[op25-dev] Re: P25 reception and trunk tracking from sdr radios

This is true, however as I read the inquiry, he wants to following trunking
channels of an unspecified type and decode P25 audio.  Using OP25, P25
audio can be decoded, and using gr-smartnet, Motorola SmartNet 3600 baud
control channel data can be logged and recorded....so if someone were to
spend some time working on merging the functionality of the two, a Motorola
3600 baud control channel could be tracked and the audio decoded.

I for one would love to work on something like this, but my coding skills
leave _much_ to be desired.  Regardless, I would still help out any way I
can.
