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.

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!

3 Comments

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

2 Comments

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

3 Comments

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.

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 →

K3ES’ Hike with Molly: The POTA Dog In-Training!

“Hey!  I can be a POTA Dog.  Let’s go on a hike!”

A Hike (and Activation) with a POTA Dog In-Training

by Brian (K3ES)

PA State Route 66 Trail-head on K-4239

A plan for a Hike and an Activation

A couple of Wednesdays ago, I decided to take a hike along the North Country Trail.  It would not only provide some needed exercise on a beautiful day, but it would also take me into Pennsylvania Game Land #024, enabling a 2-fer activation of K-4239 and K-8725.  I had hiked this stretch of the trail several times before, so I figured it would be safe taking one of our dogs along for the trip.

Jojo (front) and Molly (back) are not happy about this staged picture.

Molly and Jojo are two rescued Boston Terriers, who have made our home their own since October of last year.  Each has her own character.  Molly is exuberant, very friendly, and frankly, a bit of a bulldozer.  Jojo is pure sun bunny, preferring to find a bright patch of lawn, then lay there soaking up the heat.  Once installed in a sunny spot, Jojo doesn’t like to move.  So, it seemed natural to invite Molly along for the afternoon hike.  The only potential issue was the planned stop for a park activation.  I was almost certain that Molly would enjoy the walk, but how would she handle the period of inactivity?  There was only one way to find out.

Jojo in her natural habitat:  sunbathing in the back yard.
Molly on the run.

Since solar conditions had been keeping the radio bands rough and unpredictable, I decided to start my QRP CW activation in the middle of the afternoon.  Beginning the activation at 3pm EDT meant that my first hour would overlap with the popular CWT sprint, so I planned to start on the 30m band to avoid trying to compete with my 5 watt signal.  More importantly, the timing would let me finish on the 40m band later in the afternoon, when I have always found it to be productive.

Molly supervises CW operations during the 2-fer Activation.

The plan was set and an activation was scheduled in POTA.app to begin at 3pm EDT, so detection by the Reverse Beacon Network (RBN) would assure automatic spotting.  We left home just after 1pm, drove to the trail head, and started our hike to the activation point.  Our travel and the station setup went quicker than expected.  Even after securing Molly on her leash, with space to move around and drinking water in reach, all was ready to begin by 2:30pm.  Fortunately, there was sufficient cell coverage to let me directly enter an early spot.  Despite the early start, I stayed with my original plan to begin on the 30m band.

Activation

Contacts on 30m came slowly, but I was able to confirm the activation with 11 contacts in just over an hour.  Since the CWT sprint was continuing, I moved over to 17m to see if I could pick up some more distant contacts, but it was not to be.  I heard one strong signal on 17m – calling CQ over me.  I am confident that the operator did not hear me on the frequency, particularly since he did not pick up my call when I responded to his CQ.  Not only that, but my 5 watt signal did not even manage to attract the notice of the RBN.  I took that episode as a sign that it was time to QSY.

Logs from the activation filled up the last 2 pages of one notebook, and the first page of a second notebook.

Since it was past 4pm EDT, and the CWT sprint was finished, I moved over to 20m. Continue reading K3ES’ Hike with Molly: The POTA Dog In-Training! →

Travelogue and Field Report: POTA and Aviation Geekery with Friends in Dayton, Ohio!

3 Comments

A couple months ago, my good friend, Monty, hatched a plan to take his father to the National Museum of the U.S. Air Force in Dayton, Ohio.

I thought it was a brilliant idea. Monty’s dad, John, served in the US Air Force in the 1960s and has always been a fan of aviation. Despite this, he had never been to the USAF museum.

Monty and I have been friends since being roommates back in our undergraduate years; he and his parents are like family to me. (You might remember Monty from a couple of SOTA/POTA activations in the past.)

When Monty asked, “Hey, would you like to join us–?” It took me all of one microsecond to say, “Heck yeah!”

