No single event or station introduced radio broadcasting to the entire United States. Instead, broadcasting activities evolved in many locations, slowly entering the public consciousness. By early 1922 there was enough organized activity for various publications to begin putting together national lists of stations that were providing broadcasts intended for the general public. However, because of the scattered nature of the activities, no single list at this time, including this one, was able to keep up with all the stations on the air. (Also, note that the ranges listed for many of these stations appear to be very optimistic, even for optimum nighttime conditions).

The list below was prepared while U.S. broadcasting was going through an important transition. Initially there had been no restrictions on which radio stations could broadcast programs intended for the general public. But on December 1, 1921 the Bureau of Navigation issued a new regulation, which restricted non-government broadcasting to only those stations which held a Limited Commercial licence plus an authorization to use the Entertainment wavelength of 360 meters (833 kilohertz), and/or the Market and Weather wavelength of 485 meters (619 kilohertz). It took a few months for all the stations to fall in line with this new broadcast service regulation, which means that in the list below many stations from other licence categories are still included. However, these stations were now required to either get Limited Commercial licences or stop making broadcasts, which explains why some entries report that, due to the new restrictions, the stations were no longer making broadcasts. (A review of how you can determine a station's licence classification from its callsign is included at the close of this list).

Callsigns and Licence Classifications: Most of the stations listed above which have callsigns starting with K or W (WBT, KYW, WMH, WHK, KDKA etc.) held the Limited Commercial licences which, with the adoption of the December 1, 1921 broadcast service regulations, had become mandatory for private broadcasting stations. (Many of these stations had previously held licences in other classifications, especially Experimental and Amateur. Also, it was not uncommon for a station to hold more than one licence, and operate under different callsigns according to the licence classification it fell under at the time it was on the air).

Numerous stations in this list have callsigns that start with a number, which was the Radio Inspection District in which they were located, followed by two or three letters. Despite the similarity of their calls, these stations were actually divided among four different licence classifications, although what they did have in common was that, because of the December 1st regulations, they all were now required to get Limited Commercial licences if they wanted to continue to make broadcasts intended for the general public. Many stations in the above list had standard Amateur licences, which meant they normally transmitted on the congested wavelength of 200 meters (1500 kilohertz). The callsign rule for standard Amateur stations was that the letter following the district number could be anything except X, Y, or Z. Some of the better known standard Amateur stations appearing in the above list are 2IA in Jersey City, New Jersey, 1OJ in Pawtucket, Rhode Island, and 4CD in Atlanta, Georgia. The other three licence categories -- Experimental, Technical and Training School, and Special Amateur -- which had callsigns starting with district numbers were known collectively as the Special Land stations. These stations generally were allowed to transmit on the less congested wavelengths between 600 and 200 meters (500 to 1500 kilohertz). Experimental stations had callsigns with an X as the first letter following the district number. Some of the more prominent Experimental stations from this list include 2XJ in Deal Beach, New Jersey, 6XAC in Los Altos, California, 1XE in Medford Hillside, Massachusetts and 1XAD in Pawtucket, Rhode Island. Technical and Training School licences were most commonly issued to colleges and universities, and their callsigns had a Y immediately after the district number. Two Technical and Training School stations are included in this list -- 8YO, Columbus, Ohio (Ohio State University), and 9YY, Lincoln, Nebraska (University of Nebraska). Finally, Special Amateur licences allowed qualified amateurs to legally operate on the less congested wavelengths, and their calls had a Z after the district number. The two Special Amateur stations in this list are 9ZAF in Denver, Colorado, and 3ZO in Parkesburg, Pennsylvania.

A few U.S. Government stations are also listed. (Government stations were exempt from the private station requirement that broadcast stations have Limited Commercial licences). Stations operated by the U.S. Navy were assigned calls starting with N, including NOF in Anacostia, D.C. The U.S. Army stations were supposed to use calls starting with WUA to WVZ and WXA to WZZ, hence Fort Wood's WVP in New York Harbor. However, other Army stations at this time seem to have used whatever calls they wanted, such as Fairfield, Ohio's WL2. Finally, there is one ship station mentioned in this list. The entry for 2XJ in Deal Beach, New Jersey refers to KDOW, which was the S.S. America.

Additional Information: The various land station licence classifications are defined in the August 15, 1919 edition of Radio Communication Laws of the United States, beginning with regulation 51. For a detailed review of U.S. callsign practices, see United States Callsign Policies. For a comprehensive overview of the establishment of the Limited Commercial broadcast service and the current status of many of the stations listed above, see United States Pioneer Broadcast Service Stations. And for more information on radio station lists, see Early Radio Station Lists Issued by the U.S. Government.
