NCDXF Beacons Reception at EI4HQ (IO51uu)

UPGRADE WORK (Updated 2017-06-24): A major upgrade to improve NCDXF beacon monitoring and other services provided by EI4HQ (Cork Harbour HD webcam, AIS data feed, ADS-B data feed and Cork Harbour Weather data) is progressing. You can read about it here. The NCDXF beacon monitoring reconditioning work is now complete other than some software changes that will be implemented in the Autumn.

This page contains reception reports for the IARU/NCDXF International Beacon Project beacon network on the 14Mhz (20m), 18MHz (17m), 21MHz (15m), 24MHz (12m) and 28MHz (10m) amateur radio bands. The receiver is a Kenwood TS-450SAT and the antenna is a dedicated quarter wave vertical tuned for 21.150MHz (i.e. the mid-band of the NCDXF beacons), installed 15 metres above ground (93m above sea level) with a 4 radial ground system and fed via a 1:1 balun by RG213 coax. The antenna location has full uninterrupted visibility around 360° i.e. no obstructions in the near field. An interswitch is fitted to de-sense the receiver when the main station is transmitting.

Location: Cobh, Co. Cork, Ireland. IO51uu. Latitude: 51 51.85'N, Longitude: 008 17.29'W.

The "on-air" status of each beacon can be seen here and other Beacon Monitor web pages are linked from the International Beacon Project Monitors site.
