Crossband is a method of sending signals
from one radio frequency
to another by retransmitting the signal. In Amateur Radio
, for example, someone can set up a crossband repeater to send 2-meter
signals over the 10-meter
HF bands for long-distance communications.
There are several requirements for operating crossband. The person doing the retransmitting must have an FCC license that includes HF priveleges, and they must also act as a control operator. They are responsible for any illegal retransmissions, such as when some jerk gets on a 2-meter radio and spouts obscenities. While the jerk is responsible for the initial outburst, the control operator must kill the signal to remain legal. Additionally, the control operator must identify their radio license identification at least every ten minutes.
