10.1.2 CW Continuous Wave
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:
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:
400 … 1000 Hz
Increments: 50 Hz (DSP on and off)
Width Select filter bandwidth to following values:
DSP on: 50 / 100 / 200 / 400 / 500 Hz
DSP off: 500 Hz (fixed) ( / 250 Hz with optional hardware
extension *)
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:
–250 Hz ... +250 Hz
Increments: 10 Hz (DSP on and off)
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.
