I wrote most of the FT-2900 driver, and I'll maintain it as needed. It has been pretty stable for quite some time now, and I've had good reports from people who have used it, so I'm confident it's basically working, but there's probably room for improvement.
Thanks, David, for the suggestion about the lock button. I haven't tried that, and I'm away from my radio right now, but there may be something I can do to the driver to make it at least give a better error message when that situation is encountered.
Al: If you can download from the radio, then your cable is almost certainly working. Downloading requires communications in both directions. There's a remote chance that the cable length, impedance, or some other analog characteristic is such that it's producing intermittent problems, but I doubt it.
If it's not the lock issue which David suggested, then contact me off list, and send me the file you're trying to upload. I'll take a look and see what I can discover.

Al, I don't know if this is your problem or not but it is something to check. The last time I tried to program my 2900 the radio wouldn't accept the upload. Then I realized that I had the lock turned on when I had used it the time before. As soon as I unlocked all was good. I haven't had the 2900 long and it took be a couple of minutes to notice the lock icon.

Hello, I just joined this list and I am pulling out my hair trying to figure out why CHiRP won't upload to my new Yaesu FT-2900r.
I am on my third cable. It is a Valley Enterprises FTDI cable using the proper driver software. I can download after following the procedure to hold the A/N Low button in while powering on the radio then reading from radio.
I have great success with using CHiRP with all my other radios, but the FT-2900r cannot be written to.
Please, any thoughts. I tried looking at a CHiRP forum, but something was wrong with my account.
