2014/September/15 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]

昼間のパスは,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.

9月16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 Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV (437.600MHz) .

9/16 Operation is SSTV (437.600MHz), after checking the voltage in CW(Normal Mode:G3/437.525MHz) .

[運用結果]/[Operational results]
2014/9/15 夜間の運用を3パス行いました.
2014/9/15 Nighttime operation: We conducted 3 0perations.

3rd:CW:S0[dB] FM:-[dB] Digi:-[dB] Battery Voltage:3.705[V]
4th:CW:S1[dB] FM:S7[dB] Digi:-[dB] Battery Voltage:3.701[V]
5th:CW:S0[dB] FM:-[dB] Digi:-[dB] Battery Voltage:3.7[V]

3rd:CW運用を行い,バッテリー電圧値3.705[V]を取得しました.
4th:CW運用を行い,バッテリー電圧値3.701[V]を取得しました.その後SSTVを60分間行いました.
5th:CW運用を行いましたが,ノイズが多く,電池電圧は確認できませんでした.

3rd:We have confirmed battery voltage (3.705[V]).
4th:We have confirmed battery voltage (3.7[V]), and we operated “SSTV downlink” for 60 minutes.
5th:We couldn’t confirm battery voltage for noise.
