[Elecraft] [K3] Elecraft roofing filters

[Doug Faunt N6TQS +1-510-655-8604]

The 250Hz and 400Hz filters are very similar, in reality.  Having both
is redundant.  But having a 1.8kHz or 2.1kHz for SSB RX is a good
thing for contesting.  Note that some people have used a custom 1.5kHz
roofing filter with good success for SSB contesting.

This is all from a little experience, and listening to people with
LOTS of experince and knowledge.

   I agree with that, but the 1.8kHz sure helps in SSB Contests
