[Elecraft] K3 Mini plug/jack mis-contact

[n6ax at speakeasy.net]

I am having some of the usual "dirty contact" issues with the 3.5 mm plugs....reaching back and 
twisting the plug in the socket restores normal operation.

I've seen this (as I a msure everyone else has) on lots of plugs with nickel (?) plating since 
that became the rage. Makes me long for the days of silver-plated everything......oh well.
