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.

Fixed performance issue with IIR filter
...
Passing samples with zero value (0.0) causes very slow processing of
IIR filter on my test machine 'nuedel'. I don't know why.
To solve this, I add a very small number to each input sample.

FM modulation: Never turn carrier completely off
...
This prevents IIR filter to become very slow for some unknown reason.
