A number of the WD2XSH experimental stations will be on the air on Thursday, November 3 to mark the 105th anniversary of the Berlin International Radiotelegraphic Convention. According to ARRL WD2XSH Coordinator Fritz Raab, W1FR, stations operating in the band from 495-510 kHz will call CQ on 500 kHz and then QSY to complete the QSO. Stations operating in the band from 461-478 kHz will call CQ on 474.5 kHz and then QSY. Other stations may operate beacons with special messages in the bands from 508-510 kHz and 476-478 kHz.
