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 […]
