[Elecraft] Data Filter for K3

That depends on the data mode and your operating style (FSK vs.
AFSK or click on the waterfall vs. tune the signal).

For traditional FSK RTTY the best overall choice among currently
available filters is the INRAD/Electraft "250 Hz, 8-pole" filter.
The second choice is probably the INRAD/Elecraft "400 Hz, 8-pole"
filter.  The two filters are two close in performance to justify
both in the same rig and the "250 Hz" filter is too narrow for
general (non-contest) CW operation so the edge probably goes to
the "400 Hz, 8-pole" filter unless you're a RTTY contest op.

If you're an AFSK/PSK "click in the waterfall" type operator,
either the 2.7 or 2.8 KHz filter will give you plenty of room
to click.
