ARISSat-1 active in test mode

Some early reports out of S. Africa and Japan indicate that ARISSat-1 is active in test mode. This should include SSTV, Voice Telemetry, Data Telemetry. Doubtful that the Linear Transponder will work due to no external antenna available for the input (RX). The system should be active until 1400 UTC on Sunday (July 31).

NASATV mentions ARISSat-1

If I am not mistaking.. Late afternoon today on NASA-TV made reference to an EVA ARISSat-1 was mention by the NASA narrator this afternoon for Amateur Radio operators. Not that I am attentive to NASA-TV 24 hours, I do have a DTV system dedicated in the shack. If I were only hearing things... MY APOLIGIES...

ISS callsign changing?

Hi, Can anyone explain why the ISS changes it's ARPS from NA0ISS-4 to NA0ISS-3 at random? I'm sure many are beaconing with the wrong callsign in because the ISS has gone from -3 to -4 and back again nilly willy.

Any help/explanation apprecated.....Cheers Dave G7UZN

Setting up SATGATE

Is there specific info on setting up a SATGATE server. I run a Tier-II APRS Server and would like to assist the SATGATE system if possible.

End of an Era: Visually observing ISS and Shuttle flying in formation


At 0839UTC, observing from Barbados, I saw what is, in my opinion,...The ninth wonder of the modern World....

Saw both the Shuttle and the ISS, flying in formation. Just a fraction of a second apart, but both dots of light clearly visible.

ISS was shining brilliantly. Almost as bright as Jupiter (which it appeared to pass close to from my viewing location). The shuttle was leading it by just a half, or quarter of a second or so.

Perfect view for the first half of the pass. The second half, from the highest point all the way down to the horizon, was obscured by cloud.

ISS Repeater - Any NASA folks here?

I read a previous post regarding the repeater, and got to thinking:

If the issue with mode switching from packet to repeater has not been occurring simply because the present crew are unaware of how to do so with the equipment as it is now configured (as someone suggested in the earlier post)... might I suggest:

Does anyone with a NASA connection have a means of communicating to the hams who are due to board in the next few waves of crew swap-outs to express the interest in having the repeater station activated occasionally? An e-mail address for the oncoming crewmembers, even?
