Right now they're in the middle of switching over and some talkgroups are still on the old ID's and some are on the new type II ID's so good luck trying to listen. As of this morning (Sat Nov. 6) I am still hearing the entire PD on the old ID's. SO patrol and the small town PD's that work off fleet 4 are still on the old ID's while airport security and civil are on the new ID's. The lafayette fire dept is on their convention backup channel of 14-RP (855.4625) while their radios are being reprogrammed and the volunteer departments are on the new fleet 3 ID's. I am using a few different scanners some with the old ID's and some with new to monitor right now.
To listen to the old ID's you will need a fleet map, but like Milf said above, once they are exclusively on the new ID's you will not need one because the new ID's are all type II. South 300 said that they will all be switched over by Nov. 15.
