LOL...dedication! Both airports have an 0845 Hrs. daily radio test. Since yesterday was day one for O'Hare, the OCC made an announcement that all radios will be checked. Notepad was ready to go, and there you have it. Still more to go..if the city rigs receive O'Hare radios would be an example. In the past, surrounding companies were issued one "J Radio" for O'Hare incidents per company. Aviation Security hasn't migrated yet, as far as I can tell via Site-1. TMA's, Tow Trucks are a few others to watch for. My understanding is O'Hare Operations will be using the Tetra system that's being built out. They and the Motor Truck Drivers/Snowplows are using the UHF-T Trunking system, which they will have to abandon soon. Plenty of room on the trunking system too, time will tell.You are a beast at finding these! How are you determining which is what on the RIds? Just careful listening?
I updated the page to have headers so the table of contents renders as well
I just looked at the page, seems a little more cluttered that way, at least to me. Others might disagree but that's ok. The RID's are in there for anyone who wants to update.
