Thanks!

I have a writeup of the system here:
http://lukeberndt.com/2013/using-a-hackrf-to-capture-an-entire-radio-system/
In short, my system uses a HackRF SDR and GnuRadio based program I wrote.
It follows the trunking command channel and spins up a recording process
every time a new channel is assigned for a talkgroup.
