K3 Sub and Main Synchronization

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

Have you checked the 3rd decimal digit (Hz) by switching in FINE? I once had this and noticed that this digit which isn't normally displayed was different for MAIN and SUB....

Have you set the filter offsets to the same value?
