Good morning all
This thread is for discussion relating to the Chicago NASCAR Street race event running from July 1 to July 2

Information on what channels are being used and what they are being used for et cetera would be appreciated.
A reminder though. Please don’t post any, sensitive or real-time information on the actual happenings in the race.
Thanks.

okay
FYI.
It looks like citywide five is being used by traffic posts, and everyone else is on event one.
Not 100% sure, but that’s what I’m gathering.
If anyone can clarify or correct me on that, i’d appreciate it.

Currious what radio system is setup for the facilities-local track use. Trbo?
No I don't mean the nascar specific system. I mean security etc. Last time Chicagoland Speedway was used they had a temp trbo trunk system by Comm Direct.

I'd predict a Mototrbo Cap system or one of the Radio dealers like Com that have a site close to the area. Maybe the same system Lola uses. Kevin do u know lol?

Just for some information
7510.
All of the bike teams are now switching over to event one instead of citywide five.
To be honest, I don’t think it will last long though, as there is a lot of communication between event one dispatch and citywide five dispatch which is actually hindering the communications of the officers.
I don’t understand why they just didn’t keep it all to one frequency.
Apparently the units inside the perimeter are on event one and the units outside are on citywide 5
A bit stupid if you ask me from a public safety communication standpoint

Milwaukee Region Scca is a sports car series that mainly runs at Mile or RoadAmerica.

Sorry for the (too) late reply. I did catch a driver talking to his pit crew on 466.500 (D047) re: handling issues he was having during his practice run. I was not able to detect any DMR trunked system used at the race similar to what I've heard used for Lollapalooza, etc., and found no STA licenses that would handle the number of radios that would have been used for an event of this size.

463.9250 CC11 ?

Today I observed the following for the Communications Direct Cap+ system. 451.5375 was confirmed as CC9. I also saw 452.4875 briefly pop up with CC14 but heard no voice traffic.

This would appear to set up the following possible pattern:

451.4375 CC8
451.5375 CC9
451.6375 CC10
451.9625 CC11
452.1375 CC12
452.2875 CC13(?)
452.4875 CC14(?)
452.6875 CC15

The traffic on 463.925 CC11 was encrypted with RIDs not matching the ones (3xxx, 4xxx and 7xxx-series RIDs so far) on the above freqs. Even though that freq is covered by this this license, that repeater appears to not be part of this system. Other freqs covered by this license are 464.325, 464.600 and 464.8875. In my limited listening time this evening, I did not detect system traffic on those freqs.

On a whim, I programmed a Cap+ system into my SDS100 with the above eight freqs in LCN order (1-8) matching the color code order. Even though there wasn't much traffic on the system, I did receive a handful of talkgroup 102 (security?) and 107 transmissions on 451.9625 CC11, which seems to at least indicate that this is LCN4.

Finally, I confirmed the additional talkgroups active on this system:

123, 125, 127, 131 (user calling for "medical") and 132.

Hope this helps...

In looking at my notes, all but one of the freqs for Communications Direct NASCAR Street Race Cap+ systems (WSDK913) match what has been used for Lollapalooza since 2018:

450 System -
LCN1 451.4375 CC8
LCN2 451.5375 CC9
LCN3 451.6375 CC10
LCN4 451.9625 CC11
LCN5 452.1375 CC12
LCN6 452.2875 CC13
LCN7 452.4875 CC14
LCN8 452.6875 CC15

460 System -
LCN1 464.8875 CC3 (has been 464.900 previously)
LCN2 463.925 CC5
LCN3 464.600 CC7
LCN4 464.325 CC9

The freqs I have not heard system activity on this afternoon have been 452.2875, 452.4875, and the 460 freqs. All of the other 450 freqs have been active programmed as a Cap+ system and tracking properly when using the above settings. TG 136 is new today.
