Pairing the Yaesu FT-817ND and Chelegance MC-750 at South Mountains State Park

After completing a lively little POTA activation at Lake James State Park (K-2723) and then Table Rock Fish Hatchery (K-8012) on the morning of Monday, July 31, 2023, I decided to squeeze in one more POTA adventure on what became a mini rove.

Since nearby Tuttle Educational State Forest is closed on Mondays in the summer, I chose to visit South Mountains State Park (K-2753) instead–it was only a few minutes further afield than Tuttle.

After leaving Table Rock, I picked up a quick lunch in Morganton and drove to the main entrance of South Mountains and set up at the equestrian picnic area.

The weather that day was beautiful and so was the drive.

I decided to deploy my Chelegance MC-750 this time, just to shake things up a bit. If you know me, when I do little roves like this, I typically like to use different radios and/or antennas at each site.

I paired the MC-750 with my Yaesu FT-817ND. My reasoning for picking the ‘817 was because I could use the SO-239 connection on the back of the radio. The new cable assembly/feedline I was using had PL-259s on each end.

Speaking of the new assembly, at the Dayton Hamvention this year, I popped by the ABR Industries booth and Chuck gave me (full disclosure–at no cost to me) a new product to test in the field: a 20 foot PL-259 to PL-259 assembly made with their ABR240-UF cable and with 5 in-line ferrites. What makes this cable unique is that it sports a bright orange flexible webbed jacketing which makes it very easy to see on the ground.

They’ve been informally calling it their “POTA cable.” I immediately knew why this would appeal to POTA ops: one of my constant fears is that someone will unknowingly trip on my feedline while I’m in the middle of an activation. Black coax cable on the ground is very difficult to see (I’ve even tripped on my own lines)–this high visibility jacketing makes cable very conspicuous. Just check out the photos above.

POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

After a fun little activation of Lake James State Park (K-2723) on the morning of Monday, July 31, 2023, I decided to fit in at least one more POTA adventure on a mini rove.

The logical choice was Table Rock Fish Hatchery since it’s such a short drive from Lake James and I always enjoy activating that particular site.

The weather that morning was beautiful and so was the drive.

Table Rock Fish Hatchery (K-8012)

I pulled into the driveway of the picnic area and–no surprise here–I had the place to myself.

In fact, according to the POTA website, I’ve activated this site 12 times and I’ve never seen another soul in the picnic area save my canine friends, park staff, and one guy who was hunting muskrats in the creek. That’s about it. Never anyone actually hanging around the picnic area.

On the drive over, I hadn’t considered what antenna or radio to use–I had a few in the back of my car.

I thought about using my Elecraft KX1, but then realized I didn’t have an extra shielded audio cable to connect to my Anker Soundcore Mini speaker nor did I have my in-line digital audio recorder. Without those things, I wouldn’t be able to make a video of the activation.

My next choice was the Yaesu FT-817ND and, in fact, it would be ideal. I was looking forward to putting the ‘817 on the air again–it’d been a couple of months!

First, though, an antenna. I pulled out the 40 M End-Fed Half-Wave Steve (MW0SAW) made for me some time ago.

This antenna has been in heavy rotation lately because it’s been in my main radio backpack as I’ve been traveling around the region.

I deployed the EFHW in short order, then hooked it up to the ‘817. Continue reading POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

K4RLC’s December 2022 Adventure at Stone Mountain State Park

Many thanks to Bob (K4RLC) who shares the following POTA field report from December 2022:


K4RLC’s December 2022 Adventure: Stone Mountain State Park North Carolina

by Bob (K4RLC)

As 2022 was coming to an end, I wanted one last Summits on the Air/Parks on the Air (SOTA/POTA) activation. Stone Mountain North Carolina is around 3 hours away in Northwestern North Carolina, near the Appalachian Trail and the Blue Ridge Parkway. It is a huge state park of over 14,000 acres and some wilderness areas.

A little background about this year might be helpful.

Earlier last year, both Alanna K4AAC and I were diagnosed with COVID, which turned into long serious COVID, lasting almost 3 months of acute illness, followed by several months of recovery. We are both healthcare professionals, and were vaxed and boosted and being very cautious, so it’s somewhat of a mystery what happened. One of us does have multiple medical risk factors which may have added to the complexity.

