4 To return the display to the current operating
mode, press [DISP].
Note:
The cut-off frequencies can be adjusted independently for
each operating mode. When you change the operating
mode, the previous setting is recalled for each operating
mode.
When the Packet filter (Menu No. 50A) is ON, you cannot
change the DSP filter bandwidth. Switch the Packet filter
OFF to adjust the DSP filter bandwidth.
CW/ FSK Modes
1 Press [CW/ FSK/ REV] to select CW or FSK
mode.
2 Press [DISP].
The current filter selection appears.
3 Turn the LO/ WIDTH control clockwise to
increase (wide) the bandwidth, or
counterclockwise to decrease (narrow) the
bandwidth.

4 As for CW, you can further adjust the shift
frequency for passband. Turn the HI/ SHIFT
control to adjust the shift frequency from 400 to
1000 Hz in steps of 50 Hz. The default shift
frequency is 800 Hz.
5 To return the display to the current operating
mode, press [DISP].
DSP FILTERS
KENWOOD digital signal processing (DSP)
technology is used for the functions described in this
section. Using DSP filtering, the TS-2000 frees you
from installing many analog filters for each operating
mode. Additionally, you can control the bandwidth,
cancel the multiple jamming beat, and reduce the
noise level using DSP filtering technology.
CHANGING THE RECEIVE FILTER BANDWIDTH
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 and FSK
modes, you can change the filter bandwidth by
directly specifying a bandwidth. Changing the filter
bandwidth does not affect the current receive
frequency.
Note:
The receive filter bandwidth can be changed only on the main
transceiver.
The IF DSP filter is not available in FM mode.
SSB/ FM/ AM Modes
1 Select SSB, FM, or AM mode.
2 Press [DISP].
The current filter selection appears.
3 Turn the LO/ WIDTH control clockwise to raise
the low cut-off frequency, or counterclockwise
to lower the low cut-off frequency.
