I bet I can take *any* controller and connect
it in such a way it will not decode DTMF tones. ;-
That said, two things to remember about Motorola DTMF mics. First, the
bias was already mentioned. If the mic isn't getting voltage, how could
it ever produce DTMF tones? Second, many times the

True, but the reason was likely to prevent the 'button press' when the
PTT was active. How many times have you hit a button accidentally on a
DTMF mic? In the commercial world, most would not have understood what
happened - especially if the controller mutes DTMF (which most

So a port's DTMF decoder will look at a port even if BOTH COS CTCSS
logic signals to that port are invalid?
---Well, the decoders always look at the audio stream for a
particular Port. Now whether or not the processor ignores or pays
attention
