K2 INFO 232 error with PLL

On a K2, the freq display is way, way off; e.g., on 40 meters it's really
receiving about 0.5 mHz lower. I tried to run CAL PLL but get INFO 232.
The PLL process appears to start, momentarily displaying 11,27164 mHZ,
then aborts in about a second with the INFO 232 error. I'm absolutely
positive before running PLL that the VFO shows a 40 meter freq and the
probe is plugged into TP1.

The CAL FCTR readings for the TPs are: TP1 = 11271.8(4); TP2 = 4913.55;
TP3 = 12097.9(6) (Numbers in parentheses flicker between an adjacent
digit, but values are otherwise stable).

Probably not relevant, but more background. This is my friends K2 for
which the KPA100 would not work. I traced problem to blown diode in swr
bridge, fixed it, and that problem was solved. Also, I Initially I made a
change in the set-up menu for the k60xv, not realizing it was installed.
Nothing else was touched--at least intentionally.

Ideas where I can start? I do have my own working K2 for comparison
purposes. Dick, K0KK

Re: K2 INFO 232 error with PLL

Dick,

With the K60XV installed, do your have the menu for d10 set to "Y" - i
needs to be that way or CAL PLL will fail as you stated.
The initial frequency for CAL PLL is in the 12,960 to 12.990 range.

Your TP1 reading also says that the frequency the K2 is trying to tune
to is near 6350 kHz - again the problem is the d19 menu parameter.

73,

Re: K2 INFO 232 error with PLL

Don, I changed the setting to "Y," and it instantly jumped back on
frequency and everything is fine again. As always, I really appreciate
your expert and responsive help.
