From what I gather, Northstar is dispatched on REMCS CH5 and Southstar is dispatched from Voorhees in Glouester County. I have not been able to find the freq for Southstar alerting anywhere. One website specifically stated that Southstar is dispatched on the NJSP trunked system, TG 26800. Can anyone confirm this or point me in the right direction as to obtaining the correct Freq ?
