[Elecraft] K3s Odd sound vibrations Edit - Hypothesis, Steps, Conclusion, and Request.

[Jerry Moore]

I had someone contact me off list to suggest putting some small bits of tape
where the cover touches the center stiffener. I did that and now have zero
buzzing except around 440HZ or when monitor is turned up nearly all the way.


I'm not sure why this isn't an advertised fix. Tape/silicon the ferrite
beads on both boards and install x5 30mm strips of black tape in specific
places.
Easy fix. 
I've heard it said that nobody remembers what you said, only how you made
them feel. Right now I'm not feeling too warm and fuzzy about my radio manf.

Thanks to all who contacted me off list with suggestions and shared
frustration for this issue.

No, I have not done this mod.  But I have just added it to the list, because
I AM using the internal speaker.  External speakers are on the list, but
some way down, so I will be using the internal speaker (or actually phones)
for some time.

In all fairness, I would think this issue is only rarely an "issue" for the
VAST majority of ops...  Between external speakers, not having the PA to
begin with, or using headset/phones, most folks probably don't use the
internal speaker at audio levels sufficient to reproduce the issue.

I would prefer to do the fix myself than to have the additional labor
involved in fixing the beads/conductors down (and the accompanying increase
in price/avail of PA modules).

I examined my K3s closely as I assembled it... I consider it a supremely
well-engineered piece of equipment and worth every penny I paid.  :-)

Have a super day!
