[Elecraft] K2 VFO Linearization fails

[Don Wilhelm]

Bob,

Have you first checked the PLL range?  With the probe in TP3 (you may 
have to remove the KDSP2 or KAFT2), and menu in CAL FCTR - what is the 
frequency when you tap the BAND+ button?  What frequency when you tap 
the BAND- button?

If you have a good PLL range, then the frequency should decrement during 
CAL PLL.  You say it does not, and I believe that, but start with the 
PLL range frequencies and then we can hone in on the problem spot.
