Which frequency would that be? They may have been grandfathered in.good they are changing... then they'll get off of the MURS frequency they are currently hogging.
I seem to recall one of the departments in Fairfield County was using a VHF frequency to link to the SO repeater for portable coverage in their village. That may be it but you're right; still not a good frequency for that purpose.Murs Channel 1 151.820 It is a link on their UHF system. I actually addressed this exact point in a much older thread soon after MURS came to be.
Grandfathered or not, a MURS user can potentially (accidentally or otherwise) interfere with communications. Not wise for any public safety agency to utilize a license free public band.
I would bet they go with MARCSIP. It is cheaper than installing and maintaining your own system.I believe their system used VHF voter links at one time... Seems like a step backwards if they are not going MARCS-IP. I know money is tight for everyone but that does not help with LEO interop.
