Rick,
I did some playing around with the original lt725uv.py driver. It should upload and download from/to the Luiton and Baojie radios (plus the alias radios).
I went ahead and changed name length to 7. It just won't display on the Luiton radio.
Also the Luiton radio has 3 power levels, but I could only find that would support 2 power levels via programming software. The factory software only allows programming 2 power levels (LOW/HIGH). The memory location only supports 2 power levels (it is a single bit). But the radios does allow you to choose 3 power levels when programming from the keypad (LOW/MIG/HIGH). Yes, MIG is what the radio displays as the 3rd power level choice. It was because of this weird implementation that I left the settings for the power level off.
I have attached my work as the complete driver so you can load it a a module and as a patch. It should give you some ideas for implementing the additional radios. I'm pretty sure you added support will work for the LT-725UV as well.
