Receiver bandwidth (BW) and passband
tuning (PBT) are adjustable using this
encoder.
DSP bandwidth and passband tuning are
selectable independently on each receiver

To adjust BW or PBT value: A green LED
indicator is next to the BW and PBT legends
on the front of the radio above the encoder.
Press the encoder to switch between BW
and PBT. The BW and PBT values are
shown per receiver on the screen. BW is
adjustable from 100 to 6000 Hz. PBT is
adju or – 2.5 kHz from center. PBT
can easily be cleared to zero. When the
PBT LED is lit next to the encoder, press the
encoder in and hold for two seconds. The
PBT value will revert to zero.
BW and PBT step size is adjustable in the
menu system in 10, 50, and 100 Hz steps
(10 Hz is the default setting). BW and PBT
can also be set to track each other
automatically on each receiver in the menu
system. See the description of
RX MENU

Chapter 3.

The MULTI knob is used for control of a
variety of transceiver values as assigned by
buttons pressed by the operator.

CUT control that modifies the BW function.
HI CUT and LO CUT (referred to

one edge of the filter
at a time towards
or away from the center of the passband.
