I would be using two Kenwood tk-760hgs one set to receive one to tx, and talking though a portable tk-280.
And yes I am with a fire department and is licensed with the FCC to operate and program on those frequencies. Just gotta put that out there before it comes up lol.
I was going to program the the mobiles the same way so as to make them a make shift like mobile repeater.
I was going to use the
SURECOM SR-112 repeater controller
And a mobile duplexer tuned to the frequency.
Plus, I have no idea what the cost would be on a set up like that. I would guess it's outside of our fire dept budget so we haven't really explored that option.
