As I see it, some benefits of a 750 Hz width filter are that ...

o   It's about the optimal width if you are only getting one CW filter for
    general (i.e. non-contest) use.

o   For all but the most serious CW contesters, it would make a perfect
    one/two combination along with either the INRAD 400 or 250 Hz filter.

o   In most applications it can replace both the 1 kHz and the 500 Hz 8-pole
    filters, thus freeing an existing slot or saving on an initial purchase.

Please email webmaster at unpcbs.com to express your interest in purchasing a
750 Hz 8-pole INRAD roofing filter for your K3.  If there is sufficient
demand, then we will special order them in batches of ten, and offer them
at $125 plus our standard shipping and handling charges.  We do not intend
to stock these filters, although if demand turns out to be "astronomical"
then we would certainly reconsider.
