Activating Independence National Historical Park, Philadelphia, Pennsylvania

August 21, 2024

By: Conrad Trautmann, N2YCH

I recently took an overnight trip from Connecticut to Philadelphia via Amtrak and before I left, I checked to see what parks in Philly I might be able to activate. Conveniently, Independence National Historical Park (US-0738) was a short 15 minute walk from the hotel. So, along with a change of clothes and my toothbrush, my Elecraft KX2 transceiver and AX1 antenna went into the backpack. This is my preferred equipment when I need to travel light.

Equipment List

Independence National Historical Park is actually a series of attractions that are managed and run by the National Park Service, including Independence Hall, the Liberty Bell Center, The Benjamin Franklin Museum and Washington Square. Looking at the map of the location I decided to use a bench in Washington Square to activate from. The yellow highlight in the map below is where I set up.

I was able to set my AX1 up using the tripod on the grass behind the bench, keeping the RF wire and counterpoise out of the path of traffic.

I got all set up, spotted myself on the POTA page and pressed “Enable TX” on WSJT-X and the radio would not transmit. I checked everything…the CIV cable, the audio cables, the settings in WSJT-X, the windows audio settings, the com port…and I still couldn’t transmit. It was decoding fine.

I went to the Elecraft KX groups.io and searched, I searched Google and tried things people suggested and still, no transmit. I changed the CIV cable and the audio cables and interface, since I had spares and even that didn’t work. Thirty minutes later, ready to give up, I tried turning the KX2 off and then back on again and yes, you guessed it, a reboot solved the problem. I’ll try that first next time. I’ve never had that happen before, but you live and learn.

So, I re-spotted myself, got on the air and knocked out 10 contacts pretty fast once I could transmit. I made two additional QSO’s for good measure for a total of 12. Here’s my coverage map…I was running FT8 on 20 meters and I was surprised to make it to Florida to get Matthew, N4MRD. Clint, W9AV also hunted me…that should be a familiar call sign to many activators.

Once I was done and packed up, I took some extra time and checked off a bucket list item. I walked another block North past Independence Hall and visited the Liberty Bell Center to see the historic bell in person. Admission to see the Liberty Bell is free.

If you ever head to Philadelphia, this is an easy city site to activate so I recommend bringing your radio to activate the park.

QRPppppp….WSPR

By: Conrad Trautmann (N2YCH)

WSPR, or Weak Signal Propagation Reporter, is a digital mode you can select within WSJT-X. You can use the data that’s generated by the WSPR network to check your own antenna’s performance for transmitting and receiving and also to see what paths are open by band at a particular time of day from your QTH. Recently, I’ve been using WSPR to improve my own antenna systems and to help reduce local noise sources.

Originally developed by Joe Taylor, K1JT, an approximately two minute QRP transmission contains the originating station’s call sign, the maidenhead grid locator and the transmit power level being used. Stations typically use 250mw up to 5watts when they send these signals. WSJT-X allows you to select how often you want to send this transmission and what bands to transmit on. There’s an embedded schedule in WSJT-X that allows “band-hopping” for stations using a multiband antenna to transmit on different bands. When not transmitting, it listens for and decodes other stations transmitting and can post “spots” of those stations to the WSPR network database.

WSJT-X WSPR mode

WSPR Band Hopping Schedule (click to enlarge)

Here on QRPer.com, Thomas, K4SWL posted in this field report what the various flavors of QRP power levels are…

  • QRP: 5 watts to 1 watt (for some contest 10 watts = SSB QRP)
  • QRPp: Less than 1 watt to 100 mw
  • QRPpp: Less than 100mw

Did you know that there are more than 3,000 WSPR HF beacons running on all of the amateur bands all over the world at QRP power or less? Many are running 250mw or less. If you open up WSJT-X and select the WSPR mode, you’ll see that the pull down for power levels give you these options:

  • 37dbm = 5w
  • 33dbm = 2w
  • 30dbm = 1w
  • 27dbm = 500mw
  • 23dbm = 200mw
  • 20dbm = 100mw
  • 17dbm = 50mw
  • 13dbm = 20mw
  • 10dbm = 10mw
  • 7dbm = 5mw
  • 3dbm = 2mw
  • 0dbm = 1mw

You could transmit your own beacon if you choose to using WSJT-X. You can also receive many of the 3,000+ beacons that are on the air right now if you wanted.

