POTA and RaDAR on the Florida Gulf Coast

Chris VA3ECO, Dennis WA6QKN, and I had a fun adventure Saturday, February 15th operating Parks On The Air and riding our bikes. We met at Grayton Beach State Park and set up at a pavilion next to the lake. I had all my gear, including an Icom 7100 and a battery in my bike trailer. Dennis and I unpacked the tuner and poles and set up a 39-foot antenna wire. My 25-foot pole supported the far end. The rig end had a six-foot pole to raise the wire above the ground.  The radiator came down the short pole and was terminated at the tuner. We spread out a couple of 30-foot counterpoise wires on the sand. I put a spot on the POTA site. The contacts on 40 SSB came quickly. We stopped at 22 since we wanted to start our bike ride to the next park. Chris had a 17-foot telescoping whip mounted to his bike and his Yaesu 857 in the basket. It did not fair very well on PSK due to RF feedback problems. Chris did get an SSB contact on 20 meters. 

Our modest 39-foot wire antenna faired well.
We discovered that Highway 30-A toward Top Sail Hill State Park was closed. Therefore we rode seven miles East to Deer Lake State Park. The hour journey took us through the Watercolor seaside community. At lunchtime, there were throngs of pedestrians and other bikes on the path. The bell on my bike came in handy to part the crowd.

Staging our bikes at Grayton Beach
Deer Lake State Park has a boardwalk out to the beach. Dennis and I set up at a bench stop along the way. We strapped the 25-foot mast to the railing. Once again, we spotted ourselves on the POTA site for 40 meters SSB. We had a flood of 66 contacts in that many minutes. Chris set up his bike station further along the boardwalk. He moved the whip to the bike handlebars and got eighteen contacts on 20 meters SSB.

We all felt good that we took advantage of some beautiful blue sky weather, played with radios, and got some exercise. We made almost one hundred Parks On The Air contacts altogether. I believe the bike, trailer, and Icom 7100 are viable for the RaDAR Challenge. Our ride between parks would take up two of the four hours. However, doing multiple parks also fits into the Florida State Parks on the Air Contest on the same weekend. We have a month to mull over the options. The RaDAR Challenge is April 4th of this year.

N4Y Winter Field Day 2020 Outing from Falling Waters

This year we had a setup similar to previous Winter Field Days at Falling Waters State Park near Chipley, FL. At campsite 5, Linda and I had a camper. We also had a tent for operating. Chris VA3ECO and Dennis WA6QKN used the tent for sleeping quarters. Tom WD0HBR and Sandy joined the group for Friday set up and dinner at the Mexican restaurant in Chipley. George W4GHG brought his family on Saturday and made his first out of town HF contacts. Bob KK4DIV and Carla had a tent site and station at the other end of the campground. Visitors included Frank KC8VKA and Rick NZ2I.

The N4Y class/category was 2O. We used non-commercial power. Chris helped out with a satellite contact for 1500 bonus points. This year, I created a logging program I call Cycle 25 Logger. It worked well enough. A couple of improvements were noted.

Carla and Bob KK4DIV camping and operating.
We balanced our time among eating, socializing, and operating. Chris warmed up Margot's Canadian Chili Saturday night. Chris also cooked eggs for breakfast. We found plenty of activity on the 80, 40, and 20-meter band. However, 15 meters was dead, which could have boosted our multiplier of 9X. Digital PSK-31 contacts were our biggest point maker.

Here is Bob KK4DIV's excellent video on Winter Field Day

The experience was enjoyed by all. We plan to combine camping and radio for the Florida QSO Party from Three Rivers State Park near Sneads, FL in April 2020.

My Solar Cycle 25 Reboot

I am attaching some significance to Solar Cycle 25 for my ham radio experience. I got my Novice and upgraded to general during Solar Cycle 20. However, I took a 25-year break from the hobby and missed the peaks for Solar Cycle 21, 22, and 23. In 2008, I got relicensed and I have been active during Solar Cycle 24. I see the upcoming Solar Cycle 25  as a great opportunity to personally enhance my amateur radio experience. I have not pursued aspects like contesting, DX, or Awards. So I should at least dabble and keep records in those activities.

