CHIRP is a free, open-source tool for programming your amateur radio. It runs on various computer platforms, supports a large number of radio manufacturers and models, and provides a way to interface with multiple data sources and formats. Many new radios can connect to your computer. Each uses it's own software to program the radio--which helps the user, but users often have to learn different software and re-enter the information for each radio.

CHIRP allows one piece of software to be used with many radios. Create a set of frequencies, ofsets and PL tones once and then upload them to each radio. Many in the EARS club want to be able to communicate on local emergency communcations frequencies and have programmed those stations onto our radios using CHIRP. In order to help others not have to program so much information into their own radios, we have provided Willamette Valley area emergency communications frequency sets that you can import into your own CHIRP application and upload to your radio.
