Radio Service Bulletins were issued monthly by the Bureau of Navigation (and later the Radio Division, Department of Commerce) from January 1915 into the 1930s and beyond to keep mariners, aviators, radio listeners, and others abreast of developments in the new medium of radio.  Radio was used for radiotelegraphy, ship-to-shore, and ship-to-ship communications, and increasingly as the 1920s and 1930s advanced, broadcasting.  The bulletins reproduced here offer a snapshot of the state of the radio art during these years. 

Bulletins issued before 1921 are primarily concerned with radiotelegraphy communications between ships although there are some references to land stations too.  Present-day readers should keep in mind that these bulletins were intended for the use of radio operators who needed to contact other ships or shore stations to relay messages.  As such, the bulletins frequently list radio-equipped ships as well as rates for radiotelegraph and radiotelephone messages.  The bulletins also refer to weather, time, and ice warning stations, and occasional information such as warnings about areas that may contain explosive mines (after World War I).  After 1921, the bulletins increasingly refer to early pioneer broadcast stations, some of which still exist today (although generally on different frequencies and at different power levels than initially authorized).  Notice that many call letters presently used by broadcasters today were once assigned to radio stations aboard ships.

The August 31, 1931, edition of the Radio Service Bulletins contained an index to orders of the Federal Radio Commission that were published in the RSB up to that date.  For your convenience, this index (Index of General Orders of the Federal Radio Commission as Published in the Radio Service Bulletins) has been extracted and is available separately as a PDF document.  Similarly, the August 31, 1931 edition also included a helpful list of items appearing in the Radio Service Bulletins over the previous decade, under the heading Index of Regulations and Miscellaneous Articles Appearing in the Radio Service Bulletin, Years 1920 to 1931

The continuous series of 183 bulletins (in PDF format) available here starts with No. 1 / January 1915.  Note that no bulletins were issued from April 1917 until August 1919 because of World War I.   Bulletins were issued up to 1952, but bulletins after June 1932 are not available here.
