next year.

The Icom IC-705

The second radio in the Getting To Know You series is my Icom IC-705.

From the moment I first unboxed my Icom IC-705, I’ve been incredibly pleased with it. It’s a proper 21st century radio. Not only does it have a very wide frequency range, multimode operation, and an incredibly deep feature set, but it also sports proper wireless connectivity.

The IC-705 has become one of the most popular QRP rigs on the market despite it’s nearly $1,400 US price tag.

I originally purchased and reviewed the Icom IC-705 in 2020 (click here to read my review).

In the activation video (below) I’ll tell you about how I acquired my IC-705, why I think it’s so unique, and why I’ve no intention of ever selling it. Then, we’ll perform a POTA activation.

Keep in mind that my perspective will primarily focus on HF operating even though the IC-705 also sports multimode VHF and UHF.

South Mountains State Park (K-2753)

While driving back to the QTH on July 6, 2023, I stopped by the Clear Creek Access of South Mountains State Park–it was the perfect location to play radio on a hot and very humid day.

South Mountains’ only picnic table is located under the shade of a large oak tree. Continue reading Getting To Know You Series: The Icom IC-705 – My thoughts, notes, and a POTA activation! →

Field Report: Testing the bhi Dual In-Line with the (tr)uSDX, making a big blunder, and P2P with Teri!

10 Comments

On March 30, 2022, I took my factory-assembled (tr)uSDX transceiver on a POTA activation at South Mountains State Park.

It was a “test flight” of sorts since I’d only had the (tr)uSDX for a few days and had not taken it to the field.

I wrote up an assessment from that initial POTA activation mainly to give other potential (tr)uSDX owners an idea of how well one of these super-affordable radios might perform.

Difficult to critique

It’s difficult to critique a 5 band HF radio that you can purchase as a kit for less than $100 and fully-assembled and tested for less than $150…shipped!

On the one hand, I think it’s one of the most amazing portable HF radio innovations of the past decade. It simply blows my mind that the developers (DL2MAN and PE1NNZ) could make this modest radio hardware do so very much. It’s truly a triumph of engineering and a fun little radio.

On the other hand, this isn’t a high-end radio, so we can’t expect performance like we’d see in an Elecraft, Icom, or Yaesu field radio, for example. I never expected this, in fact, but was very curious if the performance would be “good enough” for POTA or SOTA.  So many had asked me about buying a (tr)uSDX as their dedicated POTA radio.

I found using the (tr)uSDX for POTA was actually quite fun, and I certainly achieved my goal of activating a POTA park with it.

So yes, it’s good enough!

That said, I haven’t reached for the (tr)uSDX to do POTA or SOTA since last March because I prefer the performance characteristics of my other radios.

My biggest complaint, frankly, is that the audio fidelity is pretty poor. The noise floor of the (tr)uSDX is higher than most HF radios and audio amplification is very basic. I notice a lot of electronic noises (pulsing, etc.) in my unit. I find it a bit fatiguing to listen to for long sessions with my headphones. The internal speaker isn’t really a viable speaker for doing an activation–it’s more akin to an emergency speaker, if anything.

When plugged into an external amplified speaker, the audio is much improved. The pops and internal noises are still there, but it has better overall fidelity and the volume can be raised enough to hear weak signals (this can’t be easily done via the internal speaker).

It struck me that a DSP device might clean up the (tr)uSDX’s audio and noise floor a bit.

Enter the bhi Dual In-Line DSP filter

Sometime during the beginning of the pandemic, I reached out to bhi Noise Cancelling Products and asked if I could test one of their DSP units as a loaner. I’ve always felt that bhi manufactured the best DSP products in the amateur radio market.

At the time, I wanted one of my friends and contributors on the SWLing Post blog to test the bhi unit and see if it might help out a QRM situation that popped up at his QTH. I thought it would make for a great evaluation since I have little to no QRM at my home.

Graham, at bhi, kindly sent me a unit–the Dual In-Line Noise Eliminating Module–and as I prepared to forward it to my friend, his noise was no longer an issue. I can’t remember the details now, but there was no need to send it to him.

I notified Graham that I would like to test it myself, but that my plate was so full it would take time. What ended up happening, though, was I completely forgot about it due to a busy family life at the time.

I re-discovered the unit this year and spoke (apologized) to Graham at the 2023 Hamvention. Of course, he had no issue at all and was very forgiving. He’s a great fellow.

I thought pairing this bhi DSP unit to the (tr)uSDX would be a great way to, perhaps, cut down on the listening fatigue.

Fort Dobbs State Historic Site (K-6839)

On Wednesday, July 5, 2023, I had an opportunity to test the (tr)uSDX/bhi pairing at Fort Dobbs State Park. Continue reading Field Report: Testing the bhi Dual In-Line with the (tr)uSDX, making a big blunder, and P2P with Teri! →
