Andreas Eversberg b8352af84d SoapySDR: Minor debug output improvement 2021-12-12 10:53:26 +01:00
Andreas Eversberg 2d23c841a6 Cleanup SDR usage when no channel, but full spectrum is used.
Radio and TV uses full spectrum, so they set channels to 0, this will
define a center frequency only. The spectrum is then processed by the
applications and not by libsdr.

The sample rate must be a factor of 1e9, so that time stamps work
and signal has no gaps/glitchs.

Andreas Eversberg 423bc42429 Refactoring validity check and prefix processing of dialed number
Command line help shows how many digits and what prefixes can be dialed.

Giving a station ID via command line will be checked for being valid.

The number to call the mobile statione will be checked for being valid.

Prefixes that are defined for a nework will be removed from station ID

Multiple station ID lengths are supported:
 * C-Netz: 7 or 8 digits, depending on area code length
 * A-Netz: 5 or 7 digits; number is truncated to last 5 digits.
 * IMTS/MTS: 5 or 7 digits, depending on phone's selector switch.

Andreas Eversberg 7670b22118 Using "--limesdr" or "--limesdr-mini" will also set device to "lime"
This is useful, if SoapySDR supports other SDR devices, like sound card. In
this case "--sdr-device-args driver=lime" must be given at command line. Now
this is done automatically with "--limesdr" or "--limesdr-mini".
