[Elecraft] K3: Peculiar BW behavior?

[Walter V. Gilles]

Thanks to all who responded.  The problem appears to be solved now.

I used the utility to check things out before making any changes, and all
was as it should be.  However I reloaded the current release firmware, and
increased the insertion loss compensation on the 0.40 roofing filter from
1db to 2db.  I don’t use any other compensation.  Upon checking on air, the
freq shift and fadeout experienced previously on 20M at 0.20 BW is gone, and
a quick check on a few other bands indicates that problem is fixed.  Now on
to that “clicking” noise.

The clicking seems a bit reduced, or I think it is anyway, which is really
all that matters.  I have heard that the human brain is the best filter one
can have, and I believe that clicking noise has always been there, as
suggested by some of the responses (posted & e-mailed).  I believe I (my
brain) was discriminating (selectively filtering) the non-information (QRM,
band noise, crashes, pops etc.) from the information (CW note) before.  Then
when I was just mentally idling, working with the controls (NB, NR, BW,
etc.) to get familiar with specific settings for different band conditions,
I probably shifted attention away from the CW note and onto the background –
hence discovered that “hidden” clicking.  Anyway, the K3 appears to be a
happy camper again, and I learned a few things in the process.  Thanks.  73
