Ron, Sounds like RF getting back into the PC. I had had that problem also. Fixed it by proper grounding of everything, including the PC, to a common ground bus. Also, ferrite chokes on ALL cables going in & out of the PC.
Good luck. 73, Ray, K9DUR _______________________________________________ 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://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
