The filter selection is automatically memorized in
each mode.
The PBT shift frequencies are automatically memo-
rized in each filter.
•Duringthepassbandwidthsetting
■ IF filter selection
The transceiver has 3 passband width IF filters for
each mode.
For SSB, CW and PSK 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 mode, the passband width can be set within
200 Hz to 10 kHz in 200 Hz steps. A total of 50 pass-
band widths are available.
For FM mode,thepassbandwidth is fixed and3
passband widths are available.
