OZ7IGY dates back to the International Geophysical Year in 1957. From its start on 144 MHz it has been on air on more and more bands. Today OZ7IGY transmits on 28 MHz, 40 MHz, 50 MHz, 70 MHz, 144 MHz, 432 MHz, 1,3 GHz, 2,3 GHz, 3,4 GHz, 5,7 GHz, 10 GHz and 24 GHz. In the past most of the equipment was modified land mobile equipment. For the microwave bands most of the technology was dedicated radio amateur beacon designs and power amplifiers surplus. Today all but the 40 MHz and 10 GHz beacons use the Next Generation Beacons platform.
|Frequency [MHz]||USB dial*
||ERP [W]||ASL [m]||99% accuracy [mHz]||Year QRV|
|10 368,930||10.368.929.200||140||96||Not locked!||1999|
|Notes:||Active beacon||Out of service||Upcoming maintenance, see event log||*: On most radios|
All the beacons, except the ones on 40 MHz and 10 GHz, transmit in a 60 s mixed mode sequence (PI4 + CW + carrier) and are GPS locked. This ensures a frequency accuracy that 99% of the time is better than the values listed above.
On 30 October 2012 the first two Next Generation Beacons were put on air. The Next Generation Beacons platform is open to others and the software can easily be adapted to other modulations and sequences. Emanuele, IW9GDC and beacon manager of IW9GDC/B that also uses the Next Generation Beacons platform says: “… I can really say that this hardware is actually the best ever made … 4 km straight line and cannot detect any issue with the signal.”
