2014/September/7 Daytime 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]

夜間の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.
夜間の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60分間行う予定です.
夜間の3rd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(9月6日,7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 nighttime 1st Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV downlink(437.600MHz) for 60 minutes.
The nighttime 2nd Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV downlink(437.600MHz) for 60 minutes.
The nighttime 3rd Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV downlink(437.600MHz) for 120 minutes.

This weekend (9/6,7) Operation is SSTV (437.600MHz), after checking the voltage in CW(Normal Mode:G3/437.525MHz) .

[運用結果]/[Operational results]
2014/9/7 昼間の運用を3パス行いました.
2014/9/7 Daytime operation: We conducted 3 perations.

1st:CW:S1[dB] FM:S4[dB] Digi:-[dB] Battery Voltage:4.730[V]
2nd:CW:S0[dB] FM:-[dB] Digi:-[dB] Battery Voltage:-.–[V]
3rd:CW:S0[dB] FM:-[dB] Digi:-[dB] Battery Voltage:-.–[V]

1st:CW運用を行いバッテリ電圧値4.730[V]を確認しました.その後SSTVダウンリンクを60分行いました.
2nd:CW運用を行いましたが,ノイズが多くバッテリ電圧を確認できませんでした.
3rd:CW運用を行いましたが,ノイズが多くバッテリ電圧を確認できませんでした.

1st:We have confirmed battery voltage (4.730[V]),and we operated “SSTV downlink” for 60 minutes.
2nd:We couldn’t confirm battery voltage for noise.
3rd:We couldn’t confirm battery voltage for noise.

次回のパス情報は以下のようになります.
