Hi Jacob,

Have you tried turning off all of the breakers in your house except your 
shack to see if the problem is in your house or your shack.  If it's 
still there unplug all your equipment, including the computer and 
monitor, except the rig.  It should be gone then unless your power 
supply is to close to your rig.  If it is gone, plug in each piece of 
equipment until it comes back.
