Emergency Communications
One of the best forms of communications that hams have at their disposal when forced to operate from challenging locations in regards to accessing distant repeaters is "Cross Band Repeat."
Cross band repeat is implemented using a dual band cross band repeat capable mobile transceiver, and a dual band HT. The repeater receives signals on one amateur radio band (for example 70 cm) and retransmits those signals on a second amateur band (2 meters). Thus the name "Cross Band Repeat."
The purpose of a cross band repeat system in your mobile is the same as any radio repeater. It allows stations to communicate that ordinarily would not be able to do so because of the distance to a repeater, or possibly because you are located in a reinforced concrete and steel building, where your VHF HT is not capable of reaching a distant repeater.
In a situation such as these, cross band repeat comes into its own.
