One of the funny things about doing field activations is you never know what to expect when you arrive on site, setup, and hop on the air. It’s part of the fun, really. There are certain things you can control, and then there’s propagation.
On Sunday, February 14, 2021 (yes, Valentine’s Day), we had a modest break in the weather and my wife and daughters encouraged me to hit the field to do a quick activation before an afternoon movie marathon. Sunday was the first day I had seen the sun at our house since the previous Wednesday when the cloud ceiling descended to the altitude of our house (3,300′ ASL) and stayed there. It also wasn’t raining incessantly on Sunday, which was a welcome change.
I checked with my go-to propagation friend Mike (K8RAT) before heading out the door and he informed me that things were dismal. I wasn’t surprised: earlier that morning I worked a couple CW stations calling CQ POTA on 40 meters who had very few takers.
Still…I wasn’t going to let propagation stop me.
“Damn the torpedoes, full steam ahead.”
I chose the Zebulon B. Vance Birthplace (K-6856) as my POTA site because it’s the closest park to me that has a covered shelter. I fully expected rain to move in within an hour and really didn’t want that to cut my radio play short.
Once I arrived on site, I decided to deploy my Chameleon MPAS 2.0 vertical antenna. Why would I use a multi-band vertical instead of a more efficient wire antenna on a day with dodgy prop?
For one thing, I had a limited amount of time and the MPAS 2.0 can be deployed and packed up within a few minutes. Also, I could position the MPAS 2.0 close to the shelter so if heavy rain moved in, I could even keep the base of the antenna protected and pack it up under cover. That and I really didn’t want to fiddle with a wire antenna in the rain if I didn’t have to.
In short: I only made 12 contacts during this brief activation.
But what I lacked in quantity, I made up for in quality!
Let’s skip straight to the QSOmap of the activation. Keep in mind these are contacts made with a vertical antenna and only 5 watts of power (green poly lines are CW, red is SSB):
Days like Sunday we can’t expect large pileups with five watts, but we can expect normal–albeit brief–openings that allow for some serious low-power DX.
My five watts and a vertical caught Raffaelle’s (IK4IDF) attention in Italy. Sure…he has good ears with a nine element HF Yagi, but I worked him with 5 watts over a distance of 7653 km / 4755.36 mi.
951 miles per watt? Yes, please! I’ll take that!
Parks On The Air isn’t really about working DX, but it’s so much fun when it does happen.
Video
I made a video of the full activation which includes setting up the Chameleon CHA MPAS 2.0. As I mention each time, this is a real-time, real-life video so keep expectations low. 🙂 It includes a number of mistakes on my part.
I’m hoping this odd pattern of bad weather will break soon. I shouldn’t complain: I feel pretty fortunate that we haven’t gotten hit hard with some of the heavy winter conditions affecting much of North America right now.
As soon as it dries up a bit, I’m ready to hike to a local summit for a little SOTA (Summits On The Air) fun! I can’t wait…
Last week, I had a hankering to visit a site I hadn’t activated in a few months: South Mountains Game Land.
This game land is pretty vast and has a number of entry points, almost all of which are very accessible. When I re-visit a site multiple times, I like to try different entrances when I can because it gives me a chance to check out a site better and, frankly, even enjoy a little light off-roading.
I found a western road leading deep into South Mountains from the Wildlife Resource Commission map and decided to explore it and do a quick activation.
South Mountains Game Land (K-6952)
I avoid activating Game Lands on days when I suspect there will be a lot of hunting. Tuesday afternoon was *not* ideal for hunters. Besides being the middle of a work day, it was cold and very gusty.
As I drove about 4 miles into the site, I didn’t see a single car or truck parked in any of the parking areas. I could tell I had the place to myself.
A Few Precautions
It goes without saying that if you’re doing a POTA or SOTA activation in a rural/remote area that has no mobile phone coverage (quite common at the ones I activate), you really need to take a few precautions.
First of all, let someone else know where you’ll be and how long you plan to be there. I always let a couple radio friends know where I’ll be so if I don’t show up on the air or they don’t hear from me, they could contact authorities to look for me.
Secondly, always take a proper first aid kit. If you get hurt, you need a way to apply first aid until you can get help.
Take a handheld radio with local repeater frequencies pre-loaded. Even though I might not have cell phone coverage, I can almost always hit at least one repeater.
