2014/August/24 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パスは,CW(Normal Mode:G3/437.525MHz)にてバス電圧値の確認を確認した後,SSTV(437.600MHz)を60分間行う予定です.
昼間の2ndパスは,CW(Normal Mode:G3/437.525MHz)にてバス電圧値の確認を確認した後,SSTV(437.600MHz)を120分間行う予定です.

今週末(8月30日,31日)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 Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV downlink(437.600MHz) for 60 minutes.
The daytime 2nd Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV downlink(437.600MHz) for 60 minutes.

This weekend (August/30,31) Operation is SSTV (437.600MHz), after checking the voltage in CW(Normal Mode:G3/437.525MHz) .

[運用結果]/[Operational results]
2014/8/24 夜間の運用を2パス行いました.
2014/8/24 Nighttime operation: We conducted 2 perations.

3rd:CW:S1 FM:S[dB] Digi:-[dB] Battery Voltage:3.833[V]
4th:CW:S1 FM:S[dB] Digi:-[dB] Battery Voltage:3.83[V]

3rd:CW運用を行い,バッテリ電圧(3.83V)を確認しました.
4th:CW運用を行い,バッテリ電圧(3.83V)を確認しました.その後アップリンクを行い,SSTV運用を60分間行いました.

3rd:We have confirmed battery voltage(3.83V).
4th:We have confirmed battery voltage(3.83V), and we operated “SSTV downlink” for 60 minutes.
