Rough conditions but serious QRP POTA fun at New River State Park

The New River (Photo by K4TLI)

You might recall from my previous field report that I took the family on a camping trip at New River State Park in April 2022.  During that trip, I made an activation of New River each day and also fit in a very fun SOTA activation (click here to read an overview).

Note that anytime you’re performing an activation over multiple days at any one park, you can only have one activation per UTC day.

The following brief field report is essentially my “Part 2” from April 28, 2022. Since I’d already worked well over my ten contacts in the previous activation session that UTC day, all of these contacts were simply icing on the cake!

Keeping this one brief(er)

I’ve an insanely busy day today, what with exam study, errands, splitting firewood, and prep for our summer travels.

That said, I wanted to squeeze in an activation video and field report because the rest of the week is even crazier. Continue reading Rough conditions but serious QRP POTA fun at New River State Park

A comprehensive review of the Penntek TR-35 four band QRP transceiver

The following article originally appeared in the April 2022 issue of The Spectrum Monitor magazine:


“Look at this, Tom! Only the stuff I need and nothing more,” cheerfully noted my good friend and Elmer, Mike (K8RAT).  It was Field Day two decades ago, and Mike was gazing at his TEN-TEC Scout. I glanced over, and agreed. “So simple and so effective,” Mike added.

I’ve never forgotten Mike’s sage words. That Scout (Model 555) was about as simple as a then-modern HF transceiver could be:  it had a total of three knobs––one for AF gain and IF bandwidth, one for RIT and Mic gain, and an encoder. It also had three mechanical switches on the front: one for power, one for TUNE and NB, and one for CW speed and RIT. It also had an analog SWR/power meter. The Scout used plug-in band modules for each HF band and featured a large segmented bright green LED frequency display that was characteristic of so many TEN-TEC rigs of the day.

And Mike was right. For those of us who appreciate radios with a simple, uncluttered, and an almost utilitarian interface, the Scout was, in vintage parlance, “the bee’s knees.”  And that the Scout also performed beautifully was just icing on that cake.

When the Scout first appeared in 1994, embedded menu options and spectrum displays were not yet commonplace among amateur transceivers. Embedded menu items can open the door to near granular level control of your radio’s functionality and features. Then again, if those embedded menus aren’t well thought out, it can lead to awkward operation practices in the field, during a contest, or even during casual operation.

As a radio reviewer, I spend a great deal of time sorting out embedded menu functionality and design. Perhaps it’s for this reason that I so enjoyed reviewing a radio that bucks this trend and reminds me of a time that was simpler, not to mention, easier.

Enter the Penntek TR-35

The new Penntek TR-35 is a four-band CW-only QRP transceiver that is available both as a kit ($279) and as a factory assembled and tested unit ($379). Penntek transceivers are designed and manufactured by John Dillon (WA3RNC).

All of his transceiver kits are available at his website WA3RNC.com.

I was first drawn to the TR-35 after reading the opening paragraph of the product description:

“Compact but powerful 4-band, 5-watt CW transceiver kit that uses no tiny push buttons, and without those seemingly endless and hard-to-remember back menus. There is a knob or a switch for every function!”

Sold!

I considered buying and building the TR-35 kit, but I wanted my eventual review––this one!––to focus on the radio’s functionality and performance. So a factory-assembled and tested unit was right for this purpose, just so that any performance issues wouldn’t be a result of any shortcomings in my kit building skills.

I decided to reach out to WA3RNC and ask for a loaner. John very kindly sent a factory built TR-35 to me along with return postage and a very flexible loan period (thank you, John!). Continue reading A comprehensive review of the Penntek TR-35 four band QRP transceiver

John’s trip and POTA field reports from Nova Scotia

Many thanks to John (VE3IPS) who shares the following guest post:


Nova Scotia POTA After-Action Report

by John VE3IPS

We had planned a vacation trip out to Nova Scotia to get our lobster fix. As I always do, I prep my radio with local repeaters, look up local radio clubs, museums and check the POTA and SOTA map for locations to operate from.

I noticed that several park locations had not been activated. Thus I had an opportunity to be first activator and to get some much needed Nova Scotia parks in the Hunters logs. I printed the map and noted the park identifiers. I decided to just activate the parks that were never activated. I could have worked more parks but you have sights to see and can’t be behind the mic all the time. My antenna was prepped to be rapidly deployed in a few minutes and torn down accordingly.

