There is almost no information to be found on these radios anywhere on the Internet. Most of what you find are questions with no answers. A few years back I started keeping an eye out for these radios, and over the years I've come up with a few things. I’ve finally scanned and photographed the things that looked like they’d be useful, so here they are. I’m posting this in 40 Tech because at least some of the information is model specific.
