Thanks to everyone who offered suggestions to my radio interference problem. I
am hoping thay I'll get some more time on the weekend to investigate it
further. Sorry for the delay in responding to the replies I received, but
here goes...

Are you hearing radio stations, 60 Hz hum, static, or what?
Are you near florescent lighting? (like in the floor under your feet...)
It's radio. I don't think lighting is the problem, nothing unusual around the
equipment that wasn't there before.

Check your local electronics places for RF filters. A
number of power
strips or surge protectors include them.
Thanks for the tip, I may have to look into something like this.

What you are experiencing is called rectification... a

fixable with a little work...

You may need to buy some ferrite beads and place them
on the cables where
they break out to your sound panels... generally you wind it around the
hot leads (not the ground) and reconnect them to there respective
terminals...
Allot of work... yes... but it will work...
I'm not sure what you mean by ferrite beads, or how to place them on the cables?
What leads are the hot leads on the cables (I assume you are referring to the
XLRs?) Sorry for being so dense, but I'd appreciate it if you could explain
this to me in greater detail (like a two year old, say?) ;)
Thanks again to everyone who replied!

If it hasn't been suggested already, get one of those cheap plug-in
circuit testers from a hardware store and make sure all circuits are
grounded properly. I keep one in my guitar case. This is a good idea
for safety reasons anyway.

I second that suggestion. You changed locations, so the circuits your
equipment is on now are different from before. If your circuits are
shared with notoriously-noisy electrical equipment (washers, dryers,
stuff with electrical motors in them, IIRC), RF filters and power
conditioners will make the difference.
