[Elecraft] K3 Filter question - SSB

[David Gilbert]

I also have a pair of the 1.5 KHz filters, and while I find them to be 
desirable under certain DXing situations, I rarely use them in a 
contest.  In a contest you need quick intelligibility and filters as 
narrow as 1.5 KHz don't necessarily give you that.  I have a pretty good 
ear, but lots of human voices have enough energy in different parts of 
the audio spectrum that I find it sometimes necessary to either shift to 
a wider filter or change the shift on the 1.5 KHz filter (I typically 
use 1.1 KHz for the center with that filter) in order to copy the other 
guy's callsign or exchange.  Plus, as W4ZV pointed out, there is so much 
atrocious splatter from crummy rigs or ignorantly adjusted rigs during a 
major contest that it is truly rare to find such a narrow filter 
actually being helpful.   I also would trade my 1.5 KHz filters for a 
pair of 1.8 KHz filters in a heartbeat.

73,
Dave   AB7E
