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.
