2014/Octorber/31 Nighttime Operation Report

Operation report from JQ1YGV Nihon university ground station.

国内外問わず,続々と受信報告を頂いております.
皆様のご協力に大変感謝しております.
Thank you so much for all who helped us to receive.

[現在のSPROUTの状態]/[Current status of SPROUT]

現在SPROUTはCW(通常モード:G3/437.525MHz)運用を行っています.

Current status of SPROUT is CW(nomal mode:G3/437.525MHz).

[次回の運用内容]/[Next Operation]

昼間の1st,2ndパスは,CW(Normal Mode:G3/437.525MHz)にてバス電圧値を確認した後,FMダウンリンク(FM:GMSK(9600bps/437.525MHz)))を行います.

11月2日の運用では,まずCW(Normal Mode:G3/437.525MHz)にてバス電圧値を確認した後,SSTVを行います.受信周波数はCW運用時437.525[MHz],SSTV運用時437.600[MHz]です.

The Daytime 1st and 2nd Operation is FM downlink(FM:GMSK(9600bps/437.525MHz))), after checking the voltage in CW(Normal Mode:G3/437.525MHz).

11/2 operation is SSTV(437.600MHz), after checking the voltage in CW(Normal Mode:G3/437.525MHz) .
