Don't know if this is a help, if you want another radio to
model for mods, there is another piece of open source software,
owx, that is available for the Wouxun KG-UV2D & KG-UVD1P which
looks like it has some details for frequency range modifications.

6.2. Frequency ranges

There are eight values below the channel table. They correspond to the RX
and TX ranges on both bands. By editing them, you can unlock your radio
(change it's transmit and receive range), but it's easy to kill your radio
by setting invalid values. If the ranges are invalid, the rig will refuse
to turn on, probably due to busy-waiting for the PLL loop to lock. YOU WILL
NOT BE ABLE TO REPROGRAM MEMORY USING ORDINARY CABLE. We've killed one radio
this way and in order to bring it back to life I had to open it, disable the
MCU (I just disabled it's clock), connect to the memory I2C bus and manually
reprogram it. If you lack appropriate equipment or skills you definitely
don't want to do this.

OWX performs some basic checks on the ranges when importing and warns you
if any value seems to be bogus, but it doesn't check the ranges (if you mess
with their order). Also, bugs in the importing routine are possible. If you
see any warning during importing, consider contacting me before putting the
resulting file to the radio, as it is easy to brick the radio and not so
easy to bring it back to life.

If instead of frequencies you see some hexadecimal values (0xABCD or so)
then the decoder (used when exporting) found unexpected pattern and refused
to decode the value. Please contact me and provide these raw values. It
should be safe to program them back to the radio, but don't change them
(they're encoded).