My Splash Screen

Keeping records is my weakness even though I design databases at work. So my Cycle 25 Resolution is to log my contacts. There are dozens of computer log programs out there. However, since I have so much database experience, I will create a logging database for my own purposes. The first phase is to design the schema, tables, fields, and relationships. The more complete and correct the schema is, the easier creating the application or GUI will be. I actually teach a class on this at work.

My database schema diagram for Cycle 25 logging
The schema is coming along see the relationship diagram. You may glean something from it even if you have not studied databases. I am attempting to cover activations like POTA, RaDAR, Winter and ARRL Field Days, and Satellite Contacts for starters. Unfortunately, every activity and contest is a little different and will require specific fields to support them. Since I can write my own queries against the database, I can do statistics for each activity and overall statistics.

I also have considered multi-station operating at Field Days. It would be nice to use a networked central database for logging. I hear this is really tough to pull off in the field. Therefore, I am looking at an approach to synchronize copies of the logging database via sneakernet every few hours. This is a KISS approach. The database will be implemented in Microsoft Access since I have so much experience with that tool.

Solar Cycle 25 has not been officially started yet, although there are hints that it is on the way. A couple of Cycle 25 sunspots have been spotted. We just have to have faith it will start at all. It is up to the Sun. I am looking forward to it.

The November 2019 RaDAR Challenge and Parks on The Air

Dennis WA6QKN and I combined Rapid Deployment Radio (RaDAR) and Parks On The Air (POTA) with a fun bike ride in Wakulla County, Florida. Rapid Deployment Amateur Radio includes the outdoors, amateur radio, and movement. The RaDAR Challenge has a four-hour window to operate.
Our rail-trail route between Wakulla Station and San Marcos

We began at the Wakulla Station on the Historic Tallahassee St Marks Rail Trail POTA K-3661. When we put a spot on the POTA website the chasers came quickly. We had fifteen contacts in fifteen minutes on 40 meters SSB. That covered the required five for RaDAR and the required ten for a POTA Activation.

Then we mounted our bikes and headed 7.5 miles South on the Rail Trail. The radio gear was pulled in a bike cart. The equipment included the Elecraft KX2, Elecraft KXPA 100 amplifier, and a 30 AH Bioenno LiFePO4 battery. We used a SOTA Beams Band Hopper dipole for an antenna.

We arrived at the San Marcos de Apalache State Park POTA 3652 at St Marks, Florida. Once again, we spotted ourselves on the POTA website and got fifteen more contacts. Some were the same chasers as the previous stop.

Our radio gear

The bike ride was more than the required two kilometers, but it was a beautiful tree-lined journey. The trip down was 51 minutes downhill going South and 57 minutes uphill on the return.

Back at the Wakulla Station, I attempted an AO-91 pass but no joy. Dennis and I then found a Mexican Resturant for a nice lunch. Then we drove a couple of hours back to Panama City. On the way, we listened to Bill Browns WB8ELK's QSO Today episode.

The RaDAR Challenge's time constraint, radio contacts, and the required motion are challenging but fun. You have to try it to understand.

N4KGL's RaDAR Challenge Plans Saturday, Nov 2nd (Revised)

Dennis WA6QKN and I will combine Rapid Deployment Radio (RaDAR), Parks On The Air (POTA), and Amateur Satellites along with a fun bike ride. All of this will be in Wakulla County, Florida. Rapid Deployment Amateur Radio combines the outdoors, amateur radio, and movement. You are welcome to try RaDAR in the field or chase us on the radioPlease check for our spots. We will use N4KGL as our callsign. In RaDAR we need at least five contacts to move to the next location. For bikes, we need to move at least two kilometers. Our bike rides will be longer to get from park to park.

