Wanting to take advantage of the excellent weather today, I drove up to Evansburg State Park (US-1351, KFF-1351) for a quick morning activation. I wanted to give my Gabil GRA-7350TC vertical some air time, so I tossed it into the truck and headed out to the park.
The picnic table I planned to use had been moved from its usual spot. Not wanting to drag the heavy table back to where it belongs, I set up at a table I have used previously. It’s close to a hiking trail, so I needed to make sure my radials wouldn’t be a trip hazard for passersby.
I set up the Gabil antenna on its tripod at one end of the table. To facilitate tuning, I set up my Penntek TR-35 (5 watts, CW) and Elecraft T1 ATU within arm’s reach of the antenna. I meant to bring a 3-foot coax along, but it didn’t make it into my backpack. A 10-foot cable was the best I could do, so I just coiled up the excess. (Note to self: Keep a 3-foot cable in the backpack.)
I started out on 40M, so I laid out a 33-foot counterpoise wire on the ground. I reached for my little SWR meter, but it wouldn’t power on. It had been a while since I had last charged it, so the battery appeared to be dead. I ended up adjusting the antenna for maximum noise in the receiver and used the T1 to do the final matching.
After I had a few contacts in the log, I changed over to 20M. I built my 33-foot counterpoise wire so I could split it into two 16.5-foot wires. After laying out the two counterpoise wires, I tried to peak the noise. No joy. I just couldn’t find a discernible peak.
Just then, I remembered I had a 12-volt power cable for the SWR meter. Duh! Why didn’t I think of that sooner? After temporarily disconnecting the TR-35, I used the battery to power the SWR meter. I quickly got the antenna adjusted to a 1.3:1 SWR. I reconnected the TR-35 and got started. (Note to self: Throw a Powerpole splitter in the backpack.)
The action was relatively slow-going this morning, but there were a fair number of activators on the air. After a little over an hour, I had 14 contacts, nine of which were park-to-park.
Despite some minor glitches, it was an enjoyable morning operating in the park.
