It seems that South Portland services are broadcasting on 800. (ID 12880 for police) and the rebroadcast is on there old vhf freq 155.610. This would explain the drop in audio on the vhf channel.
They still have the cruisers on VHF. I hear them on the input. I have not seen any of their cruisers lately to see if they have 800 capability.
