Cross-Band Racon: A racon which transmits at a frequency not within the marine radar frequency band. To be able to use this type of racon, the ship's radar receiver must be capable of being tuned to the frequency of the cross-band racon or special accessory equipment is required. In either case, the radarscope will be blank except for the racon signal. See in-band racon.
