Elecraft KH1 Tabletop Mode: The new KHRA1 Right-Angle Adapter makes for a super-portable POTA machine!

22 Comments

It’s funny how sometimes one small accessory can have a huge impact on a field radio kit.

When I first learned about the Elecraft KH1 (basically, the day I was invited to join the volunteer testing group), I felt like Elecraft had designed my ideal QRP radio. The KH1 is super compact, weighs 13 oz completely loaded, covers my favorite bands, and has features I would expect in much pricier radios. It reminded me of my beloved KX1, but even more portable with more features.

The KH1 caters to handheld or pedestrian mobile operating–at least, that was the overarching design objective. It accomplishes this amazingly well. It’s so easy to operate handheld, and there’s nothing else quite like it on the market. I suspect that when others copy the design (I’m sure they’re already doing so–!) it won’t be as versatile, functional, and lightweight.

At the end of the day, though, I feel like I’m only using the KH1 pedestrian mobile about 30% of the time I have it on the air. Of that 30%, I’d say that only 10% of the time I’m pedestrian mobile while activating, and 20% of the time I’m doing little impromptu radio sessions in parking lots, ballparks, while visiting family, and even on my own mountain property.

While handheld operating is simply a game-changer, I knew I wouldn’t do this 100% of the time with the KH1. It’s for this reason that my very first bit of proper KH1 feedback to Elecraft, well before I had my hands on a prototype, was that a right-angle adapter for the whip antenna would truly round out the KH1’s field prowess.

This would basically give my KH1 the same functionality of my beloved KX2 and AX1 antenna combo, but in an even more portable package.

Turned out, Elecraft already had a right-angle adapter on the design board!

Fast-forward to present day…

Last week, Elecraft sent me a prototype of the right-angle adapter to test and evaluate. They’ve given it the model number KHRA1.

Full disclosure: Elecraft also gave me permission to post a video and article about this new accessory even though (at time of publishing) it’s not even showing up on their website. I will, however, link to it here as soon as Elecraft makes it available. This is an item I would otherwise have tested in private–thanks, Elecraft!

The KHRA1: Small accessory, big impact!

Illustration Source: Elecraft KHRA1 Instruction Manual

The KHRA1 is a simple adapter. Other than metal attachment hardware, most of it is lightweight and 3D-printed from a durable material (I assume the same material they use in the KH1).

Attaching it to the KH1 is very easy.

First, you unthread the large metal thumb nut from the KHRA1. You will need to hold together the remaining KHRA1 components (legs and attachment bracket) so that they don’t come apart before you attach them to the KH1. This is actually pretty easy to do, but users should know to follow the KHRA1 instruction sheet. If these parts fall apart in the field, it might require a bit of searching the ground for the pieces.

You simply thread the large thumb nut onto the KH1’s whip antenna antenna port, then thread the rest of the KHRA1 bracket/legs onto the large thumb nut.

Check out Elecraft’s illustration:

I then position the KHRA1 legs as shown above, then tighten the KHRA1 adapter so that everything is secure.

It’s super simple to do, and you can see this process in my activation video below.

Speaking of an activation…

On Saturday, March 2, 2024, (yes, only two days ago) I had my first small window of opportunity to squeeze in a POTA activation and test the KHRA1.

That day, my daughters and I had a number of errands to run, then a three-hour round-trip drive to pick up my wife. We were on a very tight schedule, but I had a 30-ish minute window of opportunity to fit in some POTA radio therapy.

I set my sights on the easiest-for-me-to-hit POTA site on the Blue Ridge Parkway: the Folk Art Center.

Amazingly, I discovered that morning, that the KHRA1 fits in my Pelican M40 Micro case along with my KH1, whip, counterpoise, key, spare N6ARA key, and earphones.

With the KHRA1, this means my M40 field kit can do both pedestrian mobile and tabletop operating. Woo hoo!

The weather that morning was simply glorious. A very wet front swept through the previous day leaving behind clear skies and warm temps. Frankly, it was a bit odd activating without wearing a jacket or hoodie.

On The Air

Setting up was quick and easy, even though this was my first time using the KHRA1 in the field.

I hopped on the air and started calling CQ. Once spotted (for some reason the RBN auto-spotting feature wasn’t working again), the contacts started flowing in.

I worked a total of 18 contacts in 16 minutes. It hardly gets better than that for a CW activation!

I had to call QRT after my 18th contact. Even though I had a 30-minute window to POTA, nearly 14 minutes of that was taken up with my intro and summary for the activation video.

I called QRT with a small pileup still in place. I really hate doing that, but I had a schedule to keep!

QSO Map

Here’s what this five-watt activation with a 4′ telescoping whip antenna looked like when plotted out on a QSO Map:

Activation Video

Here’s my 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.

A super-portable, low-impact POTA machine!

The KH1 works amazingly well as a tabletop radio when combined with the KHRA1 adapter.

