The recording controls of the DDC and demodulator spectrum scopes
look
almost identical. However, their functions differ: The
DDC recorder
makes it
possible to record the entire DDC bandwidth (up to 4 MHz wide), while the
recorder in the demodulator panel serves to record the demodulated audio.
As each of the three virtual receivers has its own demodulator, each of the
three receivers can record audio independently and simultaneously, and
create separate audio files of three different stations.
The DDC spectrum recorder can be very useful in situations where there the
DDC spectrum is to be searched for interesting stations, or even when just one
interesting signal is of some significance and needs to be analyzed. A weak or
interference-obscured signal can thus be
“re-received” many times with
different demodulator filter bandwidths, notch filter or audio filter settings, to
arrive at the best possible demodulated audio.
