Forgive me if this is a stupid question, but after you seperate the towers with a any freq. do you have to lock-out the other control channels or no? Basically what i want to do is have detroit simulcast, macomb simulcast, and monroe simulcast. I just want to make sure this is correct for the setup, I put Control channels for detroit in say bank 1, number 1,2,3 then i would put any freq for instance 154.xxx, then another freq 154.xxx. Then proceed to put Macomb simulcast, then do the same with seperation of freq's, then put in Monroe. After this is done, if this is the correct way, do i have to lock out any of the control channels, or just leave them be and scan away, or should say trunk away?
