2014/August/22 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60分間行う予定です.

今週末(8月23日,24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.
The daytime 3rd Operation check the voltage by CW(Normal Mode:G3/437.525MHz), SSTV downlink(437.600MHz) for 120 minutes.

This weekend (August/16,17) Operation is SSTV (437.600MHz), after checking the voltage in CW(Normal Mode:G3/437.525MHz) .

[運用結果]/[Operational results]
2014/8/22 夜間の運用を3パス行いました.
2014/8/22 Nighttime operation: We conducted 3 perations.

3rd:CW:S4 FM:S7[dB] Digi:-[dB] Battery Voltage:3.798[V]
4th:CW:S0 FM:S7[dB] Digi:-[dB] Battery Voltage:-.—[V]
5th:CW:S0 FM:-[dB] Digi:-[dB] Battery Voltage:-.—[V]

3rd:CW運用を行い,バッテリ電圧(3.798V)を確認しました.
4th:CW運用を行い, TestFMダウンリンクを行いました.
5th:CW運用を行いましたが,バッテリ電圧を取得できませんでした.

3rd:We have confirmed battery voltage(3.798V). 
4th:We operated “TestFM downlink” for 60 minutes.
5th:We We couldn’t confirm bus voltage, for noise.
