Suspicions....."apparent".... Is the drop of qrn reciprocated with a drop of field strength transmitted. I've been chasing similar problems and found changes (to grounding) made a vast improvement to the local qrn that I'm plagued with (PLT adaptors I think!). Then I checked my antenna current, It had similarly dropped, and signal reports confirmed my suspicion. Subsequent changes to grounding have improved both S/N in and out. I'm still cursing PLTs though! -- Brian Duffell G3VGZ _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flexradio.com/ Homepage: http://www.flexradio.com/
