PIC&DTMF help

[Dave]

For those following this thread, Attached are the schematics, code and some pic's of the repeater link controller I designed quite a few years back for the radio club I belong to. I see no need to keep these a under wraps any more as the repeater owner has sold the repeater's to another club. I was the custodian for about 8 years or so and we had at any one time about 8 of these links in operation between two different repeater systems. I just thought the gentelman could use this code as the basis or at least see how to connect an external tone decoder to a pic. Enjoy... I think the code is documented pretty well as far as I can see. Maybe it should be submitted or promoted as an article...
