Abstract
Abstract A dual system communicator includes an electronic analog communicator and a removeably attached power source. The analog communicator includes analog signal transceiving electronics. The power source includes digital signal transceiving electronics. The analog communicator and the power source are wirelessly interfaced for communication between the digital signal transceiving electronics and the analog signal transceiving electronics. The dual system communicator is operational as a standard analog communicator or as a communicator capable of receiving digital signals which are converted to analog signals by a converter and transmitting analog signals which are converted into digital signals.
