LOGS

7.31 Station logs. Each licensee of coastal stations shall maintain an accurate log of the operation of each station on the international calling and distress frequency 500 kilocycles (410 kilocycles on the Great Lakes), as follows:

(a) At stations where continuous watch is maintained an entry shall be made at least every 15 minutes. At stations having limited hours of operation, similar entry shall be made during the time the station is active. All calls or answers made shall be entered, giving time and call letters of station worked. Stations may be designated by their call letters in all log entries.

(b) Entry shall be made of any unlawful interference from other stations.

(c) Distress calls and any unusual and special incidents shall be duly entered.

(d) Notations shall be made of any break-down of apparatus, failure of power supply, noises or disturbances tending to delay traffic.

(e) When a change in the watch is made the operator relieved shall sign his name with the indication "off watch" and the relieving operator shall sign his name showing that he is "on watch."

(f) Each sheet of the log shall be numbered and dated. The time used for making an entry in the radio log shall be expressed in conformity with European practice in four figures, starting at midnight of the time at the meridian of Greenwich, that is, 12:01 . m. is to be shown as "0001"; 1:00 a. m. as "0100"; 1:00 p. m. as "1300"; 6:30 p.m. as "1830"; 12:00 midnight as "2400"; etc. (This method of expression is equivalent to that denominated in this country as Greenwich Civil Time). The abbreviation "GMT" shall be stated at the heading of the column in which the time is entered.* (Sec. 4 (i), 48 Stat. 1068; 47 U.S.C. 154 (i)) [Rule 273, as amended Oct. 24, 1934]

SUBPART-MARINE RELAY STATIONS

DEFINITIONS

7.41 Marine relay service. The term "marine relay service" means a radiotelegraph service carried on between marine relay stations communicating with one another for the relay of maritime mobile communications or for the interchange of messages or operating signals pertaining to maritime mobile communications only.** [Rule 276] 7.42 Marine relay station. The term "marine relay station" means a coastal telegraph station licensed to communicate with other coastal telegraph stations within the same geographical area.*† [Rule 277]

OPERATION

7.61 Limitations as to licenses and use of frequencies. A license for marine relay service will be granted only to a licensee of a public coastal telegraph station and only to the following:

(a) A coastal telegraph station licensee, for the transmission of radio operating signals utilizing the coastal calling or individual working frequencies that are licensed to the same applicant at the particular location where marine relay service is desired.

(b) A Great Lakes coastal telegraph station licensee, for the relay of messages either destined to or originating at mobile stations on the Great Lakes, Provided, however, That such messages shall be relayed only upon the coastal working frequencies that are licensed to the same applicant at the particular location where marine relay service is desired and provided further that the frequencies are available for both fixed and mobile services under the provisions of the International Radiotelegraph Convention.

(c) Any other coastal telegraph station licensee, for the relay via another marine relay station of messages destined to a mobile station, Provided, however, That such messages shall be relayed only upon the coastal working frequencies that are licensed to the same applicant at the particular location where marine relay service is desired, And provided further, That this service is not to be used for the normal routing of traffic, but only when, for any reason, the initial coastal station has been unable to communicate directly with such mobile station.*† [Rule 278]

7.62 Points of communication. Marine relay stations are permitted to communicate only with stations of their own class located in the same geographical area, provided, however, that they may also communicate with foreign coastal stations within their geographical areas if no interference with international service results from such communication. The areas to be designated in licenses, unless otherwise specified, will be as follows:

(a) Atlantic-Gulf area.

(b) Great Lakes area.

(c) Pacific area.*+ [Rule 279]

7.63 Station logs. Each licensee shall maintain adequate records of the operation of each station, including (a) hours of operation, (b)

frequencies used, (c) points of communication, and (d) estimate of the total volume of traffic transmitted for the periods of time covered. This information shall be made available upon request by authorized Government representatives.*† [Rule 280]
