EME 76 GHz - Pierwsza łączność na świecie

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.
