!7 PASSBAND TUNING CONTROLS [TWIN PBT]
Adjust the receiver's DSP filter passband width.
• The limit of the variable range depends on the passband
width and operating mode. The limit of the variable range
is half of the passband width, and PBT is adjustable in
200 Hz (AM) or 50 Hz (other modes) steps.
• Rotating both [TWIN PBT] controls (PBT1 and PBT2) to
the same position shifts the IF higher or lower.
4 What is the PBT control?
Generally, the PBT electronically narrows the IF
passband width to reject interference. This trans-
ceiver uses the DSP circuit for the PBT function.

The Manual Notch Filter is an adjustable narrow
