Barry is correct. The Revision number printed on the board is for the PC Board layout itself, and has little relationship to the version of the populated board. This is not an "Elecraft only" situation, it is common in the industry. This is quite common with computer option cards as well, especially video cards.
Now, if there is a paper sticker on the board, it will usually convey the level of the assembled board. Bottom line - do not depend on the markings on the board for level identification without further manufacturer's substantiation that the markings on the board do indeed identify the level. 73, Don W3FPR On 1/19/2011 8:39 PM, Barry N1EU wrote: > 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.
