Hi all,
As notified in this weeks news I can confirm that Paul -2M1EUB/P is active
on the satellites from the Isle of Skye - Scotland.
Once again had the pleasure of making contacts on FM and SSB with Paul from
my QTH in Wales today.
Very good signal and very well managed by Paul even on AO-51 with the
European traffic, however he would still appreciate DX contacts this week from
the Island followed by activation from his usual vacation in the North of
Scotland.
Thanks once again Paul for your dedication and time for these trips.

Interesting thread regarding? MET and ARISSat-1 switch on.
?
Someone made the very good point that the transition in or out of sunlight
(eclipse) is not an on/off event. I remember many?MIR visuals, and as she
passed
from sunlight in the west to darkness in the east there was a significant
time,
perhaps a minute or?more when she changed colour from bright?and?silver
white to
orange then disappeared into blackness. I always interpreted that as passing
through the penumbra, or semi shadow area.
?
ARRISat-1 is at at around 370km, does anyone know how to find the width of the
penumbra ?at that altitude?
Working out the transit time through that region might be informative.
?

Using Orbitron 3.71 software, I can tell that the penumbral duration today
was 9 seconds. However, this will vary in the future as the angle of the
orbit to the sun changes. However, the first sunlight the satellite will get
will be very red (due to the blue light scatter caused by the atmosphere). I
have observed that ARISSat-1 doesn't start transmitting for a further 14
minutes.
To be more precise, I am seeing the Mission Elapsed Time (MET) counter start
counting from zero about 40 seconds after coming out of eclipse, and the
first BPSK telemetry frame has a MET=808. The first KURSK experiment data
isn't transmitted until MET=945. However, since 12th September the KURSK
experiment appears to have failed and is only sending null data.

Does this bulletin board have a 'files' section like a Yahoo Group? In a
Yahoo Group, that can be done and questions that are recurring can be stored
and a new questioner can be referred to that file, if no one is inclined to
answer the question.
If not, maybe its time to make the AMSAT board a Yahoo Group that would
still be moderated. HRD, Kenwood, Yaesu radio groups do it quite
successfully
(assuming someone's Sacred Cow is not stepped on !)

The bulletin board system AMSAT is using is well suited for information that
is useful for only a relatively short time. If there is a trip to a rare
grid location that information is of little use after the event takes place.
IMHO what is missing is a way to share information that has relevance beyond
a few days.
When I became active again on the sats I asked a question on the board. I
received an email telling me that "that question has been asked several
times before". It was helpful beyond belief.
In the last few days someone posted a nice check list of things to do to try
and get your SatPC32 station running. A bit later someone posted a
correction that added a vital step that was missing in the first posting.
Suppose a newbie subscribes to the board today - he has already looked at
the articles from 1997-2004 in the new users section on the AMSAT website
but needs a little current info. He posts a message on the board asking
about getting his SatPC32 station working. Lets hope no one sends him a
message telling him that "that question has been asked before". I also hope
no one sends him a message suggesting he uses the search function. That
would
be like the 4th grade teacher who responded to my question "How do you spell
pneumonia ?" - by telling me to "Look it up in the dictionary" - I spent a
lot of time looking for words that started with "N" before asking my folks
when I got home.
If they did search - what would they look for. What are the chances that
they would find the initial post AND the correction post. I realize
everything is perfect as it is but perhaps it would be nice to have
something similar to the Yahoo Groups where subscribers can post files and
pictures of things that would be of interest for more than a day or two.
Take a look at the SDR-Radio or Softrock groups on Yahoo. There are files
and pictures that have been very helpful to me. There was a recent posting
here from someone asking for a current Doppler.SQF file. I sent him mine but
it would have been better if there was a place to store it where anyone
could access it.
Some people have their stations working well but are not all that excited
about spending a lot of time documenting it and posting it for a handful of
people who might look at it before it disappears into the abyss of the
message archive.
You may not like what you read but be thankful I fought the urge to include
some sort of Jonathan Swift reference.

Here is a useful Google trick that not everybody knows about:
In your Google search you can restrict your search results to a specific site
by using the "site:" specitication. To search amsat-bb use
"site:www.amsat.org/amsat/archive/amsat-bb" and then the string you are
looking for. For example, to search the amsat-bb archives for references to
SatPC32 type in the Google search box:
site:www.amsat.org/amsat/archive/amsat-bb SatPC32
To search for references to the G5500 rotor use:
site:www.amsat.org/amsat/archive/amsat-bb G5500

Over the past couple of days I've heard ARISSat once. Even on the really
high passes (up to 27? on the highest ones) there's just been not a cheep
out of it. It must be in full daylight, too.
Has anyone else heard it? I notice my tweetly noise is still there on
145.919MHz, still no idea what that is. It seems weaker today, but maybe
that's a weather thing.

Hi all,
I got 3 good passes in today (all in sunlight). The first was
interesting. The satellite must have been tumbling still as the signal
was up and down (this is not unusual).
In a single pass though I'm sure I got 'high power' telemetry, then it
suddenly died, followed by 'low power' telemetry. The satellite was in
Sunlight the entire time.
I would say the battery is not even acting as a capacitor anymore. The
unit must have made a power decision as it rotated through different
sunlight angles perhaps?
However indeed it is still working.

I copied the 08:30 utc pass over Italy and the signal was audible at 08:36,
so 15 minutes +o- after the sunlight.
I heard at 145.950 FM voice, TLM and SSTV

As reported over the weekend, Arissat-1 is no longer audible in the UK,
because she does not switch on until after about 14 minutes from entering
sunlight.
?
I believe the sequence is:
?
enter sunlight: MET starts: timer activated
14 minute wait before tx - other systems live
Tx on with data at a MET of 14 minutes
Tx sequence
?
We in the?UK now have to wait unril the orbit continues to precess to the
late evening (about 10 days' time)

Hi Ken and the bb,
ARISSat-1 heard in south Devon 1080ej this morning 10:00 utc pass.
It didn't switch on until quite late into the pass. Voice tlm gave MET as 16
minutes.
I timed the announcement it at 10:11:16 UTC. (radio controlled clock)

heard your CW transmissions, CQ CQ WB0KFC, then voice CQ CQ Kilo Foxtrot
Charlie.
In your setup what antenna are you using on the uplink. Do you leave your
Uplink fixed and tune downlink or vice versa?
Appreciate your comments and suggestions for best technique to make contacts
on ARISSat-1.. Have received my own transmissions for very very short time
with weak cw return.
Thanks,
