Tom,Hello, we probably do not understand each other. What changes do I do a patch? No changes. There is a completely new driver written to support the new radio. I was guided here by this article http://chirp.danplanet.com/projects/chirp/wiki/DevelopersAdd_a_Radio. As you requested, I have corrected the comments created the file tests/images/KYD_IP-620.img him and run the test. The test took place without errors. I can not do hg add, and then hg push to the repository. I attached files for re-evaluation.
