[Elecraft] No output - internal spkr - K2/100

[Don Wilhelm]

This seems to be a common problem - but I have never experienced it myself.
Unfortunately the form factor for that headphone jack seems to only have one
manufacturer.  One can say 'bad design decision' or 'faulty parts' or
anything else, but that does not solve the problem - it would appear to me
that the jack manufacturer has a quality problem, and it won't go away until
that is solved.

There is a work-around that would be 'acceptable' to me, but may not be for
everyone - and that is to short across the contacts of the headphone jack
with a jumper and leave the speaker active all the time - if you want to use
the headphones without the speaker, just stick an empty 3.5 mm plug into the
external speaker jack to silence the internal speaker.  I know it is not
nice, but it will work.

73,
