150W & 250W MF/HF Digital SSB Radio Telephone

150W & 250W MF/HF Digital SSB Radio Telephone

This is an MF/HF SSB (single side band) radiotelephone with a built-in DSC/watch receiver. The built-in DSC/watch receiver produces and receives digital selective calls for quick and efficient establishment of distress, urgency, safety and routine communications with other ships and coast stations than install any MH/HF DSC facilities. Data is displayed on a large, easy-to-read backlit LCD. Operation is simplified by the use of few keys and easy-to-follow menus. Besides, an NBDP (narrow band direct printing) Terminal Unit is optionally available.
