Does anybody know if gratiot county ems/fire rebanded their 800MHz groups? I was recieving traffic on their TG's up until about a week ago. Its been a busy day in gratiot county today, and I know that 800MHz was used. If anybody knows about the change, if any, please post. Thanks

You can tell very easily. Listen to the control channel. If you hear noise, it has not been rebanded. If you don't hear noise, it has been rebanded. Program in the -15 frequencies and you should be set.

I went thru all the channels, and I hear no noise. And what do you mean by the -15 frequencies?

This means to take the frequencies that you listen to the 866-868 MHz range, and subtract -15 MHz from them. This would change the value to the 851 - 854 MHz range. For instance, 868.875 MHz, now becomes 853.875 MHz. If you hear any noise on these frequencies, then they have rebanded.

Oh wow, cant believe I had to ask that.. Thanks though. I did end up trying the -15 trick, and still didnt make any white noise. Although I checked my TG's and all of them on my BCD396xt says "finding cntrl channel." Not sure what to do from here

That most likely means they rebanded. Don't search, just subtract 15 and enter those as the new CC's.

I know they still do their nightly pager tests at 630pm on 154.160. :
The other thing is as Im in bay county, to get gratiot police I program in the saginaw towers frequency, 868.9875. Try that. I know fire has a talkgroup but hasnt been active. I dont listen or pay too much attention to gratiot I confess especially with bay county made the switch to difgital Im listening a lot to them.
Also see the recent thread - Gratiot co 800 mhz re band
Also at the gratiot page
Gratiot County, Michigan (MI) Scanner Frequencies and Radio Frequency Reference
*10/12 FCC App 0005474204 for County Fire: 159.405 Repeater with 155.13 (MOTOTRBO) at Breckenridge

Gratiot Co has not moved to the new re-banded freqs yet, however the radios have been updated to work on them, once the change has been made at the towers.
The control channel is still on 868.875 as of today. I don't know when the change will be made.

The 868.875 I just wonder .. could they have been getting interference from Standish tower thats is also cc 868.875? I know when I put that one in here I get the Standish tower, not gratiot.
154.160 just paged out a med call.

I have an indoor 3 element 800Mhz yagi pointed out a window, at the Gratiot Co tower and am receiving the control channel on 868.875 Mhz. I am in Merrill.

Breckenridge just had their pagers, and radios re-banded last night, unsure of the full transition to 800MHz though. Seems like as soon as Ashley, and any remaining departments have their radios rebanded, which should be pretty
soon, since a couple departments already use it. But thats me just speculating

Radios can't be rebanded. I assume you mean narrow banded, which has nothing to do with 800 or MPSCS.

Yes, I meant narrowbanding, my mistake.. But I think most of the departments are pretty much set for the transition. Im actually trying to get onto breckenridges fire dept, and thats what they were doing when I stopped into the hall last night, but from what Ive heard from them, they have mototrbo, which is something im not too familiar with

The other Gratiot Co thread mentions the possibility that Breckenridge is going to a MotoTRBO system, which cannot be monitored by scanners.
Gratiot co 800 mhz re band |

Which is weird to me that they would be the only district with mototrbo. I know mototrbo is a motorola system, and thats all I know, but what is the significance of it of they're the only ones (from what I've seen from the forums) getting that?

Just a guess is all, Maybe they coudnt find the money for the radios and going this route make the fcc happy to be narrow banded at a cheaper rate? Digital HT's run $4500-$500 a piece!
They might still do digital m sure 911 might want them to be able to talk to police and vice versa?

No, because analog HTs run $200-400 each. MotoTRBO is much more expensive. But they had grant money, so costs don't matter. |
