Thanks for the replies about the shared-controller idea. Got several additional technical factors to think about now as I continue playing with this project...I've taken note of all suggestions received thus far and will take a day or two to consider those things and then finish the project.
As for the legal concerns, there shouldn't be a problem. The repeaters consist of one 2m, and one 440 Mhz. I can use the control receiver input line on the controller for the 440 side (the control receiver gets priority for all DTMF commands, over the repeater receiver line). At this point I don't think I'll do any additional work to prevent DTMF control from the 2m side though...I plan to send any DTMF commands through the 440 repeater anyway. --- In Repeater-Builder@yahoogroups.com, Steve Rodgers <[EMAIL PROTECTED]> wrote: > > I don't want this to become a flame thread but.... > > I'm not sure I'm completely wrong about this.
