#POTAThon1111 – report from the field

by Vince (VE6LK)

My goal is to activate all of the parks I can that have never been activated.

I’m blessed to live in such a beautiful part of the world and see these parks up close. One wall in my shack has a map of all the un-activated parks and routes within a day’s drive of me, and most are already planned with routes. There will be more #POTAThons!

[Click all images to enlarge.]

#POTAThon is what I call it when I plan on getting to more than one park in a day. Usually these things aren’t thought of for weeks in advance, they are more like a “tomorrow morning” kind of thing. Opportunistic, if you will.

But first, a note about the day I chose…

November 11 is called different things in different countries, but what we share in common is we honour our Veterans and we give thanks for the freedoms they fought for. So today I paused to give thanks and think of the lives they gave so that I have the freedoms I do today. I would bundle up that giving of thanks into an urgently needed day away from the office.

And with that, #POTAThon1111 was born.

#POTAThon is what I tag these activities on my Twitter feed and the month and day denote when it happened. By definition a #POTAThon is more than one activation in a day; I’m simple like that. #POTAThon1111 is the third such event.

The first was #POTAThon0930, an ambitious day attempting 8 sites with two operators and most of them in backcountry outside of cellular range. You can see the video from that day when you click on this link. We didn’t get to all 8 but we had a hoot trying.

Just before I departed for #POTAThon0930, Thomas Witherspoon K4SWL (you know him, right?) said words to me I’ll never forget: “Vince, just work CW at a speed where you are comfortable, people will adjust. If you work the sacred language, I will find you.”

With those words of encouragement, I gave it a go. On that day I worked CW and a bit of SSB, but since then it’s been all CW for POTA. While the propagation wasn’t with Thomas and I on 0930, we did connect some weeks later – KX3 to KX3 no less.

You need to understand that I think I’m terrible at CW, but I also need to let you in on a secret: there’s no such thing as a Bad CW Contact. I explain that concept in more detail on YouTube, and the essence is: just do it and roll with it, warts and all. People adjust their ways and usually their speed. Go out and have fun trying.

Field Report: How I evaluate a new POTA site plus serious QRP fun with my new-to-me Elecraft KX1

3 Comments

On Friday, October 7, 2022, I had a couple of errands to run in/around Morganton, NC. Of course, I always have POTA in mind so squeezed in an activation at nearby Tuttle Educational State Forest that morning.  That activation took longer than expected due to swapping out antennas and radios, but it was a success and quite fun.

After Tuttle, I knew I could fit in one more activation if I made it quick, so I set my sights on Table Rock Fish Hatchery (K-8012), but first I had a couple of errands to run in Morganton!

I visited my friend Hamilton at his ceramics studio, popped by another store to pick up a couple of items, then (on Hamilton’s advice) grabbed lunch at the The Grind Café.

I must say that Hamilton was spot-on. My wrap was delicious!

Just what I needed to fuel another POTA activation, right? Right!

After lunch, I drove to Table Rock Fish Hatchery. The weather was ideal and the leaves were beginning to show color.

At our home in the mountains, we were almost at peak leaf color, but the fish hatchery site is much lower in elevation. The weather was simply ideal.

On days like this, driving to a site is half the fun. Continue reading Field Report: How I evaluate a new POTA site plus serious QRP fun with my new-to-me Elecraft KX1 →

QRP POTA Activation During the CQ World Wide Contest

by Joshua (KO4AWH)

I had an opportunity to activate Fort Yargo State Park (K-2177) during the CQ WW DX contest.

Fort Yargo is my local park, about 30 minutes away. The park features a great playground for the kids to play on and many tall trees which are perfect for deploying a wire antenna. There really is not much more I could ask for in a POTA location. Even the noise floor is very low, about S0, so I typically turn on the pre-amp which brings it up to S2-S3 on my Discovery TX-500.

This was very much a last minute plan. I knew the contest was going on which may present some difficulty activating QRP. I knew I would not be calling CQ on 20m where I normally activate and hunting stations could be difficult but likely doable.

There was a bit of rain at the house in the morning, then a promise of drizzle the rest of the day. Not too sure what I would find at the park, but hopefully the rain would hold off and I could get the activation in using the TX-500 without too much worry about it getting wet. I threw in a picnic blanket with a water barrier that promised a bit of protection from the rain if needed it.

I have a go-box setup with my TX-500 and IC-705, as well as several antennas, an ATU, and all cabling and power needed to run FT8 either on my Raspberry PI4 with the TX-500, or on my iPad through the IC-705.