Why, you ask?

Let me tell you about the WSPR journey I’ve taken over the past few months and how what I’ve learned has benefitted me, my station and my antennas. Here’s how extreme QRPpp signals can help all of us.

I’m an avid digital operator, and I’ve tested many of the digital modes that WSJT-X, FLDigi, VarAC and others have to offer.

WSPR (Weak Signal Propagation Reporter) is a program embedded as a mode in WSJT-X and you can set it to transmit at the various power levels I listed above and band hop to different bands if your antenna can support those frequencies. When it’s not transmitting, it will receive and post the beacons it hears to the WSPRnet.org web site. For anyone familiar with pskreporter.info, WSPRnet.org is similar in that it provides maps of where and when “spots” are received and the relative signal strength the signals were when received by station, the mode and frequency.

After setting my station to transmit and receive on WSPR and looking at my spots on WSPRnet.org that were reported by receiving stations over the previous day, it was a thrill to see my 250mw signal making it out all over the world. Amazing actually, that such a small amount of power could travel that far. 250mw to Antarctica? That’s pretty good.

I bought a QRP-Labs QCX transceiver and the external companion GPS clock, which supports running WSPR transmission stand alone, without tying up a computer. Then I learned about the Sotabeams WSPRLite Antenna Tester (a 250mw WSPR transmitter) and the various WSPR transmitters offered by ZachTek which can also run without needing a computer.

My goal was to have WSPR beacons transmitting on as many bands as possible. Combining them into a single, multiband antenna posed its own problems, which is a topic for another article. However, all of these solutions just transmitted. I was hoping to also be able to receive and post spots as well.

Then, QRP-Labs (shout out to Hans Summers) came out with the QDX and then the QMX, both of which connect to a PC and are controlled by WSJT-X to do the band hopping transmitting and receiving. Like FT8, WSPR does depend on timing to work best, so using an external GPS clock for the QCX or connecting a QDX or QMX to a computer that can get it’s time from the internet can help keep the transmission cycles in sync with the receiver sites for best reception results.

Various WSPR transmitters and transceivers

This is cool stuff, but still, what’s the point? That’s when a friend I made in the WSPR community, Tom, WA2TP pointed out how to use all of these beacons to improve my station’s receiving capabilities. I have a good HF receiver and a dipole antenna and a hexbeam on a rotor and I figured I was good to go. I was making contacts without any problems. Tom told me this: “It’s all about the noise.”

He recommended using a wideband SDR called a Kiwi that can view the entire HF spectrum from 0 -30MHz on a waterfall at one time. My ICOM IC-7610 can connect to a PC and work with HDSDR software which has a waterfall, but it will only show you the spectrum of the particular band you’re on, not the entire HF spectrum at once. The Kiwi shows the entire spectrum from 0 to 30 MHz and when set up just right, you can see noise in there…a lot of noise, emanating from all sorts of things.

If you’re trying to receive a 250mw WSPR beacon signal transmitting from Australia, the noise from the after-market, wall-wart switching power supply connected to your cell phone charger a few feet away from your antenna could be way noisier and will blank that VK beacon right out. Your antenna and ability to hear distant signals is only as good as how low or quiet the local QRM is that we all have to deal with.

So began my hunt for noise, with a lot of guidance from folks with experience at it. Continue reading Beyond the Beacon: Conrad Discovers the Unexpected Benefits of WSPR →

QRP POTA & SOTA on Killington Peak, Vermont

By Conrad Trautmann (N2YCH)

Peter (K1PCN) and I decided to travel from Connecticut to Vermont to view the solar eclipse that occurred on April 8, 2024.

