Exploring the Mountains-to-Sea Trail: QRP POTA with Hazel and a New KX1 Kneeboard!

11 Comments

On Friday, January 5, 2024, I looked at Hazel and could tell that, despite the chilly temps, she wanted to go on a late afternoon hike. I did, too, for that matter and why not combine the hike with a POTA activation?

In addition, we were expecting a winter storm to move in that night, so hitting the trail in advance of the snow and ice seemed to make sense.

Before I could get my boots on, Hazel was waiting by the car door to jump in.

Mountains-to-Sea State Trail (K-8313)

One of the closest long trails near my QTH is the Mountains-to-Sea Trail (MST).

At 1175 miles long, the MST stretches from the Outer Banks of North Carolina to the Great Smoky Mountains (see map above).

I can actually hike to the MST from my QTH, but it takes a good hour and half to do so. It’s much easier to drive to one of the numerous nearby trailheads, and that’s exactly what Hazel and I did. I drove to one of my favorite Blue Ridge Parkway POTA spots where a short manway connects to the MST.

Hazel was so excited to hit the trail. (I was, too.)

At the end of the day (because, it was nearing the end of the day) we couldn’t hike for long if I planned to also complete a POTA activation. Sunset was at 5:29 PM local and I didn’t want to pack up and hike back in the dark.

That said, if I needed to hike back in the dark, I could have because I never go on a POTA or SOTA activation without a fully-charged headlamp. FYI: I was packing a NiteCore NU25 (affiliate link).

I started my action camera and captured the last bit of hike before Hazel and I found a great spot to set up. There were enough trees around to deploy a 40 meter EFHW and a relatively flat spot to set up my Helinox chair and KX1 station.

Since much of this section of the MST is on the Blue Ridge Parkway grounds, I checked quickly to make sure my operating site would qualify as a two-fer with K-3378.

I opened the Parceled App on my iPhone to confirm that my site was indeed on Blue Ridge Parkway property..

A KX1 Kneeboard!

If I’m being perfectly honest, I had an ulterior motive with this trailside activation: I was eager to finally put my new KX1 kneeboard into use! Continue reading Exploring the Mountains-to-Sea Trail: QRP POTA with Hazel and a New KX1 Kneeboard! →

Weekend POTA Roundup

by Matt (W6CSN)

It’s been a stormy past several days here in Northern California, but if anything, the weather only amplifies my motivation to go outside and get on the air.

Rather than do a separate writeup for each, this post is a roundup of my last four POTA activations, from Friday, February 2nd through Sunday, the 4th.

A faint rainbow splashes down in front of Angel Island

Thursday and Friday had been wet, with one storm in a series moving across the Bay Area. However, by Friday evening the cold front had passed and there was a break in the rain. This was a perfect opportunity to try an after work activation at the Presidio of SF (K-7889).

I hadn’t used the QCX-Mini in a while, and this activation reminded me why. I believe what is happening is that being so close to the antenna, RF interference causes clicking while keying, nearly to the point of distraction. I need to experiment with RF chokes on the key and audio lines to see if that improves the situation.

Fed up with the RFI on the QCX-Mini, I switched over to the MTR-4B which doesn’t seem to suffer the same issue. I wrapped up the activation after netting 21 QSOs in the cold west wind.

All QSO maps in this post are from http://tools.adventureradio.de/analyzer/

The next bout of rain wasn’t due to arrive until later Saturday afternoon. This was a change in the forecast that subsequently altered my plan to stay in Saturday soldering on my QMX Hi-Bander project.

Initially I went to Fort Point (K-0819) in the hopes of changing it up from my usual activation park but there were just too many people there. So seeking relief from crowds, I crossed the Golden Gate Bridge and went up on the slopes of Mt. Tamalpais.

I parked at Trojan Point at an elevation of approximately 1800 feet. See this post for more views from this location. The temperature was in the mid-40s, which is cold for us coastal Californians. Besides, the winds were picking up ahead of the next storm so I operated from the comfort of my vehicle using the Gabil 7350T base loaded vertical antenna on 15m and 20m.

