If they aren’t listed on CHIRP, then you’ll have to go on a google expedition to find the software for it. There are some radios that I have that I was NEVER able to find the software for (Baojie BJ318, KSUN KG-UV68D, etc).
Since I buy mine on eBay, some of the sellers will email me the software if I inquire about it.
For some reason, CHIRP doesn’t seem too eager to add some of these radios.
