The current patch system, for the most part doesn't work. There is no direct access to the mpscs from the current system. There are a couple of patch channels that don't work. They specifically said you could try calling on them, but there's no guarantee someone will answer.
Interop doesn't exist. It's so bad there was a chase that started in Madison Heights and went to a foot pursuit/search. Madison Heights Police (OpenSky) could not communicate with MSP (MPSCS) while searching for the suspects while searching the area.
The only other option is to reboot your radio to access the 7/800 calling channels.
Then you have to reboot to OTP mode to get back on OpenSky.
For the most part, the voice quality and signal are pretty good with OpenSky, at least in the metro areas.
In neighboring Macomb County, MSP monitors MASH (both MPSCS) and assists them on calls quite often. They work together with CBP (MPSCS) as well. An officers' radio is his/her lifeline. It is so wrong in so many ways for Oakland to build out an expensive system within a system. Where is the oversight?
