[ICOM] 756 Pro3 Question

Simply use a very low current relay powered by 12VDC and have that trigger 
two other relays A & B that will each activate one of you amps.

Make sure that very low current relay is really low. I already had hang-up 
problems with a small relay triggered by the 756 PROIII internal switching 
controls. Had to use a diode and ferrite bead choke in the lead wire going 
to the socket on rear panel.

As long as you only have one amp on at a time, this should work .

Subject: [ICOM] 756 Pro3 Question


I just bought an Icom 756Pro3 and have a question for all you Icom gurus.

I have two separate amplifiers that I plan to use on this rig...One for
6 meters only and another for HF only.  Is there any way to set up the
amplifier keying circuits so that when I am on 6 meters it only keys up
the 6 meter amplifier and the same when I am on HF or do I just run them
in parallel and only power up the amplifier for the band I am currently
operating.  I have read thru the manual but cannot see anything like
what I propose to do.  Any help would be greatly appreciated.

Thanks, in advance and 73.
