Thanks for that. I saw some posts in the -BB archives about the issues with 434 MHz ATV and the 435-438 MHz satellite subband many years ago, but had never encountered it myself at a hamfest or when operating from anywhere else. After seeing Clint's demos last year at the same site, I knew that he should have been able to hit AO-27 from there. I also forgot to mention I saw Christy KB6LTY at Palm Springs yesterday. I've worked her a few times on the satellites, including one occasion where she was with a group of Scouts and I was able to answer questions from a couple of them. You never know who you'll run into, especially at an out-of-state hamfest... (not that I can afford the time and $$$ to visit many out-of-state hamfests) 73!
