SHIFT Knob
The inner [SHIFT] knob provides adjustment of the
IF DSP passband, using 20 Hz steps for precise ad-
justment and easy reduction of interference on either
side of your operating frequency. The total adjustment
range is ±1 kHz. The normal operating setting for this
knob is straight up, in the 12 o’clock position.

You may shift the Sub band (VFO-B) filter passband
via Menu item “042 S-iF LSB SET” through “049 S-

WIDTH Knob
The outer [WIDTH] knob sets the overall bandwidth
of the IF DSP filter for the Main (VFO-A) receiver.
The center (12 o’clock) position establishes the “de-
fault” bandwidth (for example, 2.4 kHz for SSB);
clockwise rotation of this knob increases the bandwidth
(out to a maximum of 4 kHz), while counter-clock-
wise rotation reduces the bandwidth.
When the NAR (Narrow) filter selection is engaged,
the [WIDTH] knob is disabled.
The [SHIFT] knob may be used to re-center the pass-
band response on the incoming signal, and you may
find that the CONTOUR and IF Notch Filter may also
help improve intelligibility and/or reduce interference.
See also the discussions of the [CONTOUR] knob and
[NOTCH] knob.

When the [NAR] button has been pushed, the [WIDTH]
knob no longer functions (except the CW mode). The
IF SHIFT system is still fully operational, however.
