It turns out that the 82 pF cap I was looking for in the BFOMDKT kit is actually in the K2ATOBKT kit.
In addition to some parts consolidation, the Upgrading the Elecraft K2 to Revision B (K2ATOBKT) instructions seem to over-ride or modify some of the instructions in the earlier upgrade kits. Mostly in the area of the sequence of alignment. I will go through all the instructions now to get them synchronized. :-) Thanks, Doug W0UHU — > > Doug, > > I have doubts that the toroid for L33 has been changed. > > C174 should be 82pF - call support to get a proper capacitor. > Do not remove turns from L33. > > The BFO should come into range with those values.
