[Elecraft] K3 frequency accuracy versus displayed precision

Hi,

First time I have heard about this. How much frequency shift are we talking
about here? A fraction of a Hz, 10Hz? I have certainly never noticed this,
but of course on speech anything less than 10Hz is practically inaudible
unless you do a USB/LSB comparison on an AM station.
