DL3RTL/b is a HF radio propagation beacon and amateur standard frequency radio station based in Berlin, Germany.
The frequency has been officially coordinated by the IARU.
The purpose of our station is the investigation of the propagation of radio signals. DL3RTL/b is broadcasting on HF (shortwave) and operating in continuous wave (CW, A1A) and alternatively Frequency Shift Keying (FSK, 800Hz shift) to transmit the identification with call sign, location and additional information.
DL3RTL/b also provides amateur standard frequency with an accuracy of +/- 0,002Hz in normal operation. The exact frequency is controlled by direct digital synthesis and locked by GPS time information.
DL3RTL/b is an excellent indicator of ionospheric propagation to the Berlin area, eastern Germany as well as the western Poland areas.
The manned station is operated and controlled by Daniel Möller, DL3RTL.
All Systems are working fine.