I was taking my wife’s vehicle as she had the car seats needed for the 3 kiddos that were coming along. So, I had to be sure I had everything I needed. There are quite a few additional radio items I keep in the back of my car that I would not have available. But everything should be in the go-box, right?

Go-Box with two full stations, TX-500 and IC-705

After a bit of mist and some rain on the drive over, I planned to setup the TX-500 knowing it would get a bit wet. I tossed the throw line in the tree and pulled up my Tufteln EFHW QRP cut for 20m. In retrospect I probably should have pulled up the EFRW for a bit more band agility.

I tuned around for a few minutes.

Yup, there was not a single free place across 20 meters where I could start calling CQ in the clear. In fact, the stations I listened to for more than a few seconds had someone else start calling right on top of them. 20 meters was indeed crazy.

I could try to hunt some DX with my QRP signal, it would be a fight no doubt, and a nice challenge. After another DX station I tuned to had someone in the States start calling right over top of them, decided not to hunt.

QRP DX: A quick POTA break with the Penntek TR-45L on the Blue Ridge Parkway

12 Comments

As I’ve mentioned in the past, I feel pretty lucky to live in an area that is  flush with POTA sites.  It’s not that we have numerous individual parks, but the parks we do have encompass massive portions of the area.

One park, in particular, that literally runs around and through Asheville, NC, is the Blue Ridge Parkway. When I’m in town and have a few free minutes, it’s quite easy to hit the BRP; it’s never far away.  I can set up along the parkway pretty much anywhere, or go to the Visitor’s Center or Folk Art Center if I want to operate from a picnic table. In addition, the Mountains To Sea Trail runs along large portions of the parkway, so it’s very easy to hit it as well.

On Wednesday, September 28, 2022, I took my daughters to a class and had the better part of an hour to play radio. The BRP’s Folk Art Center was only a 10 minute drive from their class, so I made a beeline for the site as soon as I dropped them off.

I had the amazing Penntek TR-45L packed in my car, and decided to pair it with my Tufteln End-Fed Random Wire antenna.

Jay discovered that his first CW POTA activation wasn’t scary at all!

20 Comments

Many thanks to Jay (W1ASP) who, last week, sent me a note about his first POTA CW activation. I asked if he’d consider writing up a short field report about his experience to share with others and he was happy to do so. Thank you, Jay.

Halloween POTA

by Jay (W1ASP)

Halloween doesn’t have to be scary.

I set out to Bear Brook State Park (K-2643) for my first CW POTA activation.

Bear Brook is relatively close by, its the largest state park in New Hampshire with over 10,000 acres. There’s camping, hiking and biking trails along with an archery course and plenty of swimming and fishing areas.

I didn’t give it much thought about what day it was, just that I had the time to do an activation and it was nice out, what a perfect opportunity to break in the newly assembled kit.

I decided on a spot next to the water and as luck would have it there was a picnic table right there. I took out my gear, set up and proceeded to tune around and listen. The band seemed pretty quiet. I wasn’t sure if I’d get enough QSO’s in to make it an official activation. I decided on 14.038 MHz, I sent QRL? I then held down the memory button, took a deep breath and hit it again to transmit: CQ POTA DE W1ASP

I waited a second or two and used the memory keyer once more, again nothing. I went to the POTA website on my phone and added my activation.

The memory keyer was used for a third time, I noticed a message pop up on my logging app, the Reverse Beacon Network spotted me. It wasn’t too long after, the first call came back to me!

I was nervous and fumbled a bit here and there but once I took my time I was fine, sending their call back and TU UR 599 599 NH BK. I cheated a little and left the CW decoder enabled. I wanted to be sure I had the call correct as I logged my 13 QSO’s. (I swear the 13 wasn’t intentional.) for my first CW park activation! I only realized that it was Halloween while walking back to my truck.

I thought to myself, “that wasn’t scary at all.”

Once I decided that, as an activator I’m in charge of the QSO, I relaxed and it was a lot of fun. I may have made a few mistakes but everyone was patient with me. I later received an email from another Ham in Delaware. He was using the same radio, and referred to them as the perfect “picnic portable radio” we emailed back and forth a few times and I look forward to hearing him on the air again soon.

 

The week before, I finished building my second QCX Mini. The first kit I built was for the 30 meter band around this time last year, this second one is a 20 meter version. I love these little radios, there’s something about these little transceivers that I just can’t seem to put them down.

