[Elecraft] K3 #2257 woke up deaf this morning ...

[Mike Flowers]

Thanks, Bob.  I powered it off and on a couple of times and it came roaring back to life.  

 In many ways this behavior Is just as disturbing.  

When I have a couple of hours I’ll put it on the bench and exercise (gently) the internal connectors, etc.  

Thanks for your suggestions!!
