Getting Started with HF Digital Modes – Without Breaking the Bank

by Joe (N0LSD)

Amateur radio can be an expensive hobby:  the reasons are myriad, made more difficult for newcomers because they tend to not have the experience to know what their requirements might be.  Brick-and-mortar stores where one might bounce ideas off knowledgeable staff, browse the aisles, and walk away with a suitable set-up are pretty few and far between.  Similarly, asking on various internet forums will often be met with, “It depends…” –followed by a wall of text filled with jargon and terminology that can be…intimidating.

For newcomers that maybe don’t have the time to invest in learning CW right off the hop, and perhaps get a bit of mic fright, digital modes such as FT8, JS8, and the like tend to be a great fit.  While “shack-in-a-box” solutions by the big-name manufacturers offer convenience, this convenience comes at a price that can be cost-prohibitive.

What follows is a QRP digital modes kit that I’ve experimented with over the last year.  No single piece of this kit cost more than US$150, and the entire kit can be had for under US$600.  What’s more, nearly everything can be purchased from Amazon.

We’ll start with the most expensive part of this kit:  the radio, which is the Tr(u)SDX.  It can be had on Amazon for US$138, and covers 20m, 30m, 40m, 60m, and 80m bands.  It is a quirky little radio with a sub-par speaker and a tiny little microphone.

The Tr(u)SDX is just about as bare-bones as one can get with an HF transceiver, and is decidedly a compromise.  However, unlike other ultra-compact transceivers, this one will do CW, it will do voice, and it will do *any* digital mode.  It can run on USB power at 1 watt output (micro-USB port on the side of the case); but it can also run on 12v (nominal) power via a 5.5mm x 2.1mm barrel connector on the top of the unit.

I’m powering this radio with a US$43 battery bank (Romoss Sense8P+), and a USB-C to 5.5 x 2.1mm cable (US$8.99) –both available on Amazon.  This battery bank will keep the Tr(u)SDX going for hours –long enough to do multiple POTA activations.  And, because there’s no special adapters, the battery bank can be re-charged in the same manner as a cell phone –or even off a small solar panel.

The sound card interface is the Digirig (US$57) with a US$19.97 cable that is TRRS 3.5mm on one end, and breaks out separate Mic and Speaker 3.5mm TRS.  Now, I will say that a recent firmware revision on the Tr(u)SDX has been demonstrated by the developers of the radio to allow for audio through the micro-USB connector of the radio – so the use of a sound card interface *may* be redundant.  However, in viewing the demonstration video for this, it seems rather dependent upon finding the right micro-USB to USB-A cable; with no clear indication on where one can obtain a cable that meets the specification.  Now, add a USB-C to USB-A or a USB-C to USB-C cable to interface with the computing device, and we’re in business!

So far we have a radio, power, and a way to get sound in and out of the radio.  Now, let’s talk about antennas.  Of course, one can homebrew an antenna for the cost of parts and time in construction and testing.  For the kit I’m using, I went with the N9SAB OCF Dipole –specifically because I do a lot of 80m QRP work.  Also available from N9SAB is a 6m-80m random-wire end-fed for US$89.99 from his eBay store.

If using a non-resonant antenna, an antenna tuner will be needed:  I went with the ATX-100 (US$126 from Amazon).  The reason I went with this is because it recharges with USB-C, which is consistent with everything else in this kit.

For coax, I personally use Times Microwave LMR-240 –a 50-foot length terminated in BNC is US$65 on Amazon.  For something less bulky, perhaps RG-316 from ABR Industries (abrind.com) might fit the bill  The ABR-240 coax at 50-feet in length is US$58.  For a jumper from the tuner to the radio, I use a 3ft RG316 cable from Amazon – which cost me US$13.99.

All that’s left is a device to run software…this can be a Raspberry Pi, or one’s laptop, certainly –however, these are bulky and require special power…and are a pain to re-charge easily.  Another solution is something one might already have:  an Android smartphone.  There are apps (some free, some paid) for RTTY, PSK31/63, WSPR, SSTV – these have been out for some time.  Additionally, one can do many of the modes contained in FLDigi, using the AndFLMsg app (not available on the Play Store –one has to download the .apk file from a 3rd party).  However, what I’ve been using –especially on POTA activations – is FT8CN.  This allows for full-function FT8 using just an Android phone –which can also be charged via USB-C.

DigiRig MobileSoundcard Interface $49.97 digirig.net/store
uSDX Cable for DigiRig Mobile $19.97 digirig.net/store
Total $547.86

This kit is –for sure– a compromise:  one isn’t going to bust pile-ups or win contests with it  However, for a “starter kit” that can easily be carried in a small backpack that can not only be used for HF digital modes, but also can do SSB voice and CW, it will at least get an operator on the air and enjoying the bands –without breaking the bank.