We got an early start on Sunday morning April 7th to drive to Rutland, Vermont where we stayed overnight. This positioned us well for a short drive the next morning to drive North towards Burlington, where we’d be under the path of totality.

Knowing we’d have some extra time on our hands on Sunday afternoon, Peter planned two park activations. Our first stop was Calvin Coolidge State Park (POTA US-5541 & SOTA W1/GM-002), which encompasses Killington Peak and is also a two-fer with the Appalachian Trail (US-4556). We also activated Gifford Woods State Park (US-3115), which isn’t too far from Killington.

For the trip up the mountain, we “walked-on” the K1 Gondola ski lift to get up most of the way.

From the top of the ski lift, we hiked another 360 feet, up 100 feet in elevation, in the snow, to get to the actual summit at approximately 4,230’ above sea level.

Photo of Peter and me on the summit

Our kits needed to be self-contained and not too heavy for the hike. Peter packed his Icom IC-705 along with a fiberglass mast and an end-fed half wave wire antenna to do a sideband activation. I brought my Elecraft KX-3, 3Ah Bioenno LifPo battery, and the Elecraft AX-1 antenna to do a digital activation. We both activated on 20 meters and were far enough apart that we didn’t interfere with one another. We also tried 17 meters.

Peter, K1PCN’s Equipment List

After the hike up, we surveyed the area to see where the best spots would be for us to set up. Peter took one side of the summit while I set up on an exposed rock so I wouldn’t be sitting in the snow. Peter wore his ski pants…I, on the other hand, ended up with wet jeans by the end. I’ll re-think my attire the next time I do this. I got the radio equipment right but not the clothing selection. Priorities!

In addition to the HF radios, we both brought our VHF/UHF handhelds to make contact with each other as well as anyone who might be nearby. Peter brought a Baofeng UV-5R and I brought a Kenwood TH-D72. I was lucky enough to complete a QSO with someone who was mobile and driving along US Route 89, which at its closest point to Killington Peak is a solid 20 miles away. I verified that via email with the other ham after the fact. Continue reading SOTA, POTA, and a Total Solar Eclipse Adventure: Conrad and Peter Pack It In! →

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

FT8CN Field Report

By: Conrad Trautmann (N2YCH)

February 24, 2024

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

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

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

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

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

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

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

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

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

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

Equipment List

Extra Items I brought for the test

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

AntScope shows a decent match at FT8 frequency.

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

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

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

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

Washington, DC Field Report

By: Conrad Trautmann, N2YCH

January 30, 2024

Periodically, I travel to Washington, DC for my job. On my latest trip, I carved out some time to activate some parks. The hotel I was staying at is just a few minutes away from the National Mall, which provides many activation options on the POTA website. After scoping it out on Google Earth and researching trails using the National Parks mobile app and web sites, I settled on the Jefferson Memorial, K-0792 as my first stop which is a two-fer with the National Mall, K-0655.

Just steps away is the George Mason Memorial where the Potomac Heritage Trail National Scenic Trail, K-4564 passes right through and is located along the East bank of the Lower Potomac River. The Captain John Smith Chesapeake National Historic Trail, K-4567 runs by as well. The bench I found on the shore of the river met the minimum 100’ rule for both trails and was also located in the National Mall park, so this location was a three-fer.

I tried to travel as light as possible this trip. The gear I chose to bring was the Elecraft KX2 along with the AX1 antenna and my laptop with the USB sound card and CIV cable.

The January winter weather was mild, in the low 40’s F so setting up and activating outside wasn’t a problem. With it being off season for tourists, I had the park almost all to myself.  There were signs posted at the memorial asking visitors to be quiet and respectful, so the last thing I wanted to do was set up on the steps and draw attention to myself. I found a wall near the Tidal Basin’s water’s edge and was able to set up out of the way of anyone wanting to photograph the memorial, but still be on the property.

N2YCH: January POTA Travel in Frozen Alaska!

