[Discuss-gnuradio] DTMF, AFSK1200 gnuradio block

[griff]

Hello all:

I'm new to gnuradio.  Is anyone working on a gnuradio block that can 
detect DTMF tones, or 1200 baud AFSK (packet radio)?
Can this be done (in python) using existing gnuradio filter blocks?

I've been using multimon (http://www.baycom.org/~tom/ham/linux/multimon.html)
to decode DTMF, etc., but I'd like to do it in gnuradio.

I see that gnuradio.org/trac/ticket/318 is titled "Support DTMF", 
but evidently this is some type of support needed by OpenBTS.
