[Elecraft] Re: K2 SSB Audio Problems

[Bob Baxter]

Ok, I'll try once more to get this past the spam police------

My audio problems have all been resolved, thanks to suggestions by Ron
AC7AC and Don W3FPR.  I did the 2nd filter mod and the matched crystal
mod and it made a day and night difference---should have done it years
ago.  I have a word recognition problem, due to ear trauma a few years
ago, and have shied away from ssb operation since.  I bought the MFJ
Speech Intelligibility Enhancer and while it made a big difference in
my Kenwood TS520S, it seemed to make the K2 worse.  This was the
sibilance effect that I mentioned in the first post.  As usual, I left
reading the DSP manual until everylthing else failed.  It told me that
the denoiser would affect speech quality so I turned it off and the
sibilance disappeared and I could understand most of what was coming
out of the speaker, even with the highs boosted.  It was a combination
of the denoiser and boosting the higher frequencies with the audio
unit that caused it.  I've been happy dancing until I'm plumb wore
out.
