q PASSBAND TUNING CONTROLS [TWIN PBT]
Adjust the receiver’s DSP filter passband width.
(p. 46)
• The limit of the variable range depends on the pass-
band width and 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 models) steps.
• Rotate both [TWIN PBT] controls (PBT1 and PBT2) to
the same position shifts the IF.
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.
