Oscar 11 har i mars i r varit uppe i rymden i 20 r, och den fungerar fortfarande! AMSAT-UK skriver mycket om detta, bla. kan man f ett special-QSL.

NO-45 digipeatern på
Info om NO-45:
The NO-45 digipeater remains on. User are requested NOT
to use the Bulletin Board. When the Bulletin Board is used it effectively locks out ground access to the spacecraft CPU.
Everyone is welcome to use the digipeating/APRS features of Sapphire, callsign KE6QMD, as per the user service agreement located at the following URL (se nedan)
There will be occasional dropouts caused by the CW beacon, and Users are advised to expect extra packet chatter during West Coast (USA) passes, as some schools are using Sapphire for operations training.

Rapport från årsmötet
Idag den 14 mars var det rsmte i AMSAT-SM. Infr ca. 20 deltagande valdes den nya styrelsen, som bestr av samliga medlemmar frn frra ret.
Det var allts inga verraskningar p rets mte utan samtliga punkter p dagordningen gick igenom.
Under vriga frgor blev det en liten diskussion hur man skall locka nya, och framfrallt yngre, medlemmar till freningen. Thomas Lindblad freslog en medlemsvrvnings-kampanj av ngot slag, tex. att ka ut till skolor och bertta om vr hobby.
Sven Grahn, knd frn TV och radio , hll sedan ett kort men bra fredrag om satelliten SMART-1.
En fungerande modell av Victoria fanns ocks p plats men tiden rckte tyvrr inte till fr en demo av denna.
Bilder frn rsmtet finns p rsmtessidan.

Vissa livstecken…

Today during the period 0310 to 0320 UTC (orbit 1541) I observed the following.
Prior to issuing the command sequence we tune around the beacon frequency, taking note of the noise spectrum . No variance in amplitude detected, just clean white noise. At 0310, commenced sending a 12 block sequence, 3 * (Reset,Tx-Off,Reset,Tx-On).
At the completion of the sequence, again tuned around the beacon frequency, and noted a noise peak of 4 to 5 db, in the vicinity of expected beacon frequency. The width of this peak was about 5 kHz. Listened to it for about 15 seconds and then sent a Reset, Tx-Off command and the noise peak disappeared, approximately 2 seconds after the Tx-Off block was completed.
Completed my session with a number of Aux-Batt commands, but did not attempt the Tx again. Range was nominally 12000/15000 kilometres during command period. Was using my last calibrated uplink frequency.
This tends to suggest that the IHU and L Band Rx are operational. Bus voltage insufficient to open that damn relay. Considering SA=-72, the remaining cells are holding up well. Hope this makes your day, like it has mine.
