I am seeing now 30101 & 30107 also active on the Lincoln tower.

Hey Matt, I saw those talkgroups active yesterday on the Niagara Falls tower too! However, I believe that 30100, 30101, 30103, and 30107 are all a part of the same organization/company. The reason I believe this is because they are all using MOTOTRBO's enhanced encryption with Key ID 4. There's also Radio IDs in the same range being used on each talkgroup mentioned.

Talkgroup ID	Radio ID Ranges
30100	35xx
30101	34xx, 35xx, 36xx
30103	35xx, 36xx
30107	34xx, 35xx, 36xx, 11000

2026/01/29  13:28:10  Freq=420.675000  DCC=0  RAS  Enc Group call; TG=30100  RID=3580 [IMT BASE]  Ch=112  Alg=EP/RC4  KeyID=4  3s
2026/01/29  13:28:21  Freq=420.062500  DCC=0  RAS  Enc Group call; TG=30101  RID=3482 [2114]  Ch=112  Alg=EP/RC4  KeyID=4  5s
2026/01/29  13:34:12  Freq=420.675000  DCC=0  RAS  Enc Group call; TG=30103  RID=3631  Ch=112  Alg=EP/RC4  KeyID=4  2s
2026/01/29  14:03:02  Freq=420.062500  DCC=0  RAS  Enc Group call; TG=30107  RID=3464 [1629]  Ch=112  Alg=EP/RC4  KeyID=4  3s

Last important note... I've looked through my logs, and although the Radio IDs are in the same ranges with the exception of that one oddball 11000, I can confirm that none of these radios affiliated or switched to multiple talkgroups. They all remained one channel.

This is why so much effort goes into logging encrypted TG and KID combinations as well as associated RIDs. Once one TG is identified the other related ones fall into place.

So today I checked and I am getting 30100, 101, 103 & 107 but not showing enc for me on the Lincoln tower but it looks like 30101 is the busiest out of the 4.

I just right now turned my SDR back onto that system. I will be listening for the next few hours to see if I can pick anything up. From Niagara Falls I cannot hear the Lincoln tower. But I am also wondering since you're from Hamilton if you're not getting all the packets?

A lot of the 34xx and 35xx radios started to affiliate back-to-back with the system. I can also agree with what Matt said earlier that TG=30100 seems to be the most active one. Since starting to log the system today, I've picked up 13 radios on that talkgroup.

However, as we can see on the screenshot below, TG=30107 is still using EP/RC4 encryption with KeyID=4. You will also notice that there's a couple of Alg=BP... but I can almost guarantee those are bad decodes.

I am not sure... I am seeing 30102 now being used also on the Lincoln tower.. but 30101 out of those 5 it is still being used the most on the Lincoln tower.. 100 has 9 hits, 101 has 42 hits, 102 has 2 hits, 103 has 2 hits and 107 has 6 hits.

I will go back to monitoring in a couple days. I did find a new Capacity Plus system down here in Niagara Falls that I am working on decoding. Not sure who's on it... sounds like some kind of attraction/security/operations. Without hijacking this thread, I will share more information once I have it.

A bunch more new tg's showing up on the Lincoln tower now.

30100 (15 hits), 30101 (21 hits), 30102 (50 hits), 30103 (4 hits), 30104 (1 hit), 30106 (7 hits), 30107 (2 hits), 30111 (3 hits).

Now that the school buses are parked and off the air, I'm seeing a lot of 30102 and also private calls on the system.

On Sunday there was only 3 talkgroups active on the Lincoln tower, 30101 and 30102 had the most activity while 30100 has I think only had like 2 hits. So whoever 101 and 102 are they work on the weekends as well.

It seems that Switzer-Carty is not that busy compared to when Dunn The Mover owned the company. I only live two miles from the old Dunn The Mover's building.
