Of Hotspots and Wi-Fi

By: WB3GCK
2 July 2024 at 11:06

I recently spent some time in Central Pennsylvania at my daughter’s house. Since I was going to be there a while, I brought along my Raspberry Pi hotspot. While I’m not really active in digital voice modes (or any voice modes, for that matter), there are a couple of DMR nets I like to check into each week. 

One issue I ran into in the past, is that my hotspot refuses to connect to their Wi-Fi network. Their Wi-Fi SSID has both an apostrophe and a space in it, so I’m guessing that’s the issue. I could have connected the hotspot directly to their router via an ethernet cable. Because of their router’s location, I would have had to move some furniture and put the hotspot in an awkward location. So, this time around I brought a little travel router to try another approach. 

Back when I was working, I had a TP-Link Nano router that I took on business trips. Typically, I would connect it to an Ethernet port in my hotel room to create a personal Wi-Fi network for my laptop and phone. A while back, I upgraded to the newer (and faster) TP-Link TL-WR802N travel router. I don’t travel nearly as much these days, so the new router hasn’t seen much use.

I brought the travel router along on this trip to create a wireless bridge from the house’s Wi-Fi to my personal Wi-Fi. The router’s Wi-Fi network has an SSID that my hotspot likes. I haven’t used that mode much, so I had to resort to the user manual to refresh my memory on how to set this thing up.

Actually, it was pretty easy to set up. It was simply a matter of connecting my laptop to travel travel router’s Wi-Fi to access the admin functions. From there, I set it up in the “Hotspot Router” mode. Then, I scanned to find the house’s Wi-Fi network and logged into it.

Testing the internet connectivity with my laptop, the speed looked good. I had previously added my travel router’s SSID and password to the hotspot, so soon after powering up I was hearing the sounds of DMR coming from my HT. This configuration worked great, and I successfully checked into a few nets during the week. 

The next time I go out there to visit, I’ll just need to power up the router and the hotspot, and everything should work. (Knock on wood)

No ground-breaking technological advances here. I just love when a plan comes together.

Weathering the Storm

By: WB3GCK
28 June 2024 at 19:31

While still on my extended stay at my daughter’s house in central Pennsylvania, I wanted to do some casual operating. So, I set up in the backyard to make a few contacts.

Today, I decided to give my Gabil GRA-7350TC vertical some air time. It’s been a while since I’ve used it. I set it up using the Gabil GRA-ULT01 MK3 tripod. I had forgotten how well engineered the Gabil stuff is. Anyway, I used four 15-foot speaker wire radials spread out on the ground. For the coax, I used 20 feet of RG-174.

I started out on 40M. Using an antenna analyzer, I got the SWR down as far as I could and let the KX3’s tuner do the rest. Taking a quick dial spin down the band, I didn’t hear much at all. Eventually, I came across WA2NYY activating a park in New York and called him. Despite the horrendous band conditions, he heard my 5-watt signal on the first call. Next, I heard an activator in North Carolina, but I had a rough copy. We still managed to complete the contact.

Next, I moved up to 20M and found the same crappy conditions. Eventually, I found and worked two more POTA activators.

I checked the POTA spotting page and saw that there were a couple of European activators on 15M. I tuned up the antenna and did a quick check. Nothing but dead silence across the band.

It was at that point that I checked the band conditions online and saw that there was a severe geomagnetic storm in progress. It showed poor conditions on all the HF bands. That certainly explained the lousy band conditions.

This explains the lousy band conditions today.
Yikes! This explains the lousy band conditions today.

Not being a glutton for punishment, I shut down for the day. Still, I was thankful for the four contacts I made with five watts of CW into an eight-foot base-loaded whip during a severe geomagnetic storm.

A Brief Activation at PA SGL 246

By: WB3GCK
26 June 2024 at 21:17

I mentioned in a previous post that I’m out in central Pennsylvania, doing some house sitting for my daughter’s family and taking care of my grand-dog. I wanted to get in at least one park activation while I’m here, but I didn’t want to leave the pup alone for too long. Fortunately, Pennsylvania State Game Lands 246 (US-8941, KFF-5862) is just minutes away.

