Range

The mobile maritime radio service on border waves has a range of approx. 150 nm . The service thus represents an extension of the mobile maritime radio service to VHF .

Usage today

With the advent of the mobile maritime radio service via satellites , the importance of the maritime radio service on border waves has decreased significantly. However, due to the lack of guaranteed satellite coverage above the 70th parallel north or south by Inmarsat , the maritime radio service on border waves is the only safe way to communicate with other maritime radio stations outside of VHF maritime radio and without the problem of the dead zone when communicating via shortwave maritime radio , to get in touch.
