Re: [Elecraft] erratic vfo
Frustrating for sure! Does Elecraft support have any suggestions?

Re: [Elecraft] erratic vfo
Hi Chris How old is your K3 ? I built mine in 2008 (s/n 1397). It has all the "works" and I have recently upgraded it with all the new boards available. I have never experienced what you are suffering and I am running all of the latest firmware and a KPod.
