Why can't I transmit on channels 16 through 22?

Rugged Radios has gone to great lengths to license a variety of frequencies for its customers. Channels 16-22, however, have been previously licensed by other businesses, organizations, or government entities. Rugged Radios has provided these as Listen-Only channels for recreational use. This eliminates the possibility of our customers transmitting on those frequencies and causing radio traffic problems for those entities when they need communication the most.
