Andreas Eversberg 98ed54124a Fixed glitch in sound buffer space calculation
Sometimes the sound buffer (ALSA) returns a few more samples than we
sent to it. In this case we return 0, which means that no data has
to be sent.

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.
