Mark, Sorry to hear that you are still fighting this problem. I think we were on the right track when this kinda ended last month, in that what you need to find is a Motrac series community repeater manual that might show the TLN5803A Master Decoder. I have not been able to turn one up yet.
I do have one question for you about the original configuration in these stations. Did they originally have a Diode Logic and a Multiple TPL Encoder card installed in them? I am sure you have answered this question already, but I really do not remember. If you still have my number, give me a call and we can talk on the phone. I have misplaced your phone number. 73, Joe - WA7JAW --- In [email protected], "n9wys" <[EMAIL PROTECTED]> wrote: > > Well, I got this thing all reassembled and tuned up on the new frequency > pair. a fellow ham (who used to work for the local Motorola shop) came over > with his service monitor and we tuned and tested the system.
