CW pitch control

The received CW audio pitch and monitored CW
audio can be adjusted to suit your preferences (300
to 900 Hz) without changing the operating frequency.

The received CW audio pitch can be adjusted in 25
Hz steps.

The filter set mode screen graphically displays the

CW pitch operations. (See below.)

IF filter selection

The transceiver has 3 passband width IF filters for
each mode.

For SSB and CW modes, the passband width can be
set within 50 to 3600 Hz in 50 or 100 Hz steps. A total
of 41 passband widths are available.

For RTTY mode, the passband width can be set
within 50 to 2700 Hz in 50 or 100 Hz steps. A total of
32 passband widths are available.

For AM and FM modes, the passband width is fixed
and 3 passband widths are available.

The filter selection is automatically memorized in

each mode.

The PBT shift frequencies are automatically mem-

orized in each filter.