Conrad’s January Alaska Activation

By: Conrad Trautmann, N2YCH

“Why would you go to Alaska in January?” is what everyone asked me.

I’ve wanted to see the Northern Lights for as long as I can remember. The best time to see the aurora borealis is between late August to late April in Fairbanks, Alaska. Days are short in January, sunrise is at 10:24am local time and sunset is at 3:38pm. It’s twilight before the sun comes up and after it sets so it’s not pitch dark, but it’s mostly dark for about 19 hours a day in Fairbanks at this time of year. Once I began researching, I learned that peak viewing times for the aurora are between 10p and 2a local time even with the extended darkness. Check aurorasaurus.org for more information.

So, the answer to the question is, “The odds are better to catch the Northern Lights in the winter.”

Cold weather and snow doesn’t bother me having lived in Syracuse, New York for ten years. I have experience with winter weather and driving. Fairbanks is one of the best places in the state to see the aurora since it is directly below the “Aurora Oval” and it has over 100 days a year when the aurora is visible. Except for January 12th through the 15th, 2024, when the sky had 98% cloud cover and it was snowing. Aurora viewing was not happening during my visit.

However, this trip was not a total loss by any means. There are things to see and do here, including activating parks! I activated three parks in three days, Denali National Park (K-0022), Chena River State Recreation Area (K-7228) and Creamer’s Field Wildlife Refuge (K-9697). I’ve heard stories from hams in Alaska that propagation can be spotty, that there can be total radio blackouts from solar flares and that bands we don’t usually worry about in the lower 48, like 20 meters, can be useless at times. I packed enough equipment and antennas to activate on any band from 40 meters to 6 meters, up to 100 watts using my Elecraft KX3 with the Elecraft KXPA100 amplifier. On the first day at Denali, I used the amp for the entire activation, but I realized at the end of the day that Thomas, K4SWL, who runs “QRPer.com” wouldn’t be too happy with a field report from “QROer.com” Conrad, N2YCH. To remedy that, I activated my second park using just my KX3, no amp. At K-7228, my first 11 QSO’s were QRP and the park was officially activated using only QRP power. I activated my third park QRO, read on and I’ll explain why.

[Thomas here: For the record, readers, I gave Conrad a Special Use Permit to mention QRO on QRPer! Ha ha! Of course there’s no problem going QRO from time to time!]

Back to propagation, I emailed one of the most active POTA activators in the area prior to my trip to get a sense of what to expect. I highly recommend doing this for anyone planning to travel somewhere and activate. Look at the POTA pages for the parks you want to activate and you’ll surely see a repeat activator with a Kilo award or many visits to those parks. They know the parks the best and also what to expect for propagation. They also share your passion for POTA and are usually very happy to help. The advice I received was that it would be difficult to make contacts on 20 meters and that watching the MUF (maximum usable frequency) charts would serve me well. (Check out hf.dxview.org) The activator said 10 meters would probably be the best band during daylight hours. He was exactly right. Even with QRO power, 20 meter reception in Alaska was noisy and my signal did not get out very far on FT8 watching the pskreporter.com spot map. I moved to 10 meters and quickly had a steady pile up. I stayed on the air until I depleted a 9ah and a 3ah battery I brought. What fun!

Okay, so for the QRP activation, I was at a trailhead parking area out near the Chena Hot Springs resort. Before the activation, I stopped and did the tour of the Aurora Ice Museum and took a dip in the natural hot springs. I do recommend the hot springs if you ever go to Fairbanks. It was -10F degrees when I was there, quite an experience.

Chena Hot Springs

I intentionally wanted to delay my activation from early morning to closer to sunset to see if operating during the evening gray line passing over would help improve the number of contacts I could get. The short answer is that it was worse…way worse. I went back to activating closer to sunrise on my third day and had similar results as I did the first day, much better. Sunrise wins.

The map above shows my initial ten QRP QSO’s from K-7228.

