Only one option can be active at a time. Each option invites you to enter a file
name, relevant to the type of task selected.
With the audio recording task, you can also enable and specify the parameters
of a
band-pass audio filter
. It is advisable to use this audio filter, especially
for narrow-band FM signal where de-emphasis (typically -6dB/oct) is usually
necessary, and where low-frequency signalling often introduces disturbing low
frequency components to the audio. Low and high cut-off frequencies of 300
and 3000 Hz, respectively, usually provide best results for voice recordings.
If you chose any of the two recording tasks, you can also specify situations
where the recording should pause – in order to save disk space and also to cut
out long pauses when playing back.
The five pause conditions replicate the main panel
Squelch
settings and
should be adjusted similarly. The signal strength setting can be used in
conjunction with any of the remaining four (i.e. the recording will stop if the
signal either drops below the specified level,
or
satisfies the other specified
condition).
For IF recording, only the signal strength condition is enabled, because no
modulation content processing is performed on the recorded IF signal.
Finally, to terminate a recording task, you have the following options to stop
the recording:
1. If it has paused for a longer than specified time.
2. After a specified time elapses.
3. If the file length exceeds a predefined value (in Megabytes).
