You sniped his last staement. He concluded by this that no protection scheme
was going to help, other than disconecting, as that voltage would damage
the reciever.

774 volts p-p without damage.

I gently disagree with your inclusion of the word receiver (with
respect to tolerating 774 volts). That's why the T/R switch has an
isolation spec that is much greater than 0dB. In receive mode the
transceiver might be damaged by voltages much less than 774 volts.

To confirm, simply transmit 1500 watts into your receiver.

Your analysis is probably more-or-less valid for 1500 watt
transmitters (or similar transceivers when transmitting).

Unfortunately, most transceivers have a very high duty cycle for being
in receive mode.
