[Elecraft] KPAIO3 modification - E740287

[G4GNX]

Hi Ron.

Thanks for the confirmation. I figured out that Rev A was a mistake, after 
looking at the fan connector and fan supply orientation. Had Rev A been used 
it wouldn't have been a disaster, but the mod would have had no effect, as 
it connected both ends of the capacitor to the positive fan supply! Oops! I 
haven't seen any errata but it doesn't matter now.

My KPAIO3 module isn't the same layout as the ones shown, but the actual 
connections are the same to the fans.

Well, I completed all of the mods, so now to put it all back together. <g>

73,

Alan. G4GNX

Hi Alan:

Use Rev B. Rev A of the instructions had an error that was corrected by an
errata. Apparently you don't have that errata. The change was subsequently
included in the Rev B printing.
