4 RECEIVE AND TRANSMIT ■ 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 passband widths are available. For FM mode, 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 memorized in each filter.
