[Elecraft] K3 Erratic VFO behaviour, Switching bands and freq's

[G Wood]

Hello Pete

A few months ago I had similar problem with my K3 (sn: 05845).

I upgraded the FW from 05.29 to 05.38, tuning the vfo, the freq would jump, 
sometimes out of band. One occasion both vfo's read 300.000.00.

The rig had worked fine on the old FW so I reverted back to FW 05.29. That solved all the problems, that was 7 months ago, touch wood everything has worked fine since.

Something worth trying before taking boards out etc.
