An important part of moving to a new QTH is grounding and bonding. One 
of the things I did in my professional life was teach grounding and 
bonding to audio and video professionals. Here's my tutorial on the 
topic focusing on techniques applicable to ham radio.

I moved into a new QTH 10 years ago. It was out in the country, but it 
was very noisy. Over the following year or so, I discovered that 
grounding and bonding was a disaster -- it violated very rule in the 
book. Once I corrected those fundamental errors, it's now pretty quiet 
most of the time.
