I have a V82. I have a programming cable #SN: HNT1208A002. I have the CHIRP software. I have tried several com ports. I have tried 2 different computers. One with Win7. The other with XP. Same problem with both.   I can't get the radio to talk to the computer. When trying to download from the radio I get the error message: "Unable to probe radio band"   Don W7OUI