16th Floor QRP: Coffee break portable at the office

13 Comments

Many thanks to Bill (KG4FXG) who shares the following guest post:

Return to the Office:  Operating portable during coffee breaks (Atlanta to England)

by Bill Carter (KG4FXG)

Have you ever thought about operating from your work location?  Perhaps during lunch or a coffee break?  What if that location was downtown in a big city?

In my case, I work in a 17 floor Skyscraper.

The building has several large outside balconies on the 5th, 10th, and 17 floors.  There is also a green space on the 5th floor that is a grassy area with a lawn and trees.  What are all the possibilities here for portable operation? Let’s find out!

Amateur Radio is about learning, and to that end we may build antennas, perhaps QRP Rigs, and other things.  I’ve been building many QRPGuys and Tufteln antennas.  I also use a few that I’ve purchased, such as the Chelegance MC-750, AX1, Gabil Vertical Antenna GRA-7350TC [gear links below].

Sometimes, the weather does not play nice and I’m forced to try operating indoors.  Here I am using the Chelegance MC-750 on the 16th floor where I have clearance all the way to the top of the 17th floor.

The antenna almost touches the ceiling on the 17th floor.  I was able to make a contact in England: John G4RCG.  His location was in Kirkhamgate, Wakefield–about 11 miles from Leeds. We were able to exchange names but that was about it on 20M.

This antenna is amazing, I can’t wait to try it outside in our green space.

I was using the Elecraft KX2 but I have several QRP Rigs that I have brought to the office.  Such as the Norcal 40, Elecraft K1, both of which were kits I built.  I started QRP back in 1999 before there was POTA.  Back then, you had to build your radio.  Most did back then.

Learning about propagation has been interesting.  It is not ideal to operate indoors.  One simple way I test conditions is to see if I can hit the reverse beacon network.

Here’s a screenshot of the Reverse Beacon (below) while I was using the Chelegance MC-750 on 20 meters:

(Click to enlarge)

Simple Office Setup

I work for the railroad.  You will notice my mug says Taggart.  Some humor here, but that is from Ayn Rand’s Atlas Shrugged.  Story about a railroad and so much more.

Here is the Green Space on the 5th floor.  Could you use this space for portable operations?

Here is pictured where I operated off the 10th floor balcony.  The view is amazing!

For the balcony, I just throw a wire over the glass railing.  The balcony is huge with many tables and chairs for lunch.  I have used K4SWL’s Speaker Wire antenna build here.

My hours are very unusual.  I normally work from 2AM to 5PM and I leave to drive home at 11AM.  I love telecommuting for work these days.  So, when I operate, it is around 3AM or 4AM.  Not ideal times for POTA, but a great time of day to work DX!

I have so much more to try.  I have a Spiderbeam Pole and SOTABEAMS Pole that I am playing with as well.  I also have the Alex Loop Antenna that I will try from work.

Another operating position: here I am inside running RG-316 through the door to the 10th Floor Balcony.  I am using Thomas’s Speaker Wire antenna here.

One of the challenges that I face at 3AM is cold temperatures and wind.  There can be wind around these large buildings that can make operating difficult.  In cases of cold weather, I just opt for the little table and chair next to the door.  Besides, the coffee stays warmer longer inside!

New buildings make it very difficult if not impossible to get an RF signal out.  Getting an antenna outside is key.  And even then, that does not guarantee success.  The building’s corners have glass conference rooms.  You feel like you are outside, but I haven’t found a really good location for QRP.  That said, there are many more options to try.

Have you tried operating from your work location, perhaps at lunch?  Maybe as a POTA chaser?  What is your go-to method and set up?  Check out more of my shack on QRZ.

The POTA Babe Goes Back to Florida – Day 1

5 Comments

In pursuit of my 60 new-to-me park activations, I headed back to Florida for six days the first week of April. The weather forecast looked promising – high temps in the upper 70s falling to the upper 60s by the end of the week. Rain might dampen my spirits on Wednesday but otherwise, the sun was likely to shine during my journey.

Day 1 of my April 2024 Florida Trip

Daisy and I packed up the car and headed out early Sunday, May 31st. It was an easy journey – three and a half hours south down I-95 and then southwest across Florida. Of course, we stopped at the Florida welcome center and got our picture snapped, this time just the two of us.

Here we again in Florida!

We arrived in Branford which actually did look like a nice place to live. Lafayette Forest Wildlife & Environmental Area (US-6315) is just outside the town. Unlike the wildlife management areas in Georgia I’ve visited, this one looked more manicured. The road into the park could have been the entrance into some genteel Southern plantation.

