Austronauten Bill McArthur har varit ganska aktiv från ISS den senaste tiden. Läs mer:

Trevor M5AKA ger oss följande info om ISS i helgen:

This weekend (Jan 14-15 UTC) International Space Station Commander Bill McArthur plans to operate NA1SS on 70cm exclusively using a frequency of 437.550 MHz FM

Flera väl fungerande Polära satelliter att köra (tyvärr så saknar vi ju fortfarande en riktig DX satellit men väntar på P3E)

Körbara
AO-7 (mkt mode B)
FO-29
SO-50
AO-51
VO-52
AO-27 (Semioperational)

Hi All,

We have received a report from NORAD that they have recently detected an additional object in an orbit which is very close to SSETI Express.

It is possible that this could be NCube-2 which should have been deployed from Express just after launch on October 27th.

It would be really good to see if signals from NCube-2 can be detected on 437.305MHz +/- Doppler.

NORAD will be cataloging this new object as 28897 and an element set should be forthcoming shortly – in the meantime the existing SSETI Express TLEs/Keps will be accurate enough.

AO-40 Update – 9 March 2004

Gentlemen,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 ok.

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.
