Morning Bob, thanks for the tips and info, the page proved quite helpful. The VHF units are indeed the 56 in the 130 to 150 Mhz range, and the UHF units are the 77's, 406-420 Mhz range, I'm hoping they will make it up to the 434 Mhz range. I have 4 of the recievers that has already been converted and they seem to receive real well.
So if I take out the receiver from the vhf and place it into the uhf chassis that should do it. Can you tell me exactly which boards are which in the radios? I have nothing that tells me anything. Also, what must be done to get the radio to act as a repeater, so that when it recieves on 2 it will transmit on 440.
Also do you know what the value would be for the volume and squlech pots, as I have no control heads for the units. Might get lucky and find a service manual on the critters. Thanks again.

No mods are needed for U.S. versions either, so long as the last 2 numbers
on the model plate are 88 (UHF), 56 or 66 (VHF). 56 is the VHF model
that's actually spec'd to cover 2 meters, but the 66 radio should cover it
all too. I've had some issues with some 66 exciters not quite making it
down to 144.39 for APRS, but above 145 you should be OK.
What you want to do sounds real easy: just swap the RXs between 88 & 66 radios.

Check the "Mastr" list of PDF'd manuals at the Repeater-Builder website.
