I downloaded, installed, and used the Radioddity software (v1.0.6) in early September without any issues. It's a typical CCR programmer ... *works*, but leaves a lot to be desired as far as features go, including the lack of ability to cut-and-paste. I also noticed that there is at least one menu item that isn't in the programmer (or at least I cannot see it). The software lets you pick English or Chinese for the voice prompts but there is no option to turn them off, which you can (thankfully!) do on the radio.
Grabbed the radio yesterday to play with it a bit more and decided to look to see if there was a newer version of the software. Did an Internet search and the first link was to the Radioddity site, where a new version is available. Downloaded and tried to install and Windows Defender flagged it as malicious. *Could* be a false positive, but it could actually be infected with something.
I noticed that the second result from the Internet search was to a programmer from RT Systems. I am a big fan of their programmers so I went ahead and bought and downloaded it (I already have their K-type programming cable but they imply that it will work with other cables).
I would highly recommend the RT Systems software. Yes, it seems a bit silly to spend $25 on software to program a $35 radio, but it works SO much better. Just being able to select a range of frequencies and cut-and-paste (or copy) them to another bank makes it worth it in my book.
Interestingly enough, I still don't see the "turn off voice" in the settings. Maybe they forgot to include that in what's visible through the programming interface!
