D Star satellite?
That sounds like a need idea. Would be nice to do some tests on existing
satellites.
With SO-50 it will not work unless someone has figured out how to have D
Star (DV) active on any D-Star radio with the required tone enabled. Won't
work with the IC-9100. Tried it. Another problem is the 5KHz spacing since
you pretty much have to be right on the frequency on the TX and RX. Also,
on the IC-9100 it seems to be not possible to set D-Star (DV) on the RX and
TX in satellite mode. Anyone else tried it? Also, SatP32 has at the moment
no DV functionality for the IC-9100. I guess we have a long way to go :-)

Stefan,
It appears that stations attempting to work D-Star via
satellite would need to use two radios. This was the
case a few years ago, when AA4RC and N3UC were able to
make a brief QSO on AO-27. You can read about what gear
the used, along with some useful tips for trying D-Star
via satellite, at:
http://www.ao27.org/AO27/
The 5 kHz tuning steps for D-Star radios would make
satellite operating difficult as you mentioned. AO-27
was the ideal satellite for this sort of experiment,
since its uplink receiver was intended for use with
data, and doesn't filter the lower end of the audio
range that it hears. Plus the control operators of
AO-27 have stated clearly that they support and
encourage D-Star on AO-27, something not seen for any
of our other satellites.
>From a quick read of the IC-9100 instruction manual, it
is clear that D-Star was not intended to be used in this
radio for satellite operating or for anything other than
the "normal" D-Star operations (RX and TX in the same
band, simplex or repeater). You could use the IC-9100 as
one of the two radios for D-Star satellite operation as
those guys did for AO-27 a few years ago, but you would
not have access to the IC-9100 satellite functionality.

Thanks!
Yes, will try to put a few suggestions together for Icom for the next
IC-9100 firmware upgrade. It would be a good radio to use next to others.
Have a good weekend,

I occasionally have passes where I can copy myself when the footprint of
either FO-29 or A-07 shows some coverage to extreme North East Australia and
the North Island of New Zealand, but I've never heard any signals from
there.
Are there any operators who would like to try a QSO?

If the new satellite has AFC and a 2m uplink, existing D-STAR radios
should be suitable for the uplink. That leaves the downlink, where I'd
probably use something like an all mode radio with computer controlled
Doppler correction and a GMSK modem with DV Dongle or DV-RPTR board with
an on board AMBE decoder.
Where things could get really interesting is D-STAR allows easy
interfacing to the Internet, so theoretically, you could enable (for a
few minutes!) global connectivity to remote areas.

Actually, after more than 10 years on the market, D-STAR has only about
28,000 registered users worldwide. There are fewer than 2000 active users,
worldwide, daily. Many people are wondering why Icom keeps pouring money
into something which is clearly unsustainable in the long run.
There are very good reasons why no other amateur radio manufacturer will
touch it.

You can read and hear about my first AO-27 DSTAR test transmission made on
September 5 2009. Unfortunately numerous attemps to have
another station to complete a QSO remain unsuccesfull. Some stations where
not able to get to the satellite.
You can hear the audio recording on Matthias dd1us web site
http://www.dd1us.de/spacesounds%202c.html
scoll down to:
Amrad OSCAR 27
(EYESAT-1)
#22825
(1993-061C)
"Usually analog FM voice transmissions are used via AO-27. However the new
DSTAR standard
which is intended to be used via terrestrial FM repeaters can be also used
via satellite as the test
transmission of Luc Leblanc VE2DWE demonstrates. He used an ICOM IC2200 TRX
for
the 436.795 MHz downlink and a ICOM ID-800H for the 145.850 MHz uplink.
Recorded on September 5th 2009 at 22:49 UTC and kindly provided by VE2DWE."
You can also hear the recording on my web page at: www.qsl.net/ve2dwe
(Firefox will not let you hear it IE will...)

What, apart from encryption being illegal on the amateur bands?
Without a radical redesign and a new codec, DStar is just not suitable for
amateur use. Proprietary software runs counter to the whole principle of
amateur radio, and in this case the encrypted proprietary codec is quite
possibly not legal for amateur use.

Hi Georges
I don't remember how long it takes to see AM disappear replaced by SSB but
last week an old ham just telling me how easy it was to tune a
station in AM he just get back on the air with a 21st century radio after a
20 years leave. He's right but the earth still continue to
rotate.
10 years is quite a long run as per our today standards where your PC is no
more up to date after 2 years.
Length of a run appears shorter but not automatically harder when you get
old. Einstein call that "relativity" ;)
I already know 2 hams here up north who just get the new IC-7100 HF/VHF/UHF
Transceiver. Between you and me they surely make some sort of
market survey before as you said "pouring money into something which is
clearly unsustainable in the long run."
My short two cents.

The unique feature of D-STAR for amateur use is that if a user doesn't like
the price, or doesn't like the fact that ICOM is using an AMBE chip, or
doesn't like ICOM because they capitalize every letter in their name, or
because they think that the gubment is going to break down their door
because they are encrypting their signal, or because they don't like
anything new, with D-STAR the user simply doesn't have to use it.
But, if a amateur doesn't like it there is an absolute, gubment-mandated
requirement that he or she tell everyone that cares or doesn't as to why he
or she doesn't like it and/or why they never will.

Furthermore, if I want to use digital voice to talk to someone on the other
side of the world, instead of buying an expensive DStar rig and hoping that
the cobbled-together infrastructure holds up I'll just whip out my phone and
enjoy the greater clarity and reliability of GSM.
I just don't see why having a locked-down proprietary system like DStar is
good. You might as well just use Skype, or mobile phones, or CB.

An interesting idea would be trying a FreeDV QSO via satellite. I've made a
few QSOs with it on HF and it's an interesting mode.
Obviously it's full duty-cycle, so any attempts should be limited to just a
few tests, but I'm sure it would work.