I last activated PA SGL 246 back in 2022 and had 34 contacts. So, 10 contacts this time would not only qualify another activation for Parks on the Air (POTA), but it would also give me the 44 contacts needed for World Wide Flora and Fauna (WWFF). 

I rolled into the empty parking lot and quickly set up my 12-foot loaded whip on the back of the truck. My rig today was my trusty KX3 today (5W, CW).

There really wasn't much to photograph where I was at US-8941/KFF-5862. Just a gravel parking lot.
There really wasn’t much to photograph where I was at US-8941/KFF-5862. Just a gravel parking lot and some big boulders.

I started out on 40M and was greeted with about S2 worth of noise. I’m guessing it was coming from a power line that runs over the parking lot. Despite the noise, I made 10 contacts in about 13 minutes. Then things seemed to dry up.

I moved up to 30M for a while, but there were no takers. Determined to add at least one more contact, I went back down to 40M. It took a few minutes, but I finally got one more call.

Around that time, it was starting to get hot in the truck. I also neglected to grab my water bottle as I headed out the door. Doh! So, having narrowly exceeded my goal of 10 contacts, I packed up before I got too dehydrated. Besides, I had an errand to run before heading back to the house.   

After about 30 minutes of operating, the grand total today was 11 contacts. I don’t think I had any park-to-park contacts. 

I think this might have been the shortest activation I have ever done.

Field Day 2024

By: WB3GCK
23 June 2024 at 21:19

I’m currently out in the Harrisburg, Pennsylvania area for a week of house and puppy sitting for my daughter. My companion for the week is a five-year-old German Shepherd named Belle, who was adopted by my daughter and her family nine months ago. She’s a sweet dog, but she sometimes has some separation anxiety. So, I’m making sure my ham radio activities are short and close to home.

The first two days of my puppy sitting duty coincided with this year’s Field Day, so I did a little “backyard-portable” operating as category 1B. In my nearly 50 years of ham radio, this was my first-ever Field Day using my own callsign. 

My plan was simply to set up an antenna in the backyard and make a few contacts each day. The weatherman was calling for dangerously hot temperatures over the weekend, but there’s a section of the yard that has some shade for most of the day.

My (far) Better Half came out for the weekend. While I was surveying the backyard trying to determine what antenna to use, she suggested strapping “that fishing pole antenna” (aka Jackite pole) to my grandson’s basketball pole. Great idea! So, I strapped my 31-foot Jackite pole to the pole and used a 29-foot wire and my weather-resistant 9:1 UnUn. I ran 18-feet of RG-8x over to the two chairs that served as my makeshift operating position. My rig was an Elecraft KX3 (5 watts, CW) powered by a 6 Ah LiFePO4 battery.

I started off logging contacts in HAMRS on my cell phone. That lasted for about two contacts before I switched to paper logging. I wanted to keep things simple and forgo using my laptop, so paper logging was just easier for me than using my cell phone.

With temperatures in the high 90s (F), I only stayed out there for two brief sessions on Saturday. When a strong thunderstorm blew through, I called it a day.

After breakfast Sunday morning, I went back out to make a few more contacts before the weather heated up again. When I called it quits, I had 62 CW contacts in the log, including one DX station (France). 

My three hour effort didn’t break any records, but it was fun. I just wish the weather had been cooler, and I could have done without the thunderstorm. 

I hope everyone had a fun Field Day weekend.

20M Activation at Ridley Creek

By: WB3GCK
16 June 2024 at 21:26

Today I did something I don’t think I have done before: a single-band activation. Normally, I spend time on several bands. Today, however, I wanted to see how my 17-ft whip would perform mounted directly to the antenna mount on my truck (sans loading coil). 

I drove down to Ridley Creek State Park (US-1414, KFF-1414) this morning and set up in one of the picnic areas. After mounting the antenna, I broke out my antenna analyzer. Since the fully extended whip is approximately a quarter-wave on 20M, I wasn’t surprised by the SWR readings. With 15 feet of RG-8X coax attached, the SWR was a flat 1.45 across the band. So I fired up my Penntek TR-35 (5 watts, CW) and hung out on 20M for the next hour.