Of course, carry a little food and water with you and make sure your vehicle has fuel as well.
Always wear a high-visibility vest, jacket, and/or cap. Many game lands require these. Besides, would you rather perform and activation or get shot? I don’t like getting shot. I also don’t like the idea of being bear food, so at least pack a little bear mace if you’re in bear country.
When I’m activating a game land I don’t hike deep into the woods. In fact, I try to stay on or very close to a parking area. Even though POTA is becoming a very popular radio activity, I can promise that you’ll likely be the first POTA activator most hunters will see. It’s a good idea to be near areas of activity like a parking spot or road where they’re much less likely to be hunting.
Finally, as I mentioned before, I personally do not activate game lands on busy hunting days.
Of course, check the weather forecast in advance.
On The Air
I found a great spot to set up my station near a ridge line deep in the game lands.
Normally, I’d set up right next to my car, but Tuesday the winds were very gusty so I found a semi-protected area maybe 10 yards off the road. I located a spot with the least amount of overhanging branches (always check for widowmakers and dead trees!).
It only took me five minutes to deploy the Chameleon Emcomm III Portable random wire antenna with my arborist throw line.
Random wire antennas require tuners, so I employed the Mat-Tuner mAT-705 Plus.
This site has no mobile phone coverage, so I had no easy way to spot myself to the POTA spots page had I decided to do a little phone/SSB operating. I decided to stick with CW as the POTA spots page will auto-spot me using my information from the Reverse Beacon Network (as long as that system is working).
It’s so rare that I do activations around noon or early in the afternoon, so I decided to start on 20 meters just to see if I could snag a European station.
I felt pretty chuffed to quickly snag the Azores (CU3BL) and a few west coast stations with my 5 watts and a wire. QRP rocks!
I then moved to 40 meters where I worked a number of stations in succession and topped off the activation with one 30 meter contact.
Here’s a QSOmap of this activation:
Not bad for about 40 minutes on the air.
Video
I also made one of my real-time, real-life videos of the activation. Note that my camera died on me perhaps five minutes before I completed the activation, so it will end abruptly. Sorry about that!
My ankle is healing nicely so I’m feeling more comfortable with the idea of hiking again. I’m plotting a SOTA activation with my daughter in the coming weeks.
This Saturday (Jan 30, 2021), I had a small window of opportunity to perform a Parks On The Air (POTA) activation. My park options were limited because I needed to stay near my home and a store where I was scheduled to do a curbside pickup.
The only viable option–since time was a factor–was my reliable quick hit park.
The Blue Ridge Parkway (K-3378)
I plotted a quick trip to the Blue Ridge Parkway Folk Art Center which is centrally-located and, this time of year, there are few visitors.
But what radio take? It had been a couple of weeks since I used the IC-705 in the field, so I decided to take it and rely only on its supplied BP-272 battery pack.
My buddy Mike (K8RAT) had warned me only a few minutes before my departure that propagation was pretty much in the dumps. I’d also read numerous posts from QRPers trying to participate in the Winter Field Day event and finding conditions quite challenging.
Saturday was the sort of day that I should’ve deployed a resonant wire antenna and made the most of my meager five watts thus collect my required 10 contacts in short order.
And that’s exactly what I didn’tdo.
You see, a really bad idea popped into my head that morning: I had a hankering to pair the IC-705 with my Elecraft AX1 super compact vertical antenna.
This made absolutely no sense.
I tried to get the idea out of my head, but the idea won. I suppose, at the end of the day, I’m not about taking the easy path (and I’m obviously a glutton for punishment).
I was also very curious if the mAT-705 Plus external ATU could tune the AX1 on 40 meters. More on that later…
I arrived on site a few minutes before noon. Setup was fast–that’s the big positive about using the AX1.
Normally, I deploy the AX1 antenna with my KX2 or KX3 and simply attach it to the BNC connector on the side of the transceiver. The AX1 Bipod gives the antenna acceptable stability during operation.
The IC-705 also has a side-mounted BNC connector, but it’s much higher than that of the KX3 or KX2. I’m not entirely sure I could manipulate the Bipod legs to support the antenna without modification.
