Tones must NOT be distorted and are sent on the audio subcarrier of the signal accessing the repeater. Most commands take approximately 5 seconds to load from the control computer.
The touch tones generate a corresponding binary code, TT01 = $01, TT02 = $02, TT0.TT3 = $03 etc etc. The micro reads the binary code whenever it gets TT#. TT* is really only required if you have incorrectly loaded a code. The decoder is reset after completion of the operation. The total control program for the repeater is written in 6800/68HC 11 assembler.
