[Elecraft] K3: KFL3C-200 filter

[Barry Simpson]

I installed two of the new 200Hz filters in my K3 main and sub receivers a
few months ago as part of a major upgrade. Previously my narrowest filters
were the 400Hz.

I am very happy with the 200Hz filters and find them very good in contests
and pile up situations (when on the receiving end).

I generally operate split in such situations and transmit on VFO B and
receive on VFO A so that I can tune around the transmit frequency and pick
out stations with the very narrow filter.