That and the AX1 needs an ATU to match 40 meters (where I planned to spend most of the activation). Since the IC-705 doesn’t have an internal ATU, mounting it to the side of the transceiver really wasn’t an option.
I employed my AX1 tripod mount for the first time. On the way out the door, I grabbed an old (heavy) tripod my father-in-law gave me some time ago and knew it would easily accommodate the super lightweight AX1.
On The Air
I first tried using the Mat-Tuner mAT-705 Plus ATU to tune the AX1 on 40 meters.
No go.
I tried both the phone and CW portions of the 40 meter band, but the mAT-705 Plus simply couldn’t find a match. SWR was north of 7:1 – 9:1.
Instead of grabbing the Chameleon MPAS Lite or 2.0 from the car, I decided instead to see if the Elecraft T1 ATU could tune 40 meters.
It did.
In short, I logged my ten contacts to have a valid activation, but it was slow-going. All but two of my contacts were on 40 meters CW. The last two logged were on 20 meters CW.
It was a challenge, but I really enjoyed it! And, frankly, considering the propagation, 5 watts of power only using the IC-705 battery pack, and the inherent inefficiencies using a loaded compact vertical antenna and ATU? I was impressed.
Here’s a QSOmap of my 10 contacts:
I bet my effective radiated power was closer to 2-3 watts.
Typically, the AX1 antenna acts almost like an NVIS antenna on 40 meters, but Saturday it favored Mid-Atlantic and the states of IN, OH, and PA. Normally, I would expect more of a showing from the states surrounding North Carolina.
My last two contacts on 20 meters were with KE5XV in Texas and KB0VXN in Minnesota. Not a bad hop!
It took longer to collect my ten contacts than I had hoped and I ran nearly 25 minutes late to my curbside appointment. I’m a punctual guy, but there was no way I was leaving without my ten! 🙂
Here’s a video of the entire activation. Hint: it’s the perfect remedy for insomnia:
Next time I try to pair the IC-705 with the AX1 antenna, I think I’ll try adding a couple more ground radials and see if the mAT-705 Plus can more easily find a match.
One thing I know for sure: the T1 is a brilliant little ATU. While the mAT-705 Plus was never designed to do this sort of match, it’s comforting to know the T1 can.
I’m very curious if anyone else has paired the Elecraft AX1 with the Icom IC-705 or other QRP transceivers. If so, what was your experience? Please comment!
Last week, I thoroughly enjoyed taking the Yaesu FT-817ND to the field.
While the ‘817 lacks features I’ve come to appreciate during field activations like voice and CW memory keying, it’s still an incredibly fun and capable radio.
Last Monday (January 18, 2021), I had an opportunity to visit Lake Norman State Park (K-2740) and perform an activation around lunchtime. Lake Norman is convenient to my hometown of Hickory, NC and these days I typically spend at least a couple nights there doing a little caregiving for my parents. It’s rare my schedule is clear at lunchtime to fit in an activation–typically it’s later in the afternoon.
As with my recent activation at Lake Jame State Park, I paired the Yaesu FT-817ND with my Par End-Fedz EFT Trail-Friendly 40/20/10 meter resonant antenna.
It was an incredibly fun activation and one of the few recently where I racked up some great QRP contacts across the 20 meter band before moving to 40 meters.
Here’s my QSOMap of the activation (red lines are phone, green are CW):
As with most of my activations, this one was relatively short. Rarely do I have more than 45-60 minutes of on-air time during a POTA sortie.
I also made another real-life, real-time, no-edit video of the entire activation. If interested, you can view it via the embedded player below or on YouTube:
I’m long overdue a multiple park run, so will start strategizing soon! The Parks On The Air program has also added a few new park in North Carolina, but none appear to be in the western part of the state.
Oh, and Phillip, thanks for prompting me to take the ‘817 to the field again. It is a gem of a rig and I think it might suit your needs very well!
One question that often faces newcomers to the hobby is: “Should I buy a QRP or a 100W transceiver as my first rig?”
That is a very deep topic, actually, and one to explore in a future post. A 100 watt transceiver will certainly give you more options as they can often pump out 100W or be turned down to 1 watt. If you’re a phone operator only, that’s got some serious appeal. Then again, if you’re operating POTA or SOTA where you are the DX, power–while still important–is much less so than, say, if you were at home trying to work DX.
