Digital Selective Call (DSC)

DSC is, basically, a paging system that is used to automate distress alerts sent over terrestrial (i.e.: non-satellite) VHF, MF and HF marine radio systems. The DSC system’s digital processing techniques, combined with the relatively narrow receiver bandwidths used, provide a DSC signal with resistance to noise and fading over the radio path. This result […]

MF/HF RT radio is often called an SSB radio. It is a transmitting-receiving system often referred to as a Transceiver (Tx/Rx), which allows the operator to either transmit or receive information by voice. MF/HF radios use SSB (single sideband) modulation for voice communication. The same set may also be used NBDP (Narrow Band Direct Printing) communication, also called TELEX. MF/HF radios […]
