Coast radio stations, medical and quarantine services, general regulations, etc.

General Information

The following details apply to all volumes of the List of Radio Signals.

Frequency: 500. A2. 2 kW. signifies Wave Frequency 500 kilocycles per second, Type A2, Power 2 kilowatts.

Times quoted are, unless otherwise stated, in Greenwich Mean Time (Civil) (G.M.T.) and the hours are reckoned from 0000 (midnight) to 2359..

Bearings are true, expressed in degrees from 000° (North) to 359°, measured clockwise.

Geographical Positions of coast stations are normally as given by the controlling authority; in some cases they are in accordance with the Admiralty chart. Coast stations are shown on Chart No. 3778 (Telegraph Chart of the World). If bearings are taken to coast stations it should be remembered that in many cases the positions quoted are only approximate.

Service Details Great Britain Coast Radio Stations: General Remarks

With the exception of Portishead and Rugby (to which special arrangements apply), the following remarks apply to all coast stations in Britain.

1. Ships are normally included in traffic lists only during their notified hours of watch. They may be called at other times, however, if the coast station has reason to believe that they are within range and keeping watch. Ships whose notified hours of watch do not coincide with times at which traffic lists are trans­mitted are called during their notified hours of watch.

This list comprises the Call Signs of all Coast Radio Stations of which service details are given in this volume.

Call Signs	Station	Call Signs	Station
AMD	Barcelona	CNP2	Casablanca Port...
ASC	Chittagong	CNP3	Fedela Port
ASK	Karachi	CNW	Tanger
		CQA	Mindelo
		CQD	Praia
CCA	Arica	CQM	Bissau
CCE	Valparaiso	CQO	Bolama

2. Stations keep loud-speaker watch on 2,182 kc/s at all times except when engaged in exchanging traffic. Calls received on 2,182 kc/s are answered on that frequency.

3. During a period of distress, the frequency of 512 kc/s may be used by a ship to call any coast station which is not engaged in the distress working.

The coast station will answer the call on its normal working frequency and, when communication has been established, the ship should transfer to its working frequency for the transmission of the traffic to the coast station.
