BCD536HP AGC

I've got one trunked radio system where the volume is much higher than other systems in my Favorites Lists. As best as I can tell setting the AGC on might be the answer, though there is a volume offset for each channel.



So the questions are:



1. Is the AGC what I want to turn on?

2. If I turn the AGC on for this one system, should I turn it on for all the other systems?



Thanks!
