| If you think you might be the subject of convert eavesdropping, this circuit can be used to find the bug. If you don't need to find hidden transmitters but do work with RF projects, this same circuit makes a very handy piece of test equipment.

Sensitivity is user adjustable. A length of wire (20 to 30 inches long) can be used as an antenna when testing for bugs or locating hidden transmitters, or a simple probe can be made out of RG174 coax and a small capacitor for use testing or troubleshooting RF circuits.
