The noise sniffer can be used with the vehicle radio in order to locate hot spots generating radio noise interference. Hot spots can be found in the following locations:

Making The Sniffer

1. Make the sniffer from an old piece of antenna lead-in from a mast or a power antenna.
2. Remove the antenna base connector from the antenna lead-in (4).
3. Cut away 2 inches of the coax shield (3).

The 2 inch section with the braided shield stripped back becomes the antenna when plugged into the radio antenna socket.

To Use The Noise Sniffer

1. Listen to the complaint noise.
2. Disconnect the antenna.
3. Plug the antenna into the antenna socket in order to probe and search out hot spots.
4. Turn the radio volume up.



5. Search for the noise (1).

Keep your fingers off of the 2 inch probe. For best results place the sniffer (3) parallel to the wire (2).
