Bob,
Thanks for the reply, I do not mute DTMF on the output because of those voices that register as digits. The only concern I have is that if I raise the decode time, those folks using features from their mobile radios might not be able to do so.James
You can do it, but you might not want to.
The DTMF decoder used in the 2A is an 8870, made by several companies. The decode speed is controlled by C81 (0.1 uF) and R58 (300K). Those are typical values for 40 mS decoding (telephone company standard). You can make R58 smaller to speed up the decode time. But the voice talkoff rate will increase, and in fact, many repeater owners do the opposite and slow down their DTMF decoders for that reason. Certain voices seem to register digits pretty well.
