ARISSat-1 Silent? (& Request)
*Hi All, I was listening on the 145.95 Voice telemetry Beacon Freq. @ 1310 UTC pass here in ENY & didn't hear a peep from ARISSat-1 , & was wondering if it has gone silent? My Grid Square is FN31! 73,.Stu (WA2BSS) PS (a request) Was wondering if someone has a Duplexer? *IE a Box, on 1 nd is where the Coax gets connected, & on other end is 2 short coax cable lengths; & 1 length goes to 2 meters; & the other length goes to 70 CM1) (I have a Kenwwod TS-2000) *
Hi Stuart, As of right now, ARISSat-1 is up. Telemetry has come in from multiple ground stations within the last few minutes.
Depending on the orbit, there is often a delay between the time when ARISSat comes out of eclipse and the time when it starts transmitting telemetry. If anyone in the satellite's footprint is running ARISSatTLM and sending telemetry into the Internet telemetry server, then the telemetry web pages will get updated (within about a minute). Note that sometimes the orbit takes the satellite out over the Pacific and over areas of the world without any active ground stations (that receive the telemetry), so it can be two or three hours before ARISSat-1 goes over another groundstation that is submitting telemetry and hence the web page could be two or three hours "old" and that does not indicate a problem.
The telemetry web pages are at

and

14:50 UTC - 9/29/2011 ... I'm receiving ARISSat-1 very strong over Orlando. Reading the voice ID, voice TLM, SSTV and messages with little fading on a ground plane with preamp.

That would be a diplexer, not a duplexer.

There *used to be* a very, very good design, easily build and readily repeatable, on that site. It appears that the site owner has had a hissy-fit over criticism of a "magical antenna" design, and has pulled it down. A spot of googling will turn up a copy of the original article, though, which I won't link to directly just in case HB9ABX gets even more upset. Alternatively you could email him and see if he'll sell you a copy.
