Hi Les (and others)
I haven't used 6.0 but almost every version before that.
When you just want to listen to the sats, it is a great peace of
software
but when you also want to transmit via the sats and be able to control
your
uplink via de software, then my experience is, that is a pain to work
with
the VFO sliders.
If they would change the way the frequency can be changed I would use
it more
often.
Now, after trying them all (Nova, Orbitron WXtrack, etc etc),
SatPC32 is my preferred software for working the Sats.

How is Nova's ground track display better than the one in SatPC32, which
displays the ground track of the next orbit?

I am not sure that I would count any Satellite out when it comes to
emergency use... especially if I lived in some remote part of India. Or any
where else that was remote. I think Gilligan and the Skipper would agree
with me. That this resource may not have been used for this purpose at this
point does not mean that it won"t in the future. Me, I will sleep better

Les
I'm using HRD 6.0 SAT Tracker/HRD Rotator as well as SATPC32, predominately
HRD SAT Tracker.
In fact, I was using SAT Tracker when you and I QSO'd 5/20 on SO-50 .
I use them in conjunction with my Flex 5000A / EA4TX rotator controller/
G5500 rotator.
I am only using SAT Tracker and SATPC32 for TX/RX Doppler control as neither
product has adequate support for other Flex 5000 Rig control functions IMHO
.
I have written software which intercepts CAT commands coming from either
program and I only pass on doppler tuning info through to the Rig.
The same software allows me to do other required Rig control functions:
-TX
-TX/RX calibration for transponder satellites
-RIT
-Transmit power adjust
-Satellite specific controls-TX/RX mode, tones, reset SO-50 timer,
etc.
I also have provided support for my TS-2000 and IC-9100 in the software.
My preference for SAT Tracker is primarily because I like the user interface
better.
Some caveats on using HRD 6.0 SAT Tracker/HRD Rotator natively with any
supported rig:
HRD Rotator does not play nicely with Rotators with a south stop
(Yaesu-5400), you can make it work, but software azimuth readout is 180 deg
off
HRD SAT Tracker does not support transponders of the "Non-inverting type"
(like AO-7 mode A)

Les,
I love satpc32 and used the free edition for a while till I could register,
and I'm glad I did. Thanks Erich
It runs a 5400 rotor via a W9KE - TI MSP430 rotor interface. Thanks Tom
I have used the others, but I use satpc32 and have "configs" for:
Config 1
Icom 910 - for modes B or J
Config 2
Icom 9100 - for modes A B or J
Config 3 (backpack rig)
Icom 703 w/2m xverter Ten Tec - for modes A B or J
Yaesu Ft-817
Thanks,
Mike

Sorry Domenico,
the link you provide is on the "old" Amsat-NA website and is a copy of the
Indian website:
http://www.amsatindia.org/hamsat.htm
Nothing more, nothing less and Bill's point is very valid. While amateur
radio has a great history of emergency services and is one of the true key
public services, amateur radio satellite are currently not part of it. That
does not mean they cannot be used, but they are just too limited. There is a
reason why 99.9% of emergency services within NA using amateur radio are
based on ground services trough VHF/UHF and HF and not satellites!

If you you mean that the the "emergency" access ability used
by AMSAT as part of the justification for funding or launch
vehicle access it doesn't mean it works for that in any practical
situation it is like to say that AMSAT tells falsehood to NASA
and ESA but as far I know AMSAT is not used to talk nonsense.

Thanks!
However you still seem to be missing the point.
First of all, these are incorporation papers from 1969!
Secondly, no one questions the potential of satellites and their actual use
for emergency. We actually have "satellite phones" for emergencies in our
facility and use them when we deploy folks around the world. Satellites
make great emergency communication systems if and I reiterate IF they are
available 24/7 365. Unfortunately none of "our" satellites will ever meet
that requirement unless we are in a fixed location on a geostationary orbit.
Thirdly, current amateur satellites are only available for a few minutes
sometimes during the day and our provincial/federal emergency coordinators
are having a good laugh about that.
Fourthly, please look up ARES and RACES on the Internet. Biggest emergency
response groups and networks worldwide involving amateur radio. None of
their frequencies include a single satellite for obvious reasons.
Rest my case.

It's a bit dated now since I wrote it in 2008 for a Symposium paper
and it was reprinted in CQ VHF magazine ... I wrote a paper about
satellites in EMCOM:
I still have a copy stashed at:
http://home.comcast.net/~k9jkm/CQVHF_Eagle_ACP_Emcomm.pdf
This paper assumes a few things like we have an Eagle Phase IV GEO
satellite. It is written to tie multiple components of a national
level incident command system response up to being able to allow
several incidents to communicate with a unified command at a national
level. While the intrepid ham with HT and go=pack is key to local
emergency response a GEO satellite wasn't what was needed to call in
tornado reports within the county.
Now Clayton can really sleep better after reading this! Probably fall
asleep reading it, but ahem, I digress ...

Thanks to Dave, and many others who contacted me about the use of
Satellite Tracker in HRD 6.0.
It was exactly the kind of input that I was hoping for.
A couple of other questions:
1.) I've noticed that Nova for Windows and SAT32PC display slightly
different data regarding AOS, LOS, Azimuth and Elevation for a given
satellite. This seems strange to me
since they're using the same KEP data, share the same PC clock which is
synced every 12 hours, etc.
Anyone else notice these small differences? None of them have much
effect on actual operation which is governed by the beamwidth of the
antennas (pretty broad), objects
blocking the horizon, etc. but it does make me curious.

I thought the whole idea with these SDR "Dongles" is that you could
decode practically anything in software. Unless the required bandwidth
is too high, and perhaps not in real time, but they can be decoded. For
example, people do SSB and FM with them, neither of which are anywhere
close to DVB-T modulation.
Couldn't something like that be done with HamTV?