When I checked the band conditions, I saw the geomagnetic field was “unsettled.” Solar wackiness notwithstanding, I logged my first 10 contacts in about 12 minutes. European signals weren’t very strong this morning, but I still managed three DX contacts: two from Italy and one from France. An hour’s effort produced 26 contacts, including four park-to-park contacts. 

I’m planning to dust off a 25 year old 20M QRP rig and use it for a future activation. This antenna configuration might come into play for that. Stay tuned…

Public Service at the French Creek Iron Tour

By: WB3GCK
10 June 2024 at 18:30

Yesterday, I took part in one of my favorite public service events, the French Creek Iron Tour. Chester County ARES/RACES (CCAR) has been supporting this cycling event for more than 20 years. The French Creek Iron Tour benefits the French & Pickering Creeks Conservation Trust.

This is a large event, with distance options ranging from 11 to 100 miles. Because the event covers such a wide area, CCAR needed to provide radio operators at five rest stops and aboard eight support vehicles. The support vehicles are equipped with APRS trackers, allowing the net control operators to track their locations around the course.

My part in the event was pretty straight-forward. I was once again stationed at a rest stop in historic Yellow Springs, Pennsylvania. Because CCAR has an extensive linked repeater infrastructure, an HT was all I needed for communications.

Fortunately, there were no serious issues to handle. A few riders rolled into the rest stop needing bicycle repairs, and some riders required transportation back to the start/finish line at the Kimberton Fairgrounds.

This is always a fun event, and the folks from the sponsoring organization are always a pleasure to work with.

(Antenna) Size Matters

By: WB3GCK
7 June 2024 at 19:59

I went back to Marsh Creek State Park (US-1380, KFF-1380) for a quick activation this morning, and things got off to an interesting start. After setting up my trusty Penntek TR-35 (5 watts, CW) and 12-foot loaded whip, things just didn’t seem right. My SWR on 40M was high, and even my Elecraft T1 antenna tuner couldn’t get it lower than 3:1. 

I started checking cables and connections, but everything looked OK. Heck, it’s not a very complicated antenna, so there isn’t much that can go wrong. When I got out of the truck to change to another antenna, I noticed my 12-foot whip looked a little shorter than usual. I took the whip off and immediately found the problem. In my haste to get set up this morning, I neglected to extend the top section of the telescoping whip. Doh! Once I pulled the top section out and re-installed the whip, all was right with the world again.

Despite getting off to a slow start, my results weren’t too bad (by my standards). I finished with 36 contacts, including one known park-to-park contact. I had one DX contact with IW2NXI.

I finished my activation just in the nick of time. An hour after I got home, there was a major geomagnetic storm in progress. Timing is everything.

Back to Valley Forge

By: WB3GCK
2 June 2024 at 20:44

I almost talked myself out of this activation today. We had a long day yesterday at a family function with about four hours of driving, so my initial inclination was to take it easy today. In the end, the POTA urge was too great to deny, and I’m glad I went.

I drove over to Valley Forge National Historical Park (US-0761, KFF-0761), which is just a couple of miles down the road. It had been about five months since my last visit, so I was overdue for an activation here. 

Using my Penntek TR-35 (5 watts, CW) and 12-foot loaded whip, I started out on 40M. The signals were surprisingly strong this morning. My activation kicked off with a park-to-park contact with N1BS up in Rhode Island.

Forty and 20M produced most of my contacts this morning. I ended up with 39 contacts with 6 park-to-park QSOs. I had four DX QSOs: two with Italian stations, and two with SM4BNZ in Sweden on 20M and 17M. 

I also had a nice park-to-park contact with fellow QRPer, AA4XX. It had been a while since our last QSO, so it was good to hear Paul on the air this morning. 

After about 90 minutes of operating, the bands seemed to dry up, so I packed up and made the short drive back home. 

In the end, it was a fun morning, so I’m glad I went.

Hanging with the Heron

By: WB3GCK
31 May 2024 at 20:08

Since I’m slowly sneaking up on POTA “Repeater Offender” status (20 activations) at Marsh Creek State Park (US-1380, KFF-1380), I made a quick trip back there this morning. Unlike the rainy weather I encountered last time, it was a beautiful, clear morning. 

