Breaking News: First ZS EME Record on 10 GHz (3 cm) 

On 22 October 2017 at 15:46 UTC, Alex Artieda, ZS6EME, recorded the first-ever Digital EME QSO with HB9Q on 10 GHz. This is the first Microwave EME QSO on such a high band from South Africa and operating the new digital mode QRA64D, while using only 50 Watts at the feed of his 1,5 metre dish. Later on 23 October Alex completed 10 more EME QSOs on 10 GHz.

Last but not least on 24 October, he was able to make the first-ever Digital EME QSO in 5,7 GHz (6 cm) in the RSA with PA3DZL at 11.56 UTC, and on the same day he completed 7 more QSOs on 5,7 GHz.

Hearty congratulations to Alex for his fantastic achievements and putting South Africa back on the world Microwave map.
