Appendix G – Wide-band FM Option
“WFM” option makes it possible to receive wide-band modulated signals
(“broadcast FM”) on the G3XX receivers. On the standard G3XX receiver, the
wide-band FM capability is not included, because it is not possible to provide
this within the constraints of the 15 kHz instantaneous bandwidth of the
digitized IF signal and the DSP software processing power.

The WFM option is in fact a self-contained “hardware-defined” receiver. The
user can receive wide FM broadcasts, but cannot see the entire 230 kHz
bandwidth in real time. Instead, the real-time spectrum panel shows
demodulated audio spectrum. It is also not possible to perform IF recording,
but it is of course possible to make audio recording.
