Dave, Refer to FAQ items 1 and 2 at http://www.miklor.com/COM/UV_CHIRP.php These are the two most common causes of cable failure. I hope this assists.

I use the latest version of Chirp downloaded about 10 days ago. It worked well and did all the programming I need for the Beofeng uv5r, (different cable) Btech UV 2501-220. I had a small computer problem and after correcting the computer problem I could program the Btech UV 2501 but the programming cables for the UV5R have a problem. The one that I used over and over now puts my UV5R in a transmit as soon as i plug it into the computer. The other cable gives me an error message that says the Commport (1-8 ) wont work. What do I do. Thanks for any ideas Dave KD0TUN
