Any ARISSat-1 news/updates from the project team ?
Just a kind request to the ARISSat-1 team,
Via this amsat-bb a lot of early feedback is provided on the satellite. Often new satellites fail shortly after launch, so it is key to collect as much a possible data in these early days. Many people do this already.
However, we also have many questions and report observations, (as an example the high/low power mode switching over VK) without any reply from the project team directly. Btw I have to say that on BPSK topics Phil Karn & Douglas Quagliana are really doing a great job in discussing the results and giving feedback (thanks guys - very learnful !).
IMHO way to much information is still not made available, or scattered around on various websites, sometimes even in articles of magazines ... Last Twitter post (tweet) was on Aug 3. Last News post to www.arissat1.org was on Aug 5.
As an example: I still have no clue on the operational mode switching sequences, like voice... sstv, but also: when will which type of BPSK be transmitted, how long are the transmission sequences, what is the TX off-period.
Please don't take this as an offend, I know we are all very busy. But really, if we want to interest new people - we have to step up and provide more and better information about the mission which was announced so widely.
From a technical point of view the project seems like a big success; the
SDX is working just fine, and we have with a broken (?) antenna still a great uplink capability. Let's celebrate this success and further exploit the momentum that we have now.
Would be a nice start to have a daily summary of which parts of the system have been tested, are working, etc. etc.
Of course, let me know if I can be of any help ! (subject to the US ITAR regulations of course)

Thank you Henk for the observations.
First of all we (being a handful of people) are extremely busy doing many different functions. I was up until 4am working on trying to figure out problems with the experiment data. We just came to a determination about the switching low to high power mode, it is behaving as expected. I will put something out about it soon. I have two teleconferences this morning. I haven't come up with anything exciting worth a news post until today. Do you have something I missed?
The operational FM mode switching is described on the arissat1 site under FAQ ARISSat-1 Signals, http://www.arissat1.org/v3/index.php?option=com_content&view=category&am...
The think the High Power/Low Power modes have been explained many times and places. High Power - Everything is on all the time, Low Power - Everything is on for about 30 secs and off for 2 minutes There are a number of things that I want to improve on the web site, but managing things, writing content and learning the web site are getting done as fast as I can.
The bottom line is only a few people are doing many things.

Dear Gould,
Great to hear&see more content is being added to the http://www.ARISSat1.org website, appreciated !
Regarding news: It would be interesting to hear if the reported telemetry indicates values (eg voltages) as expected.
As I expected, the team's workload is very high, which is a) understood and b) please be assured the work is highly appreciated and we recognize the big achievement made !
Success !
Henk
