Jessie, thanks for the input. On RTTY and other constant-envelope modes you can hear the RX antenna relay switching at the start of the tx and again when the tx ends. But on SSB it's really annoying as it continuously clicks (well, at least it protects the radio! HI). Just wondering why the RX antennas are not disconnected by the firmware while transmitting.
