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. (It is interesting to note that while a headline refers to this article as a "complete list of broadcasting stations", the text includes the author's "doubt if it contains twenty-five per cent" of the broadcasts that were on the air).

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. (A review of how you can determine a station's licence classification from its callsign is included at the close of this list).

What  Anyone  Can  Hear
Complete  List  of  Broadcasting  Stations  in  U.S.
By  ARMSTRONG  PERRY

THE present article by Mr. Perry is one of the most important because it gives a complete list of all the present broadcasting stations throughout the country. Things are moving so rapidly in Radio of late that it becomes almost impossible to keep up with the trend.
    It is of course no news to anyone that at present Radio companies, be they manufacturers, dealers, or jobbers, are springing up by the dozen over night; but it will come as a surprise to even the wise ones that there are now over seventy broadcasting radio telephone stations throughout the country, and new ones are being added almost every week. It seems that the Radio interests have awakened to the fact that a broadcasting station on top of their roof will pay for itself within 48 hours.
    And we are only at the very beginning of things. Thus, for instance, the American Telephone and Telegraph Company is now erecting in New York City, the most powerful broadcasting radio telephone station in the country. And for what purpose do you think they are doing it? To rent out the station!
    In other words, within a month from the date this is written, the advertising manager of a big New York department store may reach for his desk telephone, and talk over the new broadcasting station to several hundred thousand people, giving them the latest prices and sales talk from gold fish to pianos. He need not leave his desk, as his telephone through "Central" will be connected to the broadcasting station. Thence his voice will be connected with the Radio transmitter to be hurled out into space. The American Telephone and Telegraph Company will hire out their station to anyone who wishes to rent it for any length of time, day or night. This may seem nothing but a stunt to us, but it is the coming thing. It merely goes to show what a tremendous grip the Radio telephone has upon the popular imagination to-day.--EDITOR.
SUPPOSE the American Telephone and Telegraph Co. and its local subsidiary companies had tried to build up a business as the radio interests are trying to build up theirs. Suppose that, instead of issuing directories telling whom you can talk to with a telephone, they should offer you an installation backed up by only two arguments: First, that you can talk; second, that you can hear. Would you fall for such a proposition?
    Maybe you would. Phonographs were sold in the early days even though there was little in the way of records to play on them. People are still buying toy motion picture machines with only 20' of film. They are still born at the rate of one every minute, or more. But the manufacturer or dealer who wants to sell radio, keep it sold and build up a business, must recognize the fact that at the present stage of the industry the middle eighty per cent of the population is his field, not the submerged tenth who fall for a thing just because it is new, nor the intellectual ten per cent who are capable of learning radio. The "radio amateur" represents only the big game, like the elephant or moose that can be stalked and brought into camp occasionally. Some people make money hunting elephants. Also some can sell Rolls-Royces, but Henry Ford is the only man today who is rated higher than John D. Rockefeller, and both of them built their successes on the common people. The common people are ripe for radio if they are told what they can hear. I have answered during the past year several hundreds of letters from men and boys who wanted to use radio. I am beginning to get letters now from women, and women spend more than eighty per cent of the household funds. Practically every letter shows that the common people are hopelessly confused by the advertising, the catalogs, and even by the radio magazines. What they want to know is: "What can I hear with a radio outfit and how can I hear it?"
    Careful inquiry failed to reveal any list of the things that common folks--those who want to use radio without studying the theory, learning the code or building, apparatus--could hear. We have our call books, but they are all Greek to the novice. Even these of us who have used them for years cannot get out of them what the common people want to know, because it is not there. These books do not tell about the concerts, the lectures, the bedtime stories, the church services that are in the air. Those are the things that the army of new radio customers wants to know about.
    Thinking that the collection of a list of broadcasts of interest to the public would be of service in the promotion of radio as a household utility, I wrote to all the manufacturers and dealers whose names and addresses I could secure. To my utter astonishment the replies showed that not one out of three knew himself what could be heard with the apparatus he made and sold. Even the fact that the list was to have a circulation of at least half a million, among persons who would be influenced by thousands to buy radio receivers, failed to stimulate many of them to the point of digging up such local information as they could secure in five minutes' conversation with any enthusiastic amateur.
    Many of them gave me the information that they were very busy. I was interested in that, but it was no news to me. From radio departments in department stores to the high class shops specializing in radio, I had heard of the fact that the manufacturers had fallen down--that deliveries, just at the beginning of a radio era that should make millionaires, were 30 days and more behind. No manufacturer, so far as I could learn, had had confidence enough in himself and his business to use the dull months last summer to really get ready for the holiday trade.
    But a few came across with lists of voice broadcasts. Altogether, the list is impressive, though I doubt if it contains twenty-five per cent of the reliable broadcasts that people would buy receivers to hear.
    In Washington I have been getting White and Boyer's concerts once or twice a week Once a week I heard a lecture from the United States Public Health Service, with music before and after. From the Church of the Covenant I have heard not only the morning and evening services but also afternoon addresses by eminent men and women. To get all these things, I have used a mineral detector set that cost less than $30 to buy and install. I could have managed it successfully without any technical knowledge. Other folks in the house learned to use it in a few minutes. But the people of Washington do not know that such a boon is within their reach. They have read about it, but they do not know it. I have talked with scores of them and they have marvelled at the simple facts that I have given them.
    The man who sold me the set would have sold me a regenerative receiver if he had had his way. He would have had me all tangled up in complicated connections, doubtful about the expediency of bringing into the house a storage battery full of sulphuric acid solution that eats whatever it touches if it is spilled, prudently considering problems of upkeep that do not arise in using the simple set I bought.
    These Washington broadcasts could be maintained just as well in the summer time, when atmospheric conditions cause the DXer to pack up his troubles, leave them in the closet and go off for a vacation. More people stay at home than can afford to go away. If they can bring in a concert from five miles away, they should worry because the range of the broadcast is cut down from 300 miles to 30, by the summer static.
    My list of broadcasts probably contains errors. Much of the information is from listeners, and not all of it has been checked up by the broadcasting stations. But such as it is, I got it up with my own money and with the kind co-operation of a few manufacturers and dealers, and I offer it to radio men for what it is worth. Somebody, I hope, will be inspired to maintain a complete list and keep it accurate and up-to-date. Such a list could be printed in a booklet, with a manufacturer's or dealer's advertising, and given away to prospects and customers, or sold for enough to cover the cost of printing.

