Welcome to the Supreme Radio Communications (Bloomington) collaboration article, a Trunked Radio System located in McLean County, Illinois, United States.
This is where you, the user, may index any articles you develop for scanning related topics for this Trunked Radio System.

The Supreme LTR system in Bloomington is an LTR Standard. The LTR Passport portion no longer is in use. The system originally utilized four 454 Mhz frequencies (see below) but those are no longer used. There is some conventional repeater usage of their licensed frequencies two.


LTR Frequencies

  • a listener reports that on 460.850 he heard LTR Traffic on 0-09-01x (possibly 011), then heard CWID and GRE Detected HR:09.

LTR Passport Frequencies
The frequencies formerly part of the Passport system are listed below. There are no longer the 2-second repeater clicks on any of these and some are now part of the Capacity Plus system (see below).

  • 460.850
  • 461.4625
  • 461.7625
  • 462.1500 (now part of the Capacity Plus system)
  • 461.1500 (now part of the Capacity Plus system)
  • 463.2375 (now part of the Capacity Plus system)

New Capacity Plus System
Some of the frequencies have switched to the new Supreme Capacity Plus system. The data beacon channel rotates and has been heard on the following frequencies

  • 461.1500 data clicks every 2 seconds
  • 462.1500 TRBO data heard
  • 463.2375 data clicks every 2 seconds

Other Notes:
These frequencies are licensed to the same company and could be part of the either the LTR or LTR Passport. It is doubtful though since none of these frequencies have the LTR 15 second or 2 second idle bursts (although not all LTR systems have the bursts turned on).
