[Elecraft] K3: Filter choice 2.7 or 2.8 kHz - effect on transmit audio

[Barry N1EU]

I expect any such comparison to be premature.  The main limitation on
"fuller" audio is not being able to vary the transmit passband and I believe
that feature will be added in a future firmware enhancement.

The main advantage of the 2.8 filter is probably better immunity to
interference by very strong signals that are just outside of the passband
due to its steeper slopes than the 2.7Khz filter.