MOST  IMPORTANT  BROADCAST  OF  ALL  FOR  YOU

    The Amateur Broadcast transmitted from the United States Navy Station NAH, New York City, daily about 9.30 P. M., on 1832 meters is undoubtedly the most important broadcast for the American citizen to receive.
    The message usually is short, about 25 words. It is sent at slow speed, 10 words per minute, and with great distinctness.
    The message is always of interest and often of value, but the importance of the broadcast does not depend upon that alone. It is the means by which the citizen may keep in direct touch with our Government and make sure of receiving instant advice concerning an impending disaster, such for instance as the approach of a hostile air fleet, or the menace of an epidemic against which immediate precautions might prevail.
    Every American community is neglecting one of its greatest opportunities if it fails to receive this broadcast daily, and thus keep the line of communication open. One boy, or young man, or girl in any community, with an efficient radio receiver, could maintain this contact with Washington. In time of danger a continuous watch could be maintained--an easy matter if the system is once established locally. The Boy Scouts of America are especially encouraged to serve as operators and messengers in this system.
    In times of danger, speed is necessary. Wire service is fast, but radio is instantaneous. One Government official in Washington could give a word of warning to every American community at the same moment if every community were listening.
    Sometimes, to provide a means of secrecy, these messages are transmitted in Navy Amateur Code. Key to the codes used will be sent free on request by the Seascout Radio Commodore, 200 Fifth Avenue, New York City.

These stations are sending the time signals 12 hours apart, yet they are received in Boston simultaneously. Nauen is sending signals at midnight. . . . The time signals from Honolulu are being sent out at 12 o'clock noon of the previous day. Because of the difference in time both come in at Boston at 7 :00 o'clock P. M.

