[Scan-DC] Topic drift on RF interference

Oh, I forgot to add: the scaffolding surrounding the Washington Monument is now complete. It goes all the way to the top, 555 feet above the ground. That's 170 meters, give or take. I don't know who's on 1,764 kHz, but that sounds like parking lot information for Washington National Airport. They should get pretty good reception of WPGC too, don't you think? Whoops, that's WJFK now.

I've got amalgam fillings and guess my dentist(s) did something right.  

I work around transmitters of a slightly higher power range and I've never
had any issue with RF pickup.  Obviously, YMMV.

One area where we have had some issues with RF "interference" is at 
a location or two where neighbors had operating cranes.  At one location
where we had a 1000kW MW transmitter, the port folks about a mile away
would occasionally complain about arcing when they didn't properly ground
their lift equipment.  

We've got exclusively metal studs in our transmitter buildings, and they are 
bonded to the building ground when around the transmitters, but nothing
unique in the office areas.
