Ok I manged to get scope working but have a weak signal, getting a garbled conversation,
I used ./scope.py --args 'rtl=0' -N 'LNA;50' -S 960000 -139.4200M -o 2000 -q -2.0 -v 0 -V to run scope, but I have to have my fine tune maxed at -3000 to get anything and get the correct pattern on constellation,
What should I change in my command line(.scope.py) to improve the tuning? any ideas

Ok thanks, how do I find out my devices ppm? So if the RTL doesnt support the op25 grc file, what do you recomend? funcube maybe or a usrp

Change -q -1.9 to what your RTL PPM value is.
Forget about OP25 and GRC, it doesn't support it.

Well i finally got scope working, turns out the problem was when i plugged in my rtl it installed the dvb driver, so I had to use the sudo rmod probe command and remove the kernel
I have scope up and running , I want to listen to 139.5600,(mhz) its p25 1 non-trunked, but I cant seem to find it with scope, and my fft plot is in khz
Any sugestions on what to use for a ./scope command? Im using ./scope rtl=0 -f 139.5600M
Did anybody get the grc file I posted to work?
