Hello All,
Just heard AnuSat go over - loud carrier on 137.400MHz but no modulation
detected. Using keps for space track object 34808.

Hi all,
Well, I finally did it. I let the smoke out of my Icom AG-35 preamp!
I've read several such messages on the list over the years. Glad to know I'm
not alone in this club.. hi hi
Before I replace the 3SK121 with an identical unit, I wonder if anyone has
used a similar FET with better NF? The AG-35 specs I found stated 1.5 dB NF
and 15 dB gain.
I went through my collection of new parts and found a few Agilent ATF 54143
hemt..
The NF on similar designs is more like .38 to .5 dB and gain is 19-22 dB.
I wonder if anyone else has had the wild idea of rebuilding their preamp?
I'd like to retain the enclosure and relays, etc.
Several 54143 designs are available, such as this one:
http://www.qsl.net/yu1aw/atf54143eng.htm
Thanks for any help or ideas.
73,

Trevor,
To answer your question ...
I followed the third link from the Southgate Amateur Radio Club bulletin
regarding ANUSAT and the quote to which you refer..
The complete text follows ...
(According to the story, the quote is by the Vice Chancellor of the Anne
University ... which is why I found it worthy of note).
ANUSAT being an acronym for ANne University Satellite
While not SPECIFICALLY stating exam results would be tramsmitted by
this satellite Dr P. M. Jawahar's remarks are quoted in the same ontext
and paragraph as the the rest of the information regarding the Anusat
satellite, which, according the Amsat India website is an 'AMATEUR' satellite.
12 years ago we were warned by Vommander John Brannegan that we would lose
the amateur satellite bands to the universities.
It looks like Winston Churchill was on the ball as well ... this is not the
end, it's not even the beginning of the end - but perhaps it's the end of the
beginning.
(With apologies to Winnie The Poo).

India Launches University-built Satellite
By P. Vijian
NEW DELHI, April 20 (Bernama) -- India successfully placed two
satellites in the sky early today, one of which was designed and built
by Anna University in Chennai -- the first satellite built by an Indian
university.
The Polar Satellite Launch Vehicle (PSLV-C-12) soared into the sky
at 6.45am (9.15am in Malaysia) from the Sriharikota spaceport in Andra
Pradesh, in south India, lifting the two satellites, RISAT-2 and ANUSAT
-- an abbreviation for Anna University Satellite.
"The indigenous ANUSAT was designed, built and fabricated by 10
faculty members from Anna University. It took us nearly eight years to
complete.
"This micro satellite will help in storing and forwarding data. It
will help us send confidential data, like examination papers. This is a
proud moment for India and the university," Anna University
vice-chancellor Dr P. Mannar Jawahar told Bernama.
The India Space Research Organisation (ISRO) funded the ANUSAT
communication satellite, weighing 40kg and costing nearly RM5 million.
It has a life span of two years.
The Israel-designed RISAT-2 or Radar Imaging Satellite, weighing
300kg, with all-weather capability to take images of the earth, would
enhance ISRO's disaster management ability.
"RISAT will help us in monitoring natural disasters like floods
and cyclones. It has a life span of three years. ANUSAT is the first
experimental communication satellite built by an Indian university
under the guidance of ISRO," ISRO spokesperson S. Sathis told Bernama.
Last October, ISRO launched the Chandrayaan-1 spacecraft that is now
exploring the moon from lunar orbit.

I am not aware that anyone at the University has said that confidential data
would be passed by the satellite on an Amateur frequency. Do you have any
University references for that quote?
My understanding was that this was a technology demonstrator for a store and
forward system.
While you could in theory build a dedicated satellite for handling exam papers
you have to ask why bother since you could use any number of far cheaper
alternative systems.
It sounds to me like the type of paper justication you might make to get funds
for a demonstrator project. Bear in mind that the mass media can distort
things that they don't understand.
One of the students, Sidharth Balasubramanian, who was involved in the
development of the ANUSAT communications system has some information on his
website. No specific freqs quoted except for the 149.522 MHz command receiver,

I assumed ANUSAT to be an 'amateur satellite.
Perhaps I presumed too much.

