Yes full duplex is a must for working linear sats. If you already have an
FT-857 you've already got the "hard part", generating SSB on 70 cm, sorted.
All you need is a separate receiver.
A $20 RTL2832-E4000 TV Dongle would appear the cheapest way of achieving
that, see http://www.youtube.com/watch?v=kTh4DAmMzrM
I've never used that dongle myself but it may well provide sufficient
performance to receive a 2m satellite downlink. Has anyone used one to
receive amateur linear sats ?

On September 15-16 Dr Chris Bridges will be giving two presentations to the
AMSAT-UK International Space Colloquium at the Holiday Inn, Guildford, GU2
7XZ, United Kingdom.
Chris will cover the Nexus Android Smartphone amateur radio satellite
STRaND-1 which will carry both a Resistojet and a Pulsed Plasma Thruster
(PPT) module and STRaND-2 which will use Microsoft Xbox Kinect controller
technology.

There is no problem receiving the linear sats with the Dongles. The
dongle offers a big advantage in that you can see the whole 'band' at
once and spot people very quickly. SSB and CW reception is great. The
doppler correction with SDR-Radio works as well as the gold standard
SatPC32.
The extIO stuff for the cheap dongles are still in the early stages
and very geeky but they do for the most part work. The FCD is a much
more mature product so I have been working with that and waiting for
the other dongles to catch up.
Problems with integrating with transmitter control remains. SDR-Radio
links with external radios but I have been unable to figure out how to
offset the transmit frequency. I am currently working with HDSDR and
controlling it with and none other than SatPC32. HDSDR appears to be a
bit more flexible interms of connections with other gear. Omni-Rig
support is built into HDSDR and works great but has the same
limitations as SDR-Radio external radio control.
The other problem which is not as difficult is the front end overload
problem with the dongle. The sensitivity of the dongle is excellent
but the front end selectivity is almost non-existent. Filtering is
necessary and even with a 70 cm tuned cavity I am still having desense
that makes hearing the downlink difficult.
I am close to a SatPC32 <-> dongle system but there is probably
someone with a much better 'simple' or even a 'very simple' solution.
I would be very interested in hearing from anyone who has actually
achieved fully synchronized doppler corrected transmit control with a
dongle for the receiver. A reply offline would be best to prevent
flames.
As Steve Jobs liked to say "Just one more thing". The new AMSAT store
looks great. Take a look if you have not seen it. Thanks to those who
built it and thanks to Martha for keeping things going while it was
down.

Hi Tom,
There will be an article coming up in the AMSAT Journal on work that W1GHZ,
W1FKF and I have done on tapping the common IF in the FT-817 and using the
FunCube as a Panadapter. Our primary application is weak signal microwave.
I would think it would work well for satellite. That way your software would
be controlling an FT-817. The common IF is centered on 68.33 MHz in the
FT-817, so you see +/- 40 kHz around that. You would be able to take
advantage of all the front end filtering in the FT-817.

Hi Mike,
I have two radios that have a built in panadapter and have used the
dongle as a stand alone panadapter. The problem is all the panadapters
I have used or read about, other than SDR based gear like the Flex
radios, do not have a connection between the panadapter and the
frequency control of the radio. With an SDR receiver you click on the
waterfall or spectrum display and the radio is tuned to that
frequency. That is what I am trying to do and that bit you get for
free with an SDR receiver the hard the part I am trying to solve is
controlling the transmit frequency (including doppler correction and
offset) when using linear sats. The only way I have been able to do
this so far is to use SDR-Radio with its built in doppler correction
for the receiver and my IC-7000 as a transmitter under the doppler
corrected frequency control of SatPC32. This works but changing the
frequency on the SDR does not adjust the transmit freq. I am hoping
someone has actually done this as I have never been a big fan of
reinventing the wheel.
The FT-817 is a very cool rig and I will be very interested to see how
you control the FT-817 frequency from the panadapter - that is the
tricky bit since the panadapter does not have to even know what
frequency you are receiving. It should be possible to poll the
panadapter for the offset of the frequency you have clicked on and add
that to the FT-817 frequency and feed it back into the FT-817. I am
sure you guys have come up with something. Thanks for writing the
article. I look forward to reading it.

Hi Tom,
The "uplink" connection in the panadapter seems to be the missing piece
right now, but truthfully, I have not looked lately to see what's available.
I can tell you that HDSDR and Omni Rig work well with the FT-817 and the
FUNcube. In HDSDR, the tuning controls the FT-817 (and tuning the FT-817
manually updates HDSDR) and behind the scenes, HDSDR locks the FUNcube to
68.33 (or whatever you set it to use - I use 68.32 to get away from the DC
offset spike). But, no doppler control.
I guess if I were going to do it, I'd tap the common IF of my FT-847. Then
use SatPC as usual to control the 847 and HDSDR to just display the FUNcube.
I wouldn't have full integration, but I'd be able to see most of the
passband and could simply tune the 847 to receive the downlink. SatPC would
compensate for uplink Doppler.
I could probably do the same with an FT-817 or two of them....
Having the ability to see other signals in a +/- 40 kHz window (for those
weak signals off frequency) was the big plus for us working microwave and I
could see it being a big help in satellite work as well.

http://tinyurl.com/amsat2012
We are pleased to welcome senior representatives from AMSAT-NA, AMSAT-DL
and AMSAT-SA
who will be giving status updates on their respective development
programmes.
There will be an update on the FUNcube project as well as some real-time
demos of the
Engineering model.
There are some other surprises in the programme, so please take a look.

Hi,
Two ways were mentioned to run old programs with windows 7:
1. Windows 7 Pro or highrer, working in its built-in "Windows XP mode"
2. Windows 7 Home (the cheaper version of Windows) with XP (or older
Windows version) installed.on a virtual machine.
Does anyone know if WISP will work in both cases? even if Windows 7 (either
Home or Pro) is installed in 64 bit version?
thanks & 73
shamai, 4z1ws
This solution seems cheaper than installing Windows 7 Pro.
Will it run WISP and other old programs as effectively as the "Windows XP
mode" in the more expensive Wi ndows 7 versions?
