CHIRP

Hi. New to the community. I was successful in downloading the CHIRP software and installed the drivers for the MAXTON DATA cable Model:RPC:K1-U. Once the drivers were installed, I could chose a COM3 as the single option when working with the "Download from Radio" menu option.

I connect the cable to the radio, turn it on. At this point I notice the radio has a flashing "PF3". I then press "OK". Nothing happens with CHIRP at this point. The only think I do notice is that the flashing "PF3" on my radio now no longer exists and I just have a normal frequency showing. If I run through the cycle again, I get an error message stating "could not open port COM3: [Error 5] Access is denied". I can restart CHIRP and run through the cycle again and the process repeats.

I'd appreciate any advice.
Thanks,
Lee