Since it was a weekday, the parking lot at the Western Launch area was pretty empty. When I got out of the truck to set up my antenna, I noticed a large heron. Last time, he was patrolling the shallow, marshy area near my parking spot. Today, he was proudly standing on the dock, surveying his domain. I snapped a couple of pictures of him and continued setting up.

I went with my usual setup: my Penntek TR-35 (5 watts, CW) and my 12-foot loaded whip. Starting on 40M, it took all of 12 minutes to make my first 10 contacts.

I had some errands to run, so I kept it short. In a little more than an hour, I logged 22 contacts. There weren’t any park-to-park contacts, but I did log four European stations (Italy, Sweden, Czech Republic, and Slovak Republic) on 17M. 

The heron eventually flew off. Like the heron, I took off, too—for home, that is.

Have a great weekend!

Holiday Weekend Activations

By: WB3GCK
27 May 2024 at 20:28

Over the course of the long Memorial Day weekend, I got in two short activations. As expected, there was a lot of activity going on at the parks. Parks in this area get a little busy on holiday weekends. 

Ridley Creek State Park (US-1414, KFF-1414)

I rolled into Ridley Creek State Park early on Saturday morning. Even at 0900 local time, the park was fairly crowded. I was going to operate from a picnic table, but given the number of people there, I decided against that. Between the hikers, dog walkers, mountain bikers, and folks setting up for picnics, it was a busy place. 

Using my Penntek TR-35 (5 watts, CW) and 12-foot base-loaded whip, I logged 27 contacts. Most of the contacts were on 40M and 30M, with just one on 17M. No DX today, but I had three park-to-park contacts. After about 90 minutes, I packed up and headed home.

Norristown Farm State Park (US-4363, KFF-4363)

On Monday, I had another early activation, this time at Norristown Farm State Park. As I expected, there were quite a few people at this park taking advantage of the holiday. 

This activation was almost a carbon copy of Saturday’s. I used my TR-35 and 12-foot loaded whip, and once again, I made 27 contacts with three park-to-park QSOs. Like the last activation, 40M and 30M were the most productive bands for me. 

This time, though, I worked two European stations (Italy and Sweden) on 17M. These were my first DX contacts in more than a month, so I was glad to be out of my slump. 

I hope everyone had a happy and safe holiday weekend. Be sure to take time to honor those who paid the ultimate price for the freedoms we enjoy.

A Tool for Dual Activators

By: WB3GCK
22 May 2024 at 11:09

I was first bitten by the parks bug, taking part in ARRL’s National Parks on the Air (NPOTA) program in 2016. When NPOTA ended, I started activating parks under the World Wide Flora & Fauna (WWFF) program. When Parks on the Air (POTA) came along, I started submitting my logs to both programs—and still do. 

Since POTA and WWFF are separately administered, there are some significant differences between the two programs. One notable difference involves the park designators. In some cases the park numbers are the same, but often they’re different. For example, the designator for PA 246 State Game Land is KFF-5862 in WWFF and US-8941 in POTA. Sometimes a park will be in one program but not the other. 

Fortunately, Al Zelna N3KAE has provided an online tool that makes it easy for “dual activators” to cross-reference the WWFF and POTA park designators in the U.S. and Canada. Visit the CQ Parks.net website to check it out. 

Dual Parks North America

If you aren’t familiar with WWFF, it’s the original Amateur Radio parks program. In its current form, WWFF dates back to 2012, but it has roots going back to about 2008. While POTA has seen tremendous growth since its inception, WWFF is still very popular in Europe and other parts of the world. When band conditions are good, a spot on the WWFF site or a DX cluster will often generate a European pile-up. It sure is fun having a bunch of DX stations chasing my little QRP station.

Have fun out in the parks, however you activate!

April Showers at Marsh Creek State Park

By: WB3GCK
18 May 2024 at 20:16

Lately, most weekends have been rainy around here. The forecast for tomorrow is much better than the rain today. Unfortunately, family obligations gave me no choice than to activate today.

