Betreff: World's first 76GHz EME QSO
The world's first 76 GHz EME QSO took place on April 22, 2026, between RW3BP (KO85) and DL7YC (JO62).
Sergei utilized a 2.4m offset dish paired with an 8.2-watt SSPA and a 2.4 dB NF LNA.
Manfred (DL7YC) employed a 2.4m prime-focus dish with a 5-watt SSPA and a 2.5 dB NF LNA.
The transmission mode used was Q65-60E, during which "single decode" reports of -14/-15 and -17, respectively, were exchanged.
A unique feature of this operation was that, due to the high losses at 76,003.210 MHz, no antenna relays were utilized; instead, the receivers and transmitters each employed separate feedhorns that were "slid" into the focal point with an accuracy of 0.05 mm.
Best regards
Sergei, RW3BP
Manfred, DL7YC
