7411DPS - St. Clair County

[firephotographer50]

Hello Everyone. A friend of mine is on the Kimball Township Fire Department (St. Clair County) and they have a short range on scene frequency that they use. All he knows is the alpha tag they turn to on their radios "7411DPS" of which they usually just say "all units switch to DPS". They don't use it very often, but usually for training and working in large commercial structures where the MPSCS TGs sometimes don't work. Does anyone here have more information on this frequency? The actual freq., tone and mode? I'm not seeing it anywhere in the RR database. I know it is not a TG on the MPSCS as one time they sent a single unit to check on an alarm at the airport. The unit wanted to switch to DPS and the chief came over and said not to switch to it as their base would not be able to hear them. Thanks.

Maybe one of the NPSPAC interop 700 or 800 frequencies with a different label?

I had thought about that as all of the other departments in the county use all five of the 800 MHz National M/A channels ( 8CALL90/90D, etc.). Though the freqs have been updated in their radios they all still say "switch to I-TAC ___". But it doesn't make sense to me that one department would have a completely different alpha tag for a single frequency in that set. Many years ago, when St. Clair County first made the switch to MPSCS, Kimball kept their private frequency of 155.175 as an extra talk-around for a while. Looking at the FCC license list I see that it expired. I only see the old County Fire Dispatch 154.3700 which multiple departments still have licenses for until 2024. FCC Licenses and Scanner Frequencies for St. Clair County, Michigan (MI) Are there departments out there (anywhere in the US) that use the National Interop channels with different alpha tags? I would have thought that the tags would have to be standardized so different departments would know what channel to turn to in a mutual aid situation.

Does your friend take this radio that he uses on this 7411dps if so you could do a close call or freq counter to catch it

It's a paid-on-call department, so I would assume he has a radio assigned to him that he takes home. I don't get to see him that often in person because of our schedules, but I'll reach out to him and see if he would be willing to let me do a close call to try and catch it. Thanks for the idea. I never use the CC feature on my scanners, so I forget about trying it.

only being a tourist, but isn't 74 the County
so maybe it is a TG 11DPS ? [I did see something similar in the DB for another county]

Something that Dispatch doesn't have ?

That's correct. 74 = St.Clair County 11= Kimball Township and DPS I'm assuming is department of public services.

Yes, I've seen them simply relabeled as "Direct 1", "Direct 2", etc.. I've even seen a regional mutual aid TG relabeled as a TG that has never existed, just because FFs would be able to find that name in their radios when they were scrolling channels.