This activation used the FT-818 and yielded 23 contacts, including JH1MXV from northwest of Tokyo, Japan coming in fairly strong on 21 MHz.

Driving back to San Francisco takes me right through the Presidio of SF (K-7889) and noticing that it was after 00:00 UTC, I made the last second decision to divert to East Beach to see if I could work in another activation before the anticipated rain.

At my usual spot for activating this park, it took only moments to raise the MFJ-1979 20m quarter wave and do a quick deployment of the MTR-4B on the trunk of the car. The wind was picking up, but not nearly as strong as it was up on the mountain.

After seven QSOs, the skies began spitting raindrops, this was going to be close! I closed the cover of the Maxpedition pouch to protect the radio and battery while the Bencher paddles could tolerate a little bit of moisture.

I was happy to have a Rite-In-The-Rain notepad for logging [Amazon affiliate link], because now I was certainly writing in the rain! Three more contacts and the activation was concluded with a hunt of Jim, WB0RLJ, in K-4011. Continue reading Matt’s Weekend POTA Roundup! →

Washington, DC Field Report

By: Conrad Trautmann, N2YCH

January 30, 2024

Periodically, I travel to Washington, DC for my job. On my latest trip, I carved out some time to activate some parks. The hotel I was staying at is just a few minutes away from the National Mall, which provides many activation options on the POTA website. After scoping it out on Google Earth and researching trails using the National Parks mobile app and web sites, I settled on the Jefferson Memorial, K-0792 as my first stop which is a two-fer with the National Mall, K-0655.

Just steps away is the George Mason Memorial where the Potomac Heritage Trail National Scenic Trail, K-4564 passes right through and is located along the East bank of the Lower Potomac River. The Captain John Smith Chesapeake National Historic Trail, K-4567 runs by as well. The bench I found on the shore of the river met the minimum 100’ rule for both trails and was also located in the National Mall park, so this location was a three-fer.

I tried to travel as light as possible this trip. The gear I chose to bring was the Elecraft KX2 along with the AX1 antenna and my laptop with the USB sound card and CIV cable.

The January winter weather was mild, in the low 40’s F so setting up and activating outside wasn’t a problem. With it being off season for tourists, I had the park almost all to myself.  There were signs posted at the memorial asking visitors to be quiet and respectful, so the last thing I wanted to do was set up on the steps and draw attention to myself. I found a wall near the Tidal Basin’s water’s edge and was able to set up out of the way of anyone wanting to photograph the memorial, but still be on the property.

Late-Shift 80 Meter Activation Tonight

9 Comments

I normally don’t announce activations on QRPer, but tonight I plan to activate a two-fer of Pisgah National Forest (K-4510) and Pisgah Game Land (K-6937) starting roughly around the turn of the UTC day (19:00 EST tonight, or 00:00 UTC on Februay 7, 2024).

I’ll be testing an 80 meter coil for the Chelegance MC-750 vertical.

I’m announcing this POTA activation becase a number of you who live way too close for a 40 meter and up contact have asked me to post if I plan a late night activation on 80 meters.

I hope to put you in the logs!

Cheers,

Thomas (K4SWL)

A Hasty Activation in Georgia

4 Comments

by Teri (KO4WFP)

As many of you know, my personal life has been tumultuous these past five months. I thought maybe it would settle down after the first of this year but no such luck. My son and I moved into a townhouse the third week of January. While I appreciate my parents upending their lives to accommodate the two of us during my divorce, there were too many people in too small of a house with too much stuff. Also, my son needed a room of his own which he didn’t have at their place.

Moves are never convenient and this one was no exception. I needed to be packing the Sunday prior to my early Monday morning move. However, I had already committed to and scheduled an activation at Oliver Bridge Wildlife Management Area (K-3764). The weekend of January 20th and 21st was the winter Support Your Parks weekend and, as a POTA Babe, there was no way I would miss the event!

