Moon Opera

The AMSAT News Service and the South African Radio League both report on a new moonbounce achievement by two amateurs in Spain – the first reception of signals off the moon using the "Opera" weak-signal mode. EA5DOM was listening for Opera signals transmitted by EA3HMJ. 

Initial tests on 1296 MHz resulted in a visible trace that was too weak to decode. That was followed by a successful decode on 70 MHz, the 4-meter band, which is available to hams in many parts of Europe and Africa. EA5DOM promised more tests but noted that "one decode was worth the effort."
