What is MF HF radiotelephone?
MF/HF radio station is a high tech equipment, designed for receiving and transmitting messages between vessels in the medium and high frequency range. It usually consists of a transceiver, a control block, and an antenna.
What is the range of MF HF?
MF/HF Radio Waves A reliable range of more than 150 nautical miles can be expected in most areas in the daytime, more in the nighttime. The high frequency range 4 – 30 MHz can provide communication for hundreds or even thousands of nautical miles. The long range is achieved by sky waves reflected from the ionosphere.

What is SSB MF HF?
MF/HF RT radio is often known as 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 modulation for voice communication.
