[Elecraft] K2 VFO Linearization Problem

[rrkrr]

K2 #3766, a kit that I bought a few years ago and let sit on the shelf 
for a while.  I'm finally threatening to finish it.  All has gone well 
up to the VFO Linearization step in Alignment where the CAL PLL menu 
item is supposed to be run.  I've followed the instructions to the 
letter, but when I go through the menu, select CAL PLL and hold the 
"EDIT" key to start the linearization sequence.... nothing.  The 12099 
kHz frequency is displayed, but does not change.  There are no "d"s 
displayed to indicate stored data points.  Nothing happens.  Any ideas?

MCM firmware is 2.03.  IOC firmware is 1.07