I headed over to Marsh Creek State Park (US-1380, KFF-1380) early this morning, to avoid heavier rain later in the day. Despite the lousy weather, there were a lot of cars in the parking lot.

The rig today was my usual Penntek TR-35 (5 watts, CW) and my 12-foot loaded whip. As is my usual practice, I started on 40M. The band predictions forecasted poor daytime conditions on 40M, but that wasn’t my experience. Although some of the signal reports I received were lower than usual, I logged my first 10 contacts in about 13 minutes. My first contact was in Georgia, so that’s not too bad for 40M. The 30M band also seemed to be in decent shape. 

When I moved up to 20M, I found some annoying broadband noise across the band. I’ve never encountered that here before, so I was wondering if there was a hybrid vehicle or something in the parking lot. I skipped 20M and moved up to 17M. The band was nearly devoid of activity, and 15 minutes of CQing failed to produce a single contact. While I was CQing, though, I passed the time by watching a large heron wading by. I went back to 40M to finish up.

My final tally was 32 contacts, three of which were park-to-park. I didn’t have any DX contacts this morning, but there were some highlights:

  • I had park-to-park contacts with KD8IE on two bands.
  • I worked my friend Frank N3FLL. I talked to Frank on a local repeater on my way to the park and gave him a heads-up. He found me on 40M.
  • I worked Al N3KAE on 40M. Al is the Regional Coordinator who uploads my WWFF logs for me. It was great to add him to the log.

My setup withstood the rain pretty well this morning. I used a piece of pipe insulation on the passenger side window, where I fed the coax through. The fit could have been better, but it kept the rain out. Once again, I used a plastic bag to protect my homebrew coil. When I took the antenna down, I used a chamois cloth to dry the whip as I collapsed it. That worked pretty well.

Better but Not Great

By: WB3GCK
13 May 2024 at 18:19

I had another rare opportunity to activate a park on a weekday. After all the solar wackiness over the weekend, I checked the band conditions before I got started. The numbers looked better, but I still expected to encounter some flakey band conditions.

I rolled into Ridley Creek State Park (US-1414, KFF-1414) and started setting up. Once again, I used my 17-foot MFJ-1979 whip and homebrew loading coil. Thinking I would need all the help I could get, I went with the longer whip. The rig was my Penntek TR-35 (5 watts, CW).

About a minute after spotting myself, I received a call on 40M from another activator. Another hunter called about a minute later. I was off to a good start, right? Not so fast! After those two calls, things really slowed down. 

I split my time between 40M, 30M, and 20M, and it took me about 45 minutes to make my first 10 contacts. In fact, I thought number 10 would never happen. 

An hour’s effort produced 15 contacts with 3 park-to-park contacts. Sadly, there were no DX contacts to be had. Happy to have salvaged the activation, I packed up and headed home.

Hopefully, the bands will get back in shape soon.

Drive-on Antenna Mast Mount

Back in December, Becky Schoenfeld W1BXY, Editorial Director for ARRL’s On the Air magazine, asked me if I would be interested in writing a detailed set of step-by-step instructions for my Drive-on Portable Antenna Support. Naturally, I said I would.

I submitted my manuscript, along with an all-new set of pictures. The article was published in the current issue (May/June 2024) of On the Air (pages 20-22).

If you’re interested, have a look. ARRL members have access On the Air as part of their membership.

MFJ-1979 and the Junk Box Coil

By: WB3GCK
10 May 2024 at 17:58

I’ve been toying with buying a 17-foot telescopic whip for some time now. I didn’t really have a pressing need for it, since my 12-foot whip has been doing a great job for me. As a result, I kept talking myself out of buying it—until now. When I heard the news that MFJ was shutting down production, I figured I might as well buy one while they’re still available.

With no additional matching, you can adjust the MFJ-1979 to cover the 20M band and higher. I figured this whip coupled with my “Junk Box Coil” should easily cover 40M through 20M with the antenna fully extended. The four-foot height advantage over my 12-foot whip, should yield some performance improvement. With my older, larger coil, operation on 80M might be possible.

To test my assumptions, I made a trip to Evansburg State Park (US-1351, KFF-1351), where I was one activation away from a POTA “Repeat Offender” award. Like my last visit, it was raining, and I seemed to be the only one in the park. 

