Pass Band Shift

The JRC NRD-545 Passband Shift allows you to change the center frequency of the IF filter (± 2.3 kHz , in 50 Hz steps) with no apparent change in the reception frequency. PBS acts to set the offensive adjacent signal out of the receiver's passband. As the PBS knob is rotated, the degree of change is displayed on the LCD.

In the USB mode, disturbance signals can be removed from the higher of the voice signals when this control is turned counterclockwise from the center position. Note that the high area of the desired signal will be cut off at this time. In the LSB mode, the reverse is true. PBS does not work in these modes: FM, FM-Wide or AM-Sync.
