Jim, It is better to use the approximate ship date posted on the Elecraft website listing of K3 Mods and Enhancements. There can be a serial number differences between the factory ship K3s and the kit versions - the factory built K3 are at the factory longer after the serial number has been assigned, so the ship date is a better reference.
OTOH, it is a simple matter to remove the top cover and look at the board. 73, Don W3FPR Jim Miller KG0KP wrote: > Does somebody have an approximate serial number when the erferenced "Rev B" > KIO3 bd began to be used? > > Thanks es 73, de Jim KG0KP > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
