NCDXF/IARU Beacon Transmission Schedule

horizontal rule

Important New Automated Beacon Monitoring Program

The beacons transmit every three minutes, day and night. This table gives the minute and second of the start of the first transmission within the hour for each beacon on each frequency. A transmission consists of the callsign of the beacon sent at 22 words per minute followed by four one-second dashes. The callsign and the first dash are sent at 100 watts. The remaining dashes are sent at 10 watts, 1 watt and 0.1 watts.

The actual starting time of each transmission is approximately twenty milliseconds after the nominal time due to the keying delay of the transmitter. Equipment used at each beacon site includes a Kenwood TS-50S transmitter, a Cushcraft R-5 vertical antenna, a Trimble Navigation Acutime GPS receiver and a controller built by the NCDXF.

Fabry, QST, October 1994 pp. 31-33 and November 1994 pp. 49-51, The NCDXF/IARU International Beacon Project by John G. Troster and Robert S.
