For those of you interested in the Next Generation Beacons project a new software package for the DDS unit has just been released (1.2.0). New features are WSPR-15 among others: http://www.rudius.net/oz2m/ngnb
The Next Generation Beacons platform is open to others and the software can easily be adapted to other modulations and sequences. Furthermore, is the new platform frequency and time locked to GPS. Thus the frequency accuracy is better than 5 mHz.
OZ7IGY is the world's oldest beacon having started in the International Geophysical Year in 1957. From its start on 144 MHz it has ever since been on air continuously and on ever 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.
