5 FUNCTIONS FOR RECEIVE ■ IF filter selection The transceiver has 3 passband IF filter widths for each mode. For SSB and CW modes, the passband width can be set from 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 from 50 to 2700 Hz in 50 or 100 Hz steps. A total of 32 passband widths are available. D IF filter selection q Push MODE several times to select the desired mode. w Push FILTER several times to select the IF filter from Wide, Middle or Narrow. • The selected IF filter indicator (" ", " " or " ") appears in the LCD. For AM mode, the passband width can be set from 200 to 8000 Hz in 200 Hz steps. A total of 40 passband widths are available. The filter selection is automatically memorized in each mode.
