MacTNC - MacTNC is simple, configurable terminal software used by amateur (ham) radio operators to control a TNC (terminal node controller). MacTNC performs most of the same functions of other terminal software, but includes buttons for standard commands, and allows the user to configure additional buttons for special purposes. MacTNC works only user Mac OS X because it relies on Unix components of the current operating system.

ICOM OCX - CI-V OCX For The Icom 756Pro allow you to interface your own application or visual basic, excel, word or similar custom applications to your icom radio.

RevLoad - This graphics-intensive program reveals the load on the output of a matching-network, based on measurements of the components in that network. Adjust the network (tuner) for a flat input, measure or look up the network component values and you will immmediately see the R and jX values of the load on the network, presented as both a schematic with the component values and as a Smith Chart normalized to the specified system impedance.

Ham Radio Control Libraries - Hamlib is a library aid for software developers wishing to incorporate control of amateur radio hardware into their programs. Hamlib will allow ham radio software authors to concentrate on the user interface and the basic function of the program rather than radio control.
