Looking for instructions on a sound masker to defeat listening bugs? Answered
I have a friend who is going through a rough divorce and we think it is quite likely that he has bugged her house. He has used electronic bugs in the past, his daughter is mentally and physically handicapped and he put it on her wheel chair to hear what happened during her first day of middle school. I am looking for cheap instructions on how to build a device to detect it and/or instructions on a device like you read about in espionage books that produces noise that makes anything a bug picks up unintelligible.