Again, a deep topic for another post because there is no right or wrong answer.
One of our readers (Phillip) reached out to me a couple weeks ago and asked if the Yaesu FT-818 would make for a good first HF rig. He liked the portability factor, the build quality, the HF/VHF/UHF multi-mode coverage, and the overall flexibility of the rig as a field radio. His goal was to do POTA activations.
We had quite a few emails back and forth about the pros and cons and I decided it might make more sense to simply take my Yaesu FT-817ND (which is nearly identical to the FT-818) to the field and activate a park in both SSB and CW. Since I knew he wouldn’t necessarily have an external antenna tuner from day one, I paired the FT-817 with my resonant 40/20/10 meter end-fed antenna.
Lake James State Park (K-2739)
On January 17, 2021, I pulled into my favorite part of Lake James State park and quickly set up my station. I only had about one hour to complete my activation, so knew this would be a very brief excursion. Since I actually had a minimal amount of gear, it was a quick setup.
Since I deployed a resonant antenna, there was no tuning or matching involved which not only makes the most of your 5 watts (in that it’s more efficient), but also saves a bit of time in set up and tuning up.
I’m testing this prototype at the moment, but didn’t need to employ it at Lake James since it’s really useful when the rig is on your lap or on on the ground. It essentially gives you top-mounted controls and a larger display to read front panel information from above–incredibly useful for SOTA and proper in-the-field activations. Andy’s v3 board will include a memory keyer–I can’t wait for that one!
Since I had Internet access at this park, I used my Microsoft Surface Go logging tablet to spot myself to the POTA network. I started calling CQ on 40 meters phone (SSB) and within six minutes logged eight stations. Not bad for 5 watts and a wire!
Next, I moved to CW on 40 meters and started calling CQ POTA. The POTA spots page auto-spotted me via the Reverse Beacon Network in short order. In eight minutes, I worked six more stations.
I then moved to twenty meters which was essentially dead, so I called it quits a bit early. I needed to pack up and head to my next destination.
Here’s a QSOMap of this short activation (red polylines are SSB and green CW):
Truth is, each time I use the FT-817, I love it more. Sure it’s only 5 watts, has no ATU, has a small display, a clicky T/R relay, and questionable ergonomics, but it is a keeper for sure. Even after 20 years of being in production, it still holds its own and is an incredibly popular radio for good reason.
As I told Phillip, the 817/818 is the Toyota Corolla of the QRP radio world.
Last week, I activated Pisgah Game Land and Pisgah National Forest (K-6937 & K-4510)–things didn’t exactly go according to plan. I still achieved a valid activations–meaning, I logged ten contacts–but I cut my antenna too short.
In short: I cut my wire antenna too short and my KX1 and KX2 ATUs couldn’t find an acceptable impedance match on the 40 meter band. This pretty much forced me to make do with 30 meters and above unless I modified or switched antennas.
The 40 meter band tends to be my most productive band, particularly on days like last Saturday when I’m operating in the latter part of the afternoon.
Maybe it was stubbornness, but I was determined to make a valid activation with that four-feet-too-short antenna.
I first hopped on the air with my Elecraft KX1 (above) and logged a few contacts on 30 meters. I then tried 20 meters, but the band was dead.
Eventually, I pulled the Elecraft KX2 out of the bag with the hope it might actually find a match on 40 meters, but as I said in my previous post, that darn physics stuff got in the way.
That’s okay, though. Although the sun was starting to set and I didn’t want to pack up in the dark, I took my time and eventually logged ten contacts for a valid activation. I actually enjoyed the challenge.
I complain about my wire antenna, but in the end, it made the most of my three watts by snagging stations from New Hampshire, Ontario, Illinois, Arkansas and several states in between.
Against my better judgement, I made a video of this activation. As with all of my videos, they’re real-time, real-life, and have no edits. (They also have no ads.)
A few readers and subscribers had asked me to include the odd video where I actually do a full station set up including the installation of a wire antenna–that’s what you’ll see in this video:
At the end of the day, this was still an incredibly fun activation.
This was the first time I’ve ever completed a valid activation only using the 30 meter band.
Next time, though, you’d better believe I’ll cut my antenna to be the ideal length for 40 meters and above!
How long?