I also was able to attend the Halifax ARC Hamfest on June 4, 2022.

So a vacation with ham radio elements to keep me excited with some objectives in mind.

We did visit Peggy’s Cove, Burnt Coat Head to watch the tides in the Bay of Fundy, local wineries, Lunenburg (a movie shoot was underway), the Halifax Citadel and of course eat lobster every day. I spent over $200 in gas as we did a lot of driving around (gas is just over $8 a gallon CAD), retail tax at 15% and prices for food and restaurants up by 30%. Nova Scotia is a bit more expensive than other cities.

I decided to bring my Icom 705 with a LifePO4 battery to offer 10 watts instead of the FT-891 or FT-818. Why? Because it offered a voice memory for calling CQ Parks, built in SWR meter and better IF filters over the FT-818. I wanted to cover the Marine and VHF/UHF repeaters as well and that ruled out the FT-891.

Due to the Kleenex box form factor I ended up using a Lowe Pro Omni Trekker camera bag to use as a carry on. This included a Nikon V1 camera and Binoculars.

Solar POTA: Pairing the Buddipole PowerMini 2 with folding panels and the FT-817ND at New River State Park

Photo by K4TLI

I’m often asked if I ever charge my LiFePo4 batteries in the field via solar energy.

Truth is, I’m a big fan of solar, but I’m rarely in the field long enough to need to recharge my batteries via solar when performing SOTA and POTA field activations. It’s easier to charge them at home in advance (often via the solar system at our QTH).

In fact, one of my 3 Ah LiFePo4 Bioenno batteries can easily take me though 3-5 activations or possibly more, depending on the length of the activation and the rig I’m using.

For longer forays into the field, however, I love going solar.

Indeed, every few years, my family will stay in an off-grid cabin on Prince Edward Island (Canada) for up to 6 weeks at a time. Solar is the only practical way to stay on the air that length of time.

Of course, I also like having a solar option, when doing proper primitive/off-grid tent camping.

In the past, I’ve used a very simple portable solar charging system based on a variety of rigid and folding panels, a Micro M+ charge controller, and sealed lead acid batteries. The batteries are of course heavy, but they work brilliantly for fixed operations.

These days, I’m fully invested in LiFePo4 batteries and my Micro M+ charge controller is not really designed to pair with the BMS (battery management system) in my Bioenno packs.

Bioenno sells a number of affordable solar charge controllers, but most resemble units that are used in permanent installations.  I wanted something more portable and, ideally, something with Anderson PowerPole connections.

Late last year, I discovered the Buddipole PowerMini 2:

I contacted Buddipole with a few questions about the unit and to find out when they would be in stock again (at the time, they were on back-order and indeed they are at time posting this report).

Turns out, they were to be restocked the next day, so as soon as inventory was showing on the site, I ordered one. Continue reading Solar POTA: Pairing the Buddipole PowerMini 2 with folding panels and the FT-817ND at New River State Park

SOTA featured on BBC Countryfile

A number of readers and friends here and in the SOTA community are simply chuffed that Countryfile on the BBC recently featured a short segment about Flat Holm, its historical ties with Marconi, and modern portable amateur radio.

I tried my best to view this yesterday from the US, but shows like this on BBC One are geo-blocked via the BBC iPlayer…which is, evidently, clever enough to recognize VPNs.

However, I notice the segment has recently been posted on YouTube, so if like me you’re outside of the UK, I encourage you to watch it quickly before it gets pulled.

Enjoy!

Click here to view on YouTube.

The segment features our friend Fraser, MM0EFI (remember his brilliant field report chock-full of Land Rover nostalgia–?) and a number of other amateur radio operators.

Fraser posted his own video showing the other side of his contact with the Countryfile crew:

Fraser sat on top of that gusty summit for quite some time before the BBC crew were ready, but it looks like he had a lot of fun.

You did a brilliant job, Fraser! So glad the propagation worked in your favor.

What’s more, I love the fact that Countryfile crew looked at SOTA with both curiosity and excitement.

Bravo to all of the radio ops featured in this segment; you’re all proper ham radio ambassadors!