What really continues to amaze me is just how far my signal can reach with the portable equipment I was using. I brought the Buddipole so I could configure it as a vertical or a dipole. I tried it as a vertical on 20 meters on my first day and as I said, the reception was poor. The beauty of the Buddipole is that I could quickly reconfigure it to a 10 meter dipole. With the tripod, it’s roughly 10’ off the ground. There was no wind to speak of, so I didn’t need to guy it. If there was, I would have used a bungee cord to secure it to the car bumper or side mirror.

It breaks down and fits in the bag I bought with the Buddipole tripod and I tossed it into my checked bag on the plane. With the tripod and mast, it’s just a little too long for the carry-on bag. I could have brought a fiberglass push up mast and wire antennas in my carry-on, but I decided on the checked bag and brought the Buddipole to have as many options as possible. After all, I was traveling all the way to Alaska. Continue reading N2YCH: January POTA Travel in Frozen Alaska! →

Connecticut POTA/SOTA combined activation

By: Conrad Trautmann, N2YCH

November 24, 2023

The author, Conrad, N2YCH at POTA K-1717, Sleeping Giant State Park & SOTA Mt. Carmel, W1/HH-002

Looking for my next activation challenge, I wondered if there were any overlapping POTA parks with SOTA summits in the state of Connecticut. I’ve only done two SOTA activations to date, one in Maine and the other in New Hampshire. I thought, there must be a few in Connecticut.

On my home computer, I brought up both the POTA map and the SOTA mapping page and quickly realized that it would take too much time to try and compare the two maps. Instead, both sites offer KML exports, so I exported all of the Connecticut parks from the POTA site and the summits from the SOTA mapping page and imported both files into Google Earth Pro. A yellow push pin represented the POTA locations and a blue triangle the SOTA locations. It was easy to spot the overlapping sites. Mt. Carmel and Talcott Mountain are both POTA parks and Summits for SOTA. There are a few other SOTA sites that have POTA trails that cross over as well.

I decided to tackle Mt. Carmel, SOTA W1/HH-002 also POTA K-1717, Sleeping Giant State Park. I’d already activated Sleeping Giant for POTA before, but not from the summit. For a SOTA activation to count, the operator must be within the “Activation Zone” as defined by the SOTA rules.

The Connecticut state web site has good maps and information about the park and showed that the trail to get to the summit is an “easy” 1.6 mile hike. I thought that sounded like a reasonable distance. What they don’t tell you on the web site that it’s also a 600’ climb up in elevation from the trailhead to the summit. I knew it would require a climb, but I didn’t expect that. I made the trip up, but it was challenging, especially carrying my backpack with the radio, a VHF handheld, antenna, batteries, computer, water, etc. I plan to travel lighter the next time.

The Mt. Carmel trailhead

Before I get to the activation, a little about the park. It’s called Sleeping Giant because from a distance, the ridge looks like a person laying on their back.

From the CT DEEP site

It’s located in a mountain range called Hanging Hills which extends North from Long Island Sound through Connecticut and Massachusetts up to the Vermont border. Quinnipiac University is across from the entrance to the park and the Quinnipiac Indian Tribe once inhabited the area. Please indulge me as I also share the ghost story of “The Legend of the Black Dog of the Hanging Hills.”

“If a man shall meet the Black Dog once it shall be for joy; and if twice, it shall be for sorrow; and the third time he shall die.”

As the legend has it, the Hanging Hills area is haunted by the Black Dog. You don’t want him to cross your path three times. It’s this story that is the basis for the SOTA “Master of the Black Dog” certificate. “An activator must have entered valid activation logs from each and every summit in the Hanging Hills Region and must have survived all of the activations.” There are currently four summits in the Hanging Hills Region. I need this award.

So far, I have completed activating one of the four summits and did NOT see the black dog. Wish me luck on the remaining three.

The view about half way up

The Lookout Tower

The lookout tower at the summit is the main attraction of the park. Built in 1936, it is listed on the National Register of Historic Places. It stands four stories tall and is 739’ above sea level, providing a 360 degree view in all directions and a clear view over New Haven to Long Island sound. According to the Sleeping Giant Park Association, over 100,000 people visit it each year.

