What do I have to do to add support for the VX-2R? I suspect I could edit the VX-3 code, or could somebody tell me if it Just Works anyway? I have read the list archives (and most of the main chirp_users list) but no mention is made of this radio. Google doesn't tell me much either.
As Rick said, start with the VX7 driver. The clone bits should mostly be correct, with the exception of the length of the last block. From there, you'll need to change the memory format to match that of the VX-2, which will almost definitely use different offsets for the start of the memory channels, and likely have a few other differences in the format itself.
The first thing to do is make a vx2 driver out of the vx-7 so that it shows up on its own in the UI. Then make sure you can clone out of the radio to it and determine the proper length of the final block. Then you should be able to save the image, even though the parsing code will choke on the actual contents.
When I started doing all this I used VX2 commander to dump the radio (gives you the length of the image) and then I can easily check memory one and find the stored frequency in the image dump (giving you the start of the memory section of the image). All in all, it's not that hard.
So far all I have done is strip the RS232 level shifter and support components off the USB-serial adapter, leaving the FTDI chip behind. I need to cut the trace to the VCCIO pad and link it to 3V3OUT, then link TxD and RxD together and off to a 4-way plug for the VX2r. It's easy to do, but it takes time.
I have also made a copy of the VX7 module and called it VX2, and it shows up in the UI, but I can't do any more until I have a serial interface to talk to.
I also installed VX2 commander under WINE, but I don't know if I'll use it. It runs, but of course I still need a serial device.
last time I tried to run vx commander in wine it barfed horribly, although I don't know much about wine. I use vx commander in a windows virtual machine very well.

Thanks everyone for your interest. I am writing this all down so that someone can speak up if I am about to do something stupid.