If you use a similar antenna with your KX1, KX2, KX3, or other transceiver, I’m curious what lengths you find work best for 40 meters an above. Bonus points for 80 meters. Please comment!
When my buddy Don told me he was selling his Icom IC-703 Plus a few weeks ago, he caught me in a (multi-year long) moment of weakness. I asked his price and followed up with a PayPal transaction without giving it a lot of thought. It was a bit of an impulse purchase, if I’m being completely honest, but he definitely gave me a “friends and family” discount. (FYI: Don is the same enabler that made this purchase happen.)
I’m thinking the IC-703 Plus might be a good first HF rig for my daughter (K4TLI) and, of course, it’ll be fun to take it to the field from time to time.
Of course, the best way to get to know a radio, in my opinion, is to take it to the field. So that’s exactly what I did last week (January 13, 2021).
Blue Ridge Parkway K-3378
Against my better judgement, I decided to make a video of the activation. I mean, what could possibly go wrong operating a radio for the first time in the field? Right–?
I picked out an “easy” park for this activation: the Blue Ridge Parkway.
Although most of the parkway around Asheville, NC, is closed to vehicle traffic, the Folk Art Center is open year round and a very convenient spot for POTA.
I paired the IC-703 Plus with my Chameleon MPAS 2.0 vertical antenna. I was curious how easily the IC-703’s internal ATU could match the MPAS 2.0: turns out, pretty darn well!
I started the activation on 40 meters phone (SSB).
Almost immediately, I logged a few contacts and that quickly built my confidence that even the default voice settings were working well on the IC-703 Plus.
I then moved to 40 meters CW and used the CW memory keyer to call CQ (I pre-programmed this before leaving the QTH that day).
Then I experienced a problem: when someone answered my call, my keyer didn’t work properly. For some reason, it was sending “dit dash” strings from both sides of the paddle. I’m not entirely sure what happened but assume there was either a radio glitch or a small short in my paddle cable. After fiddling with the IC-703 for a bit, I pulled out my Elecraft KX2 and finished the CW portion of my activation. (Always carry a spare radio, I say!)
Actually, I assumed since I was using the IC-703 for the first time, there could be hiccups as I did not do a full rig reset prior to putting it on the air–settings were essentially what they were when Don had the radio.
Here’s one of my real-time, real-life no edit videos of the entire activation, if you’re interested:
Back home, I connected my CW Morse paddles up to the IC-703 and it worked perfectly. Even though I checked the connections in the field, I must assume one of the plugs simply wasn’t fully-inserted. It hasn’t repeated this since.
Despite the CW snafu, I’m very pleased with the IC-703 Plus so far. I like the size for tabletop operating and it’s actually surprisingly lightweight.
If you own or have owned the IC-703, please comment!
I don’t know about you, but part of the fun of playing radio in the field are the inevitable frustrations.
It might not feel like it in the moment, but when I eventually overcome the challenges of a mistake, I feel like I’ve truly accomplished something.
That was my little epiphany this morning: making mistakes has perhaps made me a better radio operator. Less-than-efficient field deployments have honed my skills and had a major influence on the gear I pack.
If you’ve read some of my (rather rambling) field reports in the past, you’ll note that I rarely do field activations with the exact same gear combinations each time. I feel fortunate enough that I can pair different radios with different antennas and different accessories. I get a small thrill out of not knowing exactly how well a combination will work, especially if I’m not activating a rare all-time new park or tough summit for that matter. In cases where getting to the site is a challenge in and of itself, I want to use a trusted combo of gear.
It’s that wee bit of mystery that attracts me to the field.
If I approached POTA more like a contest–where activation and contact numbers were my focus–I would have installed a mobile HF rig in my car a long time ago. I could rack up way more parks and contacts that way. It especially simplifies multi-site activation days since it effectively eliminates the time involved in setting up and later packing up gear. Mobile operating is the most efficient way to hit number goals: drive up to a site, start calling CQ, work your stations, then move on.
K-6937 & K-4510
Yesterday, I did a last minute “two-fer” activation of Pisgah National Forest and Pisgah Game Land. I had not planned to do an activation that day–temps never rose above 29F (-2C) at the QTH day and it also snowed and flurried all day long. Winds were very gusty as well, so it effectively felt much colder on the skin.
