IC02AT.6 TRANSCEIVER TRANSMIT UNLOCK (FINAL PART) (IC-O2AT, IC-O4AT, IC-751, IC-720 Of course, in an emergency, anyone may use any type of frequency to attract attention. The emergency must be life- threatening or pertain to "immediate protection of property" before one would resort to using frequencies outside of the ham band. For mariners, the United States Coast Guard works closely with the high seas marine radio telephone service that is easily accessed via a geral coverage ham set modified to transmit on general coverage marine telephone channels at 4, 6, 12, 16, and 22 MHz. However, using ham radio equipment on telephone channels for routine phone calls is not allowed. Even though you may have a ship radio telephone license that allows you the use of marine telephone channels the license only allows Part 81 and Part 83 type-accepted equipment to be used for transmitting purposes - and again, Amaeur Radios don't meet this type acceptance. Let me put it bluntly - if you get caught using ham radio equipment on frequencies that you're not authorized to use, you could lose your license and might also face stiff fine or imprisonment. Before even contemplating making any modification to your equipment, weigh carefully the consequences of operating on frequencies outside of your license category. CONTINUED IN FILE IC02AT.8
