Wall Fire 7, 153.830 PL 151.4, is Monmouth County Fire 7, which is simplex. Also you have listed separate FG Channels for Glendola and South Wall and I was wondering if one of the other FG channels was specifically assigned to 52-1, Wall #1.
West Belmar does not have a fireground channel assigned to them. Other departments might use Spen 4 for helicopter ops, our departments in Wall uses a county channel assigned by county.
