Powered by Translate

by Jari Perkiömäki, OH6BG/OG6GThis is a work-in-progress guide to using VOACAP (Voice of America Coverage Analysis Program) - free professional HF propagation prediction software from NTIA/ITS, originally developed for Voice of America (VOA). This guide should get you well started with VOACAP. A more comprehensive discussion about the finer details of using the software can be found in George Lane's book Signal-to-Noise Predictions Using VOACAP. A User's Guide. The book is now available on CD-ROM.
