WDBG's transmitting wavelength of 273 meters corresponds to 1100 kilohertz.
Gettysburg (Pennsylvania) Times, May 27, 1924, pages 1, 3:


Invitation  to  Congressmen  to  Come  Here  Friday  Has  Been  Issued.


Wants  His  Colleagues  to  Attend  Services  Here;  Radio  Broadcasting  Plans  Perfected  and  Apparatus  Ready.

    With the close approach of the time for the Memorial Day exercises which be given at the National Cemetery here on Friday afternoon announcement is made by the members of the Grand Army of the Republic post here, who have charge of arrangements for the program, that all is in readiness for the celebration
    Wires, which will transmit the exercises from the battlefield to the radio broadcasting station at Gettysburg College, have been erected and work of testing them out in every detail is being carried out by Earl G. Ports, instructor in the department of physics at the College, and by H. W. Baker, of Baker's Battery Service, Baltimore street. Mr. Baker and Mr. Ports will be in charge of the transmitting apparatus on the day of the 30th, when thousands of radio "listeners-in" will be given an opportunity to participate in the Memorial services, although unable to be present in person. The station will use 100 watts for power on Friday.
    Invitation to be present at the services here on Friday was extended by Congressman Samuel F. Glatfelter to his colleagues in Congress. Mr. Glatfelter, representing the Twenty-second district, in which Gettysburg is situated, made the following statement on the floor of the House:
    "Since I have the honor of representing the District in which historic Gettysburg is situated, it gives me pleasure to announce to my colleagues in Congress and the country in general that the Memorial Day exercises will take place at the National Cemetery in Gettysburg on Friday, the 30th of May, the exercises beginning immediately after the noon hour.
    "The annual address will be delivered near the spot where Lincoln stood, by our colleague, whom we delight to honor, Hon. William D. Upshaw, of Georgia, and this feature carries with it peculiar interest, in face of the fact that the invitation to deliver this address has been extended by the Grand Army of the Republic to the son of a Confederate soldier, whose loyalty to all things distinctly American is nationally known.
    "I am glad also to announce that this address will be broadcast for the benefit of many thousands at a distance who will not be able to join in person the patriotic throngs who always assemble at Gettysburg on our National Memorial Day.
    "The Gettysburg Times makes the following announcement for the sake of those who wish to 'listen in':
    " 'The College transmitting station, which is under the direction of Earl G. Ports, instructor in the department of physics, has been granted a special license good only for the day of May 30, when broadcasting may be done on a wave length of 273 meters. While the station has for some time been operating on a wave length of 200 meters, the longer wave length was desired in order that more radio fans throughout the country would be able to tune in on the exercises here. Few receivers, it is stated, will tune as low as 200 meters. Temporary call letters of WDBG have been assigned to the College for the Memorial Day occasion, the call letters of the station when it is operating on a wave length of 200 meters being 3BHY.'
    "It is 83 miles over a beautiful road from Washington to Gettysburg, and I hope that many of my colleagues in Congress, as well as other Washington friends, will honor the most historic spot in my district, if not in America, with their presence on this great occasion of nation-wide interest."
    In view of severe criticism which has been made in the past by Gettysburg radio fans, concerning the radio work done by the College transmitting station, 3BHY, Mr. Ports has issued a statement in defense of the work which has been carried on there for the past year.
    Mr. Ports says that the station has not been broadcasting, but has only been trying to develop a transmitter which would be suitable for broadcasting purposes. He was assisted in this work by Mr. Baker, Baltimore street, and also by Professor A. D. Morganthall, of the local High School; the tests have not been without results, it is declared, for the transmitter is now nearly perfect, according to reports from listeners in many parts of the country.
    In the near future, it is hoped that the College station, 3BHY, can be used to broadcast entertainment in the form of music, lectures, speeches, plays, games and addresses, at the same time giving publicity to both the town and the College, thus stimulating tourist trade and putting Gettysburg before the radio listening public, a vast audience. The cooperation of the Gettysburg Chamber of Commerce is being sought in this work, Mr. Ports said.
    "In my work at 3BHY, on testing, I have been greatly assisted by suggestions from Dr. L. A. Parsons, by able assistance in construction, installation and operation of station by Mr. Baker and Professor Morganthall, says Mr. Ports.
    "In addition to this I have also been aided by the consideration tolerance of local listeners who through faulty receivers or aerials of too great length have not been able to tune out my transmission although it was done on 200 meters.
    "I might add that broadcasting at the College should not interfere with local listeners who wish to tune other stations if proper receivers are used. As proof of this, I might say that Mr. Baker at various times, on commercial receivers, was able to tune out my transmission and tune in distant stations, from his establishment on Baltimore street."

Although  Large,  Crowd  Was  One  Of  The  Most  Orderly  in  Years.


More  School  Children  Than  Ever  Before  in  Annual  Parade;  Local  Radio  Fans  Hear  Address.

    Between 20,000 and 25,000 persons in Gettysburg helped make Memorial Day 1924 one of the most memorable in the town's history.
    Broadcasting of the exercises at the rostrum was successfully carried out, the first time in history that this feat has been attempted. The receiving set was carefully hidden on the rostrum, the only parts showing being two mouthpieces, before the speaker's table. Local radio fans who tuned in with the Gettysburg College broadcasting station, which sent out the exercises, said they had no trouble picking up the station or of hearing most of the address and the other numbers on the program at the rostrum. No reports had been received to noon today on how far away the exercises were heard.
