This is with power to you entire building killed?  Main breaker? Individual 

What is your power system ground?  What is your shack ground? How are they 
connected to each other?  

Another thought -- have you checked your home for bonds between neutral and 
the green wire?  Have you checked each outlet for proper wiring? 
Electricians make mistakes. An outlet wired wrong, or an extra 
neutral/ground bond can do lots of mischief.
