Hi Rich,

I also have a 221 and I devised a small relay and switch to open and 
close the keying circuit from the transmitter to the amplifier.  There 
are many mods available to accomplish a "standby" mode for the 221.  
Maybe someone knows if they are all centrally located and can give you 
the address.  Of course, you can always use coax switches to by pass the 
amp entirely when not needed.