I wanted to hike up to the ridge line behind my QTH and do the activation but I knew up there temps would be lower and (worse) winds much stronger. Cold doesn’t really bother me, but strong winds do. This was also the first weekend my ankle felt almost normal after twisting it badly last month. It’s healing and I hope will be in shape for a long hike from my QTH to a six point SOTA summit next weekend with my daughter (K4TLI).
All of those factors combined pointed toward simply staying at home, drinking coffee, and reading a book.
But I really wanted some outdoor time. And I really wanted to make an activation with my Elecraft KX1, so I decided that instead of hiking up in elevation 800 feet, I’d drive down about 900-1,000 feet to a forest trailhead. That would get me on the air in a protected valley with less wind, less snow, possibly warmer temps, and much less hiking which would be easier on my ankle.
The Last-Minute Antenna
When I use the KX1 in the field, I typically pack a very simple antenna: one length of radiator wire and one length of counterpoise wire–connected to a BNC binding post adapter, I let the built-in ATU sort out the match.
When I owned my first KX1, I had a magic length of radiator wire (the length of which I can no longer remember) that seemed to work amazingly well on 40, 30, and 20 meters.
My new-to-me KX1 came with two lengths of wire: one 23′ and one about 20′. Although I made a fun and successful activation with this setup, the radiator was simply too short for the KX1 to find a decent match on 40M.
On the way out the door, I decided to cut a new radiator and counterpoise out of scrap wire I use for antenna experiments.
Being a bit stubborn and also in a hurry to beat sunset, I did no Internet research to sort out the ideal lengths for 40 meters. I simply cut a 17′ length for the counterpoise and about 27.5′ for the radiator.
In the Field
After arriving on site, I deployed the antenna and tried finding a match on 40 meters with the KX1’s internal ATU.
No go.
I tried a few times hoping maybe the ATU would find something even semi-reasonable in terms of a match, but there simply wasn’t enough radiator to make it work. That was a shame because forty meters would have been the ideal band for yielding quick contacts this time of the afternoon.
I had options, but I wanted to make what I had work.
The activation took time and patience. The 30 meter band was now my best bet and it’s where I logged all ten contacts for a valid activation. I tried 20 meters where I had a 1:1 match, but the band was dead.
At one point, I switched out the KX1 with my KX2 that I also packed. I tried to find a 40 meter match with the superior KX2 ATU, but physics got in the way again. 🙂
40 meters was an option
Let’s be clear here: I could have easily cut 4′ off of the counterpoise and attached it to the radiator and I bet I would have gotten a match on 40M. Since the counterpoise was lying on the ground, its length was less crucial.
I also had a perfectly capable 40/20/10 en-fed antenna in my pack. Switching out the antenna would have only taken four minutes.
I bet I could have easily yielded 20 additional contacts on 40 meters because the band was in great shape. Almost without fail, 40 meters is my most productive band.
Working with limitations
Thing is, I’m starting to understand that I like working with self-imposed limitations.
Perhaps this is why I love QRP and low-power radio so much: I get a little thrill out of doing more with less.
Yesterday, even after I realized it would be a struggle to log my final three contacts on 30 meters, I persisted. One motivation was I’ve never completed a full activation using only 30 meters. With a little patience, I knew I could snag my ten contacts.
The only things making it a challenge were the facts that temps were dropping rapidly, winds were picking up, and the sun was setting. Hazel (the POTA dog) who so eagerly jumped in the car when she saw me put on my hiking boots earlier, was also starting to shiver.
Fortunately, after trying another short stint on 20 meters, I returned to 30 and worked two more stations in quick succession giving me a total of nine contacts.
It started to get darker, so I hunted and found an operator calling CQ on 30 and simply made contact with him. He wasn’t a POTA station, just a general CQ call. He kindly gave me his details for the logs.
Lessons learned
I made a video of most of this activation and will upload it when I have a little bandwidth to do so. I’ll embed it in a shorter field report here on QRPer since I’ve described so much already.
Even though it was a challenge making ten contacts to accomplish a valid field activation with my time constraints, I’ll admit that I really enjoyed the challenge.
Next time I head to the field with the KX1, I’ll actually test the antenna prior to leaving the QTH.
In fact, I’m planning to make two radiators: one at an ideal length for 40 meters and above, and another–much longer–for 80 meters and above. Any advice and personal experience from KX1 owners would be much appreciated.
