[Elecraft] K3 Sub and Main Synchronization

[Tom, N5GE]

Today when I turned on my K3 #806 I noticed that when the sub and main
vfos were both on the same frequency they sub and main receivers were
not quite on the same frequency.  I would guess by the wavering that
they are probably 2 to 5 hz off per second.  The wavering is heard in
the band noise on 6m.

Is there an adjustment I can make to get them dead on.  It's not the
first time I've noticed this.

Thanks,

Tom, N5GE
