IF filter selection
[
The receiver has 2 to 4 passband width IF filters for each
mode. Selectable passband width are from 3, 6, 15, 50 and
230 (depending on the selected mode).

230 (depending on the selected mode).
• Selectable passband width for each mode.
SSB mode : 3 (2.8 kHz) or 6 kHz
CW mode : 3 (2.8 kHz) or 6 kHz
AM mode : 3 (2.8 kHz), 6 kHz, 15 kHz or 50 kHz

IF shift function
[
The IF shift function electronically changes the passband fre-
quency of the IF (Intermediate frequency) and cuts out higher
or lower frequency components of the IF to reject interfer-
ence. This function is available when the receive mode is se-
lected SSB or CW mode, and shifts the IF frequency up to
±25 steps in 1 step (50 Hz).
