Found this in FCC database. Although the license gives no emission codes so its hard to tell what it could be. That may not be what your hearing but that was the only license that popped up for Peoria IL. ULS License - Paging and Radiotelephone License - WQCE738 - Supreme Radio Communications, Inc. - Frequencies Summary
Thank you for finding that. I can now add 454.575 with it. I dont know if that is it or not.Good evening I am picking up some unknown freqs that are DMR on UHF. The freqs are: 454.025,454.0875,454.300,454.6375. Could someone decode it and fiqure out who it is. Please.
