My Faithful K2/100 has died!

[Bruce McLaughlin]

My K2/100 appears to have died in a manner of speaking.  It was working
perfectly up until recently.  Last weekend I decided to use it. When I
turned it on, the display showed the Elecraft test and then 7.167 L.
That was it!  There is no response to any of the buttons.  The frequency
cannot be changed.  There is no bar graph display and no signals.  It
does communicate with the computer in the sense that the VFO frequency
is displayed in my Log EQ program.  But that is it.

 

Preliminary reference to the trouble shooting guide suggests there may
be a problem involving U6 the big chip on the control board.  But I'm
not at all sure where to begin.  Someone suggested I might try a reset
first.

 

I sure would appreciate any suggestions as to how to start tracking down
the problem.  The unit has a serial number of just over 3000.  It has
been only lightly used and has not been abused.  So what happened is a
mystery to me.

 

Thanks for any help and suggestions.

Bruce,

That is a result you would observe if the K2 were locked in transmit.  Check
to see if you have a problem with the PTT input or the paddle DOT input
first.  If you don't find anything obvious, let us know and we can likely
provide some other checks (but you will have to do some measurements for us.
