K9OZ ham radio blog

I spent Saturday at the Dayton Hamvention and had a good time at the contest forum and at the hospitality suite of the SMC (SOciety of Midwest Contesters) on Saturday night. It was a great chance to talk contesting and station building with other contesters My only purchase was another keyer, plus some odds and ends. More on that keyed and a couple other things when I get home. - Posted using BlogPress from my iPhone

Ok, I got outside and worked on the STeppIR vertical this morning. As I suspected, the problem was with the coax connection to the antenna. As I kept trying different coax and radio combinations, suddenly everything worked again. In plugging and unplugging the coax and trying different combinations, I evidently cleaned the connector on the antenna. After it started working again, I went back and cleaned everything with Deoxit, and hopefully it will solve the problem. All I know is it's nice to have the vertical back. I did open the antenna, and will post some pictures shortly. - Posted using BlogPress from my iPhone

I've been using the SteppIR big vertical for about three years with 20 radials under it. It works great, but over the last winter an intermittent problem has shown up. It seems I'm somehow losing connection with the antenna. All of a sudden, the antenna goes deaf and won't tune. I can recalibrate it a few times, and sometimes it comes back. This happened again this week, and for the life of me I can't get it to come back. Last fall i opened the antenna up and did continuity checks, and suddenly it started working again. I guess that's what I'll do tomorrow. I may take some pictures and post here on my progress. So far, I've removed the coax from the antenna and attached it to a dummy load at the antenna base. I get a nice flat SWR reading when I do that, so it's not the coax. I also hook my Yaesu FT-817 directly to the antenna with about a 3 foot run of coax, and get nothing buy high SWR and no signal. So I know the problem is with the antenna. I suspect...

Took the Mini to Minis on the Dragon last weekend. Not much radio time, but did meet two other hams at the event. There were over 600 Mini Coopers there, by the way. Here's a nice shot of the car and antenna. I'm thinking of heading to Dayton next weekend. Not much radio time with all this travel.
