I don't have the manual here, but on every radio I convert to duplex operation I have to strap the "RX OSC" line to the 10 volt feed, otherwise the RX signal goes away (replaced with noise, not a muted RX) everytime I key the TX. I'm assuming here that without 10 V on the "RX OSC" line there is no "RX OXC", hence no LO. Bob NO6B
