VOACAP – CHU to VE3PKC+

In a previous post Ref.1 I looked at VOACAP and it’s use in a simple off air receive situation. In this post I will delve a little further into the software and compare the results against some simple mathematical models. VOACAP (Voice of America Coverage Analysis Program) is free professional high-frequency (HF) propagation prediction software […]
