Abstract

This work proves the feasibility of utilizing commercial broadcast facilities for emergency Department of Defense 100 wpm Teletype communications. The test network, which consists of ten stations, extends over the northeastern United States. Teletype communications is accomplished by frequency shifting the carrier of the broadcast station transmitter ±18 Hz. This submodulation technique causes no degradation to the commercial broadcast material and is undetectable on a standard home receiver. The tests that were conducted on this network between the terminals at Rome Air Development Center (RADC) Rome, N. Y., and the Federal Communications Commission Laurel Laboratories, Laurel, Md., proved the reliability and survivability of this communications technique.
