I'm about to launch into building KX1 #1541 which I've had for a while. My
manual is Rev B; I see Rev C is current. I've searched the Elecraft Web site and can't find a list of changes between versions of the manual, nor can I find any notes about any modifications that might be needed to bring an older kit up to the latest specs. I found "Builder's Alert #1" from April 10, 2006. This particular alert is incorporated into the errata sheets in my KXB3080. What I'm curious about is what other changes prompted the update from Rev B to Rev C? I'd like to be completely up-to-date when I'm done.

Craig,
I work on many KX1s and can say with certainty that the manual changes are minor - there has been little change in the KX1 circuits over its lifetime (other than the changes for the KXB3080 option). One change is the number of turns on L3. If your manual says 6 turns, increase that to 18 turns. This change was necessary for the addition of 80 meters with the KXB3080. There are no mods to the KX1 other than the addition of the Power Output Mod should your KX1 not develop 3.5 watts or more on 20 meters with a 13.8 volt power supply. Do *not* install this mod if your KX1 has adequate power output - the PA output components can be stressed with powers much over 4 watts. Other changes are mostly for clarification and wording. For one thing, the use of body color to identify inductors is no longer being used because suppliers can change the color at will with no electrical difference (the colored marking bands are important ans will not change). 73, Don W3FPR Craig Rairdin wrote: > I'm about to launch into building KX1 #1541 which I've had for a while.
