I'm just running through all the options that I can to eliminate as much artificial noise that I can from getting to my scanner and ran across this little article about EMI/RFI that is emitted because of LED light bulbs. I never would have thought about it, but it's right in the 30 - 300 mhz range. I replaced the ones that I had with cfl's.
So, if anyone else is experiencing the interference issues, read this.
