500 kc/s (600 metres)—at any time.

4. A list of the stations included in the organization showing the areas for which they will transmit and the waves on which messages will be broadcast is shown in the Schedule. As far as possible the times 0400 and 1600 G.M.T. have been fixed for transmissions from stations under paragraph 3 (c) above, since, in all areas of the world, one or other of these times will fall within a period when ships with one operator are keeping watch. Times at which messages will be broadcast from 500 kc/s (600 metres) stations are not included in the Schedule, since merchant ships keep normal watch on this wave and messages may, therefore, be broadcast from these stations at any time. Messages broadcast outside single operator periods will, for the benefit of ships with one operator, be repeated at the commencement of the next following single operator period.

5. Messages containing information affecting British merchant ships will be broadcast :—
   (a) By Admiralty to all British merchant ships in all areas ;
   (b) By Admiralty to British merchant ships in any particular area or areas ;
   (c) By Naval Authorities abroad to British merchant ships in the areas for which they are responsible.

Messages under (a) will be broadcast from Rugby and Falklands with the call sign GBMS, and will also be broadcast with the same call sign by the W/T stations concerned shown in column 3 of the Schedule. (Messages under (a), during “ test ” periods, will be broadcast from Rugby and Falklands only.)

Messages under (b) will be broadcast from Rugby and, if necessary, from Falklands, with the call sign or call signs for merchant ships in the particular area or areas concerned. They will also be broadcast by the W/T stations of the areas or area concerned, using the appropriate call sign.

Messages under (c) will be broadcast by the W/T stations shown in column 3 of the Schedule, using the call sign for merchant ships in that area (vide paragraph 2 above). Such messages may also be broadcast from Rugby and/or Falklands with the same call sign.

6. The W/T stations broadcasting messages will use their own call signs and will indicate the Naval Authority originating the message at the beginning of the text. For example, a message broadcast by Aden W/T station from Commander-in-Chief, East Indies, for merchant ships in Area 3 : CT GBMS 3 GBMS 3 GBMS 3 DE GZQ GZQ GZQ BT from Commander-in-Chief, East Indies, BT. During the period 1st March to 30th April, 1926, H.M. ships engaged in the prevention of smuggling arms will be operating without lights in the Persian Gulf BT 1030 () BT Repetition BT from Commander-in-Chief, &c., &c., BT 1030 () AR VA.

NOTE.—(*) This is G.M.T. at which the message was ordered to be sent. It may be followed by the date, thus : “ 1030 NR 15 NR 2.”

7. The procedure outlined in this organization is not intended to interfere with or replace existing arrangements for broadcasting to merchant ships messages concerning navigational dangers, weather reports, or gale warnings. Where routine arrangements exist for broadcasting such messages, those arrangements will continue in force.
