WiNRADiO G69DDC User’s Guide
If the frequency of one of the other receivers does not fit into the current DDC1
spectrum bandwidth, that receiver becomes disabled and the frequency in the
tab turns red to indicate the disabled condition.
The position of all virtual receivers (or rather their demodulator DDC2
bandwidths) is shown as dark blue areas inside the DDC1 spectrum scope,
with the currently selected receiver highlighted.
If a receiver is tuned away from the current DDC1 spectrum bandwidth (and
therefore disabled), it will not be shown in the DDC1 spectrum.
By clicking on the receiver tabs, you can quickly alternate between receivers in
a similar way in which you would use the
VFO
function in a conventional
receiver. There is the additional benefit of being able to change complete
receiver settings including demodulation mode, bandwidth, notch filter, audio
filter, etc. without the need to keep reprogramming when switching receivers.
