[Repeater-Builder] Motorola Portable project

[David]

Does anyone know where I can find the COR or COS point for a Motorola 
P110 or GP300. I am working on a portable repeater and would like to 
use a typical controller with COS circuit and not just audio. I am 
familiar with the portables but as far as reading a schematic and 
finding that plot on the radio itself, I am at a loss. Thanks in 
advance.
