Projects
that can be used for telephone monitoring in the U.S.A. or CANADA
without caller awareness require our "BEEPER ALERT" device.
Plans for kits are written and detailed for the beginner. The indicated operating ranges suggest the use of a properly tuned antenna and high quality communication receiver. WARNING - U.S. and Canadian customers must not connect any antenna to the transmitters that exceeds FCC regulations. Allowed radiated output usually equates out to a 50 to 200' range being enhanced by higher quality receiving equipment.
