375-Mile Wireless Talk.

New York Times 100 years ago today, May 29, 1913:
Telephonic Conversation Between Berlin and Vienna Is Easy.
Special Cable to The New York Times.
    BERLIN, May 28.— Successful wireless telephonic communication has just been effected between Berlin and Vienna, a distance of about 375 miles. The trials have been so promising that a foreign station 750 miles distant from Berlin is now being sought.
    Communication was established between the great German central wireless station tower at Nauen, west of Potsdam, and the receiving station on the roof of the Technological and Industrial Museum in Vienna. The sounds transmitted consisted of both speech and music, which could be heard with great distinctness. High frequency apparatus was employed in conjunction with microphones. The waves were caught up in Vienna, and the messages they bore were conveyed to the ear by means of a regular telephone receiving apparatus.
    Nauen also talked by wireless with a number of German military stations at remote frontier points.
