Attach the MTTX anywhere along a phone line (a simple job that takes just 5 minutes). You then tune an FM radio into the signal and you will hear exactly what both parties are saying.
The MTTX starts transmits only when the phone is used. If you have a radio/cassette you can even record the conversation for future playback (the Telephone Recording Interface may also be used for this purpose).
Uses a 2-transistor circuit with an RF transistor in the output stage to give a clear, stable signal. Draws it's power from the phone line so is completely maintenance free once installed.
