Shin-en2 Deep Space Probe Reception Reports

(2014-12-15) PE1ITR
This webpage is about my Shin-en2 Spacecraft receive experiments on 437MHz. Shin-en2 and ARTSAT2:DESPATCH spacecrafts are launched on 2014-12-03 together with the Hayabusa 2 and are cruising into deep space.

Until now I could receive the Shin-en2 spacecraft at a distance from 2.3 million kilometers from Earth.

The reception reports of ARTSAT2:DESPATCH are on this page.

Shin-en2 info:
Shin-en2: Telemetrie Downlink 437.385MHz. 0.8 Watts F1D Modulation

Signal Reception 2014-12-08 21:30UTC. 4 traces 441Hz spaced. 1st trace little above 437.379. Distance 2.308.000km The first trace of the signal starts little above 437.379MHz at the 21.29.54 mark. Then the next trace 441Hz higher. Total 4 Traces can be seen 441Hz spaced. This correlated to the Shin-en2 signal.
Signals are extremely weak now. I could pick this up by making use of the 6db groundgain advantage when the satellite rises (or sets) and goes through my antenna groundgain lobs.
