I just got one last week, but haven't had a chance to use it much. So far I'm not able to get my computer to program it with the Retevis software. I should add, I hate computers, so there's that, lol. Anyway, I can't write to the radio from the software, which is inconvenient, as I need it for the cts tones that aren't listed in the manual, i.e. 114.8. Could be my computer. It is Windows 10, but it's getting old. Wish it were as easy as my Wouxun KG 935g+
