I use the DX-Engineering RTR-1 which is the easiest and best solution
IHMO. It even provides protection by locking the RX portion out on
Transmit by loop the PTT amp cable. I have two of these units now and
use them on all the Icom radios. They even have a special momentary
toggle for check the TX antenna for A/B RX tests. Must have been
designed by a thoughtful amateur.
