Has anyone gotten and RLC-4 or 2a controller to accept high speed touch tones?? I have an encoder capable of well over 20 digits per second, but I plan to stick to about 15 digits/s. I would like to use this for control since I do not mute DTMF on the output.
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.
