This demodulator is supplied as standard part of the G305 receiver package. It features
AM, AMS (synchronous AM), AMN (narrow band AM), LSB, USB,
FM6 (6 kHz FM), FMN (15 kHz FM) and CW modes, with fixed bandwidths (the FMW mode is optional).
There is a real-time spectrum scope which shows the actual situation on the
An interesting feature is Software AGC (i.e. digital AGC, in addition to the conventional analog AGC).
The dual-loop AGC of the G305 receiver makes it possible to process the weakest as well as the strongest
signals with equal clarity.
As the power of an ordinary PC does not yet allow to process the bandwidth of a wide-FM modulated signal
(broadcast FM) directly, the option to receive wide-FM is offered separately. The Wide-FM Demodulator Option
is based on conventional hardware (i.e. it is not software-defined) as an independent "receiver in a receiver". If this option is installed
and selected, the real-time spectrum scope shows the demodulated signal audio spectrum instead of
the radio frequency spectrum.
