You need to install and use Wouxun 32 bit software to have all options. CHIRP does not have actual profile for KG-UV9G.

I received my KG-UV9G today. I did the same thing with CHIRP using the KG-UV9D Plus profile and it worked. But I did not write back to the radio, did not want to brick it like I did with 805G.
Then I installed KG-UV9G software 64-bit. But it was crashing when I tried to perform any function. Then I uninstalled it and installed KG-UV9G software 32 bit and it works on Windows 10 64 bit.
PS
Just downloaded from the radio to software. Edited few settings. Wrote back to the radio. It worked.

I attached screenshots of errors when installing and using KG-UV9G software 64-bit.
 

It's probably some ridiculous courtesy tone. SWR issue shouldn't affect that. If the repeater just sends its CWID all the time but nobody actually uses the repeater, there's probably nobody to talk to using it anyways; it wouldn't surprise me if the owner doesn't watch it either.

By, "sent a message" do you mean you transmitted from your radio and spoke your call sign? Or, did you do something else?