I took my time making sure it was working properly, I hooked it up in my shack and I had my first QSO with another POTO activator in Maryland just over 400 miles away.  To say I was excited is an understatement!

I planned on putting together a kit about a month ago for POTA and eventually SOTA with the QCX Mini as the radio. I decided on using a small pack, I wanted it to be a self contained kit that had everything I needed to do an activation and nothing extra.

I keep the wire and radios together,  and depending what band I choose to operate on is the one I pack. I’m considering a third kit; maybe a 10m version? I threw the EFHW matching transformer in the bag along with a notebook, mechanical pencil and a battery pack I put together using four 3.2v LifePo batteries. The paddle I’m currently using is a stainless paddle I found on online with a mini CW paddle for backup and set of folding headphones.

I’m looking forward to my next park, this was a great experience. I wanted to learn CW since I became a Ham in 2016, that’s another story of what got me into Ham Radio in the first place.

POTA Plan C: Swapping antennas and rigs at Tuttle Educational State Forest

9 Comments

After the success of my previous day’s activation at Fort Dobbs State Historic Site, I decided to take the Icom IC-703 Plus out for yet another activation.

As I mentioned in the previous post, the IC-703 has not gotten a lot of outdoor time this year because I’ve had issues with the electronic keyer locking up when using the radio with end-fed antennas.

Of course, there are a number of ways to mitigate or radiate the RF that could be coming back to the radio, so at Fort Dobbs, the previous day, I used a simple common mode choke. It seemed to do the trick.

I was curious if using a common mode choke might be the only solution needed to solve this problem, or if I’d need to perform a mod to my IC-703.

I was ready to test the IC-703 again.

I had a fair amount of antenna options in the trunk of my car, so on the way to Tuttle Educational State Forest (on Friday, October 7, 2022), I considered a few options to shake things up a bit.

Since I was feeling comfortable that the common mode choke was taking care of things, I decided to push the limit a bit and deploy an end-fed random wire antenna. I didn’t have any of my mini portable 9:1 random wire antennas in the car (PackTenna, Tufteln, etc.), but I did have another solution: the Chameleon MPAS Lite.

The cool thing about the CHA MPAS Lite is that while it’s primarily designed to be a vertical antenna with counterpoise, it can be reconfigured and deployed a number of ways including as a simple end-fed random wire antenna.

After giving it some thought, I decided it might be fun to deploy it as an inverted V random wire. In fact, here’s a diagram from the MPAS Lite manual of exactly what I planned to do.

I’d be using the MPAS Lite counterpoise as the radiator, so I wouldn’t have the optional second counterpoise as seen in the illustration above. That’s okay, though, because I was feeding the antenna with Chameleon’s 50′ RG-58C/U cable with in-line choke; the shield of the coax would act as the antenna counterpoise.

This is the same coax cable I used the previous day. Continue reading POTA Plan C: Swapping antennas and rigs at Tuttle Educational State Forest →

Rich’s Triple Activation Day!

Many thanks to Rich (KQ9L) for sharing the following field report:

Triple Activation Day

by Rich (KQ9L)

I decided to build on the momentum and lessons learned from my last two POTA outings and yesterday [October 29, 2022] completed x3 Activations in one day— a first for me. I wrote a brief description of the day and I hope you enjoy reading about the activations.

Well the weather has been pretty good here in Chicago and Old Man Winter hasn’t made it around to these parts yet and being on a POTA kick lately, I decided see if I could complete several activations in one day. Previously I had completed x2 in one day, but felt that after all that I learned from my last couple activations, I should practice what I learned and go for three.

In my area, there are several POTA sites, but one area to the south of me seemed to be the best location to accomplish my goal. The area has a unique geographic feature and historically interesting landmark which added to the lure of the area. The region centers around the Illinois and Michigan Canal.

Here is a quick history lesson courtesy of Wikipedia:

The Illinois and Michigan canal was build in 1848 and served as a connection between the Great Lakes and the Mississippi River. Running 96 miles, it connects Bridgeport in Chicago to LaSalle-Peru. Why was this important? This connect helped establish Chicago as the transportation hub of the US and linked by water the East coast to the Mississippi River and from there the Gulf of Mexico. Before the railroad era in the US, this water way dominated transportation.

Pretty cool!

Along the canal are numerous little hamlets and one in particular, Morris, Illinois had x3 State Parks all within about a 5 mile radius. Perfect!

