Abstract: A user's guide and programmer's reference manual is presented to facilitate the use of two high frequency circuit analysis software systems called VOACAP and REC533. The guide shows how to execute the software on laptop computers and personal computers to make point-to-point predictions used to coordinate frequency assignments for broadcast planning. The guide shows how the software can be executed interactively for single circuits from menu-driven software, and for a collection of circuits in batch mode.

Keywords: propagation prediction; frequency assignment; high frequency; propagation model; HF broadcast planning model; VOACAP; REC533