Scott builds a compact random wire antenna with 9:1 Unun

Many thanks to Scott (KK4Z) who writes:

Hello Thomas,

I just finished an antenna project using an antenna I got from you. I call it my K4SWL antenna. I added an UnUn to it:

K4SWL Antenna Plus

Recently, I have had the desire to try my hand at winding toroids. They have always been a mystery to me. Today’s project is winding a toroid for 40-10 meters. My target antenna is one I learned from Thomas, K4SWL. It is a random wire antenna that is 29.5 long with a 17 foot counterpoise. It is a great antenna and works well at park campsites. I either string it up in a tree or I use my 20′ B&M fishing pole.

[Continue reading on KK4Z’s website…]

Scott KK4Z

Thank you for sharing this, Scott. I’ll be the first to admit that I can hardly take credit for the antenna design as it’s been out there for ages, but I do love this simple antenna and it has become an invaluable member of my field antenna arsenal.

I, too, have been planning to build a 9:1 UNUN and pair it with the speaker wire antenna just to make that match a little easier. 

Thanks so much for sharing this and your excellent build notes!

W7L in the 7 Lakes Wilderness Area

Many thanks to Paul (W0RW) who shares the following field report:


Exploring the 7 Lakes Wilderness Area 

It was as a dark and drizzly morning as my XYL (Sharon) and I (Paul)  went up to Cripple Creek, Colorado, and then drove down the Gold Camp Road. The colorful Aspen trees were changing color and even in the drizzle had brilliant yellow and red colors. We proceeded up Fire Road 376 to 11,000 feet, The entrance gate to 7 Lakes. The  South Slope Ranger opened the gate for us and checked our registration. I got out the rain and snow gear and got my poncho on.

(My radio is waterproof).

I don’t normally operate in the rain and snow but this area is available only by pre-registration. The day I picked happened to be a Hurricane remnant day.

The area was just opened to the public this year and there are only 20 cars authorized per day. The area has been closed to the public since 1913–before wireless! This was opening day so I  picked the Special Call Sign, ‘W7L’, to operate with because it is the tri-graph of the name of the area, Wilderness 7 Lakes.

We set out on the trail for Mason Reservoir. As we arrived at the reservoir a snow cloud descended on us accompanied by thunder snow. There were 6 people there already fishing. They said fishing was great, mostly ‘catch and release’. One of the lady fishermen saw the big 10 foot whip on my back pack and asked me if I would like her spot on the lake to fish. I told her I was working ‘catch and release’ on 20 meter CW and I didn’t have a fishing license.

The radio I was using was my 30 pound PRC319 backpack radio which runs 50 watts.

The trail head has a new restroom and a covered picnic table area with one tree nearby for picnic table operations. This is a deep valley (That’s where most reservoirs are kept). So you might need more than 5 watts to get over the hills.

If you have ever taken the COG Railway out of Manitou Springs to the top of Pikes Peak, you have probably seen this area from the “Son of a Gun” Hill.

Warnings: These are high altitude  trails; you must be in good physical condition to hike. Elevations at 7 Lakes range start at 11,000 feet; if you are arriving from a low elevation consider acclimating at 6,000 feet for one or two days.

Bring plenty of water and pace yourself.  Altitude sickness is common. Symptoms can be shortness of breath, nausea, dizziness, headache, dyslexia. Also Loss of clear thought processes like: locking your keys in your car (This happened to one of the fishermen), leaving your log on a rock, forgetting how to program your radio, forgetting your operation time schedule or what the upper band limit of the 17 meter band is.

WG0AT, Steve, was with me on my second trip and he made this cool video:

Then he took a side trip from 7 Lakes and went up the adjoining 12,000 foot, Almagre mountain.  See the history at : http://en.wikipedia.org/wiki/Seven_Lakes,_Colorado

You can reserve your place there by applying at  the Colorado Springs web site:

Wow, Paul! That sounds absolutely brilliant! And taking a PRC-319–? Wow! What a way to add a little extra challenge to your high altitude radio adventure!

Thank you for sharing this, Paul! 

The QRPer Board: A new discussion board for QRPer.com

Friends, I’d like to share some good news with you!

The short version:

I’ve created a QRPer discussion board that anyone can join, free of charge, at QRPer.net.

My hope is that this will be a spot for community members to get quick answers to questions and connect with other like-minded operators.

