IC-821h no full duplex in satellite mode
I have recently bought a second hand ICOM ic-821h, that doesn't seem to be capable of the full duplex in the satellite mode. Once transmitting on the sub band, I have no receive on the main one. Does anybody have any idea as to how to remedy? Thanks
Nicholas, yes, of course. As said I can receive all right on both bands. I can send all right on both bands. But while I can send on the sub band in the satellite mode (FUNC + REV or FUNC +NOR), RX n the main band is muted during the transmission, so I can't receive while sending.

There is a sub band mute function in the menu. Look at the bottom of page 46 of the manual. You can get the manual from the icom website.

Thanks Drew,
Just tried to turn off the sub audio and in the satellite mode it indeed completely mutes any receive. While when I have the sub audio on and tx in the sat mode, I still hear some noice, but never a signal that is there on the frequency. I ruled out a desensing as I have also transmitted into a dummy load and have the same behaviour.
