I downloaded, and booted from the Lunux Live CD version of Chirp, which uses the Xfce 4.8 OS. At this point, I just wanted to complete an upload and download cycle as a test. The upload cycle completed, creating an image file for the VX-5R. However, the same exact results were experienced upon attempting a download cycle (radio as the destination).
Just to make sure we're clear, Chirp uses the opposite definitions of upload and download. In Chirp, the first step is to click "Download from Radio." Then modify your channels. Then "Upload to Radio."
Has your radio ever been modified for out of band transmit? Is the image you're trying to upload from another VX5 that was modded? A mismatch of region bits is one thing that causes a clone error.
A little background: Yaesu uses an extremely primitive programming protocol. It simply sends all the bytes and hopes for the best. This is why there is no error reported in Chirp--there's no mechanism in the protocol for receiving an error report from the radio. The only error handling opportunity is to watch the radio's display and manually retry if needed.
As far as tweaking Chirp's code to resolve this, the only real opportunity there is to add some extra time between bytes.
