Don't worry too much about it, John.  SO-50 is one of those FM analog
satellites you detest vehemently.

Hello everyone and greetings from Guatemala, I will try to be more active on
the SO-50 passes around Guatemala EK44SL
so please look for me, I will try tonight a pass that is around 0530z and
tomorrow around 1800z.

Current setup is an Arrow VHF/UHF antenna and the Yaesu FT-60 5W handheld,
also from my home base an FT-7900 with 50W
but with a VHF/UHF vertical antenna (I know is not the ideal antenna but I
can try).

Any comments, suggestions are more than welcome.

Thanks and 73

Juan

Dear David-san,

Hello, Thank you for your mail.

We think the remote transmission of digi-talker message from small cubesat
is purely one of the technical challenges for us.
And we also think "stop the war" / "world peace" is a natural message as a
citizen on the earth.

But if many people in this community think it is political and breaks the
rule, we will stop sending them ASAP.

All the best,

Akihiro Kubota

Hi,

For a digital bird with a 10 GHz downlink, would it make sense to use
DVB-S for the downlink?

If you did, I think that most specialised part of a ground station would
be an appropriate LNB that will mix 10.0 to 10.5 GHz down to IF.
Demodulation could then be performed with ordinary consumer grade DVB-S
set top boxes and PC based DVB-S interfaces.

Out of the box, a consumer DVB-S STB (Set Top Box) can handle both audio
channels and video channels. The DVB-S protocol can also multiplex data
(PBBS message forwarding? APRS?) along with multiple audio and video
channels on the one carrier.

The satellite could have multiple uplinks on multiple bands, eg FM voice
uplink(s) on 2m, 9k6 data uplink on 70cm, and video/high speed data on
shorter wavelengths. So, with say a 2m mobile rig, and a consumer DVB-S
setup (with a 10 GHz LNB) you could QSO via the bird. If you want to get
into data, video or digital voice, the bird would do that do.

Ross,


You may be wish to watch the presentation to given by Peter Guelzow DB2OS at
11:20 BST (1020 GMT) on Sunday, July 27.


Peter will be talking about the equipment required to work the new amateur
radio Geostationary 2.4 to 10 GHz payload which may be launched in 2016.?
Es?HailSat-2 will provide a 250 kHz linear transponder intended for
conventional analogue operations in addition to another transponder
which will have an 8 MHz bandwidth. The latter transponder is intended
for experimental digital modulation schemes and DVB amateur television.
