Hi All, I didn't really know who to contact, so I emailed you all, sorry for
the spam.
I'd like to officially inform the Amsat and IARU communities (though you
surely know this already), that we are now sure CubeBug-1 is object 13018D /
39153.
In the last days NORAD has officially assigned the name "CUBEBUG 1" to
object 39153.
Doppler shift analysis made by many members of the amateur community (via
private communications) agree with this too. For example see
http://www.dk3wn.info/p/?p=33101.
Finally, our own analysis, and that of the launch services broker
(ISIS/ISL), based on insertion forces, masses and other physical
characteristics, agrees with this assignment.
So we wanted to inform the community that we now officially assume the
CubeBug-1 is object 13018D/39153 and that the frequency of the radio has
shifted, for some yet unknown reason. We now assume the satellite transmits
(and receives) at 437438300Hz. This again is mainly based in the experience
of the members of the amateur radio enthusiasts.
And finally, but most important, we also wanted to thank the whole radio
amateur community, so please forward them our most warm thank you. I tried
to put what I feel in words a few days ago:
http://1.cubebug.org/post/49490931912/we-love-the-amateur-radio-enthusiasts
thank you very much all for being there,
gera for the CubeBug-1 team.
PS: Please, forward this email to who you think may be interested, thank
you!

I wouldn't recommend a J-pole for satellite work unless you expect to
only work sats on the horizon. The J-Pole antenna has a low take-off
angle and almost NO radiation overhead, an plain 1/4 wave ground plane
antenna would work better for the sats.
J-poles are great terrestrial communications antennas, not so much for
working overhead satellite passes. An Eggbeater or quadrifiliar antenna
would be a better choice.

The AMSAT-UK page at http://amsat-uk.org/2013/05/12/hamtv-from-the-iss/
provides the links, they are:
Facebook https://www.facebook.com/Hamtvproject
More information at http://www.amsat.it/Amsat-Italia_HamTV_brochure.pdf
and http://www.amsat.it/Amsat-Italia_HamTV.pdf
The HamTV.pdf gives the link budget, looks like there's 7dB of
coax/connector losses to overcome between the ISS transmitter and the
antenna. That document indicates a 90cm dish should be sufficient.
I believe that it's going up on ATV 4 which is currently slated for June 5.

I understand the HamTV equipment will be carried to the ISS on the ATV 4
spacecraft currently planned to launch on June 5.
BTW Italy also has an Astronaut Luca Parmitano KF5KDP heading to the ISS.
Luca is planned to launch from Baikonur in Kazhakstan to the ISS on May 28

Anybody off the top of their heads know how many degrees a second swing
are (is?) required for direct aim at the ISS? I know there are beam
width tolerances, altitude variations and degree above horizon
variations but I'm looking at Bob B's fixed antenna aiming of 15-20
degrees above horizon to evaluate swinging a dish without torque eating
up the drive train...

A dish like in the picture probably has a beam-width of 15-ish degrees.
I used a 30 inch BBQ grill antenna for AO-40, and would notice a
drop-off when mis-aimed by about that much. ISS moves VERY quickly
compared to AO-40, so some sort of active positioning on both axis is
going to be required.
I need to get that dish back up on the rotisserie...

HAMTV stream will be transmitted at 1.3 MSym/s or at 2.0 MSym/s.
Technical specs of the set-top box indicate the range of the decoded
stream. Generally this range is from 2 to 45 MSym/s, therefore if you
need to buy it, you should select one that can guarantee a range from 1
to 45 MSym/s.

Hi Emanuele,
Right. But what is that in terms of what normally gets described? For
example, I have a Digital TV card for my computer (Pinnacle PCTV HD).
It says it does "ATSC digital TV (HDTV up to 1080i, and SDTV)" and
"Clear QAM (unencrypted digital cable)".
Am I even close?

Hi Greg,
I believe that your Pinnacle PC Card is not for DVB-S (Satellite
networks) but for DVB-T (terrestrial networks).
Please check on the web or give me the model of your card, so that I
will check it.
