At approximately 1800z today, I had a nice high elevation ARISSat pass, and
again tried out the SSB transponder.
I easily heard my uplink while calling CQ a few times. I was pleasantly
surprised when Bob, K9OIM in EM56 answered me. The QSO was very brief, but
exciting.
I wonder if anyone is keeping a tally of contacts made using the ARISSat
transponder? Or are there just too many to count?

Hi,
At a new QTH and? setting up a dual band quad antenna for 2m and 70cm.
I plan to make the 70cms antenna,the vertically polarised?one, ?2m horizontal,
as?I believe this is the normal arrangement.
If anyone has practical experience that goes against this assumption I would
be
interested, either direct on on the bb.
I don't have polar phasers, switchable delay lines or anything else its just a
straight choice, which one goes vertical.
They are on the same boom so?I suppose I could go slant for both ?
Main activity here will be phone, VO-52, AO-51, FO-29 plus satellite telemetry
from cubesats etc.
Thanks in advance
John

I was visiting FN95 on my vacation; beautiful hilltop with about nearly 360
degree visibility. I first caught a 30-degree elevation using my F6A with
stock rubber ducky. I had to twist it around a bit to find the right best
orientation (horizontal this time) but I got a nice signal the entire pass.
I hope I have recorded some SSTV that I can decode once I get back home.
That will be cool!
Next orbit (about 23:58Z Aug 29) it went directly overhead (or close). This
time I happened to hit the greeting in English, which was clearly audible,
although I did not get as much SSTV. I probably wasn't tweaking the doppler
enough or getting the orientation right.
Bonus: ISS came over 5 minutes later and I got to ooh and aaah our friends.
Now that I have a few things that work, I can eliminate some of my sources
of trouble at the home QTH, and hopefully get the signal back where I have
the decoding software etc set up!
Whoo-hoo! This is fun! And the telemetry sounds like the solar panels are
holding up well even if the battery did not!

Oh, Burns - think of the conversations you would start if you reached into
your duffle and whipped out a tape measure beam - and started to un-furl the
elements for all to gawk ...
(No - I did not take such on our cruise ... But I sure THOUGHT of it ...
(grin))
Although ugly, Kenwood put a lot of money into that tri-band antenna that
comes with the TH-F6a. It is one of the better multi-band
stock ducks.
GREAT JOB!

Content-Type: text/plain; charset="us-ascii"
Hello everyone,
This morning I had a good pass of ARISSat-1 over Hanoi, Vietnam and decoded
its BPSK-1000 for the first time. According to ARISSatTLM, more than 30
frames were sent to the server out of more than 60 decoded. Manually tuning
the CW signal to keep it within range is fun and it was audible until the
satellite was 1.5 degree under the horizon. Maybe next time I'll try the
transponder :)

The FM telemetry downlink was initially acquired at 0014 UTC with the end of
the SSTV transmission. The signal was barely audible.
Transmission resumed at 0016 with S9+ strength, no noise, and the following
details:
- ID
- Greeting in English
- Secret word
- MET = 45 minutes
- IHU temp. = +31 degrees C
- Control panel temp. = +31 degrees C
- Battery voltage = 35.70 V
- Battery current = -24 mA
The CW beacon was not heard.

I'm on the hook for an amateur satellite presentation next week to the
Vashon Island Amateur Radio Club (http://www.w7vmi.org/) and am hoping
not to reinvent the wheel. Pointers to favorite amateur satellite
presentations in .ppt form which can legitimately be re-purposed for
this effort would be appreciated.

Hi Giulio, AB2VY
Edusat is a "Non amateur satellite" ? ......OK ,but it has received an
experimental license on 435.750 MHz for communicating at no cost
into the "Satellite Amateur Frequencies" without coordination from
IARU..OK ?
It is very strange that Edusat has received an experimental licence
for communications into the Satellite Amateur Band without a
frequency coordination from IARU
It is also very strange that the GAUSS group do not officially published
the operating frequencies of Edusat stating that those frequencies
published via internet are wrong frequencies.
It seems that there is no coordination between our Communication
Autority in Roma and IARU as well between the GAUSS group the
IARU and the Radio Amateur community.
In conclusion dear Giulio Edusat is a satellite not of our interest and
please forget the above box for shoe.
