2014/November/1 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]

11月2日の運用では,まずCW(Normal Mode:G3/437.525MHz)にてバス電圧値を確認した後,SSTV&デジトーカを行います.受信周波数はCW運用時437.525[MHz],SSTV&デジトーカ運用時437.600[MHz]です.

11/2 operation is SSTV&Digi-Talker(437.600MHz), after checking the voltage in CW(Normal Mode:G3/437.525MHz) .

[運用結果]/[Operational results]
2014/11/1 夜間の運用を3パス行いました.
2014/11/1 nighttime operation: We conducted 3 Operations.

3rd:CW:S3[dB] FM:S6[dB] Digi:–[dB] Battery Voltage:3.838[V]
4th:CW:S-[dB] FM:S7[dB] Digi—[dB] Battery Voltage:-.—[V]
5th:CW:S0[dB] FM:S-[dB] Digi—[dB] Battery Voltage:-.—[V]

3rd:CW運用を行いバス電圧3.838[V]を確認後,testFM(FM:AFSK(1200bps/437.525MHz))を行いました.
4th:testFM(FM:AFSK(1200bps/437.525MHz))を行いました.
5th:CW運用を行いましたが,ノイズが多く電池電圧の確認の確認には至りませんでした.

3rd:We have confirmed battery voltage 3.838[V], we have operated testFM(FM:AFSK(1200bps/437.525MHz)).
4th:We have operated testFM(FM:AFSK(1200bps/437.525MHz)).
5th:We couldn’t confirm battery voltage for noise.
