[Elecraft] K2 stoppages

[W3FPR - Don Wilhelm]

Ben,

I can't venture a guess for your exact problem area other than it is
somewhere in the transmit chain of stages. Intermittent behavior is usually
the result of an unsoldered (or poorly soldered connection).

My recommendation is that you build up the RF probe included with the K2 kit
(or use a 'scope), then do whatever you need do to make the failure happen -
then while it is still in failure mode, go through the Transmit
Troubleshooting section of the manual - the first thing you should be trying
to locate is the stage where the signal stops, the stage just before that
point is where the trouble is located.  We can help better once we know the
location.

73,
Don W3FPR
