What you are seeing is the TX DDS being let on during RX. This was done to improve the RX/TX/RX switching times.

On 17, 15, and 10 meters, there is a signal spike exactly aligned with the red "Zero Line'. This spike is visible on both the panadaptor and panafall screens. I don't see this spike on 80, 40 or 20 meters, nor is it visible on 12 meters. There seems to be no noise associated with this signal spike that I can discern. As I am viewing 15 meters right now, this signal spike seems to be constant and ranges from about 130dbm up to 100dbm. It is similar on 17 and 10 meters. Other than a visible oddity, it doesn't seem to affect that operation of the Flex-3000. Is anyone else experiencing this behavior? Anyone have a cure for the problem? I didn't notice this issue under 1.18.5 Flex-3000, Windows XP, 2.0.16 Gary Robertson W5SAT groberts...@austin.rr.com _______________________________________________ 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/ _______________________________________________ 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/
