Thanks for the link, and the comments.
One thing I was thinking of was a radio frequency meter, since I keep getting low signal between my wireless mouse and the base which are only 3 feet apart. My wifi router also has signal issues once in a while.
I wanted to setup a monitor to detect when an abnormal or stronger than normal radio signal is received and set off an alarm so I could measure the frequency and maybe even attempt to triangulate it.
Might find out someone with a high powered HAM is near me cooking me without me ever knowing