First stop was Gebhard Woods State Part (K-0995). The park is only 30 acres, but affords activities for hikers, fisherman, campers and picnickers. There is even an eBike rental facility so the park has broad appeal to many people, including hams!

I arrived pretty much right after sunrise and was greeted by fog and a thin layer of frost on the grass and picnic tables. Though beautiful this frost and fog, did not make for a fun activation. Temps were in the upper 30’s F, but with the fog the air felt damp and overall much cooler.

I hurriedly set up my PackTenna 9:1 antenna on my collapsible mast and leaned it up against a nearby tree. I had a separate counterpoise and feed line with a choke built into it…more on this later.

Breaking 100 QSOs during two QRP SSB Activations

by Joshua (KO4AWH)

Back in May I had to travel last minute for work to North Dakota. I typically bring radio gear in the event that I have some time to do a Parks On the Air activation. This trip presented the opportunity to activate a park in Minnesota as well as one in South Dakota. I didn’t have much time to plan these activations, but I knew I had an early enough arrival in the afternoon that I could likely activate a park in MN and then in SD. So, I picked out a park in MN close to my destination. I could go activate in MN then get over to a park in SD and activate there.

I found a nice looking State Park in MN. The idea was to activate as quickly as I could and then get back to a park in ND with enough time to activate before it got too late. K-2482 Fort Snelling State Park had 110 successful activations. That is always promising when planning out an activation. I got my rental car and headed to the park.

I also had recently purchased a HFJ-350m which is a base-loaded coil with an extendable whip. I found a tripod base I could print online and then designed an adapter so I could install a SO-239 and RG316 lead with a BNC connector. I had just tested this setup in the back yard and knew it worked, although I certainly knew it was a compromised antenna.

I typically bring my Raspberry PI4 loaded with Build-A-Pi and then run digital modes from my phone or Tablet. My plan was to activate this park with the compromised antenna running 5W on FT8 at the first park and then go to my second park and run a full half wave wire in a tree on SSB at 10W.

Not much to say about the activation in MN. The state park was nice but where I set up presented quite a bit of RF noise. Not so much of a problem since I was running digital. After a bit of adjustment on the whip I was tuned for 20m and started hunting a few FT8 stations. I did make a few QSOs while hunting but I then started calling CQ and had a bit more luck. I think because my signal was quite weak, calling CQ was a bit more efficient as only those who could hear me were calling back. While hunting, if those calling CQ were running a bit more power, I was unlikely to get in while running lower power and on a compromised antenna. I got the activation completed with 12 QSOs and packed it up and headed to the next park.

POTA with the Icom IC-703 Plus: Working a serious SWR problem first, though!

26 Comments

If you’ve been here long, you’ve no doubt noticed that I have a sizable collection of QRP radios I take to the field.

Although I have some favorites, I try to rotate all of my radios in the field and even pair them with different antenna combinations as much as possible. If I only owned one field radio, I’d shake things up by pairing my one radio with different antennas deployed different ways during my POTA/SOTA activations.

I get a real thrill out of testing different combinations, actually, and I feel like it keeps me on my toes because I don’t get too comfortable with any one setup in the field.

No doubt, using a wide variety of radios gives me a more informed perspective when beta testing or evaluating new radio models.

That said, there is one radio in my collection that has been overlooked too many times: my Icom IC-703 Plus.

Many of you have noticed this, in fact.  I’ve gotten several emails and comments asking, “So Thomas…when are you taking the 703 out again–?” 🙂

When I purchased the ‘703 from my buddy Don a couple years ago, I imagined taking it to the field very regularly. I always thought it was a cool little radio and with its built-in ATU, it’s quite compact for a tabletop-style rig.

Thing is, each time I’ve taken it to the field, I’ve had issues with the electronic keying that I did not have when using it in the shack. It’s quite sensitive to RF, so end-fed antennas seem to create unwanted dits and dashes in the keyer.

The simple fix, I hoped, was simply using an in-line common mode choke to keep the RF away from the radio. Thing is, the IC-703 has an SO-239 antenna port and two of my common mode chokes are BNC. I meant to purchase a BNC-to-PL-259 adapter at the Shelby Hamfest, but picked up the wrong item (I should have been wearing my glasses).

