OK, I have gotten some replys with Harris RF102 and RF101 shown. The amplifier I mentioned is not these, but it might be a variant of the 101, earlier model? The 101 had two 3-500Z i think, and this one has one 3-1000Z. It does have the rocker switches to tune and load though. Any one else have an idea? See my earlier post for the question... 73 K5PRO --
