MeteorSim - HSCW/WSJT meteorscatter/path simulator a first attempt at trying to model meteorscatter events and simulate their transmission characteristics

Ham Profile - This database is not a logging program. It is intended to collect information about the HAMs that you know. You just record the call sign and name of a HAM that you meet. Later you can use QRZ to look up the call sign to validate that it matches the name.

AZMap - Azimuthal maps generator - AZMap is a freeware Windows program for the Windows PC which will generate, display, and print an Azimuthal-Equidistance (A-E) map of the world, centered at any point on the surface of the earth (except very near the poles). The A-E map is also known as a Great Circle map since straight lines from the center point to any other point always fall along a great circle path and represent the shortest distance between the center and that point
