[運用結果]/[Operational results]
2015/1/10 夜間の運用を2パス行いました.
2015/1/10 Nighttime operation: We have conducted 2 operations.

4th:CW:S4[dB] FM:S12[dB] Digi:–[dB] Bus Voltage:3.785[V]
5th:CW:–[dB] FM:S3[dB] Digi:–[dB] Bus Voltage:-.—[V]

4th:CWにてバス電圧3.785[V]を確認後,FMダウンリンク(437.525MHz/AFSK)を行いました.
5th:引き続き,FMダウンリンク(437.525MHz/AFSK)後,SSTV(437.600MHz)を行いました.

4th:We confirmed bus voltage 3.795[V] by CW operation. After that we have operated FM downlink(437.525MHz/AFSK).
5th:we have operated FM downlink(437.525MHz/AFSK) and  SSTV downlink(437.600MHz).
