MF/HF Radiotelephone Your VHF radio is intended mainly for short range communications, generally 5-10 miles , and at least 20 miles to a USCG station.

Frequencies immediately below MF are denoted low frequency (LF), while the first band of higher frequencies is known as high frequency (HF) . MF is mostly used for AM radio broadcasting, navigational radio beacons, maritime ship-to-shore communication, and transoceanic air traffic control.

Digital selective calling or DSC is a standard for transmitting pre-defined digital messages via the medium-frequency (MF), high-frequency (HF) and very-high-frequency (VHF) maritime radio systems . It is a core part of the Global Maritime Distress Safety System (GMDSS).

The MF/HF has Digital Selective Calling (DSC*) as standard with a built in Class A 6CH DSC watch-keeping receiver. You can transmit and receive digital selective calls for quick and efficient establishment of distress, urgency, safety and routine communication with other ships and coast stations .
