Margo Leftin

Abstract: HF radio propagation predictions are calculated for 35 circuits from the Voice of America transmitting facility at Tinang, P. I. and 30 circuits from their facility at Kava1a, Greece, using the OT/ITS prediction program. The program selects the optimum antenna at the facility for each circuit and the antenna identification and gain are listed in the predictions.
