K2 issue or is it?

[barry halterman]

Greetings folks. My K2 has a snapping sound when tuning the band regardless
of mode and it seems to happen when I am close to a signal...within 4 khz
or so. The snapping sound can be very strong sending the s meter soaring.
Not only does the s meter go soaring, so do my ears!
At this point I am not sure if this is more or less the nature of the
beast....
Don't remember reading anything in the reviews about this oddity.

Barry, can you provide more detail about the K2 settings when you hear the
snapping sounds?
 
For example, does this effect occur only in CW mode, or in USB and LSB modes
as well?

For which filter settings does it occur (both CW and SSB filter settings)?

Is your AGC turned ON or OFF?

Does the snapping subside if the RF (actually IF) gain is backed off?

Does the snapping subside if the AF gain is backed off?

Does this phenomenon occur on all bands or just a few bands?

Don, W3FPR, will likely have a few possible causes immediately in mind after
repairing hundreds of K2 radios over the years!

73,
Mike, K8CN

Barry,

That can happen if you ran CAL PLL with the bottom cover off.  Try it again.