At the end of the day, the KHRA1 is a very simple piece of hardware, but it effectively transforms the KH1 from a handheld radio to a tabletop.

Of course, I’ve used the KH1 numerous times with wire antennas in a tabletop configuration (I’m a massive fan of wire antennas) but the ability to use the 4′ whip antenna and internal KH1 loading coils means that I can operate anywhere I have a surface.

As I mentioned in a previous post, in some cases, low-impact, and low-profile are key to positive park relations.

Herein lies the thing I love about my KX2/AX1 pairing as well. It’s just with the KHRA1, the KH1 makes for an even smaller, lighter-weight field kit.

Any negatives? The only one I’ve come up with is that the KH1 is so lightweight that I realize I need to carry a small piece of shelf liner (something like this) to provide the KH1 with a bit more grip on a slick park table, especially those composite ones.

Again, I will update this post when Elecraft announces KHRA1 pricing and availability.

Thank you

I still can’t believe the entire kit fits in this small case. Even when I put the KHRA1 thumb screw on backwards!

Thank you for joining me on this quick little tabletop activation!

I hope you enjoyed the field report and my activation 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 week ahead and play some radio!

Activating Silver Sands State Park by pairing the QRP Labs QDX and the FT8CN Android App!

FT8CN Field Report

By: Conrad Trautmann (N2YCH)

February 24, 2024

I successfully activated Silver Sands State Park, K-1716, for Parks on the Air using the FT8CN Android app and a QRP Labs QDX transceiver.  Here’s my field report.

Thinking about ways to further shrink down my mobile kit, I wondered if WSJT-X would run on a mobile phone. After some internet searching and reading various groups.io messages, I discovered that FT8CN is a digital modes app that runs on an Android device. It is also single wire compatible with the QRP Labs QDX transceiver carrying both the CAT control and audio. My goal was to see just how light and compact I could make my digital mode kit. Here’s a look…

Lenovo Android Tablet, QRP Labs QDX transceiver and a Bioenno BLF-1203AB 12V Battery

The Android device is a Lenovo Tab M8 (4th Gen), which can be found on Amazon [affiliate link]for about $80. It has an 8” screen, which is slightly larger than my mobile phone. I was happy to have the extra screen real estate since there’s a lot going on in the app and the size made it easy to see it all.

The FT8CN software can be found at N0BOY’s github site, https://github.com/N0BOY/FT8CN/releases. The most recent revision as of this writing is version 0.92. It’s an .apk file, which to install, you need to give your Android device permission to download via the browser. This is a direct download to the device and not going through the Google Play store, so it hasn’t gone through any security checks or validations. As with any of the software we use in ham radio, caveat emptor, or buyer beware. I would carefully consider this before downloading it to your primary mobile phone.

With that said, if you Google FT8CN, you’ll find plenty of videos and online resources to guide you on how to install it and set it up, so I won’t go into those details here. It’s fairly intuitive and each configurable field has an information button you can click for in-app instructions or explanations of what each does.

The Lenovo tablet has a single USB C port used for charging and connecting external devices, so I used a USB C to USB Type A adapter to connect to the QDX cable. Since this setup only requires a single wire, I plan to use a USB C to USB Type B cable so no adapter will be needed. For the first outing, it worked just fine this way.

The QDX’s on-board audio card and the transceiver control are all integrated into the application. It supports a number of popular transceivers including the QDX. When I connected the USB cable to the tablet, it automatically launched the application and presented a screen to click with the USB port. Once selected, the app displays a message saying the connection was successful.

I brought my Bioenno BLF-1203AB 12 volt battery to power the radio, which is actually larger than the QDX. That’s another opportunity for me to downsize the kit, finding a smaller LiFePo battery. I know some QDX owners use a standard  9 volt battery, that would certainly lighten the load. My QDX is built for 12 volts but it is possible to build it configured for 9 volts and still get full power out.

As pictured above, the entire setup was the 8” tablet, a USB cable connection to the QDX, a power cable from the battery to the QDX and an antenna cable. For the test, I used my Buddipole with a 17’ whip and counterpoise, which I knew would be resonant on 20 meters. I wanted to avoid needing to use a tuner. There is a compact tuner available which is about the same size as the QDX called the ATU-10, which works well if you need one and is about the same size as the QDX. I think it would be great to pair this kit with a Packtenna EFHW 20 meter wire antenna, which is also resonant and tiny enough to pack in a small bag with the rest of the kit.

Equipment List

Extra Items I brought for the test

I did a quick test of my antenna using the RigExpert antenna analyzer and at 14.074 MHz, I had 1.5:1 SWR, so I didn’t need to worry about damaging the final power amplifier on the QDX.

A windy day bending my vertical to one side at K-1716, Silver Sands State Park, Connecticut
AntScope shows a decent match at FT8 frequency.