Perhaps most importantly, it’s only now dawned on me how much I enjoy making the most with self-imposed limitations or “trying to make lemonade with lemons.”
Do you feel the same? I’d love to hear your comments.
While I tend to use small, field-portable transceivers on many of my Parks On The Air (POTA) activations, I also love using tabletop transceivers when I have a picnic table available or decide to use my portable table. Tabletop radios often provide more power output when needed and better audio from their built-in speakers.
Although I have an Icom IC-756 Pro transceiver, and an Elecraft KXPA100 amplifier that I can pair with my KX2 and KX3 (or any QRP transceiver for that matter), my favorite tabletop fiel;d radio at present is the Mission RGO One 50 watt transceiver.
In short: it’s a brilliant, simple, tabletop transceiver that’s very happy in the field and a pleasure to operate. My RGO One has the optional built-in antenna tuner (ATU). The rig designer is allowing me to keep this unit on extended loan as I help him evaluate and test updates and upgrades.
While I’ve used the RGO One on numerous POTA activations, I don’t believe I’ve ever made a video of it in use, so I decided to change that last week with another one of my real-time, real-life, unedited (lengthy!) videos of this activation (see video below).
Lake Norman State Park (K-2740)
As I’ve mentioned before, I love activating Lake Norman State Park because it has numerous spots for setting up my gear. While I actually prefer activations that require a bit of hiking, it’s nice from time-to-time to activate a state park that has so many widely-spaced picnic tables under tall trees. That, and my right ankle is still healing after I twisted it in December, so I’m avoiding any proper trail hiking until it is better.
I made this activation of K-2740 on January 4, 2021.
Since I have Internet access at Lake Norman, I can check out the POTA spots page on my phone or tablet and self-spot as well as see spots of other activators.
When I have Internet coverage like this–and I’m not pressed for time–I try to work as many Park-To-Park contacts as I can before I start calling CQ POTA myself.
As I mention in the video, one of my 2021 goals is to obtain a valid activation of each park with only five watts or less. This means that each time I start an activation, at least my first ten stations logged will be with a max of five watts of power. I would actually make the goal for all of my 2021 activations to be 100% QRP, but I evaluate gear regularly and part of that process is to push wattage limits so it’s simply not realistic.
This isn’t actually a crazy goal because a number of my transceivers max out at five watts or less, and I know it won’t be an impediment as I activate parks in CW.
In SSB, though? It makes it a bit more challenging, but certainly not impossible and I’m always up for a challenge!
So I started this activation by trying to work a few Park-To-Park contacts but first cranked the RGO One power down to five watts. Trying to be heard over other hunters in SSB was difficult, but CW was much easier.
After working a few P2P stations, I started calling CQ on the 40 meter band in SSB. I worked about four stations, then switched to CW and worked seven more on 40 meters.
Since I’d snagged my ten contacts for a valid activation, I moved up to 20 meters phone (SSB), cranked up the power to over 40 watts, and started calling CQ POTA and racked up an additional 11 contacts for a total of 26 contacts logged at this activation.
Here’s my QSOmap:
Note that I left the callsign labels off the map this time to make it a little easier to see the geo location of the stations I worked.
Typically, there’s a trade off with field antennas:
High-performance antennastend to take more time to install. Some of my highest performance antennas are dipoles, doublets, delta loops, and end fed wire antennas. All of them require support from a tree if I want maximum height off the ground. Some (like the dipole) require multiple supports. While I actually enjoy installing wire antennas in trees, it typically takes me at least 10 minutes to install a wire antenna if it only needs one support and one counterpoise.
Compromised or low-profile antennas may lack performance and efficiency, but are often much quicker and easier to deploy.
In my opinion, field operators should keep both types of antennas in their arsenal because sometimes the site itself will dictate which antenna they use. I’ve activated many sites where wire antennas simply aren’t an option.
That was not the case last Tuesday, however.
Tuttle Educational State Forest (K-4861)
On Tuesday, December 29, 2020, I stopped by Tuttle Educational State Forest (K-4861)–one of my favorite local state parks–for a quick, impromptu activation.
