My computer software has a choice of waterfall bandwidth, 2K
(from 400Hz to 2400Hz) or 4K (400Hz to 4400Hz). In both Data A
and SSB I can adjust the DSP bandwidth up to 4200Hz on the high
end which gives me most of the bandwidth of the 4K setting. Note
that you will need a wider crystal filter than the 2.7KHz
default to get the wider DSP bandwidths.
Most of the time I narrow the DSP bandwidth down to 100 to 250Hz
for QSOs. It keeps strong stations from overloading my computer
software input.
Don and Joe have described the advantages of Data A over SSB for data.

K3 does not have to be in Data mode to work with the Signalink.
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.
