Our 70cms 432MHz beacon was built to replace the old GB3MLY beacon at Emley Moor.

Antenna: 3dBD Big Wheel at 10M ASL.


Keying Mode/duration: F1A – key down for 45 seconds, then CW ‘GB3FNY’ x 3

The 5.7GHz GB3KEU beacon was relocated to Finningley in 2015, it has had previous keepers in the past, and the beacon was built in memory of the late Tim Leighfield, G3KEU.
