during CW operations

Listed below are the filter bandwidths (unit: Hz) that can be chosen; default values are shown in bold.

CW
WIDTH	50	80	100	200	300	400	500	600	1000	2000

FSK
WIDTH	250	500	1000	1500

When the optional CW filters are installed, the TS-480 will automatically select the optimum IF filter in accordance with the DSP filter bandwidth.

Also available are filters for PSK31 and RTTY data mode operations. From the menu, if you select ON for the “Available data communications filters”, these data communications filters can be used in SSB mode. You can choose from 3 center frequencies and 7 WIDTH settings.

Listed below are the filter types (unit: Hz) that can be chosen; default values are shown in bold.

For data
communications
Center	1000	1500	2210
WIDTH	50	100	250	500	1000	1500	2400

During PSK31 operations, the center frequency is set to either 1000Hz or 1500Hz.

Furthermore, since it is now possible to select an optional CW IF filter in SSB mode, it is possible to narrow the bandwidth.
