Pressing the
Recorder
button (DDC1 or DDC2) will reduce the height of the
spectrum scope at the bottom and utilize the extra space for the recorder
controls.
The recording controls of the DDC1 and DDC2 spectrum scopes
appear
identical. However, their functions differ: The recording controls of the DDC1
panel relate to the
DDC recorder,
making it possible to record the entire
DDC1 bandwidth (up to 64 MHz wide), while the
Audio recorder
in the DDC2
panel serves to record the demodulated audio.
AUDIO: As each of the three virtual receivers has its own demodulator, each
of the three receivers can record demodulated audio independently and
simultaneously, and create separate audio files of three different stations.
DDC: The DDC recorder can be very useful in situations where the spectrum
is to be searched for interesting stations, or even when just a single signal is of
such significance that it needs to be repeatedly analysed with various receiver
settings. A weak or interference-obscured signal can thus be “re-received”
many times with different demodulator filter bandwidths, notch filter or audio
filter settings, etc., to arrive at the best possible demodulated audio.
Recording starts when the
Recording
button
is engaged, and stops when
the
Stop
button
is pressed. A
Pause
button
is also available, to
temporarily pause both the recording and playback.
Playback starts when the
Play
button
is engaged. The
Loop
button
can
be toggled to keep playing a recorded file in an infinite loop.
The
DDC recorder
can record files with the extension “
.ddc
” format or “.
rxw
”
proprietary format. The
Audio recorder
will record in the standard Windows
wave format (extension “
.wav
”) or in the “.
wwv
” proprietary format. The actual
format can be chosen in the
Browse
file dialog or just by typing the file
extension in the file name edit box. For more details regarding the recording
formats, please see
Appendix G - Recording File Formats
.
The recorded file name can be set up using the usual Windows file edit box.
Pressing the
File
button reveals the Windows standard directory browsing
facility that can be used instead of having to type the path and file names.
If the “toolbox” button
next to the file name is activated, this will reveal a set
of useful controls specific to the recorders:
