[Elecraft] K2 SSB problem--follow-up

Boy, is my face red.  For the benefit of those who helped with suggestions
concerning my SSB issue (power output pegging and out of control on PTT), I
must confess that when I began looking at this again (for the first time in
several years), I had completely forgotten that when I removed the SSB
adapter years ago, I put the two jumper wires and the C167 capacitor back
(as the instructions say to do).  But because I tacked them to the *bottom*
of the RF board, I didn't see them until last night, when I decided to
remove the bottom cover of the K2 case to nose around a bit on the RF board.

I've removed the jumpers and the cap, and the out-of-control power output
problem is gone.  I still don't know whether my SSB adapter is working
properly, because I don't actually have a real mic wired up yet (I've just
been using the dot key line as PTT)--I'll get a little electret element
wired up soon and give it a shot.

Thanks again to those who offered suggestions--even though I was barking up
the wrong tree because of my own oversight, I learned a lot along the way!

73, Doug (AA0MS)