I’ll admit, after hiking the trail up, the last thing I wanted to do was climb four stories more. I did go up before I left to get some photos.

For the activation, I found a bench to set up on with space behind me to set up the Chelegance MC-750 antenna. I ran FT8 on 20 meters beginning around 10 am ET and after roughly 30 minutes, moved up to 10 meters. My experience running QRP on digital modes is that I will cover the Eastern half of the US and some Europe on 20 meters. I can usually make contacts out to the West Coast and into Europe on 10 meters especially later in the day. By activating on both frequencies, I tried to cover as much area as I could to provide the best opportunity for hunters and chasers to reach me.

Setup: MC-750 vertical antenna in grass behind bench and KX3 and computer on bench

Equipment List

Coverage from the summit: Yellow pins are 20 meters, Green pins are 10 meters

Looking at the map, you can see that I covered the Eastern portion of the US on 20 meters. It was also 10 am local time and still pretty early on the West coast. When I shortened up the antenna and retuned the KX3 for 10 meters, I started making contacts with Germany, Italy and other EU stations.

The hike down from the summit was much easier, the temperature had warmed up a bit and I stuffed my coat into the backpack for the trip down. When I got to my Jeep, I noticed a number of empty picnic tables nearby and decided to set up and get a few more POTA contacts while I was there. I ended up with 48 total for the day.

The summit I was at was an easy one (worth 1 point) compared to many and it was challenging to me. I came away from the experience with a new appreciation for the challenges SOTA activators face. I also came away with a new goal, to get the Master of the Black Dog certificate!

Top Band POTA Activation Field Report

In February 2023, Brian, K3ES, wrote here on QRPer.com about designing and building his own QRP portable random wire antenna he called the VK160 to work on 160 meters to make parks on the air contacts. This was in order to achieve his goal of getting the James F. LaPorta N1CC award where activating on 10 bands at 10 parks is needed. It’s not as easy as it sounds. As an avid parks on the air activator myself wanting to try activating on 160 meters, I built my own antenna based on Brian’s design and used it to get my first contacts ever at a park on the “Top Band.”

The Antenna

Brian used a 9:1 unun that he built himself in his design. Rather than build my own from scratch, I took a short cut and bought a QRPGuys 40m-10m UnUnTenna to use as the starting point for my VK160. Even though it says 40m-10m, it works on 160 meters, as you’ll see.

With shipping, it cost $36.00. It comes with all of the parts you need to assemble the antenna except for the wire. The main thing I liked about the QRPguys design was that the circuit board also doubles as a wire winder, so it’s all self-contained.

I sourced the wire from Davis RF and ordered 200’ of “POLY STEALTH – 26 AWG, 19 0.22000 44.00 STRAND COPPER CLAD STEEL, BLACK PE JACKET.” It cost $50 including shipping. The polyethylene insulation prevents the wire from knotting up. I measured out 144’ for the radiator based on Brian’s design and used the remaining wire as the counterpoise.

The completed antenna

I did a back yard test once it was all assembled and it worked great. For $86, I had created my own VK160. I encourage you to read Brian’s detailed design/build report here.

The POTA Activation – November 14, 2023

Now that I had completed building and testing the antenna, the next challenge was how to actually put it to use at a park. 160 meters doesn’t really come to life until dusk or after dark. In Connecticut, most state parks close at dusk. The park rangers clear the parks to close them at the best time to activate the band. However, there is one park nearby my QTH, the Stuart B. McKinney National Wildlife Refuge, K-0228, that has an annex called the Great Meadows Unit in Stratford with a nice parking lot that is not gated and has no posted hours. I arrived and set up at sunset, around 4:30 pm ET and operated from 5 pm until 6 pm. It gets dark here early in the Northeast US in November.

