Historic Amateur Radio Contact Made via Moon-Orbiting Satellite

摘要

A historic contact between radio amateurs in Germany and China via the moon-orbiting LO-94 satellite (DSLWP-B) took place this summer. The two-way exchange between Reinhard Kuehn, DK5LA, in Sorup, Germany, and Harbin Institute of Technology club station BY2HIT (operated by Wei Mingchuan, BG2BHC), in Harbin, China, occurred on July 1.The GMSK-to-JT4G repeater onboard DSLWP-B was used to make the contact, the first ever 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 Estevez, EA4GPZ, whose blog includes images of the lunar surface downloaded via DSLWP-B. For months, there were plans to make a contact between BY2HIT and DK5LA.The LO-94 satellite was to stop orbiting and be sent into the lunar surface before August.