Once everything was connected, I immediately started receiving stations. Here’s a screen shot of the decodes screen (below). The waterfall is on the left and decode list is on the right.  Odd and even cycles are easy to see with light and dark shading behind them. They are also labeled “0” and “1”.

I think one of the coolest features of this application is the labeling of the stations in the waterfall.

Here’s the same screenshot rotated to see the waterfall more easily.

You can see that the text of the stations calling CQ are a different color than the others. You can also see KS4YT calling CQ POTA. I always try to call other POTA activators when I see them to get the park to park QSO. When a station is calling you, the text is pink.

POTA is changing park prefixes and, in some cases, park numbers

16 Comments

I’ve just learned that the Parks On The Air (POTA) admin is in the process of cleaning up and reorganizing the way Programs, Locations, DX Entities, and Parks are stored in its database.

Many thanks to Alan (W2AEW) who shared a link to this document which explains what they’re doing and even links to logs as they implement these changes.

In short, this will have an effect on activators, especially, because there’s a decent chance you will be using a new park prefix, and in some cases, possibly new park numbers.

A number of POTA prefixes have changed already.

In fact, if you’re activating in Canada, you might have already noticed that the park prefix is no longer VE, but is now CA.

As an example, in my activator logbook, what was once VE-1596 (Hog’s Back Conservation Reserve) is now CA-1596.

Here in the States, the prefix will soon change from K to US.

These prefix changes will happen for many other countries as well.

Of course there’s nothing, as an activator or hunter, you need to do other than start using the new prefix when it has been implemented. All of your old logs will automatically update in the POTA system with the new prefixes and/or numbers.

It might take time for logging applications like HAMRS to adjust to new prefixes. Activators might need to use the old prefix while live-logging during an activation, then use a find/replace string in a text editor later to fix the ADIF file.

Again, check out this document on the POTA website which goes into much more detail.

Thanks again, Alan, for the tip!

The POTA Babe Goes Fishing (Sort of)

18 Comments

Parks on the Air offers a diversity of properties. In addition to those that commonly come to mind like state parks, forests, and national wildlife refuges, there are wildlife management areas (WMA) about which I’ve written and fishing lakes. This past week the POTA Babe visited Evans County Fishing Lake (K-7464) here in Georgia.

Source: Google Maps

The drive to the property was pleasant and relatively quick. On the way, I drove through the town of Pembroke. According to Wikipedia, this small community was a railroad town and turpentine shipping center and named after an early resident, Pembroke Whitfield Williams.

I took to heart Thomas’ advice in his recent post “Building Positive Park Relations” and contacted the office managing the property before my visit. I spoke with an employee who confirmed they had no problem with me putting a temporary antenna in a tree at any of the properties that district office manages. I also made a point to introduce myself to the DNR employee on site when I arrived. As soon as I said the words “ham radio operator”, he responded that they love having ham radio folks on the property! (Kudos to all those who have activated there before and were good ambassadors for our hobby.)

As I did for the Hiltonia WMA activation, I checked the satellite view of the property on Google Maps beforehand. There are three lakes with Bidd Sands Lake being the largest. (Bidd Sands is named after a beloved member of the local community who gave his life in Vietnam  in support of the men he was leading.) At the east end of the lake is a dyke. That seemed a great place to set up, partially because of the openness but also I was likely to not be in anyone’s way.

It was still rather chilly despite the sunny sky overhead so I chose to operate from the car rather than set up my Helinox chair and be out in the open. At the end of the dyke was a large oak tree just begging for the Tufteln EFRW antenna. I had the new Chelegance MC-750 with me but I’ve grown partial to putting antennas in trees. I love the flexibility of effortlessly changing from one band to the other without adjusting a whip and/or counterpoise as you have to do with a vertical.

Teri: A Request from the POTA Babe to QRPer Readers

16 Comments

For those regular readers of QRPer.com, you know that this POTA Babe has a goal of 60 new-to-me park activations for 2024. I am planning a POTA trip this summer to North Carolina and/or Virginia. I will be on the road for eleven to twelve days with nine to ten of those days potentially available for activations. I’d like to hear from y’all what one park you think I should visit and why.

You can either leave your suggested park in the comments below or email me via the address on my QRZ page. As summer will be here before we know it, I’d like to nail down my plans soon. Please share your suggestions by Wednesday, March 6th.

For safety reasons, I will not share my itinerary before the trip; however, I will give credit in the articles I write from the trip to the op (or ops if the park is suggested by more than one person) who suggested that park.

Thank you in advance for your assistance! Keep having fun with your QRP adventures!

QRP & Coffee: Late-Shift POTA using the new Chelegance MC-750 80 Meter Coil!

1 Comment

I mentioned in a previous post that Jesse at Chelegance had sent me some antenna goodies to evaluate. One of them was the MC-599 portable dipole antenna which you might have read about in my previous field report.

