W6ELProp(tm) - free propagation software

[Linnea]

W6ELProp predicts ionospheric (sky-wave) propagation between any two locations on the earth on frequencies between 3 and 30 MHz. There is no charge for W6ELProp when used for non-commercial purposes.

This is the primary W6ELProp distribution site. Any new version of W6ELProp will first be available at this site.

Version 2.70 permits the user to specify a terminal location by its IARU Grid Locator, and permits the user to optionally display areas for only one prediction frequency at a time in the Frequency Map.
