I was reading the Sheboygan County Radio System Committee minutes, and it was mentioned that surrounding counties, Fond du Lac and Washington were moving toward new radio systems that could affect interoperability communications depending on system type.
It's funny that Sheboygan County is complaining about interoperability between them and Fond du Lac or Washington county. They were the ones who went to a 800Mhz system. Washington will still be on VHF with their new system and Fondy will stay VHF. Nothing will change between Sheboygen and the other counties.
Here is info on Fondy's "new" system. They are just adding more towers, going narrowband with digital capabilities and simulcasting.

Fondy county minutes
"The Radio Communications and Interoperability Project, under the direction of Ellen Sorensen, is advancing significantly in 2008. The project will continue until its completion by the end of March next year. The system includes six new radio towers and will feature a microwave back up system in order for the system to be completely redundant in the event of a telephone line failure. The system will have a digital interoperable channel so that emergency departments, whether local, state, or federal will be able to communicate with one another in the event of a major emergency within Fond du Lac County. It will have a simulcast feature that will transmit signals from all six towers simultaneously, therefore eliminating the redundant paging for the fire departments that can be disruptive and annoying for fire and EMS personnel. This project was undertaken due to the change in federal standards in response to the 911 disaster in New York which will require the implementation of narrow banding by the end of 2013. The County’s radio communication system is not sufficient to handle narrow banding and in fact has been a substandard system for many years. The new system will also meet the latest radio communication standards of clear communications in 95 percent of the area 95 percent of the time."
