[Elecraft] Second call: K2 broken after KPA100 mod

[Steve Kallal]

I was hoping someone would answer me on this one. The phone lines at
Elecraft don't open until I am at work.

I am about done with part 1 of the assembly of the KPA100 option. I opened
the K2 and removed pin 4 from P4 on the control board per the instructions.
Rather than connect the partially assembled KPA100 to the K2, I powered up
the K2 first. Now the K2 doesn't initialize.

Apparently my K2 is not completely broken. With the antenna hooked up, the
receiver is definitely alive. It appears that the control board isn't
functioning. The display stops ELECrAFt and doesn't go further. The tuning
knob has no function. The S meter doesn't move. But sometimes signals are
heard. I DON'T hear the 4 MHz clock in another receiver per the K2
troubleshooting section.

I did the firmware reset hoping that might fix it. It didn't. I did have the
CAL FIL BFO settings saved in a spreadsheet. But I didn't have any CAL PLL
settings written down. Once the K2 is back, I'll have to learn that
procedure since this is a used K2.

One definite repeatable symptom, is that the power has to be toggled on
TWICE, before anything is displayed on the LCD.

Please I hope for some assistance here. It is probably a loose connection,
but everything seems solid.

I will be emailing Elecraft support also.
