In order to make the contesting life a little easier, we provide some files you can use to program your radios. The Channel number in each file corresponds to the repeater’s “Repeater Roundabout Number” (RR#) which you need to log in the contest.
These files are automatically generated each time a new repeater is added. Many thanks to Mike K7MCK for contributing code to generate the AnyTone D878 and Icom IC-705 files, and for the videos you see below on programming your radios specifically for the Repeater Roundabout.
Chirp is a free, open-source tool for programming a large number of radios.
- You’ll want to check that Chirp supports your radio.
- You will need a programming cable that works with your radio. Chirp has a guide on the subject, and Dave Casler KE0OG has a video on the subject for some of the common Chinese radios.
- Install Chirp on your computer.
- You are now ready to test cloning from your radio. If this works, your radio and computer are correctly communicating, and you are ready to write our CSV file. Dave Casler has a good video to get you started.
For more information, check out Chirp’s Wiki.
