Not sure why they’re throwing so much shade, the links posted don’t even have the information your looking for.
Beverly, Danvers, and Peabody don’t use 2 tone paging.
Lynnfield might as they are a call department at night, but I don’t see the tones listed online anywhere. I was listening last night during an accident on 95 and thought I heard tones. They also had a fire early this morning that might have something. It might be worth pulling the tapes from here and seeing.
