Notice to Mariners No. 4 of 1953

OFFICIAL MESSAGES TO BRITISH MERCHANT SHIPS AND FISHING-VESSELS

THIS organization provides for the transmission of important messages from Naval Authorities to small ships, trawlers, &c., fitted with radio-telephony, on occasions when such messages may be of vital importance to their safety and welfare. Tests of the organization, lasting for one week, may be held at irregular intervals without prior notice, and all small craft fitted with R/T apparatus are earnestly requested to listen for the messages broadcast during these tests and to forward particulars of those received.

NOTE.—This notice will in future be issued annually as New Zealand Notice to Mariners.

2. When the organization described in this Notice to Mariners is ordered to be brought into force—

(a) Ships are to continue to read the traffic from the coast station serving the waters in which they are sailing. Official messages will be broadcast as shown in the table below :

(b) T.R.s are to be discontinued :

(c) Messages are not to be acknowledged unless ships are specially directed to do so in the text of the message :

(d) Ships are to conform to any restrictions regarding the use of radio which may be issued by the Naval Authorities.

New Zealand Coastal Waters

These messages are to be broadcast at definite times from the radio-stations given in the following table. Normal R/T procedure to which small ships are accustomed is employed as far as possible. A preliminary call will be made on 2182 kc/s. and the messages will then be broadcast on the coast station’s working frequency of 2162 kc/s. ; this frequency will be referred to in the preliminary call. The text of each message indicates the Naval Authority who has originated it and contains, if necessary, details of the locality to which it refers.

Example.—The shore station calls on 2182 kc/s. “Hullo, all British merchant ships, this is Wellington Radio. I have a message from the New Zealand Naval Board. Please listen on 2162 kc/s.”

The shore station then changes frequency and proceeds : “Hullo, all British merchant ships, this is Wellington Radio. Here is a message from the New Zealand Naval Board. Begins. The organization for broadcasting official messages for ships fitted with radio-telephony given in N. to M. No. 4 is now in force for test for one week ending . . . . (repetition of text) . . . (date time group) . . . ends.”

All ships hearing these messages, when transmitted for test purposes only, are particularly requested to forward brief reports through their owners to the Navy Department and the Marine Department, Wellington, stating the times and their approximate position when these test messages were heard.

R/T Broadcast Routines

• In all cases official messages will be transmitted prior to the weather report and navigational warnings scheduled for the above times.
