Ok, my guess is I'm using more or different features than any of the
previous testers (of they would have had this problem too!)...

Possibly. My hunch is that there is some other sort of read error on
the memory, so it's skipping the whole channel. I've been using Chirp
for quite some time with the VX5 and the first time I had this problem
was also the first time I tried programming a NFM / half-deviation
memory.

I'll clarify: After this point, I was never able to successfully
upload my previous img (180+ channels programmed). I was only able to
upload a new mostly blank img. Neither my "backup" image from last
week, or my newer one with the NFM channels will load, only the mostly
blank image (I need to try adding thing to the empty image to see
if/when it breaks).

It means a blank image with only slot #1 programmed.

I definitely need to do some in-depth poking. The first thing I'd like
to confirm is the half-deviation bit. All I know is that I've been
using Chirp for months successfully, and now have catastrophic failure
after using the half-deviation feature for the first time :)

To the innocent bystanders on the list: I would avoid using the VX5's
NFM / half-deviation mode with Chirp until I research this a bit more.
Or, if you're adventurous, try it and report your findings!
