Your right, I was in a bit of a rush, let's for get the question.This is very poorly written. Difference from what? What dispatcher? Where? Do you have your AGC set up? Is this frequency really a narrow banded one? What is the frequency?
Please, a bit more detail here is needed before anyone can intelligently respond
Check the AGC settings. Go into the menu then settings then select Adjust Audio AGC. I have mine set to the following:The one thing I notice is the difference in the dispatcher volume even though the signal strength is max out. Is this something that I have to live with or is there a speaker mod?
