So, after some buggering, I did find out how to get into the alignment menu, and figured out a couple of the options.
Hold PTT + MODE + EMG, then power on the radio.
Press the EMG then MODE buttons when you see the TS displayed.
AL = AM Limiter (modulation) - Lower is more max modulation
PL = Power Level (both FM and AM carrier)
R1 = Probably something to do with RX tuning, didn't mess with it.
F2 = Probably frequency adjustment, didn't mess with it.
Just be sure to write down your stock settings so you can return to factory tuning if you wish.
I did notice that this radio does have holes for a 3 pin jumper header, and two more locations for jumper wires. Didn't mess with those, but I'm guessing those are for the channel expansion.