Another item he sent, which I was equally excited about, was an 80-meter coil for my beloved MC-750 vertical antenna.

In the spirit of full transparency: he sent this at no cost to me, and, as a reminder, Chelegance is also an affiliate of QRPer.com.

I’ve been eager to take the 80-meter coil on a POTA activation because 1.) if it proved effective, it would be great to have such a low-impact, low-profile antenna for 80 meters, but 2.) it’s been very difficult to fit in an evening POTA activation with my family life.

It would have been difficult to gauge how effective an 80M antenna performs in the late morning or early afternoon when I typically activate local parks/summits.

On Wednesday, February 6, 2024, a two-hour window of opportunity opened. One of my daughters had a dress rehearsal that night, and I knew of a nice, quiet, secluded POTA spot only 25 minutes away.

Pisgah National Forest (K-4510) and Game Land (K-6937)

My original plan was to arrive at the Looking Glass Falls’ picnic area, deploy the antenna, fire up the stove, make some coffee, eat on-site, then begin my activation after the start of the UTC day.

So why wait for the new UTC day?

Mainly because once you hit the new UTC day, it counts as a new activation. That really works in your favor as an activator if your goal is to complete a valid activation (with ten contacts) and you’ve enough time to do that before the UTC rollover. If you time it all correctly, you could activate double the parks with a minimum of 20 contacts (split 10/10). In my case, that would mean a total of four parks activated in one evening (since this was a two-fer).

I decided fitting in an activation prior to the UTC rollover simply wasn’t worth the rush.

Once I arrived on-site, however, I was already changing my mind.

I started my activation video, deployed the MC-750, and looked at my watch. I had roughly 15 minutes before the UTC rollover.

It would be tight, but I decided to give it a go and try logging ten contacts before 18:59:59 local (or 23:59:59 UTC).

If I couldn’t log ten before the UTC day, who cares!? It would be a fun challenge for sure, but I wasn’t going to cry if I couldn’t gather enough contacts for a valid activation.

There was another factor, too: operating 80 meters with a 17′ loaded vertical isn’t exactly “efficient.” My theory, though? It doesn’t need to be efficient. It’s crazy portable, convenient, and as a POTA activator, I only need enough performance to get the job done.

Time to hit the air!

On The Air

I’d scheduled my activation on the POTA website, so was relying on it to spot me via the Reverse Beacon Network.

I started calling CQ POTA and the contacts started rolling in… very… slowly.

Well, it felt slow because I had a goal of ten contacts in fifteen minutes. Continue reading QRP & Coffee: Late-Shift POTA using the new Chelegance MC-750 80 Meter Coil! →

QRP POTA and testing the new JNCRadio MC-599 portable dipole antenna!

7 Comments

In late December 2023, I received a package from Jesse at JNCRadio/Chelegance. It was their new MC-599 portable dipole antenna. They sent it—full disclaimer: at no cost to me—for evaluation, but shortly after receiving it, life got crazy and I was delayed in taking it to the field.

Fast-forward to February, and I was eager to take it to the field and see how it might perform. On February 5, 2024, a nice window of opportunity opened in the afternoon while one of my daughters was rehearsing A Midsummer Night’s Dream with her cast. Pisgah National Forest and Game Land were a 20-minute drive from her meeting site, so I headed there to deploy this new antenna.

The JNCRADIO MC-599

On-site, I pulled out the two main components of the MC-599 dipole system: the bespoke padded bag holding the antenna and the portable mast.

I knew the basics about assembling the MC-599 because I had watched a video on the Chelegance website that morning.

However, this was the very first time I had deployed the MC-599. I had never even removed any of the antenna components from the padded bag.

With this antenna, it’s best to have an open area for the two sides of the dipole (two telescoping whips) to fully extend without touching tree branches, etc. I had one particular picnic site in mind at the roadside picnic area I chose, but a couple was having a picnic there when I arrived. I waited to see if they might be leaving soon, but they weren’t, so I chose a site I had used before, even though it was flanked by trees.

Assembly was easy: I simply attached the center of the dipole to the 13′ mast, then attached the two telescoping whips to either side and extended them to the 20M position silkscreened on the whip (identical to the MC-750 vertical markings—see below).

Next, you simply attach your coax to the center of the dipole, then extend the mast all the way up.

I had to avoid touching tree branches, but it actually fit quite easily into this small space.

Since it was a bit breezy, I used some line to guy the mast. Ideally, you’d want a minimum of three guying points, but I only had two lines with me, so I made do, and it worked fine—the antenna was stable.

Next, I set up my radio: the Yaesu FT-818ND. Since the MC-599 was, in theory, resonant, I didn’t need an ATU for a match.

I turned on the FT-818 and discovered that the SWR was a perfect 1:1. Amazing.

I suppose I shouldn’t have been surprised because my Chelegance MC-750 is always perfectly resonant (without needing a transformer) simply following the whip markings for guidance.

