[op25-dev] OP25 with AGC (automatic gain control)?

Hi

Currently I'm using a command line like:  ./rx.py --args 'rtl' -N 'LNA:49'
to adjust the LNA gain of the RTL-SDR. Is there a way to do AGC? Near me,
the 700Mhz channel is really strong, but 800Mhz is really weak. So AGC
would be very useful. Also if not easy, what other gain and ranges I can
adjust? What's the max value for LNA gain?

Thanks

James
