CONNECT Tx ENABLEN TO A uC PORT PIN (possibly through a level converter) and forget about a relay. Yes, I found the original post a bit hard to follow, but I think what he was trying to say was that he is driving the CMX469's TxEnable direct from a port pin - but this pin is also driving a relay which is, presumably, simulating the radio's PTT (Push-To-Talk) switch...? That's the trouble with trying to describe a cicuit with words - it's always so much clearer to show a schematic diagram...! |
