E3C11
What does VOACAP software model?
- A.AC voltage and impedance
- B.VHF radio propagation
- C.HF propagation (correct answer)
- D.AC current and impedance
WhyVOACAP software models HF propagation. VOACAP (Voice of America Coverage Analysis Program) is HF propagation prediction software, modeling how well a given HF path should perform based on time of day, season, solar activity, and station parameters, answer C. It doesn't model AC voltage, current, or impedance, those are basic circuit quantities, and it's built specifically for HF skip propagation, not VHF.
