[Elecraft] K2 headphone jack failure question

[Don Wilhelm]

  John,

I believe you have caught a different bug.  The usual failure is that 
the headphones still work, but the speaker does not - sometimes the 
speaker stays on even though the headphones are plugged in.

It sounds like you have just lost all audio, and the reason for that can 
be widespread throughout the receiver.  Does the S-meter move?  If so 
that rules out a failure prior to the 2nd Xtal filter.

A signal generator and a 'scope would be helpful for your Receiver 
Signal Tracing (see Appendix E in the manual).  If you have neither, 
consider building the signal generator shown in the manual and the RF Probe.

73,
