* Where as a regular repeater always listens to the same frequency (the input of the repeater) and always transmits on the other (the output), a crossband repeater transmits on one frequency whatever it hears on the other, whichever it hears first. | * Where as a regular repeater always listens to the same frequency (the input of the repeater) and always transmits on the other (the output), a crossband repeater transmits on one frequency whatever it hears on the other, whichever it hears first. | ||
