Station 39 is Oxford, Don't remember a Signal 50. The only signal I can remember is 11 for an accident. Now it sound more clear speech, listening on Broadcastify. Been a long since I used then when I dispatched for Lopatcong PD, for out part of Warren County out of the basement of Lopat PD building. Helped number the police, Alpha-82, Belvidere-21, Greenwich-57, Lopat-74, Pohat-75, fire companies Alpha-82, Belvidere-21, Harmony-23, Delaware Park &/Lopat-74, Huntington-75, Stewartsville-98 and squads for Belvidere-21, Greenwich-57 & Lopat-74 back in the late 70s that we dispatched for.
