Hi, Can you please confirm that in case when the MP goes for transmitting the RX input is disconnected by the RL1001 relay? I'm trying to trace this back on the schematic but kinda crowded. I would like to make sure I'm not going to burn the receiver if I use any RX antenna. Thanks in advance. 73! Csaba HA3LN / HG3N http://ha3ln.hu/
