Tester;
Will this method permanently change the contents of the MLM so that it
will always be a C7 or will it need to be forced each time a change is made?

It is possible but probably easier to just dump a trunking compatible
codeplug into the 450 radio without changing the actual MLM module.

If you really want to go to all that trouble, then look at Batlabs. There
is info there on which byte of the MLM to change to designate the radio's
freq band. Install your new MLM and you will get FAIL 999. Use Lab to
change the MLM and Command Board serial numbers to match (make them match
the radio). Then you will get FAIL 001 since the MLM data is out of range
for your radio. Use Lab to change the freq band to the correct one (and
also use it to change the model number, etc as specified on Batlabs).
Finally, read the radio codeplug and delete all the systems/modes since
they will be invalid. Change the ones remaining to valid UHF data and
rewrite the radio. This should work. I have done it from UHF to VHF, and
800 to 900 with no problems. But you do run a risk of screwing up by
changing the wrong values somewhere in lab. Then you could have a useless
paperweight unless you get another new MLM.

So, forcing in a trunking codeplug is easier.

Tester;
I have an 800 MHz C7 MLM that I would like to use to upgrade a 450 MHz
A5 model. Is it possible to do this with "lab"?
