Dave, which part of the instructions indicate your board needs the mod? The Elecraft Web site says K3's before: "about Oct 7, 2008, about S/N 1900"
The revision marked on your board has no bearing on this. Boards needing the mod will measure 604 ohms at R19 and R20 as Joe mentioned. 73, Barry N1EU DBellW6AQ wrote: > > I'm really confused.
