[jamsat-bb:12744] AO-40 Update, 2003-01-01]



AMSAT−BBから転送します。

K−TXが昨日から稼動開始されました。
その間、MA126−128はU/L−>Sのトラポンは停止します。
なお、前回K−TXの最後が一時的に出力が不足しゅる事態が報告されて
いましたが、今回どのような状態か、問題有り無しにかかわらずレポートを
AMSAT−BBに送付してほしいと呼びかけています。
なお、前回JH1UGF槙岡さんの報告によると、周波数がいつもとちがって
急激に下がって行き、消滅するような状態だったとのことです。

The AO-40 schedule has been modified to activate the 24 GHz K-band 
transmitter.  From MA 126 to 128 both the S2 and K middle beacons only will 
be active.  From MA 128 to 132 both the S2 & K transmitters will be active 
on the U/L uplink passbands.  The last time the K-Tx was active, it was 
noted to have suffered a partial power loss suggesting that one of the 
output transistors may have failed.  We will monitor its function to see if 
this condition has changed.  Please report your successes/failures to the 
amsat-bb.  We are holding ALON/ALAT at nominal 0/0, but ALAT has been 
drifting slightly positive (~1 deg), which will slightly favor northern 
hemisphere users.