Support Your Parks information on POTA website

Thankfully, Oliver Bridge Wildlife Management Area (WMA) is only 40 minutes from my parents’ home. That meant another pleasant drive in rural Georgia on GA Route 17 through the communities of Guyton, Egypt, and Oliver.

Google Maps

This WMA consists of 1,560 acres and offers hunting for deer, small game, and turkey. Checking the Georgia Department of Natural Resources Hunting Regulations guide, the only item in season this particular weekend was small game. I would make sure to take the blaze orange vests for both Daisy and me again.

The WMA is bounded on one side by the Ogeechee River, one of the few free-flowing streams in Georgia. This blackwater river runs southeast 294 miles to empty into the Atlantic Ocean at Ossabaw Sound near Savannah. It played an important part for trade and commerce as well as was a source of freshwater and food for communities along its banks. In present day, kayaking and canoeing are popular pastimes on the river as well as fishing.

https://gisgeography.com/georgia-lakes-rivers-map/

Daisy and I arrived at the WMA a little before 11 AM. We took River Road in the park to find a place for the activation. The road was in rough condition in some spots and was another one I’d not want to drive immediately after a heavy rain. I was thankful, once again, for my four-wheel drive Subaru Crosstrek nicknamed Kai. (My family has a funny habit of naming all our cars.)

On the map, there appeared to be a clearing about two-thirds of the way down the road. Tall, skinny pine trees lined either side of the road, not great for getting an arborist line into them. Thankfully, the canopy opened up for a small clearing as I surmised from the map and it was here I decided to set up.

Because of the opening, the pine trees near the side of the road had some lower, reachable branches on them. After a few tries, I snagged the branch I wanted and began hoisting the Tufteln EFRW antenna with the arborist line.

In past activations, I would usually get the antenna up however I could. But, at this point in my POTA journey, I am beginning to think how I want the antenna oriented with propagation in mind. I wanted it to run at a diagonal – northwest to southeast. To do that, I’d have to get it across a wide ditch that was partially frozen due to the cold temps. However, if I just tossed the line across, it was light enough it would likely end up in the ditch where I couldn’t easily retrieve it. Continue reading A Hasty Activation in Georgia →

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

4 Comments

The other day, I was thinking…

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

It’s a little insane, really.

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

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

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

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

I was right!

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

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

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

Speaking of which…

Tuttle Educational State Forest (K-4861)

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

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

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

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

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

First, a quick inventory…

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

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

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

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

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

On The Air

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

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

Proper QRO: K4RLC Tours The Edward R. Murrow Transmitting Station

Many thank to Bob (K4RLC) who shares the following guest post:

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

by Bob (K4RLC)

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

[Note: Click on images to enlarge.]

VOA QSL Card showing some of the 38 antennas

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

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

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

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

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

W7UDT: “Velcro, ergo; ergonomics…”

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

Velcro, ergo; ergonomics…

by Rand (W7UDT)

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

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

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

Here’s the old QDX kit…

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

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

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

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

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

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

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

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

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

4 Comments

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

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

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

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

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

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

Gear:

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

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

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

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

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

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

Here’s Jonathan’s QSO Map:

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

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

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

Here’s my QSO Map:

Activation Video

Here’s our real-time, real-life video of the entire activation.  As with all of my videos, I don’t edit out any parts of the on-air activation time. In addition, I have monetization turned off on YouTube, although that doesn’t stop them from inserting ads before and after my videos.

Note that Patreon supporters can watch and even download this video 100% ad-free through Vimeo on my Patreon page:

POTA Meetups

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

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

Thank you!

Thank you for joining us on this joint activation!

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

Of course, I’d also like to send a special thanks to those of you who have been supporting the site and channel through Patreon and the Coffee Fund. While certainly not a requirement as my content will always be free, I really appreciate the support.

As I mentioned before, the Patreon platform connected to Vimeo make it possible for me to share videos that are not only 100% ad-free, but also downloadable for offline viewing. The Vimeo account also serves as a third backup for my video files.

Thanks for spending part of your day with me! Have an amazing weekend!

Cheers & 72,

Thomas (K4SWL)

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

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