Nevertheless, we did what a lot of Americans did last winter and spring, with buying RVs and campers, and bought a Winnebago Solis camper van.

The Solis is Winnebago’s smallest van, built on a Dodge Pro Master commercial chassis. What appealed to me is that you can be completely self-sufficient, boon-docking with it. It has a 140 Watt solar panel on the roof which charges two 100 amp hour AGM batteries.

Off the grid, this powers a small refrigerator, house LED lights, water pump,  and a ceiling fan.

The Solis also has a 20-gallon propane tank, which runs a two-burner stove and a really nice furnace for cold nights. It sleeps two comfortably with a Murphy bed. Also has a sitting area with a table for dining, which can be used as a desk or an operating position for the radio.

Since getting the Solis, we have really enjoyed making trips to the beaches and mountains of Virginia,  North Carolina and South Carolina. In addition to enjoying exciting POTA/SOTA activations, we have been replenished by nature’s beauty and feeling safe in the fresh air.

Returning to my Stone Mountain adventure, I guess not many people camp in the middle of the week in December in the mountains. Initially, I was the only person in the large campgrounds. Eventually, a couple with their dog and a trailer set up at the far end. We never had any contact. It was really eerie, especially with the pea soup fog that hung around.

The most prominent feature of Stone Mountain State Park is Stone Mountain itself.

It is known as a “Dome Monadnock,” as it is a large dome of granite/quartz still standing from the Devonian Age about 400 million years ago, while the earth around it has eroded over thousands of years. (Stone Mountain Georgia is the same geologic feature). Continue reading K4RLC’s December 2022 Adventure at Stone Mountain State Park

Guest Post: A wildly successful POTA activation…on a whim!

Many thanks to Mike (KE8PTX) who shares the following field report:


One of my best POTA activations on a whim.

by Mike (KE8PTX)

Monday 8/15/2023

Doing some late afternoon POTA chasing from the back deck home QTH,  contacts on 5 watts seemed to be coming fairly easy so I started to think I should have a go at it and activate a park.

One in one hundred times I activate QRO, so I decided to take the FT-891 and blow the dust off the finals.

When filling my pack, I had a last minute change of heart and decided to stick with QRP.  Bagged up the never fail KX2 field kit and hit the road.

The park was Port Huron State Game Land (K-6762) a nearby game land with many activation spots.  As I never do look at the solar reports, this time was no different.  I feel the solar reports more times than not would keep me home. With a QRP mind set we all feel we have something to prove by just doing it.

So off to the park we go!

After a short 20 minute dive through the countryside of the Michigan thumb, I arrived at my location only to be welcomed by a flock of Michigan state birds: the mighty Mosquitoes.  I came prepared with my trusty Thermacell.  Fired it up 5 minutes before exiting the car to give it a head start.

My deployment of gear is simple and quick.  My go-to antenna is a 40m EFHW inverted V configuration running North to South.

My mid support is a modified Carbon 6 mast.

Setup time was less than two minutes and I was on the air. Continue reading Guest Post: A wildly successful POTA activation…on a whim!

Matt’s Low-Profile POTA Activation at the San Francisco Maritime National Historic Park

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


SF Maritime NHP POTA Activation

by Matt (W6CSN)

There are several Parks On The Air eligible parks in San Francisco and the northern tip of the peninsula of the same name. One would expect that a POTA activator that calls this city home, would have logged activations from all of these parks, but so far this one has eluded me.

Muni Pier (closed) across Aquatic Cove

The San Francisco Maritime National Historic Park (K-0757) sits at the northern edge of the city, right next to the Fisherman’s Wharf area that is so popular with tourists visiting San Francisco.

NPS Map of SF Maritime NHP

The National Park encompasses an area that includes the municipal pier, aquatic cove with its small public beach, the art deco style Maritime Museum, and Hyde Street Pier with its floating collection of historic ships.

The historic ships alongside Hyde Street Pier

For various schedule and logistical reasons, K-0757 was the one park in the city that I had not yet activated. So today, when my daughter wanted to visit the ships, I made sure to have my lightweight POTA “go” pack with me in case I found an opportunity to attempt an activation.

I’d say the main attraction at Hyde Street Pier is the Balclutha, a steel hulled, square rigged, cargo ship built near Glasgow, Scotland and launched in 1886.

