Bridge Unit ID® (option)
In response to the critical disruption of radio communications that can occur when more than one "bridge" device links radios with identical frequencies, causing heterodyning, C-AT has developed the Bridge Unit ID for the ICRIs.
The “announcement” radically simplify the task of locating the owner of the interfering bridge and in shutting the device down.
The Bridge Unit ID is a digitized speech message selected by the user organization / agency. The “ID” is transmitted when the ICRI is first powered up on all talk groups, and then at preset intervals of 0, 5, 10, or 15 minutes.
The announcement automatically “skips” a broadcast if there is any radio activity at the interval mark.

Problem: Ability of radio used by Recon Commander to receive signals from assigned radio frequency used by his Entry Team is substantially reduced when another in-band radio is “keyed” by LE Commander transmitting to his Entry Team personnel.
Cause: The closer LE Commander is to Recon Commander, the more severe the “desensing” of the Recon Cmdr’s radio. The less the frequency separation between radios “A” and “B”, the more severe the desensing will be.
