The last thing in the world anyone should do with an HF amplifier is 
use an RF sensing system to switch the thing!

Timing problems are bad enough without waiting until RF appears 
to transfer the amplifier relay!

I don't understand the problem the person described. The Drake 
has an internal supply for the relay. Why does it need external 12v?
