Had a 509 for years, so I got another at a ham fest, seems to work OK, except low power. 10M=.7 W 15M= .5W 20M=.5W 40M=.1W 80M=.05W Any help? Rig has been sitting for years, but it cleaned up nice, no mods as far as I can see. Would it help to unplug all the boards, and clean the prongs? Phil WB5PG