Our four-hour clock for the challenge will start at 1300 UTC, 9 AM EDT, with the SO-50 pass at the Wakulla Station Trailhead on the Tallahassee St Marks Historic Rail Trail (POTA K-3661). We will complete our five contacts on HF and ride our bikes to Wakulla State Forrest (POTA K-4643). Then continue the bike ride to Wakulla Springs State Park (POTA K-1862). Our HF contacts will be CW or SSB on  40, 20, or 17 meters. Please watch for our spots on 

Our rig will be the Elecraft KX2 with the Elecraft KXPA100 amp. I will use a bike cart to pull the rig and a 30 AH Bioenno battery. The antenna will be a SOTABeams Band Hopper Link Dipole.

We may continue this pattern beyond four hours to qualify for one of the RaDAR Awards sponsored by Parks On The Air.

Warthog Award: two RaDAR* transitions at or between entities during a 24 hour period.
Rhino Award: three RaDAR* transitions at or between entities during a 24 hour period.

My Go-To Antennas

Here are some antenna choices that serve me well. I operate portable more often than at home.

For horizontal polarization on portable ops, I am favoring the SOTAbeams BandHopper 40-30-20 meter link dipole. This is an extremely lightweight antenna that comes with RG-174 feedline. The good news is that the antenna does not weigh down the top of a telescoping pole. You will need to lower it to change the band using the jumper clips. I use the SOTABeams Tactical 7000 telescoping pole to support the BandHopper. There are lighter telescoping poles that would work as well. Note, I also like the LNR Trail Friendly End-fed for 40, 20, and 10 meters. I just have not used it lately.

SOTABeams Band Hopper at a campsite. Hard to see, isn't it.

For vertical polarization on portable ops, I love the N6BT Bravo 7K vertical. The Bravo 7K is self-supporting with integrated radials. When I am on the saltwater shore, the vertical is my top choice due to the saltwater effect. I also have had good success inland. It does not require a tuner. I find I can switch between 40 and 20 by changing the coil jumpers. The other bands require adjusting the element lengths. The adjustments are pretty straightforward.

For the ultimate in portability, my choice is the Alexloop magnetic loop. During the current solar minimum, it has been my backup, not my go-to. However, I have high hopes for the Alexloop in Solar Cycle 25 when the upper HF bands get better. You can't beat it for a quick and easy setup. The performance will surprise you even on 40 meters.

For FM Satellites on portable ops, I use the 2 meter/440 MHz Elk Log Periodic. I can disassemble it for easy pack up. It is also great for T hunts.

My Elk Sat Antenna. It was a cold January day.

For ARRL and Winter Field Days, the 80-10 EFHW has been very successful.  It is 130 feet long. I support it with a camo pole support and several Jackite poles.

My 80-10 EFHW. It is 130 feet long.

For Field Day on a small campsite, I designed a 100-foot long vertical loop fed a the bottom center with a remote tuner. It is supported by three 30 foot telescoping poles. The horizontal length is 30 feet, and the vertical sides are 20 feet. The lower wire is 10 feet off the ground. I have used this antenna at campsites and on island expeditions.

My Field Day 100 foot vertical loop uses three Jackite poles for support and a remote tuner at the bottom center.

At my home QTH, I had to rethink my antennas as Hurricane Michael took down my trees. I have chosen the N6BT V8, vertical sold through HRO, as my home antenna. It is similar to the N6BT Bravo 7K but uses an MFJ remote tuner at the base of the antenna. The antenna tunes well on 40 to 10 meters. The elements come off quickly for storms. I also remove the vertical element between uses to make the antenna less of a target for lightning.

My N6BT BT vertical in the backyard of my home. The horizontal elements are hard to see.

At my home QTH for receiving, I have a noise problem on the HF bands due to high-voltage lines running over my backyard property line.. The noise is intolerable on any antenna I put in the backyard. This encouraged me to try a receiving loop. I choose the W6LVP broadband magnetic loop with the T/R switch. For me, the loop makes HF operating at home possible. I mounted the W6LVP loop on a four-foot mast in the front yard near the house. I use a lightweight rotator to adjust the orientation to get a noise null. I use the N6BT V8 in the backyard as the transmit antenna.

Have fun with antennas!
