The road channel is the primary frequency, all trains monitor this channel, Defect detectors are on the Road channel as well.
To call the dispatcher, crews select the Dispatcher channel for the area they are in, 'Ring up' the dispatcher using DTMF codes, and await a reply on the dispatcher channel, and they will converse there.
Most CSX remote base stations (and many portable radios) will transmit a 250.3 Hz tone, to eliminate audio feedback in dispatching facilities, however all dispatcher/road channels operate in carrier squelch mode.