Off we go…

Monty, John, and I hopped in the car and headed to Dayton (from Charlotte, NC) Sunday morning, July 16, 2023.

It was a beautiful day for a 7+ hour road trip, too. Of course, I made sure we timed the trip so that we could stop at Tamarack in Beckley, WV for lunch.

We arrived at our little AirBnB vacation rental late that afternoon.

The house was literally a stone’s throw from the USAF museum. If we would have been any closer, we would have been on the museum driveway.

USAF Museum

Monday morning (July 17) we ate breakfast, then made our way across the road to the museum shortly after they opened the doors at 9:00.

I’ve been to the USAF museum at least fifteen times and it never gets old.

It’s the largest military aviation museum in the world and it’s brilliantly curated. They’re always shuffling around exhibits so that even if you visit annually, you’ll always find something new and fascinating.

The one and only Memphis Belle.

Without a doubt, my favorite part of the museum is the WWII Gallery because I’m such a huge history buff of that era.

Then again, I love the modern stuff, too, and the USAF museum certainly serves it up. Continue reading Travelogue and Field Report: POTA and Aviation Geekery with Friends in Dayton, Ohio! →

Bob’s three day POTA camping trip in and around the Dismal Swamp!

8 Comments

Many thanks to Bob (K4RLC) who shares the following POTA field report from February 2023:

Dismal Swamp Activation – February 2023

by Bob (K4RLC)

The Dismal Swamp is a lovely place !

The goal for this winter was to activate the Dismal Swamp in northeastern North Carolina, both as it is a relatively rare area, and during the summer it is full of critters like snakes, gators, bears, and mosquitoes as big as birds. So, in February I did a three day trip.

First, I activated the Dismal Swamp State Park (K-2727) in Camden County North Carolina, off US Highway 17.

This  state park contains some  historically important lands to the US. In pre-revolutionary times, George Washington actually bought some of the swamp land  and attempted to drain it to make it farmland. His plan failed, but there is still a marker for his house on the Virginia side. Indigenous people lived here 13,000 years ago, and flourished off the rich fish and animal life.

During the Civil War, the Dismal Swamp was an important part of the Underground Railroad, for those escaping from slavery in the South to freedom in the North. Some slaves used ancient Indian villages as the foundation for building communities deep in the swamp. There are still remnants of this rich history. Originally, the Great Dismal was over a million acres, but now is only half that size.

To make this activation more interesting, you first must go to the Gate Keeper and sign in with your name and give the model and color of your car before you can enter the park. This is to keep track of lost souls who might wander off the path in the swamp, never to be found.

The Gate Keeper also controls the bridge over the Dismal Swamp Canal, which is part of the Intercoastal Waterway up the East Coast of the United States, sometimes called a water way Interstate. This canal was also historically important for transporting materials in the 1800s.

During World War II, when German U-Boats torpedoed merchant ships off the coast of North Carolina, the Dismal Swamp Canal became an important waterway for military transport.  Once you enter Dismal Swamp State Park, there are several hiking trails along the Canal and back into the Swamp. One even takes you by a Moonshine Still which unfortunately was not still operating.

I set up the trusty ICOM-706 MkIIG at a picnic table on 20 meters CW, and soon had a nice pile up going. Someone spotted me on the POTA site and RBN. Soon, I was getting emails to my cell phone asking for contacts. Little did I know how rare Camden  County was,  especially on the 40 and 20 CW bands.

I wish I had had more time to explore Dismal Swamp State Park, including walking the 20 mile path along the Canal, but I wanted to go to the Dismal Swamp National Wildlife Refuge (K-0566) which was over an hour’s drive away, with the entrance across the border in Virginia.

On the way, I got an email from a ham in Hungary who needed a nearby county on 20 meters CW – Pasquotank County. Since it was only a bit out-of-the-way, I thought the least I could do was to drive there and help an overseas fellow ham.

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.
