[Elecraft] K3 in WPX SSB with 2.7 roofer

[Fred Jensen]

That's been my experience too, Dave.  SSB is not my forte ... severely 
compromised hearing ... but I do get into a small handful of phone 
contests [not WPX SSB, for the reasons you mentioned].  I had a borrowed 
1.8 filter for awhile, and found that it really did degrade the audio. 
Conversely, I've never had a problem with strong adjacent signals using 
the 2.7 even though I've got a couple of close neighbor hams.
