It provides immediate comunication between engine room and bridge for exemple for speed or direction of trusts.
Important function is the "public address system" oprated for alarms in case of emergency, or fire on board.
Internal comunication are also mede up with radio telephony (RT) with VHF.]]> 2018-11-21 16:44:22 UTC https://padlet.com/ciprex/w1hwokjhg16g/wish/306792249 ciprex https://padlet.com/ciprex/w1hwokjhg16g/wish/306794544 It opeates worldwide and be available to all ships and maritime countries.

Channel 16 is for distress.
Channel 13, 15, 17 is for internal comunication.
Channel 70 is for digital selective calling (DSC).]]> 2018-11-21 16:51:58 UTC https://padlet.com/ciprex/w1hwokjhg16g/wish/306794544 ciprex https://padlet.com/ciprex/w1hwokjhg16g/wish/306797110 All ship must have a call sign that is made up of letters and numbers and it's unuque for each ship.

For latitude and longitude are used degrees, minutes (and decimal of minutes if necessery).
For bearing and distance for a point of a fixed object. The bearing is given in 360 degreesnotation from the true north and the distance in miles
2. Bearings are spoken in 360 degrees notation from the true north or from the vassel's bow
3. Courses are expressed in 360 degrees notation from the true north
4. Distances are expressed in miles
5. Speeds should be expressed in knots
6. Times are expressed in 24 hours UTC notation]]> 2018-11-21 17:37:01 UTC https://padlet.com/ciprex/w1hwokjhg16g/wish/306807210 ciprex https://padlet.com/ciprex/w1hwokjhg16g/wish/306809744 When you speak over the radio you must speak clearly and slowly, not shout because causes distortion, tell in full the phrase and answere in full the phrase. contracted forms are avoided and also may/might/should/could.
