MPSCS Oakland County Simulcast

I have noticed a second control channel on 855.6625 MHz, is this a P25 TDMA control channel?

That is kind of an enigma. DSDPlus says detecting p25 phase 2 then just displays a constant string of "bad decode".

Its not a CC. I dont know what it is transmitting. Maybe some type of test?

Edit: If it is a phase 2 CC, dsdplus fast lane can handle it, right?

I believe it will decode Phase II TDMA. There's a whole thread on this subject.

When they were doing the extensive testing last week, DSD+Fastlane was showing the 700mHz voice channels as 2-slot TDMA. The control channels were P25 FDMA.
But this 855.6625 is showing nothing.

When doing coverage BER testing one channel is put into test mode and generates a test pattern. That test pattern is decoded by the test equipment and the BER testing is based on that.

So if you see a channel on the air that isn't control and is on continuous that's probably what it was. While I'm no longer actively involved in the project (haven't been for a couple years) I saw the test kits in the engineers office so Ido know that they were / are doing some testing.

Any Updates on System Implementation?

Will Fire be encrypted?

Still testing and installing radios.

doesn’t look like it, but county havent pushed out the codeplug yet

I hope that the page out is not whatever crap Commerce Twp recently changed to. It sounds awful, and gives out a lot of useless info

Probably Bryx. Automated dispatch is supposed to speed up call-received to dispatch, using basic info. It reads off the CAD. Call details come later in the apps as they get it. There are several vendors, but Bryx has taken hold in SE MI. The system is flexible and has all sorts of options and features. It's a budget version of the fancy big name station alert systems.

Automated dispatch is not related and independent of the radio system project.

I have noticed that TG: 32330 has patched audio from another radio system. However, it's completely encrypted, but there are few portable radios talking from the MPSCS side through the patch.

I would have to assume its patched with some talkgroup on Opensky.

 

[RayAir]

A couple weeks ago they were patching from OpenSky to 63PMATA but it was in the clear. 63COM was used a little also.

Yes, that would be correct.

Hearing:
Ferndale Fire Dispatch 32175 first time in 20 years
Hazel Park Fire Dispatch 32183 first time in 20 years
Madison Hgts Fire Dispatch 32229
Southfield Fire Dispatch 32274
ALL IN THE CLEAR on the new Oakland County Simulcast
DREAM CRUISE: Heard Berkley Police and Bloomfield Twp Police IN THE CLEAR: J Event 48, J Event 49, J Event 50.
Today (21st) The Police are back to encrypted. But fire remains in the clear.

I was just thinking the same: I have heard Ferndale, Hazel Park, Madison Heights, and Southfield.

Does anyone know when others are going to be added to RR and how long it takes from when they're added to when they start working?

Added as in streaming? Or added as in to the database?

 

[bkirk3434]

@Forts added as on the RR MPSCS site with an assigned DEC # and alpha tag (the database).

No time frame for things being submitted to the database... it's either as things go live and are identified or when someone in the know chooses to submit.
