10.1.2 CW Continuous Wave

Fig. 27a
In CW (resp. CW–) mode the parameters Pitch, Width und BFO as well as
their specific value can be selected by using the knob WIDTH/SHIFT.
Pushing WIDTH/SHIFT knob will cycle between the parameters:
 Pitch  Width  BFO 
The chosen parameter and its current value are displayed left of status field in
combination with a small graphic:
BFO Frequency
Value
Turning WIDTH/SHIFT knob will allow the following:
Pitch Varying the distance of the BFO frequency against the transceiver
operation frequency (and against the filter center frequency;
transceiver operation frequency and filter are linked).
The tone pitch of the received signal is changing.
Tuning range:
Increments:
Width Select filter bandwidth to following values:
DSP on:
DSP off:
BFO Shifting the filter (filter center frequency) against BFO frequency and
transceiver operation frequency (BFO frequency and transceiver
operation frequency are linked).
The tone pitch of the received signal does not change.
Tuning range:
Increments:
After power on the BFO offset is set to zero (default value).
The frequency of the monitoring TX signal (800 Hz ; volume adjustable by the
Monitor control, see page 70 ; 20.7 ; Fig. 109), is not influenced by the Pitch
value.
