Unless something has changed, the system was put in place several years ago in hopes the surrounding communities dispatched by Goffstown would join. None did and eventually Goffstown was the only user, with police, fire and DPW. Fire always maintained their 158.880 frequency for interoperability, originally patched to a talkgroup. Fire left the system using only 158.880 and police eventually did as well returning to 155.190. DPW will be last to leave.