Then I remembered that my Chameleon 50′ RG-58C/U cable not only has an integrated in-line choke, but also PL-259 connectors. This could work! Continue reading POTA with the Icom IC-703 Plus: Working a serious SWR problem first, though! →

Mark’s first POTA activation with the Penntek TR-45L

Many thanks to Mark (W8EWH) who shares the following field report:

An Afternoon POTA Activation with the PENNTEK TL-45L

by Mark (W8EWH)

I have a hard time resisting new QRP radios, and I have an equally hard time resisting getting outdoors when late October brings 70F (21C) temps to Michigan.  Days like these are especially sweet given we saw the first snow here last week (no accumulation – but still…). For me there was no better way to enjoy this unexpected weather gift than with an early afternoon POTA activation with my newest QRP radio, the PENNTEK TL-45L.

The TL-45L is the latest radio from WA3RNC, joining the TR-35 and TR-25 in his online store.  It’s a 5-band, 5-watt CW transceiver covering the 80, 40-, 30-, 20- and 17-meter bands.  That in and of itself is not particularly noteworthy.  But when you look at this radio, you’ll immediately see what makes it different.

The retro look for me is unlike anything I have seen in a modern QRP radio.  It frankly looks like it was removed from an Apollo Command Module.  From the front meter to every knob and switch, this radio just begs to be fiddled with.  And each knob and switch serve a function that means no longer needing to dig through menu after menu to find where the narrow filter is switched in because of nearby QRM, or so I can slow down when my CQ POTA is responded to by a slower CW call.

The speaker is located on the (left) side of the radio, a feature many smaller QRP radios don’t have, though headphones can be used via a front mounted jack.  The radio sounds great – I think the radio’s case provides a nice sound chamber.

The TR-45L comes with a couple of options, neither of which I chose to add to my order.  One is a built-in rechargeable battery (5200 mAh), and the other an antenna tuner.  I have plenty of batteries, and normally use resonant antennas.

With the Monday late morning temperature approaching 70 I packed the car with radio gear, and my wife, and we headed out to Island Lake State Recreation Area (POTA K-3315) to activate this park with the TR-45L for the first time.  My wife is not a ham but often comes with me to POTA activations.  While I set up, activate, and then pack up, she enjoys the outdoors with a magazine and crossword puzzle, and sometimes, like today, a light lunch.  Usually, once the activation is complete, we’ll go for a hike on park trails.

Island Lake is about a 20-minute drive from my house.  Its 4000 acres is a mix of open fields and hardwood forests surrounding Kent Lake and the Huron River.  Today it was warm enough that someone was using a paddle board on the lake.

I have found a set of picnic shelters on elevated ground overlooking Kent Lake as a great place from which to activate.  I worked North Pole Alaska from this location on 20M CW using my IC-705 with 10W into an EFHW last May.

Once at the shelter I set up my EFHW (KM4ACK kit) in a sloped configuration using a conveniently located mature tree and my throw line.  It was roughly in an East/West orientation. Over the preceding weekend, I added PowerPole connectors to the provided power cord, and programed both internal CW keyer memory slots.  These are activated using either dit or dah paddle when I toggle Play using the provided switch.   Of course, I did a little POTA hunting using the home antenna to familiarize myself with the TR-45L’s operation.  The learning curve is short with nothing hidden deep behind any menus.

With the radio and antenna ready to go, I set up HAMRS on my iPad, spotted myself on the POTA website, and started calling CQ POTA on 14.0615.  Over the course of the next 35 minutes, I worked a total of 30 stations on 20M and 40M (most on 20M) at which point I basically ran out of hunters.  Not bad for a weekday afternoon.  I packed up and went on a couple mile hike with my wife.

The TR-45L is an absolute joy to use.

I forgot to put it in CW Narrow mode at first, and when nearby QRM popped up, I was able to add this in with the throw if one switch. QRM gone.  (Note, this setting – wide vs. narrow filtering – must not be retained after the power is shut off or the battery is disconnected.)

It sounds wonderful.  I used the side speaker the whole time as my wife doesn’t seem to mind, although the random guy who wandered in with a laptop to get some work done on a warm fall day decided to find somewhere else to work.  There are front mounted jacks for headphones, paddles and a straight key.  Even a rear mounted jack for an external speaker.  The built-in speaker can be turned off and on via a toggle switch.  The two CW memory slots are easy to fill using your paddle.  The front meter can show power output or SWR based on toggle switch position, and you are alerted to high SWR via a front mounted red LED.

I waited a while to get this radio.  Recent supply chain issues caused unexpected delays, but it’s available for order now in factory-built form and most definitely worth the wait.  Kits will eventually be available.  Check out all the TR-45L details here.
