A HIGH-FREQUENCY PROPAGATION PREDICTION PROGRAM FOR THE CDC 1604 COMPUTER.
Abstract
Two programs are presented, written in NELIAC 5M for the CDC 1604 computer: the basic geometry, which organizes equipment parameters for computer handling and makes preliminary calculations; and the HF Propagation Prediction Program, which calculates critical frequencies, losses, S/N ratio, and signal strength for each link. Average calculation time for each link for each time of day, month, and sunspot number is about 7 seconds, as compared to about 10 hours by hand calculation. Assumptions, operating instructions, auxiliary routines, description of outputs, and error indications are included. (Author)
