[jamsat-news:2575] KDES が落成検査に合格

みなさま

　勝浦にあるJAXAのパラボラアンテナを使ってEMEなどの実験をする
プロジェクト（KDES)ですが本日無事、落成検査を終わりました。
JH1KRC渡辺さんからアナウンスが流れています（英文ですが）ので転

　私も少しだけ手伝わせていただきましたが、関係者のみなさまのご
努力は大変なものがありました。これからも、新たな周波数への挑戦
などプロジェクトは続きますので、ご興味ある方がいらっしゃいまし
たら、是非ご連絡ください。

Today, October 31, 2008,  8J1AXA, Katsuura Dish Experimental
Station (KDES) has passed the inspection by the Japanese
governmental telecomm.  and has been licensed 500 watts output
on 144MHz and 432MHz for EME.

By now our first EME QSO was made on 144MHz CW with O/RO
while the moon far in the south this afternoon.
We are requested to experience the interfereence test on 432MHz
which has not been performed before.
As soon as we have this test passed without any trouble, we will
begin operation on 432MHz as well.

Since this station is located inside the JAXA Space Communications
 Center, which is presently operational, severe requirement 
on the spurious suppression and time sharing are needed (so that 
we have no worry about any possibility of  deletion of a bit of 
the data they handle).

All the transmitters/power amplifiers already satisfy the harmonic
 suppression of -80dBc.