Not far inside, we found a fenced-in parking area and kiosk. I figured this would be the easiest place to set up. Checking the kiosk, I confirmed we were out of hunting season though we would still wear our blaze orange items for our walk after the activation. (Before we arrived at the park, we actually saw a turkey crossing the road.)

I opted to use the Chelegance MC-750 on the tripod mount because I need more practice with it. That proved to be a good choice as I had to re-read the instructions to set it up – hi hi. This is what happens when you don’t use equipment on a regular basis.  Continue reading The POTA Babe Goes Back to Florida – Day 1 →

Kansas City to the Countryside: N5DUX’s Work Trip POTA Journey

8 Comments

Many thanks to Tommy (N5DUX) who shares the following guest post:

Work Trip POTA

by Tommy (N5DUX)

I recently had a work trip that took me to lovely Emporia, Kansas – home of Emporia State University. Prior to leaving for the trip, I did a little POTA sleuthing to see if there were any parks in the general region I could activate after I finished work each day. As luck would have it, I found there were indeed a handful locations on the POTA map within a reasonable drive – including one right in town!

One of the locations was a fun looking site called the Tallgrass Prairie Preserve National Conservation Area (US-3673), home to a herd of bison.

Viewing on Google Maps I saw a “scenic lookout” in the middle of the prairie and figured that sounded like a great place to setup.

Packing my suitcase for the trip (there’s work to do, remember!) I included my Buddistick and a collapsable, “450cm” carbon fiber fishing rod. The rest of my kit was in a hand held bag that I would carry with me. My main radio for this activation was my Elecraft KX2.

For an antenna, I brought my a newly built 20W K6ARK EFHW trimmed which I had tuned to work on 40m, 20m, and 10m with the idea of using the fishing pole to hold up the far end of my end-fed. Should that fail or disappoint, I had my Buddistick which is self-supporting thanks to the excellent design of its shock-cord tripod and “tie-down” to keep the whole thing upright in strong winds.

Included in my bag was a 9Ah Bioenno battery, reel of kite string, a throwing weight, notebook for logging, pencil, Elecraft hand mic, Elecraft paddles, some earbuds, and a few other insignificant odds and ends (adapters, pigtails, etc)

When packing radio equipment in your suitcase, remember to not pack any batteries in your checked bag. For carry-on, remember to not pack any pointed objects like tent stakes, screw drivers, or spikes like some vertical antennas like the Chelegence 750 or PAC-12 have. Pack smart – think about what the radio will look like to someone unfamiliar with our hobby.

TSA really doesn’t care about our radios or wires – they just don’t want bricks of organic material surrounded by wires on the plane or sharp pointy things in the cabin.

On Easter Sunday, I flew into Kansas City, picked up a rental car, got a quick bite of BBQ recommended by the guy at the rental car place, and set off. The weather upon arrival was excellent. A nice breeze, sun shining, and warm temps. Lovely. But the weather forecast had told me it wouldn’t last.

While at work on Monday, the temperature began its steady slide as a cold front moved through the area. As soon as the work day was finished, I quickly changed clothes and headed west of Emporia for the Tallgrass Prairie Nature Preserve.

The weather continued to get cooler and the wind had picked up.

As soon as I arrived, I was greeted by a park ranger leaving. I asked about the bison herd and he told me the scenic overlook I’d picked as my destination was a couple miles down a gravel trail. I ask the ranger if he knew about ham radio and he said there was a group coming in a couple months or something but said I was welcome to setup wherever I pleased. I grabbed my gear, preparing to make the 2 mile hike, and started down the path.

I got about a quarter mile in and cresting the first grassy rise, I realized I’d underestimated just how strong the wind really was and how cold it was going to get if I stayed exposed. I had not worn my thicker coat and realized I wouldn’t last long on the prairie given my attire and the weather to come. Seeing the bison would have to wait.

I changed course and walked back to a historic ranch situated on the property with some still-used cattle pens. Surveying my options there, I spotted a shelter for the livestock over in the corner of one corral. Eyeing the grassy area in that pen, I decided that was going to be my operating position. No sooner had I chosen my spot when I heard the faintest tick of raindrops hitting the tin roof.

I unfolded my chair in the dirt under the roof then unpacked my radio, pencil, logbook, some trail mix (nabbed from the hotel front desk snack bin), and my water bottle. I unspooled the EFHW and erected the fishing pole to hold up the far end. I connected the antenna and let the Elecraft KX2’s internal tuner do its thing. It found a 1:1 match in no time and everything was set.

Shack in the lap with the KX2.

I dialed through the band to get a sense of conditions on 20m. I listened to a few other POTA stations and was able to work them. I then found an unused frequency, called out, and listened. Nothing heard – I was ready to go. By this point, it was only about 30 minutes total since my arrival – not too bad.

I spotted myself on the POTA site and my first hunter responded to my CQ pretty quickly. This trend continued unabated for quite some time.