Another challenge is how to manage and string up 144’ of wire. Brian suggested an inverted V over a tree branch in his write up. There were no trees nearby, so instead I used a Spiderbeam fiberglass pole secured to my Jeep to get the feed point up in the air about 25 feet. I used RG58 cable from the feed point to the radio.

Finally, I used one of my $3.00 Home Depot electric fence posts to secure the far end to keep it tight and up in the air and set up the antenna as a sloper. I laid out the counterpoise on the ground under the sloping wire.

By the time I had all of this set up, it was getting dark. I connected my Elecraft KX3 to the other end of the RG58 cable and to my surprise and delight, I was already receiving stations.

My KX3 has a built-in ATU and one tap of that ATU button and it tuned to 1.0:1. I started the activation right at 5 pm local time and in about 15 minutes, I had six QSO’s on 160 meters.

The PSK Reporter map showed me being received by stations on the dark side of the gray line in the Northeast. It was pretty much what I expected for QRP power on the low frequency. Then, the next ten minutes things were quiet. It appeared I had gotten everyone who could hear me.

Since this is a random wire antenna, it should work on all bands so I decided to test it on 80 meters. Again, the KX3 tuned right up and I got six more QSO’s. I was surprised to see Del, N2NWK from Washington, DC pop up on JT Alert. I have a an alert set for stations calling CQ POTA. Del was also at a park. I called and he answered and we ended up with a park to park. Anyone who knows Del knows that when you hunt him, he’s usually activating at a two-fer, at least. When I checked my hunter log afterwards, I saw four parks listed from him (a four-fer?).

At this point in the activation, I had gotten the ten QSO’s that I needed to call the park activated. I thought, let me try the VK160 on 60 meters. I re-tuned the KX3 and got five more fast QSO’s. The antenna worked great.

Before I packed up, I decided that I really wanted at least ten contacts on 160 meters, which was my original goal. I went back to 160 meters, now close to an hour later than when I began the activation, and easily added five more new QSO’s to the log. Maybe propagation had changed the later/darker it got or some new hams were on the band who weren’t on earlier, but I was satisfied to have gotten more than 10 on the top band.

The Results

Here’s how I did. Green pins are QSO’s on 160 meters, blue pins are 80 meters and the pink ones are 60 meters (click image to enlarge).

Conclusion

The “Top Band” activation was a success! The VK160 worked flawlessly, thank you Brian, K3ES for posting your design and providing the inspiration to activate on 160 meters.

My POTA “My Stats” page now shows 11 digital QSOs on 160 meters that I didn’t have before. I love conquering new challenges and given the challenge of going mobile with an antenna that will actually work and tune up on that low of a frequency at a park that won’t make you leave at sunset, well… that was quite an accomplishment!

Thank you to the 22 hunters (11 on 160 meters) who helped make it a success, including my friend Del, N2NWK in Washington, DC.

Conrad’s Kayak POTA Activation on Minnie Island

Minnie Island K-1698 Kayak Activation

by Conrad (N2YCH)

9/1/2023

As many readers know, I am on a Parks on the Air (POTA) quest to activate all references in the state of Connecticut. There are 136 parks, and four of them are only accessible by boat. You may have seen my recent field report here on QRPer.com about activating three islands located in the Connecticut River. For those islands, I enlisted professional help from a boat captain with the navigation experience and proper tools (like radar and maps) to access those islands.

The final boat-only accessible island is Minnie Island, located in the middle of Gardner Lake in the town of Salem, Connecticut. I DO have experience kayaking on a Lake, thanks to my uncle, who has two kayaks and has taken me out on Tillson Lake in New York’s Hudson Valley a number of times. Unlike the challenges the river posed, I felt like I could manage the lake on my own. I did need a kayak, though, which I didn’t own.

I had to do some kayak research then. In case you didn’t know this, different kayaks have different specifications on how much weight they can hold. I’m a big guy, six foot five inches tall. Add me, plus a backpack of radio equipment, and I needed to be sure I didn’t sink.

