1) AFC does only work in NFM mode with a filter setting up to 30kHz.
2) It does NOT automatically retune the receiver to the nearest strong signal.
3) Real function of AFC: It tunes the IF filter's frequency automatically when an unstable
frequency is received. It does not change the receive frequency. Since only IF is changed,
there is no "visual" change on the control program's spectrum or frequency display. The
change can only be heard on "audio".
4) It only works if the sending station's frequency shifts are within the selected IF filter's
bandwidth. Example: IF=15kHz >> +/-7kHz, IF=30kHz >> +/-15kHz