When there was a lull in activity, I grabbed a handful of trail mix and was mid-chew when someone called. I tried to swallow and got choked. He’s calling me. I’m trying to clear my throat. Nobody’s around – the best I could muster was a half-wheezy reply to his call. He probably thought my signal dropped a few dB – no old man, it was my voice. A splash of water after we were clear and I was back to normal.

Looking southeast from my activation spot at Tallgrass Prairie Nature Preserve in Kansas

Around this time, the raindrops decided to spit a little and the wind had definitely picked up. I adjusted my antenna to see if that helped matters. I used my kite string to secure one end of my wire antenna to the stone wall surrounding the pen and moved the fishing pole support from the end near the wall more toward the middle This gave the antenna more of an inverted V configuration.

It actually helped! Whereas before my “sloper” was more of a “sagger”, I actually got an increase in the relative frequency of QSOs. I worked with this configuration for the rest of my stay at the preserve. The wind never let up and the temps continued to slide. I was shivering by the time I finished packing up and the sun had set and darkness was setting in.

Back to the rental car and heater, please!

Tuesday brought a similar workday but I planned to activate a historic home there in town after enjoying a dinner at a local restaurant recommended by my hosts. The weather was considerably colder than Monday and it was downright windy. I’m glad I’d worked the nature preserve on Monday and didn’t wait to try on Tuesday!

Rental car portable at the William Allen White House known as “Red Rocks” in Emporia, Kansas

I made my way over to the William Allen White House State Historic Site (US-9183) a few blocks from the university and the dinner spot. With the weather as it was, I opted to sit in the rental car and run my antenna out the top of a cracked window over a couple low branches and over to another large tree branch. I got my rig setup in the car for my first “rental car portable” activation and found it to be considerably more comfortable than the night before. I managed to log about 20 QSOs in short order on 20m until band conditions deteriorated.

On Wednesday, we wrapped up the work project that had brought me to town. We had a final wrap-up meeting with my point of contact there and I headed back to Kansas City. The intent was to grab a quick dinner with a friend, head for the hotel, throw down my stuff and make for the World War I Museum National Memorial (US-4591). The dinner lasted much longer than I’d planned but it was okay. Dinner was with my CO whom I hadn’t seen since I was in the Guard.

We shared a great dinner with his wife, recounting funny stories from our times together and generally getting caught up. I didn’t get to the hotel until very late so I decided I better get some shut-eye and just activate the Museum and Memorial in the morning.

Thursday morning, I packed up everything to get ready for the airport.

My plan for the WW1 Memorial was to find a tree and throw the EFHW there and get some sun while sitting at a park bench or something. It didn’t happen. The strong, cold wind continued. I opted for another “rental car portable” operation. Noticing my “sloper” was again a “sagger,” I pulled the fishing pole out of my suitcase and elevated the antenna wire in the middle. Much better.

A view of the National World War 1 Museum and Memorial in Kansas City, Missouri

Band conditions on 20m were rapidly going down the drain and it was hard for me to hear anyone – the big guns that I worked toward the end of my activation provided such poor signal reports, I knew my QRP signal just couldn’t compete with the noise floor that continued to come up.

In total, I managed to bag about 14 QSOs in short order – but it was enough to count as another activation! And, since this was on the Missouri side of Kansas City, it gave me a new state.

I packed up, grabbed some more famous Kansas City BBQ at another local haunt, and headed for the airport to fly home.

The reliable, trusted Buddistick surprisingly never saw the light of day on this trip. It sure was along for the ride, but the EFHW really worked well and I enjoyed the simplicity of it when it came time to pack up. Being less of a compromise antenna led me to believe it would be more efficient anyway.

I’m still somewhat new to POTA and I continue to learn – but this was a memorable work trip because I brought my radio along with me and it took me to some spots I may not have otherwise ventured to visit. The work that brought me to the university went well enough that we began scheduling a return trip slated for sometime in a couple months. I plan on bringing my radio with me for that and on all future work trips in other places.

Handheld SOTA DX and Testing K6ARK’s New KH1 Pressure Paddles!

5 Comments

On Tuesday, March 12, 2024, I woke up with SOTA (Summits on the Air) on my mind.

That morning, I plotted to activate a local drive-up summit I’ve basically ignored the past few years.

Peach Knob (W4C/CM-097) is one of the most popular summits in the Asheville area no doubt because it’s so accessible. That said, it’s also a cell phone and water tank site with limited parking. When I first drove up a few years ago, there was a crew working and I would have only been in the way had I opted to activate. Also, to truly be within the activation zone on Peach Knob, there’s really only one small portion of the site where you can set up. Most of the summit is on private land.