Hi All,
Q1: I have been thinking about getting a TS-2000X but I would appreciate
any input regarding the performance of the 1.2 ghz module. I seem to recall
that Kenwood had a problem with the earlier UT-20 modules but I don't
remember if that was due to poor receiver performance. I would be hard
pressed to find a transverter for $450 which is the current delta between
the TS-2000 and TS-2000X. But, if the UT-20 can't hear then that's tossing
the $450 down the crapper. (I am aware of the 436 birdie....)
Q2: I see $300 discounts on the TS-2000X from several sources. That could
be due to either the poor economy or Kenwood clearing the inventory for the
TS-2000 replacement - any rumors about the replacement?
tnx & 73,
WA7NE

The coax shield coming off the antenna boom at a right angle looks
like another parasitic element being added to the antenna causing
severe distortion of the antenna pattern. But if one installs the
antenna in the X configuration and attach the cross boom in a
location away from any of the elements one can tightly run the coax
across the metallic cross boom with little effect. This was tested
by WA5VJB and is a published article.
I have my M2 436CP42UG mounted in this fashion and it preforms well.
73, Ed - KL7UW
maybe someone else can point to the link to that article.

Hi Wayne,
For satellite work, 1.2 ghz receive performance is irrelevant. It's always an
uplink. I have yet to hear anything on 1.2 ghz, other than a beacon off to
the west. The only repeater within earshot went off the air a few years ago.
But L/US is a great mode on AO-51.

Hi all.
would like to use IT on an old latop PC P3 500 under Windows 98
for my portable equipment, IT turns very well in MSDOS mode or
under Windows, but I have a problem with my tracking system
"ARS RCI-SE" from EA4TX on lpt1.
In my bat point i launch in first RotorDRV then the compatible driver
for my card RCIKCT and in the last OrbitDRV just before launching IT,
all it lance well, but once IT launched when I call the traking by the ?R?
cmd all it stop and everything is still blocked.
If you have an idea of the problem, or better a solution thanks for doing
me to know it.
Thanks in advance for your answer, regards
--
Jean-Yves F5LHW.

i also monitor the frequency on the 48 and 49 pass of the satellite very
strong carrier,
those keps are?on the money, scanned the uhf but did not hear a downlink,
from the information there is suppost to be a vhf up link and a uhf downlink
with store and forward ??

Hi All,
The 137 signal might?be coming from the other payload or even the launch
adaptor bit perhaps? There are two objects close together and a third one that
is behind and above...keep tracking
cheers
Graham

The first thing that occurred to me was that if people like Mark
Shuttleworth and Richard Garriot have got $20-odd million to throw
around on space tourism, then perhaps they might be amenable to making a
hefty donation to amateur satellite launches.
I can see packet cubesats being a great help with communications for
things like the OLPC project.
Furthermore, the cost of launching is (for the moment) only going to go
down - can we get a discount for buying a batch of launches? Has anyone
priced up getting flights from the Iranians?

Could be this band will gain some revival with DSTAR we have one here in
Montreal on DSTAR with high speed internet link. Some folks (read
one) are transmitting audio and video in data mode we even can see them over
the internet.
Just gp on http://raqi.ca/braq/live.htm and click on "WEB CAM LIVE DE MARIO
SI DISPONIBLE" It is a balloon launcher group.

I fried my UHF one too...I order a couple from ICOM. With my very limited
electronics building skills i cut the dead one leaving as much
legs as possible and i resolder the replacement over the cut legs. Not elegant
but quick and effective. Is this is achieving the same
overall previous gain figures? that i don't know but it works.
I have another one to replace in a different type of preamp but the FET is
below a lot of other components and he's flat mounted (No legs)
i don't come up with a solution with this one?
