Roger,
A SWAG, (Wild Guess) 1 degree per second at a Zenith of 90 degrees. Anything
less than 90 degrees will be slower with several minutes spent near the
horizon. You can use an orbital program to get exact numbers. With a wide
beam width antenna, the lag overhead may never require the antenna to
Jeff,
You are correct, a J Pole is an end fed dipole on its side. Max gain at the
horizon and extinction at 90 degree elevation. The J section is for matching
and does not radiate. Gain = 2.1 dBi at the horizon.

Ah, that is probably right. Model is PCTV-800i; it's definitely aimed
at terrestrial stuff. Now I know what "-S" means...
Would there, by chance, be a decoder for the FunCube Dongle (or other
USB thingie)?
Thanks for the help,

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.

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?

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.

For the digital TV challenged, what means "Any DVB-S Decoder which can
decode a 1.3 MSym/s TV signal"? How would I know if I have such a
thing, or what I would need to get if I don't.

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

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 communicat

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 ass
Nice!
Has anyone figured out any ground station requirements? Antenna gain,
polarization, receiving equipment etc...

Thank you all for your valuable hints and advices !
I will now build such an antenna and then supply here the results.

Seeing how he is pretty rare, it would be great if people would make the
contact and move on so others can work him, not chit chat about everything
under the sun. Just my 2 cents.

I've getting my CubeSats mixed up - As far as I know EstCube-1 doesn't have a
transponder or digipeater.
I was thinking of CubeBug-1 which was launched with TURKSAT-3USAT. It's
CubeBug-1 that has the Digipeater capability, see

No word yet and personally I wouldn't expect anything for 6 months or maybe
more.
Remember in the case of TURKSAT-3USAT that AMSAT-TR (TAMSAT) are only providing
the linear transponder, they do not own the satellite.
