We have been operating this way with full break-in for many years using the KD9SV products. First it was just the "Front End Saver" which removes and grounds the incoming rcv antenna from your radio during transmit. As a "Fail Safe" the device also prevents the Amplifier from working by removing the PTT line to the amp if by any chance the relays in the KD9SV device fail to operate. Later it is now incorporated into the various RBOG and other Pre-Amp devices that KD9SV sells... through DX-Engineering.
Disclaimer Statement: Yes I am a friend of Gary's. Call me a more than happy customer. I complained many years ago after I fried the front end of my IC-765 radios a couple times and Gary started building these devices. They Work and I am happy. No more blown front ends no more blown pre-amps. John k9uwa > Just a note to say that years ago, I had a B&W Electronic Antenna Switch (I > think it was called) that had one or two tubes in it.
