WiNRADiO G315 VHF/UHF Receiver
34
To set up RIT, firstly tune the receiver precisely to one of the stations, until you
have perfect sound. Then press the RIT button and adjust the RIT frequency
increment (it is shown in Hz) to hear the second station clearly. You can either
type the increment value in the edit box (which is a slow way), or use the
up/down arrow keys, or the small slider located between the arrow keys, which
is the fastest way.
Then simply turn RIT on and off, depending on which station is
currently on air.
Recording and Playback
The G315 receiver’s demodulator has integrated recording and playback
functions. This facility makes it possible to record and playback the
demodulated audio in standard
“.wav”
files, as well as the modulated signal at
the IF level (
IF recording
).
The IF recording feature can be very useful in situations where the received
signal is of some significance and needs to be analyzed. A weak or
interference-obscured signal can be thus “re-received” with different
bandwidths, notch filter and noise blanker settings, to arrive at the best
possible demodulated audio.
Recording starts when the
Recording
button (red dot) is engaged, and stops
when the
Stop
button (green square) is pressed. The
Pause
button (two green
vertical lines) is also available.
Playback is done by pressing the
Play
button (green arrow), and the
Fast
Backward
and
Fast Forward
buttons complement the recording controls.
When the
IF
button is engaged, the recorder will record on the IF level instead
of audio. The recorded files will have the extension “.
if.wav
”.
The round arrow button, when engaged, causes an infinite looping when
playing either audio or the IF signal: When the recorded signal reaches the
end, the playback will restart immediately again from the beginning. This is
particularly useful when you are playing back an IF signal and experimenting
with different settings of filters for the best possible audio quality.
