SHIFTWIDTH Knobs (EXCEPT ON FM MODE)

SHIFT Knob

The inner [SHIFT] knob provides adjustment of the IF DSP passband, using 20 Hz steps for precise adjustment 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.

ADVICE:

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

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-clockwise 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.

ADVICE:

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.
