I believe that's what the latest versions of PowerSDR do.. they run the Rx continuously, and gate the audio off during Tx time. More than a year ago (maybe 2 years), they did do the DSP in half duplex thing, and it had just the effect you describe, where you had to wait for a buffer to fill before you could hear anything. (worse than that, it made the *apparent* delay for QSK turnaround random, which is really, really annoying. >very best regards >Rob >AB7CF _______________________________________________ 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://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
