WiNRADiO G3XX VHF/UHF Receiver
The Demodulator
The heart of the G3XX receiver is its demodulator. The demodulator is entirely
software-defined, implemented using optimized filtering and quadrature
demodulation techniques and executed inside the receiver’s on-board DSP. All
the functions related to the demodulator, i.e. demodulation mode settings,
volume control, IF filter bandwidth, IF shift, RIT, software AGC, AF squelch,
notch filter, noise blanker, recorder/playback and real-time spectrum display,
are grouped together in an area of the front panel of the receiver which is
referred to as the Demodulator Panel. This panel is in fact a separate plug-in
to the main receiver panel, and can be replaced by other demodulators, either
developed by WiNRADiO or third parties.
