Appendix E – Professional Demodulator
The WiNRADiO G303 receiver has provision for additional demodulators, in
place of the supplied standard one. Installed demodulators can be selected
via the Demodulators top bar menu. Check the WiNRADiO Web site
www.winradio.com periodically, for available demodulators.
The Professional Demodulator which is available as an optional extra,
takes the concept of software-defined shortwave receiver a step further. The
main differences between the Standard and the Professional demodulator
are as follows:
• Additional demodulation modes (DSB and ISB)
• Continuously variable IF bandwidth (from 1 Hz to 15 kHz)
• User-adjustable IF filter coefficients and other parameters
• User-adjustable audio AGC
• User-definable IF bandwidth presets
• Interactive demodulator structure with two spectrum scopes and a
vector voltmeter
• Additional instrumentation (SINAD and THD meter)
• AF Squelch for FM mode
