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

[David Wilcox]

When unplugging and plugging in coax connectors to improve the connection a spray of DeOxit on each end would be a good idea.  Works on all kinds of switches and connectors.  I wouldn’t hook up my four trailers to my car without it and those connectors are heavily abused.  Less so for my coax connectors but a good idea anyway.
