Yes, the K3 will work for data modes using SSB. However, the DATA A
submode is preferred over SSB. The first advantage is that compression
is turned off, and the second is that the TX Equalization is turned off
too. If you have compression set for SSB and are using TX EQ, you will
need to remove those when operating in data modes in SSB. Data A
submode will do that for you, but yes, the default filter width is for
about 400 Hz. If you want a full bandwidth waterfall, it is as easy as
turning the WIDTH knob. A single knob adjustment is certainly easier
than going into the menu to set TX EQ flat on all ranges and then
adjusting the COMP knob.
But to each his own - I do not begrudge those who want to use data in
SSB mode, but since I operate both SSB and Data modes, it is easier for
me to use the K3 Data mode for data and SSB mode for SSB - I don't have
to change the settings once I set things up.

I use it all the time in SSB (USB) for data modes, especially for PSK31.
Most data mode software has built in filtering/DSP so the wider
bandwidth on receive works very well, for PSK31, and other data modes.
