AFC feature.
The AFC feature (Automatic Frequency Control) is available in FM and PCM-FM mode only.
When using the AFC function, the frequency offset on the received signal is compensated so that the
signal is centered on the FM demodulator slope.
When the IF filter bandwidth is above 7 MHz, the demodulator slope is wide enough to take into
account Doppler effects. So the AFC function is disabled.
Warning:
This function is usable only if the spectrum is symmetric. The use of data randomization is strongly
recommended.
