The third edition of Near Vertical Incidence Skywave Communication by LTC David M. Fiedler and Maj Edward J. Farmer is a comprehensive guide to NVIS (Near Vertical Incidence Skywave) propagation, a technique for short-range HF (High Frequency) communications. This NEW edition, published by Jokalym Press in 2023, spans 164 pages and is particularly valuable for amateur radio operators and emergency communicators.

📘 Book Overview*

NVIS is a propagation method that utilizes high-angle ionospheric reflection to enable reliable communication over distances typically ranging from 0 to 400 miles. This technique is especially useful when VHF/UHF frequencies are ineffective due to terrain or other obstacles. The authors draw from extensive military experience to provide insights into NVIS theory, practical applications, and validation methods.
