[Elecraft] [K2] wobbly VFO knob, other knob "issues"

[John Shadle]

My K2 is very low use (just finished it a few weeks ago). When I turn
the main VFO knob it wobbles a *lot*. It seems like it especially
wobbles vertically, but also other directions as well.

I tightened the screws (which were already tight, by the way) and that
didn't help at all.

Any ideas?

Also, it seems like sometimes when I turn the knob a certain way for a
long time (e.g., counterclockwise) it starts to get really "tight" and
I have to turn it clockwise for it to ease up. Maybe I like to scan
down a lot--but this seems kinda odd for the knob to get tight like
this.

Thanks!
