Yep. A highpass BCI filter inserted in the RX signal path using the RX loop.
Like this one. I have never used it, so I do not know how well it works, but this is the type of filter you are looking for. http://www.dunestar.com/model400.htm -Tim ---- -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ross Stenberg Sent: Wednesday, April 02, 2008 12:09 PM To: 'FlexRadio List' Subject: [Flexradio] AM Broadcast on SDR-5000 Whenever I am on 75 meters AM during the day and it is quiet, I can hear an AM broadcast station that is about 5 miles from me which run 5000 watts. It is not a spur, but rather just a signal that I can hear no matter where the SDR-5000 is tuned. The signal will disappear if the antenna is disconnected and is definitely ingress to the SDR-5000 and not the external speakers. It is present on all bands. Not a big deal just can be rather annoying when all is quiet and I am on AM. It is not as if I am in the near field of a 50KW powerhouse. Any ideas? 73 Ross K9COX _______________________________________________ FlexRadio Systems Mailing List [email protected] 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/ _______________________________________________ FlexRadio Systems Mailing List [email protected] 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/
