All mods were performed by me and no holes were done.
This equipment was bought new (1997), and until now
there was not a single problem! It was kept on a non
smoking environment.
Cosmetic is a 8/10 (one minor dent, sort of paint bubble
and 4 rotator control box feet "stain", all on top cover)
Unfortunatly I don't have the original box anymore. Sorry

and Tiungsat-1 with great sucess. I did't use it since
a long time ago, but I belive it's 100% operational.
Cosmetic is 9/10.
I will only sale the 2 items together. Price: 1500 Euro

November should be a great Mobile Satellite Month.
There are 7 satellites you can work from your mobile FM rig,
including PCSAT-1 which should fully recover by this weekend and
last for 2 or more weeks. So now is the time to get going with
live satellite contacts via these easy FM satellites, or setting
up a SATGATE (Igate).
DOWNLINK SATELLITE
-------- -------------------------------------
145.825 ISS APRS digipeater
145.825 PCSAT-1 (recovery expected 3 Nov)
145.825 ANDE-1 (re-entry expected next month)
435.225 GO-32 +/- 10 KHz and 9600 baud
435.300 AO-51 *FM Voice* +/- 10 KHz
436.795 SO-50 *FM Voice* +/- 10 KHz
436.795 AO-27 *FM Voice* +/- 10 KHz
As you can see, there will be over 40 passes per day with 18 for
the 1200 baud satellites, 6 per day for the 9600 baud GO32 and
18 for the voice birds. All 1200 baud pass times are between
about 6 AM to 1800 local sun time in the Northern Hemisphere.
GO-32 and AO-51 voice birds are in the morning and evening,
AO-27 is in the afternoon. It is trivial to know when to
operate these birds WITHOUT A PC. Please see the
manual-tracking page:
http://www.ew.usna.edu/~bruninga/MobileLEOtracking.html
The packet path on 145.825 is VIA ARISS for all three
satellites. The path for GO-32 is VIA 4XTECH and uses two
different uplinks: 145.85 for APRS software and messages.
145.93 for all Mic-E, D7 and D700 radios.
That's more than one pass per hour on 145.825. Lots of contact
potential from your mobile...
For APRS birds:
http://www.ew.usna.edu/~bruninga/pcsat.htmlhttp://www.ew.usna.edu/~bruninga/iss-faq.htmlhttp://www.ew.usna.edu/~bruninga/ande-ops.htmlhttp://www.ew.usna.edu/~bruninga/GO32-ops.html
For AMSAT birds:
http://www.amsat.org/amsat-new/satellites/status.php
For many of these satellites, you don't even need a tracking
program. Just a slip of paper on the dashboard... See:
http://www.ew.usna.edu/~bruninga/MobileLEOtracking.html
The best antenna is a 19.5" whip in the center of your roof. 5
dBi gain on the 2m uplink and almost 8 dBi gain for the very
weak UHF downlink (above 25 degrees)...
Watch for special event info.
WB4APR, Bob
Hi folks,
someone I was in contact with recently gave me an url to visit.
REMOTE RADIO
http://www.remotehams.com/http://www.remotehams.com/Online-Radios
The site is in England, and has several radios online that you can adjust
the tuning on.
I went and had a look and a play. Then had an idea to try out.
I tuned into a NOAA wxsat on the 137 MHz band when my sat tracker said it
was over England.
I then started the WxSat program that turns the telemetry into images.
I had to tick a different box on the sound cards recording settings, and
then it happened.
For the first time, I was receiving an image of Europe from a VHF NOAA sat,
via the online radio.
Thanks to the folks that made this site possible, I love it.

Hello
To play the devils advocate for a moment.
With a geo (stuck) sattelite we are pretty much stuck with the same foot print forever. Unless of course there is some sort of cross linking in the future. I very fondly recall AO-40 and bringing it up on my computer and seeing where the foot print was today. Maybe it's the Europeans or perhaps the VK's, ZL's (love their accent), or maybe some JA's, (practice my Japanese). At some time, I knew I could cover the whole planet. I do of course believe this is an excellent opportunity, though there are a some limitations.

Can someone explain this "new" thing about the difficulty in
compensating for doppler?
I used to do it with one hand on a knob, or with one of the many
programs available.
Has something changed??

Disagree: I learn....
Pulling for P3E...
Say it isn't so.
Say it's just a dream....
Just this past weekend, I was reading an OLD QST from 1974 that had
mentioned the notion that AMSAT wanted a geo-synch satellite by 1975. How
amazing. The thought was kicked around on a local AMSAT 2-meter net in the
early 1990 (back during the Mode K days of yore).
Imagine...ULTRA RELIABLE DX...24 hours per day. Those with antenna
restrictions or home-owner's covenants could be QRV. And if the up/down
links were UHF and above, a pair of helices could be used INSIDE, pointing
through a window....
Just a thought, though. What about our European and Asian friends? Could
facilities be included so that geo-synchs over their respective footprints
could be linked? Or possibly the satellite being "parked" over an area that
could include the US and Europe? I realize that it is all dependent on the
space that the host bird has.
This is truly exciting!

I confirmed that gsc.exe could not work on Windows Vista.
We can setup seemingly WiSP on Vista, but gsc.exe can not
run with a error message. I guess that the correct setup
information are not written into Registry.

And the store is back! Thanks Paul and Martha.

I just got off the phone with our domain name provider (on hold for 52 minutes). It WAS suppose to renew automatically. They have no idea why it didn't. It should be restored soon.