I should note here that the MC-599 can handle up to 200 Watts PEP—I was pushing 5-6 Watts. Also, the frequency range using the whips is from 20-6 meters. Chelegance also includes two 7 MHz wire elements that can be deployed in an inverted vee shape to play radio on the 40-meter band. It’s an efficient system and has many fewer components than a Buddipole systems I’ve used in the past.

On The Air

Keep in mind that my POTA site was in a deep valley, flanked by high ridge lines–I wasn’t sure what to expect as I hopped on the air.

I started calling CQ POTA and the first station I heard was DL1OK operating in Spain as EA8/DL1OK. Logging Dmitrij was a good sign indeed for this portable dipole!

Stations kept flowing in. I worked my first ten contacts in ten minutes.

I continued working stations in a continuous pileup until I ran out of time. I ended up logging a total of 46 contact all within 50 minutes. I did spend a few extra minutes (as I always do) trying to pull out weak stations and slower code stations.

What fun!

Here’s what this five-watt activation looked like when plotted out on a QSO Map.

Note that this map does not include my contact with EA8/DL1OK in Spain:

Here’s my 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.

MC-599 notes

I’ve got to admit: the MC-599 made a great first impression.

As with the MC-750, I’m most impressed with the build quality. The components are all sturdy and nicely machined. The padded case was custom made to hold the MC-599 and its components. Everything fits together as it should and—again—was resonant when deployed according to the whip markings.

Even on this inaugural deployment, it didn’t take long to set up. The next time I deploy it, it will go even faster. Packing it up afterward (as you can see in the video) went very quickly.

Keep in mind: the MC-599 is a low-impact, high-profile antenna.

If you’re at a site that doesn’t allow antennas in trees, the MC-599 could be an excellent option. Other than using optional guy lines that would require tent stakes in the ground, it would have no impact on park grounds.

I love the fact that the MC-599 is self-supporting. This would be an absolutely brilliant antenna to use at parks with wide-open spaces and few trees for support.

That said, it is not a stealthy antenna. In fact, portable dipole antennas are some of the most conspicuous portable antennas you could deploy. They’re maybe slightly less conspicuous than a hex beam or Yagi. Even though I was cloaked by a few trees, the couple that was occupying the picnic site I had hoped to use couldn’t help but stop by on their way out and ask what it was I was doing. I bet if I had been using a wire antenna, they wouldn’t have even seen it.

I would always ask permission before setting up an antenna like the MC-599 at, say, a small historic site or urban park.

I could also see using the MC-599 for SOTA (Summits On The Air), but primarily on summits that are either drive-up, or where the hike is minimal. The aluminum alloy mast is lightweight for its size, but it’s quite large to consider taking on an extended hike. However, for a nice drive-up summit, I imagine you could work some serious DX. Just bring a few guy lines in case it’s windy.

I do think the MC-599 would make for a great Field Day antenna. Since it can handle up to 200W PEP and is easy to lower and switch bands, it would be a brilliant portable option for those operating a multi-band 100W rig.

But obviously? It’s an exceptional performer with QRP power. It’s hard to beat a dipole even when it’s only 13′ off the ground.

Thank you

Thank you for joining me on this fun activation!

I hope you enjoyed the field report and my activation video as much as I enjoyed creating them!

Chasing Bands: Two Truck Activations take Brian closer to the James F. LaPorta N1CC Award

Parked in the lot at PA State Game Land 074

Two Truck Activations:  Racking up Bands and DX

by Brian (K3ES)

One of the things I like best about living in Western Pennsylvania is that after a stretch of heavy winter weather, we always seem to get a bit of a break.  The break never lasts long, but the sun comes out and the temperature warms enough to hold a promise of spring.  The first week of February 2024 gave us one of those respites.  With rising temperatures, the snow melted, a strange yellow disc appeared in the sky, and this operator’s thoughts turned once again toward POTA activations, and a free Sunday afternoon provided a perfect opportunity.

A Long-Term Goal

For just over a year, I have been working slowly toward POTA’s James F. LaPorta N1CC Award for activators.  I am under no illusions.  This goal may take me another year to complete on my terms.

The award requires an activator to complete QSOs on ten different amateur bands from each of ten different Parks on the Air entities.  To the extent possible, I am working to finish all of the needed contacts using CW mode and QRP power levels.  So, one specific part of my afternoon outing would include an attempt to make a QRP CW contact on my tenth band from PA State Game Land 283, K-8977.  Two previous activations of K-8977 had given me contacts on each of the nine HF bands from 80m to 10m.  So this afternoon, I would attempt to make a contact on top band, 160m.

Molly supervises many of my activations, and even when the weather warms into the 40s, she prefers to activate from the truck.

