K2 vfo linearization

Scott McDowell-4
Hi
I'm trying to do the vfo linearization on my k2 and am having a problem
again!
Every time I do the cal pll I get the frequency on the counter of 11959.64
for an instant, then the info 232 message about not being on
40 meters. It never goes beyond the info msg. I have entered the frequency
 with the key pad and changed the band with band + and band _  and I still
get the same  message. I also checked the frequency
with another transceiver and it is receiving on 40 meters.
Anyone have any idea why this is occuring?
Thanks
Scott N5SM

Scott,
   
  Make sure you are tuned between 7.0 and 7.1 Mhz and you are on the right test point (TP1). It's been a long time since I aligned my K2 but I vaguely remember making that mistake and getting the same error.

Scott,

The K2 looks for a frequency reading near 12,100 kHz when it starts the
CAL PLL sequence.
If yours is only going up to 11,959.64 kHz, that is not high enough.  
Info 232 is a usual result if the initial frequency is too low.
Check your PLL reference oscillator range again (check at TP3).  If it
is not as high as it should be, then that alone is the problem to be solved.

What is the frequency read by CAL FCTR when tuned to 7000.00 and the
probe inserted into TP1?  It should be quite near 11,915 kHz.

73,
Don W3FPR
