[Elecraft] KPA-500 from Orlando

  Bill,

I don't know how many lines you have connected between the THP and the 
K3, but the simplistic view would be to use a relay to switch the RF 
input between the two amplifiers and also place the non-selected one in 
Standby.  Of course that simplistic solution would require that both 
amplifiers have an input signal line to place the amp into standby 
remotely - many do not, but modern amplifiers should IMHO.  Older 
amplifiers typically have only a front panel switch.
