The best way to find out is to start by turning off the power and running your station on batteries to see what noise sources are left, if any. If that got rid of the bulk of the noise sources then you have your work cut out for you to nail them down individually and kill them . The one caveat to that is that I have found that my laptop display is an emitter, especially when it is in the near-field pattern for the antenna (such as my operation in Dominica). The computer itself is a source you just can't eliminate. OTOH, I have found that wrapping the display completely in aluminum foil makes all noise sources disappear. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 br...@lloyd.com +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ 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/