I do SOTA primarily for the hikes. I’m not aggressively chasing activation points (ahem…obviously!) so I tend to ignore drive-up sites that are cramped and a bit awkward. Someday, I’m sure I’ll eventually hit Peach Knob just to do it, but that Tuesday? Yeah, I quickly decided I wanted a hike too.

I had a window of about three hours to fit in a SOTA activation. For POTA (Parks on the Air), that’s a generous number–I could easily hit three POTA sites in that amount of time, but SOTA takes more time. Typically there’s a longer drive to a trailhead, then a round-trip hike to figure into the planning as well. I immediately thought of one summit that would fit the bill.

Bearwallow Mountain (W4C/CM-068)

Bearwallow isn’t a long drive from downtown Asheville–maybe 20-25 minutes one-way. The hike to the summit is also fairly short and most enjoyable. The activation zone is the opposite of Peach Knob; it’s massive!

I arrived at the trailhead around 12:30 local and found that there were very few people parked there–-after all, it was a random Tuesday mid-day!

I’d packed my Elecraft KH1 field kit with the intention of doing a fully pedestrian mobile activation. I also had another goal: to test a prototype KH1 pressure paddle Adam (K6ARK) sent me to thoroughly test. I felt there was no better way than to SOTA with it!

Funny, but when operating pedestrian mobile with the KH1, you need so little extra kit. In fact, I could just grab my Pelican M40 case containing the full kit and be ready to go. But I always carry a first aid kit, headlamp, water, and other emergency supplies even if the hike is short and easy. Even if I have no need of those supplies on a short hike, someone else may. Twice, I’ve given other hikers first aid supplies from my pack.

Also, since I planned to film this activation, I needed to carry my camera, mics, and a tripod. I chose one of my favorite day packs: The GoRuck GR1!

My activation video, below, includes a bit of the hike and the contents of my backpack as I set up the KH1.

I decided to start this activation on the highest band the KH1 can serve up: 15 meters. After a delayed start (due to phone calls), I began calling CQ SOTA and the contacts started rolling in. It was funny–my first two contacts mirrored a previous Bearwallow activation: Christian (F4WBN) and Michael (N7CCD) in the same order! Within three minutes, I’d logged the four contacts necessary to validate the activation. Continue reading Handheld SOTA DX and Testing K6ARK’s New KH1 Pressure Paddles! →

My first POTA Activation with the Index Labs QRP Plus Field Transceiver

18 Comments

Sometimes, we do things for the pure nostalgia of it all!

I mentioned in a previous post that I recently acquired a circa 1995 Index Labs QRP Plus transceiver. Being transparent here, this was an impulse purchase fueled by pure, unadulterated nostalgia.

The QRP Plus was the first QRP transceiver that I’d ever laid my eyes on only a month or so before obtaining my ham radio ticket in 1997. I’ll write about this in more detail in the future–and I speak to this in my video below–but let’s just say that this little cube of a radio made a big impression on me at the very beginning of my ham radio journey.

I thought it might be fun to take it to the field and compare this 1995 state-of-the-art radio with so many of my other field radios. The QRP Plus wasn’t a perfect radio, but it was a marvel at the time it was produced. I can’t think of a smaller, more battery-efficient general coverage 160-10M QRP transceiver at the time.

I was eager to introduce this little radio to the world of POTA so on the morning of Thursday March 21, 2024, I grabbed it and hit the field!

Zebulon B. Vance Birthplace (US-6856)

I called the Vance site that morning and learned that a large school group would be arriving around noon. Since I was planning to leave around that time anyway, it was perfect timing for me.

Since I hadn’t created a field kit specifically for the QRP Plus yet, I brought my watertight stackable Husky brand box that basically contains everything I need to set up a field radio station, save the radio.

I unpacked everything I needed: a key, key cable, battery, power cord, cable assembly, antenna, logbook and pencil.

Since the QRP Plus has no internal tuner, I paired it with my MM0OPX 40M EFHW antenna which would give me 40, 20, 15, and 10 meters. Note that Index Labs used to make an external manual ATU for this radio called the QRP Companion–I’ve never seen one in person, though.

Even though the Vance staff told me that the school group would not be using the picnic shelter, thus I could have free reign, I still deployed my antenna in a way that it would not become a trip hazard–keeping it close to the shelter and as conspicuous as I could (I do wish I would have brought along my flagging tape, but I left it at home).

Setting up the QRP Plus station was quick and easy. Time to hit the air!

I started calling CQ POTA on the 40 meter band, hoping it would be a little productive while we were still in the latter part of the morning. Continue reading My first POTA Activation with the Index Labs QRP Plus Field Transceiver →

Planning a POTA Babe Trip – Part 2

9 Comments

(Note: I cut my Florida POTA trip short as I needed to take care of some personal business. I apologize for the change of plans and the inability to communicate that to y’all. I appreciate everyone’s support of the trip and the QSOs of those who hunted me. Articles will be forthcoming for those activations in the near future.)

