CAL PLL on K2 gives bizarre result

[Tony Estep]

I went through the dial calibration process with my K2 as outlined on Don's
(W3FPR) web page. After adjusting C22 as called for, I ran CAL PLL. When it
finished, the radio was in a frozen state from which I can't recover it. The
only band that works is 30M, which seems normal. All the others can't
receive or transmit. The S-Meter periodically flashes full-scale, and
occasionally static crackles come from the speaker. The menu items are
accessible and the filter and BFO settings seem intact. The radio was
working normally when I started CAL PLL, and went into this state during the
time CAL PLL was running. I was in the room with it typing on my computer,
but not touching it. What happened?? Anybody have any idea??

  Tony,

I have never seen anything like that happen during CAL PLL, so all I can
do is venture a guess --

Check the frequency of the VFO - and check the secondary menu D19
setting.  "D19 = y" if you have the K60XV installed (or the rework
eliminator equivalent for that option), otherwise the D19 parameter must
be set to "n".

If this menu is set wrong, you will "apparently" hear things on 30
meters, but do not transmit - you will be transmitting outside the ham band.

If D19 was set incorrectly during your CAL PLL run, you will have to run
CAL PLL again to get the EEPROM contents correct.

It could also be that something failed in the VFO circuit during the CAL
PLL process, but that seems too coincidental to consider for the first
pass analysis,
