4M – Chang Zheng CZ-3C-G2 launch vehicle

The 4M amateur radio payload with a WSJT JT65B 145.980 MHz beacon was launched on Thursday, October 23 at 1759 UT.

The Chang’e-5-T1 mission 4M payload launched on the Chang Zheng CZ-3C/G2 rocket from the LC2 launch complex at the Xichang Satellite Launch Center, Sichuan. The first telemetry from the JT65B beacon was received at 1918 UT by Roland Zurmely PY4ZBZ in Brazil.

A number of Australian radio amateurs have reported receiving the signals from 4M. Among them was Rob Whitmore VK3MQ at Mount Dandenong, Victoria (QF22qe) who reports that at best, the strength was -13 on the JT65B scale and could also be totally down into the noise with no decodes.

Rob VK3MQ says “I am using the “Before” TLE as published on the Luxspace website with Gpredict to stear my 6 element yagi and TS2000. With Doppler the frequency is 145.9787 MHz at the time of writing. So far the decodes have included callsign, telemetry and a story of Manfred Fuchs threading through alternate decodes.”

Sam Jewell G4DDK @DXING Tweeted “Had around 40 minutes of near 100% copy from the moon probe 4M transmitter from around 1725z [Oct 24]. 9 element Yagi and K3/2m on 2m /JT65B”

The spacecraft will head into a Lunar Transfer Orbit (LTO), before performing a flyby around the Moon. Radio amateurs are encouraged to receive and report the signals. http://moon.luxspace.lu/receiving-4m/