Those of you who have followed my journey on QRPer know that I wrote an article about my kit for the trip I took last summer to Nova Scotia. Since then, what ham radio equipment I take with me has changed, partially because I am not flying to a different country far from home and partially because of my experiences with what I generally do and don’t need. I thought I’d share what my kit currently looks like for the spring-break Florida trip.

Here is a photo of what ham radio-related gear I am taking on my Florida POTA trip. We’ll first look at what I have in each section of the Elecraft bag I take with me and then a few items that do not fit in this bag but are still along for the ride.

When I purchased my KX2, I also purchased the Elecraft bag. Though the bag is bulky in its profile, it was a worthy purchase due to the amount of stuff it can store in one place in a well-organized manner.

The bag has three compartments.

In the first compartment is my main man, Craig, my KX2. He is the rig I use for all my QRP adventures out and about. I do have a protective cover I purchased for him but haven’t installed yet. I have a fear of messing with electronics and, though installing the shield isn’t rocket science, the project seems overwhelming enough that I haven’t tackled it yet.

Also in this first compartment are my throw bag containing an arbor line and throw weight, some S-carabiners, my homemade radials for the AX1, the tripod mount for the AX1, and a pencil and earbuds. I find I copy CW much better when I have a headset of some sort.

In this compartment, I used to have a back-up key. However, in its place is a new single-lever paddle from CW Morse [QRPer affiliate link]. I am using this key because it is wired to be a cootie or a paddle via an internal switch. I discovered my KX2 doesn’t balk at using this key like a cootie unlike when I use the CW Morse SP4. I desire to use QRP for more than POTA, specifically for SKCC and calling CQ for ragchews. SKCC requires a mechanical key and, as the cootie is my favorite key, this new key should fill the need  I discovered the last time I visited Skidaway Island.

In the second compartment, I have the AX1 and the Tufteln EFRW antenna. Those of you who have read my articles know I generally deploy the Tufteln EFRW antenna. On this April Florida trip, I plan to use the AX1 and the Chelegance MC-750 more often in preparation for my summer POTA trip. I anticipate I’ll be limited by terrain and park rules from deploying an antenna in a tree so more experience with verticals will be helpful.

In the third and final compartment are some odds and ends: neon pink flagging tape, an allen wrench for adjusting my CW morse keys, some twine, a short length of wire with an alligator clip on the end, two shock bungee cords, the cord for my CW Morse single-lever key, and a splitter for the headphone jack. I’ve used all these items (except the cord for the new key) at one time or another so I don’t want to leave the house without them.

Here are items I am also taking that don’t fit in the Elecraft bag.

The Tufteln kneeboard, POTA flag, and a notebook. I really like using pencil and paper for my POTA logs. I hold my key in the left hand and send with the right. For some reason, juggling that with paper is more manageable to me than logging in my phone or a laptop. The one thing I miss out on by doing that, though, is not knowing people’s names except those I’ve encountered many times. (And even then I forget names in the busyness of an activation so if I do, please forgive me.) I like to thank people by name at the end of the QSO rather than just their call sign if I know their name. I learned to do this in SKCC exchanges and I think it is a respectful and genteel practice. The one advantage I see to using a logging program is that I could do that with every QSO.

In a Tom Bihn bag, I have my RG-316 coax in three lengths (10’, 20’, and 50’), a short bungee cord, a stereo connector, and a newer version of the SP4 (aka The Minion).

Also coming along for the ride is the Chelegance MC-750. [QRPer affiliate link]

The last pieces of equipment I am bringing are for the first park I will visit – Lafayette Wildlife Management Area. In areas that allow hunting, Daisy and I wear blaze orange, even in the off season. Though as hams we try to be law abiding, we need to remember there are others out there who are not. When it comes to areas in which hunting is allowed, it is wise to wear blaze orange year-round because hunting violations due happen.

There you have it – the POTA Babe’s current QRP kit. I have one last question to address in this series – how I plan my trips. To find out, stay tuned…

Field Report: Elecraft KH1 for a Quickie POTA Two-Fer!

6 Comments

On Wednesday, March 27, 2024, I had a number of errands to run in town. Before leaving the house that morning, I looked at my schedule and honestly couldn’t see a wide enough opening for an activation.

In the latter part of the morning, however, I was miraculously ahead of schedule en route to a meet-up in Asheville. I decided to take a scenic route option along the Blue Ridge Parkway (US-3378). It was misty and foggy that morning; a beautiful time to drive the BRP.

Of course, any time I’m on the grounds or within the boundaries of a national or state park, it feels odd not to activate it (do you feel that way too–?) even though I drive the BRP.

