VOACAP

 

VOACAP (Voice of America Coverage Analysis Program) is a powerful tool for predicting and analyzing HF (high frequency) radio propagation. It is used by radio operators, engineers, and researchers to predict the coverage and signal strength of radio signals in different parts of the world. VOACAP can consider factors such as frequency, time of day, and solar activity to predict the expected signal strength and coverage area. It can also optimize antenna systems and select the best frequencies for long-distance communication.
