[Elecraft] 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??