I set up the 17-foot whip and coil on the back of the truck and quickly identified the proper tap for 40M. I used a Sharpie pen to mark the tap location. (The coil now has two sets of marks.) Despite an impending geomagnetic storm, I made my first 10 contacts in about 12 minutes. Not too bad for an early activation on a Friday morning.

After about 25 minutes, I switched to the 30M band and marked the tap location on the coil. I picked up eight contacts on 30M before giving 20M a try. It was no surprise that the SWR was a flat 1.5:1 with the entire coil bypassed. Although conditions on 20M seemed a little weak, I logged five more contacts before pulling the plug. I ended up with 25 contacts in the log. No DX or park-to-park contacts today, unfortunately. 

For part of the activation, I used a plastic bag to keep the rain off the coil. When I got home, I brought the coil and the whip inside and dried everything off. While I had the whip extended, I measured the actual length. By my measurements, it’s 16 feet 11 inches long. 

Based on this brief test, I made a few observations:

  • Compared to my older 12-foot MFJ whip, I don’t think the quality of the MFJ-1979 is as good. The older whip just seems to telescope more smoothly. Some online reviews mention problems keeping the antenna from collapsing after using it for a while. In an effort to avoid problems like that, I’ll be extremely careful when extending and collapsing the whip. 
  • Performance on 40M, 30M, and 20M should be better than the 12-foot whip, given the additional length. A big difference? Given today’s band conditions, it was hard to tell.
  • With the 17-foot whip and my coil, I can cover 40M. 30M, and 20M without adjusting the length of the whip. However, the 12-foot whip gives me 40M, 30M, 20M, and 17M without adjusting the whip. This lines up perfectly with the bands on my TR-35. 

I won’t be retiring my 12-foot whip anytime soon. I think for most POTA activations, I’ll stick with the 12-foot whip out of convenience. For contesting and activities like Winter Field Day, I will probably go with the 17-foot whip. I have an old 20M mono band QRP rig I want to put back on the air in the near future. The MFJ-1979 should be perfect for that.

Another Mixed Bag Weekend

This was another of those weekends that involved different aspects of ham radio. I was involved in a public service event on Saturday, and I got my QRP-portable fix on Sunday morning.

The public service event was the annual Northbrook Canoe Challenge. This event has participants traveling 9.5 miles down the Brandywine River by canoe. The event, which benefits the Cerebral Palsy Association of Chester County, Pennsylvania, is always one of my favorites.

Once again, I served as the net control operator for the event. Chester County ARES-RACES (CCAR) had 13 operators at nine locations along the course. Several local dive teams also took up positions along the course, to ensure the safety of the participants. 

This year, I was set up at the Northbrook Canoe Company, which is the end point for the course. The weather was less than stellar, with on and off drizzle throughout the event. The CCAR team, along with a paramedic, hunkered down under a large overhang off of one of the buildings. Communications-wise, this is a straightforward event. CCAR’s repeater system provides excellent coverage in the area, so the entire course can be covered using HTs. I was able to run the net from my camp chair with my AnyTone HT.

I neglected to take pictures of the Canoe Challenge, but I did snap this one of the WB3GCKmobile next to the Brandywine River.

Fortunately, there were no serious issues to be dealt with, and judging by the cheers at the finish line, the participants had a great time, despite the weather. 

Evansburg State Park (US-1351, KFF-1351)

On Sunday morning, I wanted to get in a quick POTA activation. The weather was worse than the day before, with chillier temperatures and a more steady rainfall. 

I rolled into Evansburg State Park and found the park completely empty—except for one crazy old ham. After setting up my 12-foot loaded whip, I draped a plastic bag over the loading coil to give it some protection from the elements. I used my trusty TR-35 (5 watts, CW) up in the cab.

For as early as it was (0900 EDT), the number of callers surprised me on 40M. I had my first 10 contacts in about 13 minutes. I operated for exactly an hour and spent most of my time on 40M. Moving up to 30M, I picked up three contacts there before shutting down. 

I ended up with 31 contacts, including one park-to-park contact that I’m aware of. No DX today, but the Canadian stations were really booming in. 

