So far...
I have concluded that of the 3 towers I am closest to (Howell, Northville, Holly) I am closER to the Northville and the Holly towers. I have entered in Livingston County EMS agencies, FD's, and HVA talk groups. I am hearing the same Livingston FD, EMS and HVA units on the Northville tower AND Holly tower channels. Not hearinig much on the Howell tower. So in conclusion, it is ok to put the multiple control channels and their alternates in the same bank. There is not much "fighting" between control channels. I hear LCA on Northvilles control channel AND I have heard them on Holly's control channel. Does anyone else have this same kind of set up?
