Presented is a study to determine whether a transmitter in the power range of 2.5-kw output would be feasible as a strategic and tactical jamming transmitter, or not. The strategic aspect of the problem has been emphasized in this study. Transmitter T-217A was used in this study. It has a rated power output of 2.5 kw over the range 1.5 to 26.0 Mcs and would be advantageous as a jammer because of its mobility, low power reqirements, and great effective range. The disadvantages of this type of transmitter are the cost, high fuel consumption, and the training time required for personnel. A sample uest was theoretically conducted in which calculations obtained from the Alaska-Tokyo circuit of the U.S. Army Command and Administrative Network USACAN were used. The sample test shows that under propagation conditions similar to those predicted for November 1955, the jammer-to-signal ratio at Tokyo will be sufficient for effective jamming by a 2.5-kw transmitter. Jamming is effective regardless of whether or not sky-wave fading is present. Author
