I was hoping that someone may know what frequencies are used for the Allegheny County Coroner and Fire Marshalls of Allegheny County. I know that they use to use 470.3375 but that is know used by the Sheriffs office of Allegheny exclusively I do believe. I have not heard the Coroner or the Fire Marshall on that frequency that they use to use. Thanks for any information on this topic or any other frequencies that they may use to be dispatched or for their operations!!!!! THANKS AGAIN!!!
