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

3 Comments

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.

South Mountains State Park (K-2753)

 

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.

ABR Industries 10% Discount Code for QRPer.com Readers!

6 Comments

Many of you know that I’m a big fan of cable assemblies from ABR Industries. I’ve been a customer of theirs for well over a decade and I’ve never had one of their cables fail me.

I’ve hinted to ABR in the past that it would be great to have a sponsorship or affiliate relationship with them.

ABR came through this week by starting an affiliate program with QRPer.com and will give our community a 10% discount on any items purchased on the ABR website via our link and by using the discount code:  ABR10QRPER

I made a few suggestions of cable assembly types and standard lengths based on the ones I use the most and I feel others would find useful in the field. They created a page specifically for these options and the selection will likely grow with time:

Click here to check out the options.

Chuck, at ABR, notes:

“it’s important to use the 10% discount code under ABR10QRPER. It’s in the checkout section under coupon. The reason is if a customer buys other items they will enjoy the discount beyond these focused products.”

So there you go!

If you need something other than what is listed in this selection, ABR will help you find what you want on their website–just make sure you enter the coupon code for the discount!

Many thanks to ABR for setting up this affiliate relationship and discount code. You may note that I only have affiliate relationships with companies I trust and patronize myself. Very proud to have ABR on board with QRPer.com!

Best QRP field transceivers for operators who are blind/visually-impaired?

8 Comments

I recently received the following inquiry from Vic (K7HSS) who shared that he is blind and seeking a field-portable transceiver that is user-friendly to those who are visually impaired. 

Vic notes:

I’ve actually owned the KX2 before, but it was now sold, because I realize that I was sitting on a lot of money, and I wasn’t doing that much portable operations at the time.

The KX line is ideal because it has CW read outs. Having said that, I will be able to make do if a radio somehow stops or notifies me at band edges. From there, I could put some sort of markers on the knob, so that I could roughly gage where I am base on how many spins I’ve given the knob. I’m not very sure how the single band radios like the QCX mini operates. Does it stop once you reach the band edge?

Anyways, those are some thoughts that I have. Also, I’ve been following your Youtube channel and blog for quite a while and is definitely a fan.

I hope you will have a lovely day.

Best and 73,

Vic (K7HSS)

Thank you for the kind words, Vic. 

I’m not visually-impaired so feel like I can’t really comment here, but I do know of at least two other hams who are completely blind and use the Elecraft KX3. From what I gather, it is loved for the CW read outs (as you mentioned) and for there being a dedicated tactile button and/or knob for most of the important functions and features one would use in the field.  

Vic would welcome your comments especially if you are visually-impaired or if you can provide insight about radios with features (like band edge notification) that make it more accessible.  Click here to comment!

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

2 Comments

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

2 Comments

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

2 Comments

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 →

Fred’s simple hack to secure the Begali Traveler

7 Comments

Many thanks to Fred (KE8TBM) who writes:

Here is a solution I came up with for the slipping issue with the Begali Traveler.

It’s very easy to push a pin through the (front only) plastic/rubber feet on the key. This will stop it from sliding on everything including formica counter tops.

After you push the pin through the plastic/rubber feet using a needle nose pliers, simply snip the sharp end off to leave it blunt.

You can leave the little ball on the other end of the pin to retract it if you wish, however, I’ve found that not to be necessary. —-I find that the pins really don’t snag on anything as they just barely peak out the bottom of the foot, but the option is there.

This makes for a rock solid hold on your surface and is a game changer. It’s so nice to be able to push away and not worry about the key slipping around.

Mike, K8MRD just did a review on the Traveler Lite and mentioned the slippage issue.

Best 73 Thomas and thank you for being a great image for the ham community.

Fred, KE8TBM

What a simple and effective idea! Thanks for sharing this tip with us, Fred. Also, thank you for the kind words, OM.

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! →

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.
