Tower - Windows program for analyzing vertical antennas. This program shows the resistance and reactance to be expected looking into a cylindrical metallic tower over a perfect ground. It gives a useful approximation of the values to be expected in a real-world situation.

Grig Radio Control - Grig is a freeware simple Ham Radio control (CAT) program based on the Ham Radio Control Libraries (Hamlib). It is intended to be highly generic presenting the user to the same graphical user interface regardless of which radio is being controlled. Grig supports the most commonly used CAT commands that are implemented by Hamlib, and integrates well with other ham radio programs like Xlog and gMFSK. Grig has been developed on Linux, but has been ported on Mac and Windows OS.

Aether - Aether is an ham radio logging for the Mac. Aether gives hams logging software that is as powerful, easy to use, and good looking as the operating system it runs on. Designed from the ground-up using Apple�s Cocoa, Aether supports the latest Mac OS X technologies, and provides the experience that Mac users expect.
