This transceiver has 2 built-in IF filters: A and
B. The IF Filter settings are stored with the last
settings of the LO/WIDTH and HI/SHIFT controls.

and B.

Kenwood digital signal processing (DSP) technology
is adapted to this transceiver. Using DSP filtering
(AF), you can control the bandwidth, cancel the
multiple jamming beat, and reduce the noise level.

For improving interference reduction capability, this
transceiver also provides IF filters designed using
DSP technology. When in SSB, FM, or AM mode, you
can change the filter bandwidth by altering its low and/
or high cut-off frequency. For CW, FSK, and DATA
modes, you can change the filter bandwidth by directly
specifying a bandwidth. Changing the filter bandwidth
does not affect the current receive frequency.
• The meter display changes, based on the
bandwidth you are setting up.
