Looks nice, isn’t it? 10W output power, this is not a joke. Just imagine my frustration when I found that CHIRP software, which I previously used with UV-5R, and which is de facto standard for such devices has no support for BF-H7!
After some digging, I discovered this thread which says that there is no hope for BF-H7 support in the nearest future.
Some googling lead me to this video where I have managed to find the answer!
To program your BF-H7 with CHIRP you should use settings for the Radioddity GA-510.
It works perfectly fine and allows you to set channels and all necessary settings, except a start screen and other minor things.
I hope this post will save you time and help you to enjoy a new toy.
