GE Mastr Pro



Here's a nice little chart to help figure out what your radio does. For example, my Mastr Pro is an MT75TCU88, which translates into a 12V trunk mount mobile at 450 MHz with 25KHz channel spacing, a transmitter that will handle two frequencies, has a power output of somewhere between 60 and 130 watts(depending on specific transmitter, mine does around 60W), and the channel guard option.
Be sure to email me if you notice any errors or have any addiotnal info.
