[Elecraft] K3 VFO episode

[Gary Hinson]

Hi guys.

This morning while calling some DX - split - on 30m, it sounded as if the DX
suddenly drifted about 100Hz LF.  I thought at first I had knocked my VFO
but no, the frequency on the display was the same.  However, having
accidentally QRMd the DX (oops!) I noticed that the K3 had fallen out of
split.  I suspect the cause was some sort of control glitch with the K3 but
operator error is of course a distinct possibility, it being just after dawn
and just before my first cup of tea here.

Any ideas what might cause this?  Has anyone else experienced it?

I'm running firmware 4.25.
