Maybe try contacting Paul B., ?RadioCW98? on here. He is the Prez of the Boston Sparks Asso. If anybody or any group would be able to help you regarding your question about the Boston area, he can or anybody in that organization can.
There a a few options to listen to BFD or Boston area radio. Google Boston Fire Radio. Also, visit Boston Fire Museum. Run by Boston Sparks. They are very active and welcome visitors. They respond to working fires in Boston area. Also consider visiting Boston Fire Alarm. Great Chief.
