It also looks like you can use CHIRP:
Yes, the BJ-218 works with the Luiton LT-725UV CHIRP driver as well as the factory software. I have one of each, an LT-725UV and a BJ-218, factory software and files are interchangeable, and I was able to write my LT-725UV CHIRP .img file into the BJ-218 without issue. My only question is when will the LT-725UV driver go from 90% to 100% and leave the Beta stage?
