Description

I sell programming cables for a living, and I have run into a problem that I just have not been able to solve. The UV-82WP, UV-9R, and UV-9RPlus that I own and use to test my cables in theory all use the same firmware and programming cable. In reality, the UV-9R series radios do not work with most of the cables that do work with the UV-82 and varients. This is a problem with both Chirp and the WP970i software. I have tried various USB to serail adapters with Prolific and FTDI chipsets from different cable manufacturers that I buy from, and the results are the same. I have used a USB packet capture tool that confirms that data is being successfully passed in all cases and it is not a serial communications problem. I have also confirmed that the data being exchanged differs between successful and failed programming attempts.

I am opening this bug report on danplanet.com to socialize the problem, and perhaps someone has figured out the root cause and to ask the Chirp team if we can have a developer investigate and maybe come up with a workaround in Chirp. I can provide radios, cables, and more details. I can be reached by email mark@bluemax49ers.com
