[Elecraft] Why I love the VFO shift bug

This is unbelievable.

I've had my K2 on the air since December 1999, and I NEVER experienced the
problem of the VFO sliding up the band by itself, so I never did the mod.  Not
until last night.

I was rag chewing with a VE3 on 20 meters when all of a sudden I heard a slight
choppiness in my keying...strange, and when I looked at the display I saw the
frequency incrementing itself.  So that's it, I thought, the dreaded VFO shift. 
OK, I'm not immune, time to do the mod.  I took the K2 to the bench, popped the
lid, took out the audio filter, the control board, and finally the front panel. 
Grumble, grumble.  Put in a jumper, put it back together, took it to the
operating table and hooked it up again.

I turned it on.  It was still on the frequency it had drifted to when I lost the
VE3, 14024.  There was a Greek station calling CQ, so I figured I'd answer him
and see if I'd screwed anything else up doing the mod.  Greek station? 
SV2ASP/A...Mount Athos...calling CQ in the clear!

Holy &*&*%$!  This is one of the rarest DX entities there is on CW!  YES!  I GOT
HIM!!!!!!!  I listened for quite a while as an enormous pileup built up.  All
evidence points to it being Monk Apollo himself, not a pirate.  It was one of
the most exciting experiences I've had in 46 years of ham radio.

Mojo?  Are you kidding?  The K2 tuned itself to his frequency for me!  Maybe I
should undo that mod.
