These two cable connected together allow me to connect my usb port to the vx8-g.
On the DB9 to 2.5mm plug, it was not made for the vx8, so I had to use an exact-o knife to cut away some extra plastic molding so that the 2.5mm connector's tip would fit past the radio's case.
Now I am waiting for the software to be ready. I tried the vx8dr software but and it connects to the vx8g but them lets me know I have an unsupported radio. The serial connection does work and I can see the radio in clone mode send its radio number over the connection when I was detecting the port number.
