VFO drift KX3

[Jr]

Lately, I've noticed my 3-year-old KX3 drifts a small amount, according to
the readout, in CW mode. For instance, if I set rig on 7.033.00 hit the key
and look at the readout it will say 7.033.010 and sometimes bounces back to
7.033.00

I don't remember this being a problem before. Is this normal for the KX3 or
is there something I should look into?

Thanks and 73

I suspect it is the VFO button itself.  If it is too loose, a tuning step can be generated
one way or the other.

My KX3 also drifts as well, I mostly use it on digital modes. Can’t remember when I bought it but it was over 3 years ago.
