[Elecraft] K3 Stops Transmitting

[Dennis]

I did try the "drop" test- hold up the front of the radio a little bit, 
and then drop it so that it contacts the table.
Kinda shake things up a bit.  No luck.  When I also brought it home, I 
put it in the case, drove it 72 miles
back to my house, brought it in, and set it up 2 days later.  So it was 
jostled fairly good.  As I say, when I got
it home it worked, and has worked, fine.

It went into transmit, just no RF. I tried power cycling, jiggling external connectors, etc. After about 10 minutes, and about one minute before giving up for the contest, while moving things around I unintentionally snapped the front bail, and things snapped back to life.
