Hi --
After looking at the archives, I think I may need to use a different software branch, but
here's where I stand:
1. Downloaded OP25 from the oscomcom site.
2. Built without any problems on Mint 17.04 with Gnuradio 3.7.11. Computer is an i7
laptop with 8GB RAM. I'm using an RTL-SDR dongle for now; I can try a USRP but wanted
to start with the simpler hardware.
3. Cobbled up .tsv files for local P25 system (Ohio MARCS-IP, Montgomery County site,
C4FM). This site has 30 channels and the 2.4 msps rate of the dongle can't catch them
all, but I am covering the control channel pllus several more channels.
4. Scope.py seems to run fine with all windows looking proper. Selecting some tabs
causes timeout errors on the console, but those stop when I switch tabs..
5. I seem to be tuned to the control channel (853.600) and see a not-terrible
constellation.
6. But I don't see any traffic decoding, much less get any audio (I know that the 30
channels at this site are spread over a bandwidth greater than the RTL-SDR dongle can
provide; I can bring a USRP to the game but for now would be happy just to decode control
data.
I'd appreciate any help, particularly on what the scope.py command line should look
like. And should I be using a version other than what is on the Osmocom site?
Thanks much,
