Andreas Eversberg 4810ff659f Osmo-CC: Fixed originator address info in SDP 2021-12-30 23:34:25 +01:00
Andreas Eversberg 3dcb7b34df Implementation of selective call for classic German 'Sirenensteuerung' 2021-12-12 10:53:27 +01:00
Andreas Eversberg 1bd471a703 When a transmitter is off, send absolutely nothing 
This is done by shifting away the transmitter from center (DC) freqency.
Useless code was removed, since there is nothing to be transmitted.

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
automatically.

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 case "--sdr-device-args driver=lime" must be given at command line. Now
this is done automatically with "--limesdr" or "--limesdr-mini".
