Chirp is a program designed to make changes to the memory of portable radio stations. With its help it is possible to change the frequencies of built-in channels, to transfer data from one radio to another, as well as to change the "callsign" of the radio receiver - a unique identifier of the device, usually consisting of 16-32 characters.
Chirp supports a large number of manufacturers and models of radio stations. Here's a partial list of the most popular ones: Kenwood, Baofeng, Icom, Yaesu, Alinco, Anytone and others. The number of supported models is extended with the release of new versions of the program.
The principle of operation is as follows: the utility establishes a connection to a walkie-talkie connected to the computer, then creates a device memory dump in CSV format, which is essentially a common table where each channel is assigned an ID-name, operating frequency and offset level. You can save data in other formats via the program interface and upload it back to the radio station after making the necessary changes.
The program also includes a set of ready-made presets - the most frequently used channel frequencies that can be loaded into your device, such as those used by truck drivers or the U.S. Coast Guard and Weather Service frequencies, which transmit information to ships.
Note that most walkie-talkies, especially older models, require a parallel COM port and the appropriate cable. If your computer does not have this port, you can use a USB to Serial adapter.
