Whenever you are buying a device that utilizes broadcast frequencies and communication, you should always double check with the Federal Communications Commission (FCC) to ensure that a license is either needed or not needed. The same goes for marine radios but do not worry, we have already done that step for you. According to the FCC, a license is not required to use marine VHF radios or any types of radar, GPS, or LORAN receivers. However, ships that use an MF/SF single side-band radio must be licensed by the FCC.
Now, it is important to note that some work is required on your part for radios with DSC capability. Before you transmit using the DSC function, you must obtain a nine-digit maritime mobile service identity number. This number must be programmed into your unit before you use it.
