I have a TH-78, have had one for about 15 years. Once in the 90's I 
tried the dtmf stuff with a friend, it worked. But I don't see the point 
in trying to build anything on top of the specific functionality offered 
by these 15 year old radios. My TH-78 has about had it anyway, 15 years 
is a long time for a handheld radio. I doubt there aren't many of these 
in use anymore.

I'm not saying that you shouldn't build or try new things, just 
questioning the rationale of basing them on specific, very old, radio 
modles.
