Since DTMF has two tones for each number, it would seem possible that
you could have some DSP detect the difference frequency of each pair and
then either adjust its decoders or QSY the receiver's VCO to get a lock.
There are a ton of small development boards like Raspberry PI that have
hardware that might be able to do this.
Has anybody got the AMSAT-bb daily digest to work through their e-mail
provider other than Gmail?
