Notes

Uses Shuttle Radar Topography Mission, Version 2 elevation data for terrain generation.

Don't enter the minus (-) sign on longitude data.

K Factor of 1.0 is the true Earth radius, K Factor of Infinity is a flat Earth.

Reception is usually described as LR(50/90). This is a 50% confidence that reception will be received 90% of the time.
