Does the radio mute the audio or is the UHF receiver blocked by the transmitter's third harmonic?

I was trying to work AO-27 this afternoon...I thought the IC2720H would operate in "Full Duplex",..transmit on one band while simultaneously receiving on the other. I had my left band set on the uplink of 145.850 and the right band set to the downlink of 436.795 (adjusting for doppler). I was able to hear the downlink just fine. When I tried to transmit on the left band (set as the main band) the audio on the right band would mute. Thus, I was unable to hear if I was hitting the satellite. I have the sub-band mute feature set to off.