    The Westinghouse Company's radio telephone broadcasting station in Newark is one of the most powerful in the country and, like this company's stations in Springfield, Mass., Pittsburgh, and Chicago, provides varied entertainment for all who listen in during the day and evening. With proper receiving apparatus Westinghouse Broadcasts may be heard over practically the entire Eastern United States and the addition of multistage amplifiers and loud speakers will make the music, sermons and other things audible throughout the largest auditorium.
New York City. A list of all that can be heard with a radio receiver anywhere within three hundred miles of Greater New York would fill a book. At any hour of the day or night, with any type of apparatus, adjusted to receive waves of any length, the listener will hear something of interest. Scores of ships may be heard exchanging messages with shore stations or with each other in the International Morse Code. Many of them have radio telephones also and conversations may be heard in many different languages. Government stations send out weather forecasts, hydrographic information and time signals. Amateurs signal in Morse code, converse over radio telephones or amuse the world by playing jazz. At times there is so much going on that it is difficult to tune out all but the station that the hearer wishes to receive, though the selectivity of modern tuning apparatus is marvelous. By merely listening in and writing down the adjustment of the receiving apparatus at the time when it brings in each station, anyone may quickly develop a list of broadcasts and then add to it each day as new and interesting stations are discovered.

It will distribute crop and weather reports and cooperate with the State Department of Forestry by reporting forest fires. Intertroop communication will be maintained between Scouts in all parts of the State. Concerts, lectures and addresses given at the Municipal Auditorium will be broadcasted. The station is reported to be in charge of 16 Scouts under the leadership of a Scoutmaster who was formerly a radio inspector.

    Some of the most important Government stations are located in the vicinity of Washington. The Arlington station of the Navy, call letters NAA, transmits time signals and news on 2,650 meters daily at noon and 10 P. M. This station and the still more powerful one at Annapolis, which transmits similar information on the same schedule, can be heard throughout the United States and in fact throughout a large part of the world. The station at the Bureau of Standards conducts tests in which it has the coöperation of many amateur stations. Then there are Army stations and stations connected with the Army and Navy flying fields. Radio telephones may be heard frequently. Loomis Radio School is planning to broadcast, daily, music played in a local theatre.

Anywhere in the United States. With an up-to-date long-wave receiver, it is possible to get the news broadcasted by high powered stations in the British Isles, Germany, France, Italy, Russia, Mexico, West Indies, South America, Hawaii. With the increase in power of transmitting stations world-wide reception has become possible. Radio Central the new commercial station of the Radio Corporation of America, located at Rocky Point, Long Island, New York, has been heard in New Zealand, 10,000 miles away.

Callsigns and Licence Classifications: Most of the stations listed above which have callsigns starting with K or W (WRR, WGI, KYW, KZY, WQB, WJZ, 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 8UX in Akron, Ohio, 4BQ in Rome, Georgia, 3AWI in Philadelphia, Pennsylvania, 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 8XB in Cincinnati, Ohio, 2XQ in Schenectady, New York, 1XAD in Pawtucket, Rhode Island, 9XM in Madison, Wisconsin, and 9XAB in Kansas City, Missouri. Technical and Training School licences were most commonly issued to colleges and universities, and their callsigns had a Y immediately after the district number. Technical and Training School stations in this list include 8YO, Columbus, Ohio (Ohio State University), 9YA Iowa City, Iowa (University of Iowa) 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 special Amateur stations include 9ZAF in Denver, Colorado, 3ZO in Parkesburg, Pennsylvania, and 5ZC in Dallas, Texas.

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, for example NAA in Arlington, Virginia. The U.S. Army stations were supposed to use calls starting with WUA to WVZ and WXA to WZZ. However, other Army stations at this time seem to have used whatever calls they wanted, such as Fairfield, Ohio's WL2 and Dayton, Ohio's WA1. Finally, there is one foreign call included--XDA, in Mexico City, Mexico.

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.
