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.

Selecting Demodulation Mode

To select the demodulation mode, click the appropriate mode button in the

demodulator panel:
