[Elecraft] "AF" pad? KPA100

[David Wilburn]

Page 21 of the KPA100 document (version D).  In the initial tests, right 
column, second row from the bottom of the table;

"AF" pad (measure from bottom), ground   > 10k

What is the "AF" pad?  I assume I am supposed to measure it from the 
bottom of the board, to ground, and it is to be greater than 10k.  But I 
can't sort out what "AF" pad is.  I even checked the version E document. 
  So it is probably something obvious that I am just not getting.
