Here is a simple RF bug detector that will help you detect spy bugs and can operate up to 2 GHz. Below are some essential things required for this circuit: to cover a large frequency band make a sound ...

This design idea showcases a circuit that detects RF “bugs,” such as hidden wireless cameras, eavesdropping microphones, and other spying devices that emit RF frequencies in the 100MHz to 3000MHz ...

Cheap “spy bug” detectors are not good for much other than giving a false sense of security, a MyBroadband test of the K–68 Anti-Spy RF Detector has found. MyBroadband recently came across an ...
