	As I recall, VHF Amp is for powering a mast mount preamp via coax. Try

	VHF T8 is a good way to go to disable TX on 2M. There is a similar system in the FT-736R.

Thanks for the information.  I forgot about the FT-847's capability to apply 12V to the coax cable because I use DC-blocking coaxial lightning suppressors.  I run separate wires to power preamps and coaxial relays.  Those wires are all connected to rotor surge suppressors (40 Volt MOV's to ground).
