Just remember, if the other radio is a standard receiver, you are hearing the audio as modified by the IF response of the monitor receiver. If you tweak your TX response based on what you hear, you might just be building a complementary response to the filter in the monitor receiver. The transmitter in the Flex is a better and more accurate instrument than most receivers that use monolithic or crystal filters. You may just want to use a white noise source at the mic or line input and then tailor the response on the TX spectrum display rather than depending on another receiver. At least you will know what you have in an absolute sense. Oh! If you have RX2, use that. That will then let you monitor the signal with the PA in the loop. And then I think Bob is working on predistortion error correction for the analog circuits in the radios. With that you can end up with a high-quality source signal that is independent of what the other guy is telling you. -- 73 de Brian, WB6RQN/J79BPL _______________________________________________ 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.flex-radio.com/ Homepage: http://www.flex-radio.com/
