Trying to program my Baofeng BF-F8HP radio with CHIRP software that I have downloaded. The download went fine. The radio is brand new, and the cable is of high quality. When I open the software and go to the menu, I select "download" from radio. Once I do that, I get a box that has three dropdown, "Port" is first, followed by brand and model of radio. Brand and model I selected with no problem. However, when I go to port, it's blank. I guess it may be a driver issue, but that's just a swag.
