I think I've been confusing old instructions, and the latest instructions... OK, all reset, PA set up again, and the RX level reset to -70dBm. I'm listening to the Russian frequency standard on 9.996MHz. Which is peaking somewhere about -120dB above noise, which is at about -140dB on the standard setting. Unfortunately, WWV isn't so good now, it being night over here. LOL. Ah well, maybe tomorrow... _______________________________________________ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
