WDBG's transmitting wavelength of 278 meters corresponds to 1080 kilohertz.

_____

    All arrangements have been completed for the broadcasting of the Armistice Day address to be delivered here at four o'clock" in the afternoon of November llth, in conjunction with the peace time patriotic demonstration under the auspices of the local American Legion Post.
    Arrangements were made with the Gettysburg College Radio Broadcasting station for the use of the apparatus at the school, which will be removed to the speakers stand on Center Square for the afternoon exercises of the Legion's Armistice Day celebration.
    It was at first announced that the broadcasting would be in charge of the Third Corps recruiting station, whose apparatus was made available to the Legion some time ago. This was changed, however, when the officials in charge ef the College's broadcasting station volunteered the use of their equipment together with radio man to assist in operating and broadcasting.
    This is second time that a public address has ever been broadcast out of Gettysburg and the Legion is fortunate in securing the radio equipment together with a well trained radio expert to assist in broadcasting over the country the address which will be delivered here.
    The general committee of the Armistice Day celebration has not definitely settled upon the speaker for the day. Senator Matthew M. Neely, of West Virginia, was selected, but due to a change in plans this information was later revoked.
    Senator Pepper of Pennsylvania and Senator Pat Harrison, of Mississippi are now being considered and final announcement will be made within the next few days.

Call letters WDBG have been assigned the local station for broadcasting Senator Gore's address.

MANY  FANS  HEAR  RADIO  PROGRAM
________

Reports  Received  From  Far  West  That  Armistice  Day  Radio  Program  Is  Well  Received.
________

    The radiocasting of the events of Armistice Day proved a great success and gained favor with many listeners in widely separated parts of the country if reports which have been coming in can be used as means of indication.
    The Gettysburg College radiocasting station was used to broadcast the events with call letters WDBG and wavelength of 278 meters. The installation and operation of the transmitting apparatus at the college and of the pickup devices and speech amplifiers at the speakers stand and Naturay Springs Park were largely done by H. W. Baker, of Baker's Battery Service, and E. G. Ports, instructor of physics, Gettysburg College. A large part of the successful transmission by radio of the events of Armistice Day was due to the Cumberland Valley Telephone Company. This company gave two of its best lines over exclusively for use in connecting the transmitting station with the speakers stand and the Natural Springs Park. Special work was done on both lines to fit them for the purpose and the employes of the company did everything in their power to make the thing a success by giving without charge this service.
    Reports came in from all sections of the country as far west as Arkansas and Michigan telling how the program and transmission was enjoyed, a great number of the listeners expressing their wishes that the programs be continued.
    Thus the step taken by the Legion in having Armistice Day program radiocast accomplished a step in placing not only the Legion before many people but also in placing Gettysburg befure many who may have known of the town only as one which was concerned with the Civil War. Perhaps the initiative taken by the Legion may finally lead to the establishment of a regular radiocasting service from Gettysburg--telling the outside world about Gettysburg and giving it a publicity gained by no other means.
