I listen to MCSO/Gresham (Multnomah County) dispatch now, I know what most of the car unit #'s are except for the 4100 units...? Is that PDX Police Sergeants? Or ? Any info? Thank you.
And generally we only hear from them when they go 10-11 in the morning and 10-79 in the evening. They will occasionally key up to be attached to significant incidents too.
