Hi all, This could be tangentially related to a K3 issue, or maybe K3 experts can give some insight here. FYI, when I am not using the amp, I can get 100W from my K3 with no problem. Please keep reading...
I have been using my AL-811 (not new, but new to me) successfully at 500W for the past few weeks. Recently (actually, the second time this has happened), my fuses both blew and I replaced them. Since I replaced them, behavior has not been typical. I can't get anything over 200W (most is in the 175W range). I use a tuner after the amp, and I know that the antenna is matched quite well to the amp, but my SWR meter on my rig (K3) is showing a high value. When I tune up at 20-25W I can get about 100W out from the amp. When I move to 50-65W I get < 200W. And there is clicking. I can't tell if it's a relay or if it's something else. So, the main issues are 1. High SWR from the rig to the amp (when the antenna is < 2:1 SWR to the amp) 2. Low power from the amp to the antenna Happy to provide other information if folks have ideas on where to look. Thanks. -john W4PAH ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
