Short Vid showing how the I-Bus radio system works radio 1 is tuned into a control data channel (140.26875 Mhz) and radio 2 is tuned into 2 local voice channels 1.(140.4125 and 2.(140.2875) .... you can see data being sent through the control channel telling the I-bus radio sets (either group or 1 to 1) to switch to whatever channel is selected by the system.... if the system is busy radio sets are told to "WAIT" untill a free channel comes up. calls are started by either ..Driver, Base, Or Centercomm.
