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(normal mode:G3/437.525MHz).

[次回の運用内容]/[Next Operation]
夜間の4th,5th,6thパスは,SSTV(437.600MHz/AFSK)を行います.
The nighttime 4th, 5th and 6th operation is going to operate SSTV(437.600MHz/AFSK).

[運用のお知らせ]/[Operation info.]
次回のSSTV運用は1/11を予定しています.
We will operate SSTV downlink(437.600MHz) on 1/11.

[運用結果]/[Operational results]
2015/1/11 昼間の運用を3パス行いました.
2015/1/11 Daytime operation: We have conducted 3 operations.

1st:CW:S0[dB] FM:–[dB] Digi:–[dB] Bus Voltage:-.—[V]
2nd:CW:S3[dB] FM:S5[dB] Digi:–[dB] Bus Voltage:4.877[V]
3rd:CW:S3[dB] FM:S3[dB] Digi:–[dB] Bus Voltage:4.828[V]

1st:ノイズが多く,デコードには至りませんでした.
2nd:CW運用にて,バス電圧4.877[V]を確認後,アップリンクを行いSSTV(437.600MHz)を行いました.
3rd:CW運用にて,バス電圧4.828[V]を確認後,アップリンクを行いSSTV(437.600MHz)を行いました.

1st:We couldn’t confirm bus voltage because of the noise.
2nd:We confirmed bus voltage 4.877[V] by CW operation. After that we have operated SSTV(437.600MHz).
3rd:We confirmed bus voltage 4.828[V] by CW operation. After that we have operated SSTV(437.600MHz).
