What's the best method to connect a 3dr radio [ eBay version ] with a df-13 socket to usb [ pc ] ?? I need to set up one in MP and cannot see how to connect to my pc. The last time I did this several years ago it had the pins for the FTDI cable but now that it's just the DF-13 socket I'm stuck. Must be a better way than a bunch of pins and jumpers!!! ????
