[Elecraft] Problem: K2 Audio Tuning Click or Warble

[Bill Johnson]

I have units listed below and the # 35 SN with most all upgrades does not
have the problem.  Buying a new one and building it will not resolve the
issue with the old.  The techs on this list can help you or you can send it
in for a complete checkup and fix if you are ready to through in the towel.

Hi Bill,

You're not completely alone!  Mine does that to a much, much lesser degree.
Noticeable as a slight warble as one tunes through a signal slowly.

My s/n is 1434 with most if not all upgrades. Firmware is current.

I'm planning to buy a new K2 in the next day or so -- one of the reasons is
to see if the problem is gone!

Anyone posting responses to Bill's questions, please be sure they are posted
here too.

Thanks,

Bob W1XT
