Hi,
I have a KPA500 amp and have some issues with it. I ran on my Cushraft R-8 vertical with fault (SWR) problems. I went to use it on the VHF contest with my meager 3 element yagi and it faults out? Hunhh? Checked the VSWR with a meter and my antenna analyzer and it shows a 1.2 to 1 ratio. OK I thought there was feedback so I put a bunch of ferrite cores and even wrapped 8 turns on the coax (balun) to no avail. What gives? This was mainly on 6 meters but to some extent on other bands also. Checked VSWR with a meter on radio (FLEX 5000A). I think it's in KPA500 circuit. Any ideas? I'm a newbie here so not familiar with what's been discussed. Thanks.
73, Kent, K6FQ