The Activation Plan

With a little bit of advanced planning, POTA Dog Molly and I packed the truck on a Sunday afternoon and headed out to attempt two activations.  First, we would set up at K-8773, Pennsylvania State Game Land 074, a new park for me, where we would have about 2 hours on the air before the time would be right to move to the next park and attempt an activation including 160m.  It would be just a short drive to K-8977, and we hoped to arrive there and set up around 2100Z (4pm EST).  The goal at K-8977 was to get enough contacts for a successful activation, then shortly before sunset move to 160m and get at least one contact to complete activation of the the tenth band.

Parking areas at Pennsylvania State Game Lands are mostly unpaved, but they are well marked.

Activating K-8773

With temperatures running in the low 40s Fahrenheit, I decided Molly would be most comfortable operating from the truck.  She appeared to be quite pleased with that decision.  So we pulled into one of the parking lots at K-8773 and parked along the tree line.  I tossed my arborist line over a branch near the truck, and used it to pull up my Tufteln 9:1 35 ft random wire antenna into a near-vertical configuration.  After connecting the 17 ft counterpoise wire and laying it out along the ground, I attached the 15 ft RG316 feedline and routed it into the truck through the driver’s side door seal.

I clipped the feedpoint of my Tufteln random wire antenna to the 2m antenna on the front fender of the truck.
I threw my arborist line over a tree branch, and used it to pull up the far-end of the antenna.  A few wraps around the handle for the back window of the cap kept it secure for the activation.
The RG316 feedline runs through the door seal into the truck.

Once inside the truck, I set up my KX2, prepared my log book, and made the decision to work my way downward through the amateur bands.  Conditions proved to be amazingly good that Sunday afternoon, and my 5 watt signal yielded 54 CW contacts, including 13 DX contacts spread across 7 European countries.

Moreover, I made at least one of these contacts on each of 8 amateur bands, from 10m to 60m.  Unexpectedly, getting contacts on 8 bands during a spectacular afternoon at K-8773 also puts that park well within striking distance for completing 10 bands, just not on this particular afternoon.

Not a bad afternoon’s work at the first park, not at all!

The KX2 sits on the console of the truck, with its feet straddling one of the cup holders.  This leaves plenty of room for my log book (yes, I’m one of those dinosaurs who uses pencil and paper for logging).
Another view of the operating station.  Note the home made VK3IL pressure paddles above the log book.
Supervising this activation was a particularly difficult task.  Molly has decided that a rest is needed.  She has tucked her nose in the blanket, a definite signal that serious napping is underway.
At K-8773, I logged 56 contacts across 8 bands.  I was delighted that 13 of those contacts were DX from Europe.

Activating K-8977

Packing my gear at K-8977 went quickly.  As a most excellent POTA companion, I rewarded Molly with a short walk along a Game Land road, then a 15 minute drive on some rugged back roads brought us to K-8773.  I had operated from one particular parking lot during previous activations, but a quick look around for places to set up my antenna caused me to head for a  different parking lot.  I would be using a wire antenna that was much longer than normal, and a nearby power line was too close for comfort.

ALWAYS watch for and avoid power lines when deploying your antennas in the field!

To activate on the 160m band, I intended to use my VK160 antenna.  The VK160 is a homebrew 9:1 random wire antenna with a 144 ft radiator and three – 17 ft counterpoise wires.  At the new location it went up quickly in an inverted V configuration.  With counterpoise wires spread out on the ground, and my 15ft RG316 feedline connected and run through the door seal of the truck, it was time to get the station assembled and on the air.  This time the rig would be a KX3 with built-in wide-range tuner.  The KX3’s spectacular tuner matches the VK160 on all bands from 10m to 160m.

I was easily on the air at 2100Z (4 pm EST), and had about 90 minutes before sunset.  My plan was to begin on 40m, and collect enough contacts to assure the activation before moving to 160m around 2200Z (5 pm EST), about 30 minutes before sunset.

Activating on 40m was a safe bet, even running 5 watts CW.  Once spotted, I was working a steady pileup for about 40 minutes.  When 40m callers tailed off, I switched over to 30m for 20 minutes and picked up a bunch more contacts on the new band.  Then, at 5 pm local, I switched over to 160m.  It did not take long to start making contacts.  It was not a pile up, but the three 160m contacts were very satisfying:  eastern Pennsylvania, western Pennsylvania, and Virginia.

I called QRT at 2215Z (5:15 pm EST), packed up my gear in the remaining daylight, and drove home.  I was home in time for dinner, and Molly didn’t say a word about being late for her normal 5 pm dinner time.

At K-8977, I logged 54 contacts.  Since I worked them on 30m, 40m, and 160m, it was entirely expected that most would be located in the eastern US and Canada.  Logging 3 contacts on 160m made it a perfect outing.

I do owe an apology to QRPer.com readers, because in the pace of the second activation, I failed to take pictures during my operation.  If you are interested in visuals, please take a look at previous QRPer articles on building the VK160 and testing it during Winter Field Day 2023.