I started on eBay, looking for people selling used kayaks. There are all different kinds of kayaks. Some made for the ocean and dealing with waves and others for casual lake paddler. Some have rudders, some have small, sealed cockpits and some even have motors. I had no idea how serious you could get with all of the accessories and options. I was really looking for something simple.

After striking out on eBay, I found a fishing supply store at the end of the Connecticut River that also had kayaks you could rent. I visited their web site and was happy to see that they were having an end of season clearance sale, where they were selling their rentals. I visited their shop and after looking at my options, I ended up buying an Old Town Vapor 10 kayak. It came with a paddle and life jacket and it was 50% of the price new. A great bargain. The added benefit is now I own my own kayak…a friend suggested that now that I do, there might be IOTA activations in my future.

What sold me on the Vapor 10 was the open cockpit. No trying to squeeze myself in and plenty of room to bring a backpack with the radio equipment in-between my legs. Also, I was able to fit it into my Jeep Wrangler.

Next stop, the Gardner Lake Boat Launch, which was about a 30 minute drive North. Continue reading Conrad’s Kayak POTA Activation on Minnie Island →

Connecticut River Island Activations

by Conrad (N2YCH)

August 22, 2023

I’m on a POTA quest – activate all references in the state of Connecticut. There are 136 parks in the state and four of them are islands, only accessible by boat. Three of which are in the Connecticut River: Dart Island (K-1659), Haddam Island (K-1673) and Selden Neck State Park (K-1714).

I don’t own a boat. Plus, even if I did, I’m not sure I’d be brave enough to tackle the Connecticut River on my own. I have no experience navigating these waters, and it’s a real river, more than you’d want to try with a kayak with the currents and all. Even the POTA web pages for these islands warns “Boating experience and channel knowledge recommended.”

This created a dilemma –  how do I get to and activate these islands?

I strategized for a while and decided on chartering a “river cruise” boat who actually listed visiting Dart and Haddam islands as part of their services on their web site. The boat captain hadn’t visited Selden Neck, so that was new, even to him. However, he had a radar, and depth finder on his boat that mapped the channel and gave us the depths of the waters near each island. His boat drew 3 feet, so we had to have at least that much depth in each place we stopped. He also had a small “Achilles” boat that connected to the back of the cabin cruiser that we used to get ashore.

We left from a marina that was directly across the river from Dart Island but decided first to head South to Selden Neck and then work our way back North to Haddam and Dart.

Putting aside the island access for a moment, I also had to strategize on what gear to bring along to do these activations. I am primarily a digital mode activator and have used the Elecraft KX3 and AX1 antenna in many of my travels where I needed a light kit.

However, I thought, I can use the KX3 but take along a more efficient antenna. I used my Buddipole tripod and mast with a versa-T and a 17’ 9” Alpha whip antenna and a 15’ counterpoise elevated off the ground with a Home Depot electric fence post.

Because the mast elevates the versa T to 11’ high, and the telescoping whip at another 17’ 9”, I was able to get the antenna nearly 30’ off the ground to the top. It was easy to pack and carry and provided better coverage than the AX1 would have. You’ll see just how good QRP on FT8 can be in my Dart Island coverage map.

Equipment List:

Once I decided on the KX3 and the Alpha telescoping whip, I packed my backpack with the computer, cables, the radio, batteries and extra antennas. I always have the AX1 and a Packtenna EFHW as backups and they fit easily into the backpack. Two bags would need to make it from the boat to each island, the radio gear with computer and the antenna bag with the tripod and telescoping antenna. To be safe, since it would not be easy to do this again if something didn’t work, I brought along an entire backup system, packed in a second backpack with an Icom 705 and my spare laptop.

One of my goals with POTA is local discovery, and my boat captain was very knowledgeable about the river and the various sites along the shores. I learned that a manufacturing plant owned by Pratt and Whitney still uses water from the river as part of their manufacturing processes and also that there was a sea plane airport along one bank. I saw an automobile ferry along the way that I had no idea existed and saw the site of the former Connecticut Yankee nuclear plant that was decommissioned in 2004.
