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, SN 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
