Hi

I have programming cables for the Baofeng UV-5R and a Yaesu VX-7R which I suspect are based on cloned Prolific chips and give me no end of trouble with Chirp (and VX Commander for the Yaesu)

I spotted the Miklor website that gives information about building a cable for the Baofeng using a CP2102 USB/TTL UART.

I was thinking that rather than soldering the cable for the Baofeng directly to the UART board I could put the board in a small box with a USB extension lead one side and with a 3.5mm stereo jack on the other. I would then terminate the programming lead for each radio with a 3.5mm plug wired appropriately. The Baofeng connections I can take from the Miklor website above but what would I need for the VX-7R?

I found this pin out for the VX-7R

This seems to be similar to the Baofeng UV-3R (as shown on the Miklor page) but is a Ground connection required?
