MPSCS Rebanding

[feta92]

For those of you that still have questions when the rebanding will take place, I found this today hopefully it answers your questions

When does st Clair county does reband

[hazard78]

MPSCS already was in St Clair Co. for rebanding back in September of 2012.

Wow. Finally! Will the new freqs be just 15 MHz down, or will it be more complicated than that?

[rdale]

Don't change anything yet in your scanner. This is just setting up the radios for when they "throw the switch."

[whacker]

Yeah, okay. I guess I hadn't thought of that. And I know they'll run both sets for a little while (or so it's been said), so I'll just wait 'til around the 11th through the end of the month before I put 'em in, run 'em and see, check for posts here and keep my eye on the database. Thanks for the caution.

My guess would be that you've got probably another 2-3 months before the trunking sites start being rebanded. They have to finish reprogramming all of the radios before they can start changing over the sites. This is just a guess though.

The way I understand it, the sites that needed to be rebanded are running both the old & new frequencies now. Once all the radios in the field are reprogrammed, the techs will go back to the sites & delete the old frequencies. And once they've done your county, you'll want the new 8CALL90 & 8TACxx frequencies programmed in if you don't already (That is if your county uses them at all).

[rdale]

No, they don't transmit on both at once.

[drdispatch]

I didn't say they did.

They are *capable* of using both.

But I will defer to someone who has a broader knowledge of the system than I, since I am *just* a dispatcher.....

[rdale]

Sorry, I must have been confused when you said they are running both sets now. They are capable of using the new freqs, but they are not running them now.

The 8Call and 8TAC channels are running back to back. The actual trunked frequencies are only running on the old frequencies at this point. Those won't change (at least the control channels) until all of the radios are reprogrammed to be able to use them. Voice channels could be rebanded prior to that but the control channels still need to be in the 866-869 range since that's the only place the radios that have not been reprogrammed for rebanding know to look.

Thanks for providing a more complete explanation, Mike. That filled in the holes.

And according to the schedule feta92 posted, my county is supposed to be done the 18th, 22nd, & 23rd of this month. One of the Assistant Chiefs told me that they don't have scheduled times; they were told to "just show up". With as many radios as we have in the metro BC area alone, I hope they don't all show up at once....

When we did the re-banding on all of the radios in Barry county we didn't have set times. We were just told to show up in Hastings on December 10th. Almost everyone showed up in the morning and had most of the radios done by noon or mid afternoon. Wasn't that bad at all.

That link has a lot more information than the original. (Found while searching for Washtenaw County information)

I just recently got my IC-R3 working with DSD and can't seem to get a decode on the Washtenaw simulcast, although the Wayne county system is working fine (I can decode from Northville, and Romulus towers)

The January MPSCS newsletter says that rebanding is generally completed for about 34 counties, including most counties south of M-20, including the Midland/Bay City/Saginaw area. The major concentration from now through March will be the Detroit Metro area - the counties of Monroe, Macomb, Wayne, & Washtenaw. So far more than 19,000 radios have been rebanded (whew!)
