[Elecraft] K3 VFO A encoder noise

[David Moes]

Is this normal?
I'm getting a strange noise when turning the VFO A   on 10m  at around 
28.000 to 28.007  then again at 28.037 to 28.045     as I turn the VFO I 
get a buzz or rattle from the speaker or in the headphones.    hard to 
describe but much like the sound of a needle scratching across a 
record.      if I rock the VFO back and forth its like scratching the 
needle back and forth across the record grooves.  when I turn it slowly 
it makes one click per VFO step.   if I set it to fine its a click per 
1hz step   then normal its a click per 10hzstep and so on.    its not 
loud and registers about s2  on the meter.  with no antenna attached  
and is barely noticeable with an antenna as its almost below the noise 
at least here in the city.   I havent noticed it elsewhere or on other 
bands.
