David, I will reply anyway, because a situation like that is of extreme interest to me.
That is a a real mystery. I did the pilot build on the new KSB2 board and encountered no problems with those diodes. Something may have changed since I did that build, and the only two things I can think of are that the 1N4007 leads got thicker or the holes got smaller at the board manufacturing house. The board I worked with was *not* pre-production since Wayne was quite anxious to get this new board into production, he took the risk of cutting the new board in before I received my field test kit. The normal holes for the 1N4007 diodes are the same size as for resistors and other components even though the 1N4007 leads are larger, they will fit in most any hole designed for resistors - that is true for all the K2 boards that I know about. Do you have other unassembled options for the K2? If so, try the 1N4007 leads in a hole intended for a resistor on any of your other boards. 73, Don W3FPR On 7/24/2011 9:02 PM, David Dietrich wrote: > Hi All! > > I already E-mailed Wayne about this, but I thought I would share this with > the rest of the group in case anyone got one of these recently and hasn't > assembled it yet.
