Okay, an update:
My computer--with the emailed copy of the software on it--crashed. And so began (again) the search for the software for this $99 radio. First, I decided to translate what was printed on the label on the back of the radio (using a translator app on my phone). When translated, it says:
"Stepcom Professional Walkie Talkie Model: X-UV68D (MAX Version)
Power: 8W
Frequency: 400-470MHz
Quanzhou Buxon Electronic Technology Co., Ltd."
Why it says that its only one frequency band, I don't know.
Anyway, through more research, I discovered when I googled KSUN X-UV68D, it gave me a website for the Wanneton/Wannlitong UV6F, which is identical to the KSUN. Also, when I googled just "X-UV68D" it came up with a bunch of results for Baofeng and another company, Abbree, where the same radio is known as the AR-F6. I could not get any results for either Stepcom or Quanzhou Buxon.
Although Wanneton/Wannlitong mentions the radio in its product line-up, it does not offer software for it.
Abbree doesn't even mention the radio on their website, despite the fact the several online sellers show images of the radio with the Abbree name on it.
Search results for the WLT-2000 were equally unsuccessful.
As for why Baofeng keeps popping up, I also have no idea.
Either way, I could not locate any software.
Although I know I maybe posting something that might not elicit a response from anyone, this thread does feature prominently in the search results. So maybe someone reading it from there will be a little more informed about this radio.
Oh, by the way, the radio seems to have the tendency to turn off and then on again by itself when left on for an extended period.
Just FYI, the link to the programming software on the YouTube video is missing, so I was never able to try that.
