CHIRP

Hello,

I’m a fellow UV-82HP owner as well… I’m new to amateur radio and bought this model to start out with and “venture slowly” in to the Amateur Radio world. I also had the same issue with my new genuine FTDI cable from Amazon not being able to connect from pc to radio. I would get the message “Unable to Read” or something like that. Until…. I ran across a reviewer on the Amazon site for the particular cable I bought and he said he had to physically press in on the connection end that is plugged into the side ports on the radio while it was reading. It worked! Now, I’m not sure if it will work for you because maybe you’re having a different problem, but thought I would offer it up anyway. The reviewer said something about the “fit” of the cable end that plugs into the radio having too much plastic around the jacks when the plastic was molded at the factory. My radio will not read to or from my PC unless I do this every time. It does not need to be squeezed hard, but a “Firm” light touch does the trick for me. You will have to hold it until radio completes its reading/writing process to PC. You may have to experiment a little. One reviewer said he trimmed some plastic. I just don’t remember which plastic he meant. Whether it was on the actual cable around the jacks or on the radio body itself near the female ports.

I tried attaching a pic of how I hold the cable when reading/writing to/from my PC. Hopefully it attached correctly...

Good Luck

I believe with El Capitan you have to use the native Apple driver and not the one from FTDI.
