OK, I spent over an hour searching every way possible through the FCC database looking for 700MHz systems. I found the LATIE sites in Slidell, LaPlace, etc. I even found one broadcaster still licensed in Hammond operating on a single 700MHz freq. But I found no record of any public safety system, owned by Louisiana, State of, or anyone else licensed through the FCC. Either the frequencies you got from your buddy are incorrect or SLU is working on a system that isn't legally registered.
