I decided to travel a little further this time and head toward the Okefenokee swamp. this time I tried the Laura S Walker State Park. It was a five hour drive and about 320 miles but fortunately I was able to stay off the interstates for all but about 30 miles of the trip. The park is near Waycross, GA which recently suffered from severe weather. Even though it has been a while there it still plenty of evidence to attest to natures fury. The park itself was in good shape and I had a nice campsite.
I would normally use my 28.5′ vertical antenna but I had a power line that passed almost directly over my truck and camper. I could have requested a better campsite but in the spirit of FunComm I decided to work with what I had. Instead of my usual antennas I deployed a new antenna. A Diamond RHM-12. This is a manual screw drive type antenna that is only about 7 feet tall and covers 40 meters to 440 MHz. With additional coils it also covers 80 and 160 meters. I set it up away from the power lines and used a Chameleon Spike to set it into the ground. I also had 2 counterpoises about 20-25′.
I was a little concerned about its performance. Inside the camper I had My Lenovo Laptop and Yaesu FT-710 with an LDG tuner.
I had a Rig Expert Pro Stick antenna analyzer with me and I was able to get the SWR down below 2:1. I guess I could have monkeyed with to get it lower but since I had the tuner…
I have really taken a liking to the FT-710. It has been performing well and since the last firmware updates, it has become a little champ. It is winning my heart. The radio, tuner, and computer all worked well together. I only ran 25 watts of power as that is about the limit on the antenna using FT-8. I was going to work some CW but the days I was at the park the temps were up around 90 degrees, far from the 43 degrees the morning I left my home QTH. I ran the air conditioning and when it is on I have trouble copying CW. Years in Army Aviation and other loud occupations have affected my hearing.
How did I do? Surprisingly well. In a 24 hour period which included sleep time, I made 400 contacts (7 dupes). I made contacts in 46 states (Not AK, HI, MT or RI) and 34 DX entities! I think that’s a new record for me during a POTA Activation. I got as far west as Australia and American Samoa, and as far east as Turkey, Bulgaria, and European Russia. The bands were up and down and I had to make a few trips out to the antenna to adjust it when I changed bands.
I never expected that little antenna to perform so well. The RHM-12 antenna has been assigned to permanent duty in my antenna kit.
It’s important to take your gear out and use it. Understand how it operates under various conditions. Know what your gear can and cannot do. This is good to know having fun but becomes critical when more is at stake.
