Good Suggestion Shanon! I have actually needed those chips from time to time (thanks!)
What about this? I have a handful of dtmf pads from various IC2at, 3at and 4at (one other that is a knock off that starts with a "S"?) that was used in remote base projects. I wonder if I could make one of these work? What a great idea for programming these things (Arcom 210 ....btw) What would I need to make that work? Thanks, Robert KD4YDC