I looked at my watch and realized I had about 15-20 minutes max to perform an activation.

I only had one radio in the car: my Elecraft KH1. I didn’t have any of my camera gear which was fine, because it would have been very difficult to set up a video and complete the activation all within 15-20 minutes.

I pulled over to quickly schedule my activation on the POTA website. I then drove about 5 minutes up the BRP to a larger pull-over with a short path to the Mountains To Sea Trail (US-8313).

Instead of setting up on the MST, I just walked down the bank and stopped within a few feet of the MST. This would yield an easy POTA two-fer!

I set up the KH1, sporting some new pressure paddles via K6ARK (one’s I’m testing), and I hit the air.

Gear:

I called CQ POTA and started receiving replies slowly. Well, in truth, it wasn’t that slow, but it felt like it when I was in such a rush.

After working five stations, I checked the POTA spots page and discovered that I had not been auto-spotted. Sometimes the connection between the POTA spots page at the Reverse Beacon Network is down. Indeed, several times lately, I’ve tried to activate when it’s been down–my timing has been impeccable.

I had a little mobile phone service, so I self-spotted and the rest of the contacts rolled in quickly.

I called QRT after logging 10 contacts with apologies to those who were still calling me. I had to get back on my schedule.

This quick activation did make me realize how the KH1 seems to be fitting into my POTA/SOTA routine.

I never intended going pedestrian mobile 100% of the time after I got my KH1. Instead, I find it to be the radio that gives me the most freedom and flexibility when I need it. The KH1 allows me to seize radio opportunities I’d otherwise miss.

In this case, setup and pack-up time was really no more than 40 seconds in total.  It took me a minute to walk down the bank to the spot next to the trail to do the activation. All the rest of the time was radio time. I feel confident that had I been spotted properly, I would have validated the activation (10 contacts) in less than 15 minutes.

It’s fun to realize you can play radio anywhere (almost literally) with a handheld transceiver like the KH1. It almost feels like cheating!

Eclipse Time!

As I write this post, I’m in our hotel’s breakfast area. We’re in Dayton, Ohio to view the total solar eclipse tomorrow. I hope to fit in a couple of activations– the only radio I’ve brought along for the ride is the KH1 (well, save my SW-3B Headrest kit).

Traffic yesterday (en route to Ohio) was pretty heavy. I imagine it’ll be much worse today and even crazier tomorrow.

We took a break from traveling, yesterday, to visit my father-in-law’s alma mater. Can anyone recognize this beautiful campus? Bonus points for correctly identifying it!

Our family is meeting up with Eric (WD8RIF) and his wife, so I’m sure we’ll manage to hit at least a couple of parks!

I must admit: it feels odd to be in Dayton a few weeks prior to Hamvention.

Maybe I should camp out at the Greene County Fairgrounds for the next five weeks just to be the first to grab a good deal in the flea market–!?!

Cabin POTA with the IC-705 and MC-750 at Gorges State Park!

13 Comments

As I mentioned in this previous field report, my buddy Mike and I spent the third weekend of March at Gorges State Park (US-2732) in Sapphire, North Carolina. We had a great weekend of hiking and just hanging out. Of course, I fit in a few activations!

On the morning of Sunday, March 17, 2024, after a nice breakfast and beautiful sunrise, we started packing up. Since we rented a cabin this year, it was an easy process–especially since it was also raining lightly. While I love tent camping, I’m not the biggest fan of packing up a wet tent and gear because later in the day I have to attempt to dry it all out back home.

The cabin also made it very comfortable to do a little Parks on the Air (POTA) until the rain passed and we could start our hike.

I set up my MC-750 vertical next to the cabin.

Inside, assuming I might have more radio frequency interference (QRM) to deal with, I chose my Icom IC-705.

The cabin had a small side table attached to the wall which was the perfect spot to set up my station close to the front door and porch. The weather was very temperate that morning, so I simply left the front door of the cabin open while I operated.

I was correct about the QRM: its pervasive throughout most of the park and is due to arcing on the high-tension power lines that run through the site.

Other than the QRM, Gorges is an amazing park to do POTA.

While I played Parks on the Air, Mike caught up on a book he was reading. Neither of us were pressed for time, so it was a pretty laid-back morning.

QRM Mitigation

After hooking up the IC-705 to the MC-750 and turning it on, the QRM was not only audible–that unmistakable frying sound–but it was clearly visible on the IC-705’s color display.

The noise level was about S5-S6 and persistent.

The IC-705 is a 21st-century radio and I decided to use some of its 21st-century, SDR-powered features in order to improve the audio.

First, I turned on the Noise Blanker (NB). While this feature works best for pulse noises (engine noise and electric fences, in my experience) it also removes a layer of noise from persistent arcing as well.

