RuntimeError: Unable to find any supported SDR devices

[Al Higgins]

Without looking too deeply, you have at least a couple of problems here:

1. No device is detected, do you have a supported SDR connected to your (presumed) VM?

2. You haven't specified a frequency for grgsm_livemon to monitor. You will get this by running grgsm_scanner first and using the frequency value vice ARFCN to initiate grgsm_livemon. Example: grgsm_livemon -f 950.0M

Hope that helps.