Towards the end of my activation, I had some rain coming in the passenger-side window where I bring the coax in. Normally, I use a piece of pipe insulation to help seal things up a bit, but I couldn’t find it in the truck. I have some more in the basement, so I’ll have to cut a new piece to fit the window. 

Now it’s time to dry off my antenna parts before putting them back in the truck for next time.

Activating and Visiting

I drove over to Norristown Farm State Park (US-4363, KFF-4363) for a quick activation. The bands weren’t very “QRP-friendly,” but I made the required 10 contacts plus another half-dozen for good measure.

I went with my usual setup: TR-35 (5 watts, CW) and my 12-foot loaded whip. After getting things setup, I tuned around the 40M band and heard Greg WA3GM booming in. Greg was operating from a POTA gathering at Evansburg State Park (US-1351). Since we were only about five miles apart, it was an easy park-to-park contact.

After making 13 contacts on 40M, I moved up to 30M. My only QSO there was with W3WJ who was operating from Tyler State Park (US-1430, KFF-1430) about 20 miles away (as the crow flies). Our signals weren’t very strong, but we completed the park-to-park contact. 

I finished up with 16 contacts, three of which were park-to-park. I made all but one of them on 40M. 

Since I wasn’t too far away, I stopped by Evansburg State Park on my way home. The POTA gathering, sponsored by the Pottstown Area Amateur Radio Club (PAARC), was easy to find. The plethora of antennas was a dead giveaway. There were quite a few local hams there, and a good time was being had by all. After saying hello to WA3GM, KB3SBC, and a few others, I continued on my way home.

We’re finally getting some warm weather here in southeastern Pennsylvania, so it was a nice morning to be out in the parks.

Back in Business

The past few weeks have been crazy. I mentioned in the last post that I’ve been going through some medical issues. While I still have a few issues to resolve, I’m doing well—well enough to get in a long-overdue POTA activation.

I drove up to nearby Evansburg State Park (US-1351, KFF-1351). I’m (slowly) closing in on a Repeat Offender award for this park, so Evansburg was an easy choice.

There was nothing special about my setup today. I went with my usual Penntek TR-35 (5 watts CW) and a 12-foot whip with my homebrew loading coil. This combination has always served me well, so why tamper with success?

The bands weren’t very “QRP-friendly” this morning. Starting off on 40M, it took longer than usual to make my first ten contacts. There was some static, which I assume was from some bad weather passing to the south. To make matters worse, a hybrid car parked a few spaces away, wiping out the 40M band, until the driver turned the engine off. 

Despite the less-than-stellar band conditions, my 90 minute activation yielded 27 contacts. There were two park-to-park contacts that I’m aware of. Only one European station made it into my log today. IW2NXI called me on 20M, but didn’t come back after I sent his report. Fortunately, Graziano called again later on, and we completed the contact. I heard another station (Sweden?) calling, but I just couldn’t get the whole callsign. I hate when that happens.

It certainly felt good to get back out to a park again. I really needed that. Hopefully, I’ll get back to activating more regularly soon.

I also want to thank those who reached out to see how I was doing. Thanks for checking on me!

Easter Activation

By: WB3GCK
31 March 2024 at 19:17

I wasn’t planning to activate a park today, but my (far) better half suggested I might want to. I have some medical procedures coming up and a bunch of other obligations, so I probably won’t have many opportunities in April. It had been a while since I last activated Marsh Creek State Park (US-1380, KFF-1380), so I tossed my radio gear in the truck and headed out.

For a holiday, there was a fair number of people in the park. I pulled into a spot overlooking the lake and started setting up. Once again, I used my Penntek TR-35 (5 watts CW) and my 12-foot loaded whip

I spent an hour operating on 40M and 20M, and the hunters were out in full force. Although band conditions have been better, Craig sure was a busy boy. I ended up with 52 contacts. With the QRN, it was tough copying some of the DX stations. Despite that, I still logged nine of them:

  • St. Maarten
  • France (2)
  • Slovak Republic
  • Italy
  • Sweden (2)
  • Finland (2)

Hopefully, I’ll be able to get back out there in a few weeks.
