Eric, Yes, I do have the 5979A backplane. However, I'm NOT sure if I have a 5970 SCM, but I believe I do. I will check tomorrow when I get a chance. I believe that one has the LED on the front for the disable indicator, and has IC's on it instead of transistors, correct?

It uses a TLN5979A backplane instead of the more common TLN5644A. You MUST use the TLN5970A Station Control Module with the DVP backplane, as it has many critical connections that are different from the more common TLN4635B SCM. You can keep the Squelch Gate and Timeout Timer modules, since they are the same in both DVP and non-DVP stations. Remove all other modules, since they can only complicate matters. A few jumpers must be installed on the backplane to "normal through" the clear audio which normally goes to the DVP Control Module. I can advise you where the jumpers need to go, if you can verify that you have the TLN5979A backplane. The number should be stamped on the backplane (not the chassis) along the top edge of the board. Before you start modifying your DVP station, you really should get a copy of the manual, 6881036E40. 73, Eric Lemmon WB6FLY kbednar99 wrote: > > I'm working on a Micor VHF continous duty base, model C73RXB- > 3106BT/C756ADSP.