Everyone is welcome and this board is already populated with a number of moderators who will make sure that all questions–no matter how simple–are welcome. Trolls and rude people will be weeded out.

I would encourage you to create an account and check it out: http://qrper.net

The long version:

In the past, I’ve mentioned in posts that email from readers and subscribers (of both QRPer.com and the SWLing Post) has increased to a point that I can no longer keep up with them. It became very evident when I went camping in West Virginia last month and came back home to find no less than 60 messages in my inbox. These 60 messages were all ones needing some sort of reply or acknowledgement–they didn’t include notifications and SPAM.

I take pride in replying to each and every message I receive, but sadly I can no longer keep up with the volume. Sadly, I don’t have enough time especially with my busy family life.

In fact, I realized recently that replying to emails is actually taking a large bite out of the time I have to do content creation. I can’t let that happen, because that could quickly lead to burn-out. Both of my sites are pure labors of love and I enjoy them immensely.

Moody weather and a trailside activation with the amazing Discovery TX-500 and PackTenna EFHW

As I mentioned in a previous post, I’m starting to sort out the gear I’ll take on a long road trip this summer. I still haven’t quite decided which radio will accompany my Elecraft KX2, but the lab599 Discovery TX-500 is on my very short list.

I pulled the TX-500 yesterday to do a firmware update and found my logbook for an activation I made on February 16, 2022. For the life of me, I couldn’t remember writing the field report for that activation.

I checked my YouTube channel and, sure enough, buried at the bottom of my video list was the activation video marked as “unlisted.”

That bit of time between mid-February and mid-March was crazy for me. I was in isolation for a week (thanks Covid) and had a very hectic family schedule. I accumulated a small backlog of videos then and this one was lost simply lost in the shuffle.

Here’s the report and video from that activation:

Clear Creek Trail

It was Wednesday, February 16, 2022, and I was driving to my parents’ house to help them with a few projects. I had enough time to make a little detour to the Clear Creek Access of South Mountains State Park (K02753) and had two things in mind: a good hike and trailside activation.

The weather? Man oh man was it was fickle.

On the interstate, I got caught in a proper downpour and traffic slowed to a crawl.

I thought about throwing in the towel then, but I made a promise to myself that I would continue driving to the park if it wasn’t raining when I approached the park exit on the interstate.

You know what? The rain stopped maybe 3 miles before the exit. So I continued my drive. Continue reading Moody weather and a trailside activation with the amazing Discovery TX-500 and PackTenna EFHW

The Canadian Basic Exam

As I mentioned in a previous post, I’ll be spending a few weeks in Canada this summer and will certainly play radio.

I’ve decided to bite the bullet and study to hopefully pass my Basic license exam while there.

I say “hopefully” because my timing couldn’t be worse.

I started studying about 2 weeks ago in earnest–allowing myself one month of prep before my trip–but frankly, I’ve been so busy I’ve had almost no time to dedicate to  studying. In fact, a good 5 days of my two weeks were taken up with a POTA camping trip in WV.

Why in the world do I do this to myself?

That’s what I keep asking.  🙂

There’s no logic in getting a Canadian license because as a US license holder, I can simply add /VE2 onto my call while in Québec et voilá I’m legally on the air!

That and, here at home, I’m juggling numerous projects before we leave, so study sessions are crammed into short openings and are sporadic. Not how I like to study for something like this.

Thing is, I want to fit in the bulk of my studies within the next two weeks so that as soon as I’m on Canadian soil, I can go ahead and schedule a remote exam (one must be in Canada to take the exam even if via Zoom). I don’t want to spend my whole vacation studying, so I’d like to knock this out very early on.

So why get a Canadian license?

In the past, our family has spent whole summers in Canada primarily in Prince Edward Island and Québec. We know there’ll be many more of these trips in the future and my wife and I even entertain the idea of spending nearly half the year in Canada once we’re empty nesters.

I feel like it would be beneficial to have an actual Canadian call for those extended trips; especially in PEI where it’s so easy to grab DX almost anytime I hop on the air.

In fact, my callsign–should I pass–will have a VY2 prefix because that’s where our mailing address is.

There’s another reason, if I’m being honest with myself: I like the challenge of trying to pass the test. It’s just…my timing is kind of [understatement]  crappy. Continue reading The Canadian Basic Exam