I had no less than four antennas in my car that day and Tuttle is the type of site where I can install pretty much anything: they’ve a spacious picnic area with large tables, tall trees, and parking is close by. Tuttle is the perfect place to deploy not only a large wire antenna, but a large radio if you wish since you don’t have to lug it far from the car.
But en route to Tuttle I decided to take a completely different approach. One of the four antennas I had in the car that day was the Elecraft AX1 antenna.
Without a doubt, the AX1 is the most portable antenna I own. It’s so compact, I can carry it in my pocket if I wish.
When I first purchased the AX1, I was very skeptical and assumed it would only work when “the stars aligned”–days with better-than-average propagation and lots of POTA hunters/chasers looking for me.
The first time I used the AX1 in the field, it impressed me (understatement alert).
In all of my AX1 activations, however, I had only operated on the 40 meter band where the antenna’s footprint looked more like a NVIS antenna than a vertical. Meaning, most of my contacts were in neighboring states like Tennessee, South Carolina, Virginia, and Georgia (typically, those states are in my 40 meter skip zone).
The reason I hadn’t tried 20 or 17 meters with the AX1 is because I would start an activation on the 40 meter band and accumulate enough contacts to achieve a valid activation. Since I’m often pressed for time, I simply didn’t bother configuring the antenna for the higher bands.
Time for that to change!
The question I wanted answered at Tuttle: could the AX1 antenna work “DX” stations? By DX, I mean POTA DX, so distant states and provinces primarily–not necessarily other countries.
I paired the Elecraft KX3 with the AX1 at Tuttle. This was the first time I’d ever tried this particular transceiver/antenna combo.
After setting up, I started on the 20 meter band and called CQ for a few minutes.
The first two stations I worked were in Texas (KF9RX and K5RX).
The third station (W6LEN) was in California.
California!?!
Honestly, it was/is hard for me to fathom how in the world 10 watts into a tabletop telescoping whip antenna could work a station exactly 2,083 miles (3,352 km)–and three time zones away–from my picnic table. I’m sure W6LEN has a great antenna on the other end, but I bet he would be surprised to learn that my 10 watt signal was being radiated by such a wee antenna.
I then worked stations in Florida (K2WO), Minnesota (N0UR), and New Hampshire (W2NR) and decided to move to 17 meters.
On 17 meters I worked W2NR in New Hampshire once again.
I should note here that each time you work a station on a different band or with a different mode, it counts as a separate contact in POTA. In other words, my contacts with W2NR on 20 meters and 17 meters counts as two logged contacts toward my overall QSO count. I’m very appreciative of hunters who go out of their way to work me on different bands and modes: those extra contacts help me achieve a valid activation in short order.
I then moved to 40 meters and worked stations from Tennessee, West Virginia, Ohio, and Michigan.
Video
Here’s a video of the entire activation. It’s a long video as it starts at set-up and continues until my last contact. There are no edits in this video–it’s a real-time, real-life deal and contains all of my bloopers:
Note that in the video I had the KX3’s volume maxed out so that it could be picked up by my iPhone microphone. The KX3’s wee internal speaker was vibrating the chassis ever so slightly. On the 40 meter band, it resonated enough that it moved the encoder slightly. Next time, I’ll plan to bring a portable external speaker (if you have any suggestions of good ones, let me know).
I should also add that I’m very pleased with my new Bioenno 3aH LiFePo 12V battery. You can see it in the photo above–it’s slim, lightweight, and very compact.
I purchased it during Bioenno’s Black Friday sale. I was a little concerned it might not have enough capacity to carry me through multiple activations–my other LiFePo batteries re 4.5 and 15 aH–but that does not seem to be the case at all! Not only did it provide nearly an hour of intense use on this activation, but it also powered three activations the previous day–all four activations on one charge! Brilliant!
Radio magic
As I mentioned in a previous post, this was one of those activations that reminded me of the magic of low-power radio. It was incredibly fun!
For all of those phone/SSB operators out there, I will eventually see how successful I can be doing a phone-only activation with the AX1 antenna. I’ll plan to make a video of it as well. I’ll need to plan this for a day when I have more time to spend on the air and at a site where I know I’ll have internet access to spot myself to the POTA network. SSB isn’t quite as effective as CW when operating with a setup this modest. Still–it can be done! It just requires a little more patience. Please let me know if this sort of thing would interest you.
