Hamlib
Developer

The Ham Radio Control Libraries, Hamlib for short, is a development effort to provide a consistent interface for programmers wanting to incorporate radio control in their programs. Hamlib is not a complete user application, rather, it is a software layer intended to make controlling various radios and other shack hardware much easier. Hamlib will allow authors of such software as logging programs, digital communications programs, or those wanting to develop the ultimate radio control software to concentrate on the user interface and the basic function of the program rather than radio control.
Hamlib’s focus is on controlling rigs that employ a port and command protocol for setting frequency, mode, VFO, PTT, etc. Most VHF/UHF transceivers do not employ such control capability but do provide for cloning the memory contents from radio to another of the same model. A related project, CHIRP, aims to support rigs with such a clone capability. Please contact the CHIRP project for support of such rigs.