“Three Watts and a Wire: Seizing a Last-Minute POTA Opportunity with the Elecraft KX1!

9 Comments

I woke up a little too early on the morning of Saturday, February 3, 2024.

The previous evening, we recorded a Ham Radio Workbench podcast episode with my dear friend Ara (N6ARA) as a guest. It was a load of fun, and we ran over time (no surprise there). Since we started recording at 18:00 Pacific Time, it means that it was 21:00 here in the Eastern time zone. By the time the episode ended, it was well after midnight my time.

For some reason, my body clock only allowed me to sleep for five hours, but I planned to sneak in a nap at some point during the day. Our plans were modest that Saturday (only to visit my father-in-law in the hospital), and I had no intention to fit in a POTA activation.

Around noon, my daughters asked if I’d drive them to watch one of their friends in a Shakespeare performance at 2:00 PM. We quickly sorted out plans, and I grabbed my GoRuck GR1 pack, which (due to a crazy January) had hardly been touched since my activation with Hazel nearly a month prior.

Pisgah National Forest (K-4510) and Game Land (K-6937)

As you’ll hear me mention in a number of my field reports, the venue where my daughters rehearse Shakespeare and perform is a short drive to Pisgah National Forest/Game Lands. In the past couple of months, I’ve enjoyed numerous activations in Pisgah.

The weather was perfect for playing radio outdoors. It was chilly, yes, but not so cold that I needed to wear gloves.

I was looking forward to putting the Elecraft KX1 on the air again. As I state near the end of my video below, it’s one of my all-time favorite QRP rigs.

My trusty GoRuck GR1

I decided to pair the KX1 with my KM4CFT end-fed half-wave that I built for 30 meters, with a linked 40-meter extension.

On this particular afternoon, I wanted to focus on 30 meters, so as I deployed the antenna, I unhooked the 40M link.

On The Air

I started calling CQ POTA, and it didn’t take long for the RBN to spot me, and Evan (K2EJT) was the first to call (thanks, OM!). Continue reading “Three Watts and a Wire: Seizing a Last-Minute POTA Opportunity with the Elecraft KX1! →

SOTA and POTA in Japan: Ara combines travel and radio with a little help from friends

Abroad in Japan: SOTA and POTA

by Ara (N6ARA)

Getting the License

Several months ago, my wife and I were planning our first trip to Japan, and I couldn’t help but look at all the nearby SOTA summits and POTA parks and entertain the idea of activating one of them. While stunned by the sheer number of high point summits and local parks (many of which are easily accessible via Japan’s incredible public transport system), I realized one question I hadn’t asked myself yet: Can I even operate in Japan?

I recalled the concept of a reciprocal licenses from the ham test, but never really looked into it. A quick Google search yielded the JARL (the ARRL equivalent in Japan) foreign amateur radio license website, which details the process for submitting your documents to obtain the license.

However, I quickly learned that the application must be submitted at least 60 days prior to the date of operation. Problem was… I was 58 days out.

Around this time, I let my friends, Waka-san (JG0AWE), Kazuhiro (7N1FRE), and Ted (JL1SDA), know that I would be visiting Japan. They leaped into action and helped me figure out if there would be a way to obtain my reciprocal license in time, and advised me on which summits and parks would be doable with my constraints.

Thankfully, Waka-san was very generous and offered to make an appointment with Japanese government to apply for the reciprocal license on my behalf. I was absolutely stunned by this. I struggle to make appointments at the DMV office for myself, let alone for someone else!

Two weeks later, I was surprised to learn that my license had arrived. I was now JJ0XMS in Japan. This news fittingly arrived around Christmas, making it easy to remember the “XMS” part of my call. The reciprocal license I received was classified as “1AM”, meaning 1st Amateur license for mobile. This meant I could operate on all bands at power levels below 50W, which is perfect since I tend to operate QRP most of the time anyway.

It helps to have friends around the world, but please learn from my mistake, submit your JARL-96-04 application at least 60 days (plus margin) prior to your trip and obtain your license the right way. If you have any questions about the form or the process, contact Mr. Ken Yamamoto (JA1CJP) via email at [email protected] 

Band Plan

With my license sorted, the next step was to familiarize myself with the Japanese Band Plan. After careful review, I learned it is entirely possible to accidentally transmit out of band or mode if you are not careful. For example, in the US the 2m band ends at 148 MHz, but in Japan the band ends at 146 MHz. So in theory, an operator with a US radio could accidentally transmit on a forbidden frequency.

It’s also important to note that the calling frequencies are different for all bands and that some bands have dedicated emergency communications frequencies. Thankfully, the translated Japanese Band Plan covers these extensively.

Planning the Activations

I started planning my activations by setting the goal of activating at least one SOTA summit and POTA park. I figured I’d gain the experience of doing both to see how they differ from what I’m used to in the US (and writing this blog post).

