Broadcasting in Europe

~-- , A Frequency Check ‘ ST iemaieniemmennal IN view of the increasing congestion of the European ether and the consequent necessity that transmitting stations should not depart from their al-> lotted wave-lengths, it is essential. $ means should exist for their exact calibration. For some time past the German high-power transmitter at Koenigswusterhausen has broadcast at regular periods calibrated waves for the benefit of Europe in general, and of its own tountry in particular, At the beginning of each transmission a short tuning signal is sent out, and is followed by the call-sign in Morse. In the cd by the call-sign in Morse. In the event of any unforeseen interrupcion taking place, in order that the time schedule’ should not be. completely upset, the "missing". signals are specially broadcast.at the end of the transmission and an announcement made to that effect; As these signals are accurately measured, the broadcasts are regularly used by both German telegraphy and telephony transmitters to check their wave-lengths, and should also prove of use to amateurs for the calibration of medium and long-wave wireless receivers.