Balclutha – a survivor from the Age of Sail

Balclutha is continually undergoing restoration and maintenance by the Park Service and skilled volunteers. Her many careers on the world’s oceans are documented with numerous interpretive stations and exhibits, both topside and below decks.

We wrapped up our tour of the vessels on the pier by exploring C.A. Thayer, a 219 foot long sailing schooner built in 1895 near Eureka, California to serve the coastal timber trade.

Eureka is a steam powered ferry that served on SF bay.

I was thinking about where to activate and not really looking forward to setting up on or around the public beach. Between the Aquatic Cove swimmers, people enjoying the beach, and tourists going to and fro, there wasn’t really an “out of the way” location to setup even a small station.

Hyde Street Pier itself was actually pretty quiet, but I wasn’t about to set up my station there without prior approval of park staff. Just as we were about disembark from Thayer I noticed an NPS employee near the gangway, and so I took the opportunity to inquire about setting up my low impact, leave no trace, POTA station.

It turns out the person I talked to on the deck of C.A. Thayer was the supervisor of the SF Maritime National Historic Park! He is keenly interested in radio and was even aware of recent solar activities that have given us amateurs a mixed bag of propagation conditions. He agreed to my request to set up at the end of the pier, past Balclutha’s gangway.

Is Balclutha’s steel hull a reflector of radio waves?

I used the Gabil GRA-3750T antenna with its stock telescopic whip tuned for 20 meters. This is the most low profile antenna I can field for HF. Yes, it’s a compromised antenna system but as you’ll see it works good enough. Continue reading Matt’s Low-Profile POTA Activation at the San Francisco Maritime National Historic Park

POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park!

On Monday morning (July 31, 2023) I left the QTH with POTA on my mind.

As I mentioned in a previous post, July was a busy month and I was in desperate need of some POTA Therapy! Fortunately, I had the full morning to play radio, so I plotted a two (or possibly three) park rove, starting with Lake James State Park.

Lake James State Park (K-2739)

I arrived at Lake James a little after 9:00 AM and pretty much had the park to myself.

In order to keep my setup time a little on the short side, I chose a picnic table next to my car.

I grabbed my throw line cube and (1st gen) Red Oxx Micro Manager pack in which I’d packed my Discovery TX-500 and accessories.

Since it was in the morning, I planned to spend time on the 40 meter band and, hopefully, work a number of hunters in the surrounding states.

For this activation, I paired my Discovery TX-500 with MW0SAW’s 40 meter end-fed half-wave antenna.

I powered the TX-500 with a homemade 5Ah LiPo battery my friend Joshua (N5FY) sent me a couple months ago.

Of course, since I was using a 40 meter end-fed half-wave antenna, I didn’t need an ATU for 40 meters (or 20, 15, or 10 meters for that matter). Continue reading POTA Field Report: A Morning 40 Meter QRP Activation at Lake James State Park!

VE6LK makes a quick trip to Montana o/a AI7LK – Day 2

by Vince (VE6LK)

As you read in day 1 of this story, I landed up in Montana opportunistically. The plan for day 2 was to say goodbye to our visiting family, then make our way north from Kalispell, MT via Eureka, MT and head for home. We’d stop on the way to visit with friends and, of course do one more POTA activation.

Operating position at K-4848. This spot is at the south end of Lower Stillwater Lake.

After departing Kalispell we arrived at Lower Stillwater Lake, part of K-4848, at around 11am MT.

There is one picnic table near a boat launch and it was vacant so I got to work quickly and set up. I had brought along a lightweight kit consisting of my VE6VID EFHW, Elecraft AX-1, the KX3, a battery, a key, a paper logbook and some extra bits like carabiners, a bit of masonry string and a small mast that I landed up not using. With my wife and doggo along for the ride, I didn’t want to take too much time to set up and operate, so the natural choice would have been the Elecraft AX1 antenna, but with conditions being as soft as they were a day earlier, the resonant wire antenna seemed the better choice for the extra 5 minutes it would take to set up.

This short video shows my full set-up:

I looped the feedpoint end around a nearby tree branch and unrolled the antenna and tossed it up in a branch just out of my reach – another low-slung wire antenna! The rest of the gear came out on the table and I used the tote box as a makeshift stand for my shortie camera tripod. Continue reading VE6LK makes a quick trip to Montana o/a AI7LK – Day 2

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

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