For this trip, we mainly stayed with our friend in Tokyo, so I was limited to the summits and parks near the city. To start, I figured I’d take a look at the POTA map since Tokyo is a flat city (read as, no SOTA summits to be found within the city itself), so worst case, I’d only do a POTA activation.

Much to my delight, I learned that Tokyo has 146 POTA parks within the city alone… and best of all… they are accessible via Tokyo’s public transportation system! Overwhelmed with all the options, I figured the best thing to do next is to try and see which nearby parks had the most space and activation count. I figured that would improve my odds of activating without any issues.

To be honest, my main concern was putting up an antenna in a park which I’m not allowed to in, or folks approaching me to ask what I’m doing, only to run into a language barrier issue. After looking through several options, I landed on Yoyogi Park JA-1255. The park was near where I was staying, fairly large, and had almost 100 activations. 

Next was planning the SOTA activation. Since there are no SOTA summits in the city proper, it meant I would have to travel a little to get to one.

Coming from Los Angeles, one of the most car-centric cities in the world, I did not expect to find that most Tokyo residents (including my friend) don’t own a car. Renting one is an option, but I figured it’s not worth the effort. Especially since Japan drives on the left hand side of the road – which I’m not used to. That meant driving to a trailhead was out of the question for this trip. Thankfully, that wasn’t as much of a problem as I initially thought.

Looking through the SOTA map, I found several trailheads to the east of the city that are easily accessible via train/bus and short walk. Again, I looked at the activation count to get a sense of what is attainable and found Mt. Arashiyama JA/KN-032. The summit had 84 activations with a relatively easy 762ft gain across 2.25mi and the trailhead is a 15 minute walk away from the train station. The only downside was that the train ride itself was about an hour and a half away from Tokyo. But as those who do SOTA know, the commute to the trailhead is part of the journey. (I think there’s something wrong with us.)

Packing

With a game plan settled, it was time to configure the kit. One important thing to note here is that when I submitted my paperwork to apply for the license, I forgot to include the radio make/model I planned to use (required for the application process). Thankfully, Waka-san registered the ICOM IC-705, an HF/UHF/VHF all mode transceiver (which I so happen to have). This afforded me the flexibility to work a wide range of bands and maximized my odds of having a successful activation.

With the radio figured out, I thought to pair it with a portable antenna that strikes a good balance between volume/mass and performance. My hope was to cover 10/15/20m for DX and 40m for working locals, so naturally I gravitated towards my trusted K6ARK End Fed Half Wave EFHW with an added load coil, making it resonant on 10/15/20/40m. I like to use this antenna in an inverted-V configuration using a 7.2m fishing pole. Since I had one shot at each activation, I figured it would be wise to pack a back up antenna just in case something broke mid-transport, so I also decided to pack my Elecraft AX1 vertical whip antenna and T1 tuner.

For CW paddles, I couldn’t resist packing my recently acquired Ashi Paddle 45 from Mr. Haraguchi 7L4WVU in Japan. Only seemed fitting! Finally, I thought to print out copies of my US and Japanese ham radio license, and a translated note describing ham radio, SOTA, and POTA just in case someone asked what I was doing.

Welcome to Japan

As soon as we landed in Japan and settle in at our friend’s apartment, we couldn’t help but go out for a nice bowl of warm ramen at Ichiran. It was a cold night, I was jet lagged, and this was exactly the “reset button” my body needed to adjust to the new timezone. I slept like a log that night. Highly recommend. 

Since this was my first time in the country, I tried my best to absorb as much of the food and culture as possible. From the Yakitori, to the Tonkatsu, to all the various Japanese curries, and Onigiri, I was glad to be walking around the city to burn off all the calories I was consuming. Everything we ate tasted incredible!

One of the first orders of business was to visit Akihabara, the electronic town I had heard so much about. Walking through shops, I found every possible component imaginable. Want a transformer? There’s a small shop that has every variant you can think of. LEDs? There’s a shop with a selection that will make you see floating dots when you close your eyes. It was like living in a Digi-Key or Mouser warehouse.

Walking through streets and multi-story markets, I was constantly running into small radio shops. Some selling commercial radios, many selling various ham radios and ham radio accessories. One golden nugget I found was a shop that sells home-brew radios, one of which was a 47.1GHz Transverter! Where else are you going to find something like that for sale in a shop?!

One last stop in Akihabara was Rocket Ham Radio, one of the largest ham radio shops in Japan (think HRO in the US). I couldn’t help myself from buying a 2m/70cm whip antenna for my IC-705 for portable VHF and UHF operations while in town. Would feel wrong leaving without buying *something*!

POTA Activation and Logging

POTA activation day was finally here, and much to my delight, Mr. Haraguchi (7L4WVU) reached out to say he was available to meet me at Yoyogi Park for a joint activation. Continue reading SOTA and POTA in Japan: Ara combines travel and radio with a little help from friends →
