The Inland Waterways is a radio application of mobile services, or the land mobile service . It is used for radio communication in inland shipping in the frequency range of 156.025 - 162.025 MHz

Radio operating certificate

The regional agreement on inland navigation stipulates that the VHF radiotelephone certificate for inland navigation is required in order to be allowed to operate a ship or land radio station, provided that one does not have a radio operating certificate issued before 2003 that includes authorization for inland navigation. In addition, numbers must be assigned by the BNetzA ( frequency allocation certificate until June 1, 2013 ) and a radio system approved for inland navigation is required.

ATIS

Corresponding radio devices are required in inland shipping radio, which transmit an ATIS identifier after each transmission . This ATIS signal can then be made visible by radio stations on a reception display and consists of a country code and the coded call sign of the ship's radio station. In this way, the identity of the transmitting radio station is displayed for each transmission . In the radio traffic circles ship-to-ship, ship-port authority and radio traffic on board, only 0.5 to 1 watt may be transmitted, the radio devices must automatically reduce the transmission power on these channels.

Differences to marine radio

A major difference to marine radio is that there is no uniform " emergency and call channel ". In the event of an emergency , in accordance with the Inland Waterways Radio Manual, it is preferable first

  1. Call the Revierzentrale with 25 watts (the corresponding radio channel of the traffic circle nautical information can be found in the manual for inland waterway radio, regional part) with a MAYDAY radio message in order to initiate aid or rescue operations on the part of the authorities , then depending on the situation
  2. on channel 10 (general ship-to-ship channel) with max. A second 1 Watt MAYDAY - radio message depose to help the shipping industry to request and the surrounding maritime warning.

Handheld radios

It is important for sport boaters that the use of handheld radios is only permitted in the "radio traffic on board" (channels 15 and 17); this in turn is not permitted on small vehicles. These devices may therefore only be used on small vehicles for marine radio traffic, but not for inland waterway radio. Small vehicles from authorities and organizations with security tasks are excluded.

This rule applies to Germany. In other countries, such as B. the Netherlands , handheld radios may also be used in domestic radio.
