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!

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!

QSO Map

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:

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.

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!

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!

Field Radio Kit Gallery: K4ZSR’s Xiegu X6100 Field Kit

Many thanks to Zach (K4ZSR) who shares the following article about his portable field radio kit which will be featured on our Field Kit Gallery page. If you would like to share your field kit with the QRPer community, read this post. 

K4ZSR’s Xiegu X6100 Field Kit

by Zach (K4ZSR)

My primary portable radio station is based around the Xiegu X6100. This was the first HF transceiver I bought after getting my ticket, and I have taken it on well over 100 POTA and SOTA activations across ten countries. Over time, I have learned what does and does not work for me and my operating style, and my field kit now has exactly what I need.

I have used several different packs to hold my portable radio gear, but my current favorite is this Quechua NH Escape 500 from Decathlon (I bought mine in Romania, but you can order them online). While designed as a laptop bag, this pack has all the features I need to carry for radio gear: full-opening main compartment, padded laptop/tablet sleeve, waist belt, good internal organization, and extra room. My field kit always stays in this bag, unless I am going on a long hike or camping.

The heart of this field kit is a fully self-contained station in a semi-hard side case (meant for a portable projector). As long you have a tree or other antenna support, everything you need is in this case. I always have more equipment with me, but this is the bare minimum. Two modifications I made to make the kit smaller was replacing the stock mic coil cable with an ultra-slim CAT 6 cable, and making a 6-inch power cable.

Adding my Microsoft Surface Go 2 tablet for logging and running WSTJ modes, and my field kit comes in at just over 9 lbs (ignore the scale, the tablet case was empty in this picture).

If I am going to be operating in an accessible and open area, I may bring my vertical whip antenna system. This is one of my newest additions, I assembled this antenna over Christmas 2023. I wanted a ground mount system for a 17 ft whip antenna, but I needed it to pack down relatively flat to be able to carry easily in a back pack. My solution was a modular base designed like a pedestal mount used for soccer flags. Even in somewhat soft ground, this base is incredibly stable despite the small size of the ground spike.

Gear

  1. Wolf River Coils 17’ SS whip
  2. 25ft RG-8X coax
  3. Tent Stakes
  4. Wolf River Coils Sporty 40 coil
  5. Faraday cloth
  6. K4ZSR ground spike vertical antenna mount

Assembled, the mount is inserted into the ground until the disk makes firm contact. The spike and the 3/8-24 mount are removable for packing, and the aluminum boss has 4mm holes for inserting banana plugs to ground the faraday cloth, or to attach ground radials.

Here is the antenna system assembled and in use at K-2949, Harpeth River State Park.

My true passion for amateur radio is portable operations, and as I add to my collection my field kits will grow and evolve. The most important lesson I have learned operating portable is to have simple, durable kit that you are very familiar with. That way when the situation is different than expected, or conditions change, you are prepared to adapt and overcome.

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.

Many thanks to Steve (VA3FLF) who shares the photo above and notes:

Even kittens read QRPer!!

Her name is Jolene, Jojo for short. We have had her about 3 weeks and she is a Devon Rex. She is a very inquisitive kitten already.

Well we think she is on the track track if she’s interested in QRP! We have a history of felines who enjoy field radio. Thank you so much for sharing, Steve! She’s a cutie!