Next, I also used the IC-705’s built-in DSP (Digital Signal Processing). By turning on the DSP, another layer of noise is removed.

With both NB and DSP engaged, the audio was much more pleasant and less fatiguing.

Keep in mind that even though the noise was minimized in the audio, it was still there in the receiver so this didn’t help much with recovering weak signals under the elevated noise floor. It just made playing radio much more pleasant! Continue reading Cabin POTA with the IC-705 and MC-750 at Gorges State Park! →

John’s KH1 Redeems an Otherwise “Frustrating” Start to a Cross-Country POTA Rove

9 Comments

Many thanks to John (NS6X) who shares the following field report:

Frustrating rove from California QTH to OzarkCon in Branson, MO.

by John (NS6X)

I had great plans for a radio-centric, POTA activation road trip from my home in Camarillo, CA (outside Los Angeles) to my first visit to OzarkCon in Branson, MO. The Four State QRP Club hosts the two-day conference. I recently became a kitter (I put together one of the kits) for the club, assembling the parts and shipping the Cricket20 (see kits a 4SQRP.com).

I had the parks planned out along I-40 where I would stop, overnight stops for my little trailer, and my traveling companion Sachiko (Agnes), my Tortie cat.

Long story, but my wife of 48 years died three years ago from ovarian cancer, so I now enjoy traveling alone. I am calling my trip story, “Traveling with Agnes,” a shout out to John Steinbeck and Traveling With Charley. I seldom plan ahead, so to have night stops, parks planned, and such was something for me.

I packed my Elecraft KX2, KH1, FT-891, Penntek TR-35L, and my 22-year-old KX1. I have multiple Bioenno batteries for power, that I packed in an official QRPer.com/HRWB bag and placed next to the door.

I should have stepped out of the door and put it in my truck or trailer, as I left the batteries at home. I did have a Bioenno solar “generator”, but it doesn’t have power pole output connectors, and I haven’t made power pole-adapted cables for it. And of course, I left my power pole crimpers and connectors at home, too. I didn’t discover this until I stopped at my first POTA park, the US-1058, Homolovi Ruins State Park in Arizona, just outside of Winslow.

My KX2 had a partially charged battery, so after futzing about with the power sources, I set up my KX2 and AX1 antenna. I was able to make 7 QSOs in a little less than an hour, even after spotting myself, but did not have the time to stay longer to complete the activation. My campsite was at a KOA in Albuquerque; it was raining/snowing/hailing, and my next stop at the Petrified Forest was out, too. I was discouraged, so packed up and took off.

I had watched Thomas’, K4SWL’s videos and read about the KH1 being used as a radio for an activation, but after my limited number of contacts in Arizona, I wasn’t too positive about it. However, coming from a suburban lot in a housing tract, the lack of QRN/M noise in the Arizona desert was amazing. I didn’t think that I had turned on the radio, seriously.

So, driving through New Mexico, and part of Texas, into Oklahoma for the evening, stopping at a Harvest Host location for the night, I decided I would listen to the bands, using the KH1. I heard a few signals. My stop was only a few miles from the Washita County Wildlife Management Area, US-8661, so I decided to take the KH1 and mosey over to the POTA site.

I told myself why not, spotted myself on 20 meters at 14.058.2, called CQ and was I surprised. LOUD signals came back. Many stations were calling me. I completed my activation with 12 QSOs in 16 minutes, using the KH1, putting out 4.6 watts. The SWR was about 1.1:1. I was impressed with the stations from Wisconsin, Pennsylvania, Florida, Texas, Missouri, and North Carolina that called me. Did I say they were LOUD? And no noise.

I just finished the activation – forgot to take photos. I was a photojournalism major (although my career was as a firefighter and paramedic). How could I keep forgetting to take photos?

My takeaway and lesson learned was to pack ahead of time, with a checklist (I am never that organized), and that the KH1 is a real radio, able to do things like be used for a POTA activation.

It didn’t hurt that I had a zero noise level, and that there were QRO stations calling me, as well as the spotting system that makes POTA and other similar activities workable, and fun.

After becoming first licensed in 1966 at 11 years old, I am once again excited about ham radio. The social aspect of ham radio is a real positive. The fun of POTA and SOTA is invigorating my radio life. I am back contesting, and putting up a better antenna at my house: the CC&Rs are no longer valid as they haven’t been enforced for more than 35 years, no HOA, and the city issued a permit to me.

I will be back at another Oklahoma park in the morning. I am writing this in the early evening after getting back to my trailer. My KH1 battery is charged, ready to go, if anyone else is ready at 8 AM.

Off to Joplin, MO tomorrow, then Branson, MO for the conference on Thursday, beginning Friday morning. The conference is over Sunday. I did make a reservation for Sunday night in Branson to hang over and watch the eclipse as the sun passes over Branson on Monday.
