via the ARRL: Historic Amateur Radio Contact Reported via Moon-Orbiting Satellite

A contact between a radio amateur in Germany and China took place on July 1 via the moon-orbiting LO-94 satellite, DSLWP-B, launched in May 2018. The two-way exchange between Reinhard Kuehn, DK5LA, in Soerup, Germany, and Harbin Institute of Technology club station BY2HIT (operated by Wei Mingchuan, BG2BHC), in Harbin, China, occurred between 0551 and 0728 UTC, according to reports. The GMSK-to-JT4G repeater onboard DSLWP-B was used to make the contact, the first ever made via a lunar-orbiting repeater.

“Using the GMSK-to-JT4G repeater is not easy, in terms of the signal power needed for the uplink,” commented radio amateur and engineer Daniel Estévez, EA4GPZ, whose blog includes images of the lunar surface downloaded via DSLWP-B. “There were plans to make a QSO between BY2HIT and Reinhard since many months ago, but previous attempts didn’t work out. My congratulations to the people at both sides of the QSO, who have achieved it a month before DSLWP-B crashes against the lunar surface.”
