OZ7IGY is a Danish amateur radio beacon, and the world's oldest[1] VHF and UHF amateur radio beacon and active since the International Geophysical Year in 1957.[2] It is located near Jystrup, in Maidenhead locator JO55WM54, and transmits on the frequencies detailed in Table 1.

Since 30 October 2012, when the Next Generation Beacons platform came into use, the 2 m and 6 m beacons have been frequency and time locked to GPS.[3]

From 30 March 2013 all the beacons using the Next Generation Beacons platform transmit PI4 (a specialized digital modulation system), CW and unmodulated carrier in a one-minute cycle. The frequency precision of the Next Generation Beacons is typically better than 5 mHz. Over time all the OZ7IGY beacons will use the Next Generation Beacons platform.[4]
