RECEIVING AND TRANSMITTING
The IF Shift function electronically narrows the
passband frequency of the intermediate frequency (IF)
and cuts out higher or lower frequency components of
the IF to reject interference.
The function shifts the IF frequency up to ±1.2 kHz in
the SSB/CW/RTTY modes and up to ±250 Hz in the
CW-narrow/RTTY narrow modes.
The IF shift is not selectable in the AM mode.
IF shift operation example:
• Adjust the [SHIFT] control for minimum
interference.
• When IF shift is used, the audio tone may change.
• Set the IF shift control to the center position when
there is no interference.
