Joe. very little of ISS is cutting edge in its technology. somewhere at
NASA's web sites you can find which state things were made in...the solar
arrays are home grown. That of course does not mean that the US is the only
country that makes them.

Ultimately it's all down to politics in Washington DC.
If you think about it if the US cannot afford to sustain a small space station
that's as close to the Earth as possible then there is no way they can afford
a base on the Moon let alone Mars. ISS requires frequent resupply missions to
keep it going, it's nowhere near self sustained. They haven't even got the
dirty laundry issue cracked - how do you wash clothes in space ?
Personally I think ISS will still be there in 2025 and even then they'll be
looking to extend its mission.

Hello AO-51 V/S gang!
I've been on the past couple of nights trying out my modified K5GNA BBQ
dish, I had removed the dipole and replaced it with a LHCP patch feed I
built. Past mode */S runs on AO-51 were spent getting the feed back in
the focus. The passes this week though still left me with some bad
fades and signals varying from S9+ to nothing but noise.
Well I finally figured it out during the 00:00 pass tonight... I'm using
SATPC32 rotor control and I was fiddling with the pointing corrections.
Tonight was an overhead pass, so the signals should have been great.
They weren't though, so I started tweaking the rotor degree
corrections. Came to find that a +14 degree azimuth gave me the great
signals I expected to hear! So I got to thinking about it.
I know the rotator/antenna assembly is pointed right, north is north and
east is east and such. All of the other antennas give me the kind of
signals I expect, when pointing toward a particular satellite and some
local beacons and sweeping around them. So it must be one of two
things: either the patch feed is off center, and I'll admit that it was
heck to line up exactly using the PVC arrangement that I have created to
get the AIDC downconverter pointed back toward the dish. I looks pretty
centered... but, could it be off just a tad to the side so that I am
actually feeding off-center, hence the need for a 15 degree adjustment
to get the best signal? The other thought, the dish is mounted with the
left edge about 1 foot to the right of the 70cm 40el crossed yagi,
could the yagi be influencing the signal causing the apparent bend in
the pointing? And probably vice versa, if so.
Your thoughts on this would be appreciated. Meantime, I have at least a
workaround to get the solid downlink that I was looking for. No
polarization fades with the CP patch, and the 15 degrees offpoint isn't
going to affect the 2m uplink as the bandwidth of that antenna (20el
crossed) doesn't seem to mind. So, hopefully you won't have to hear me
sign because I lost the downlink anymore this week!
73 and thanks,
Jerry

First of all, thanks for all the replies.
Where I got that info was off the ISS FAN CLUB site
And was from some one that seemed to be knowledgeable..
But must have been opinion as well ..
Trust me when I say that I hope it is around MUCH MUCH
Longer .. I would like to be able to work thru It long into
My retirement which is in 5 ish years.. And aee them do some
Other amateur radio projects, like a constant running SSTV system.
More then one radio .. Things like that .. :)
Again, thanks for everyone's thoughts ..
Always welcomed and muchly appreciated

It is with great sadness that I learned of the recent passing of Art
Goldman, N3OY (formerly WA3CVG). Art was 67 and succumbed to melanoma.
Information is at
http://www.baltimoresun.com/news/obituaries/bal-
md.ob.ci.goldman05aug05,0,7067848.story.
Art was very active in CARA (Columbia Amateur Radio Association) and was
an AMSAT Life Member. Art often handled the satellite Field Day effort
at W3AO(see http://www.arrl.org/contests/soapbox/?con_id=133&call=W3AO
<http://www.arrl.org/contests/soapbox/?con_id=133&call=W3AO> for 2006
pictures. W3AO is the 19 xmtr multi-multi joint effort of CARA & PVRC).
Art lived in Columbia which has severe antenna limits. Despite this, he
managed to get on AO-40 using BBQ dish antennas. He show up frequently
in the AMSAT-BB archives. Art was also very active in the packet radio
world in the 80's & 90's. Art (with NG6Q) developed the TCP/IP driver
for the Eagle Computer card (Zilog 8530) for KA9Q's NOS. .
A personal remembrance: Rick Hambly (W2GPS), Bob McGwier (N4HY)& I
remember fondly the 8-hour x 2-way "captive audience" trip to/from
Dayton a few years ago. Despite Art's New York Jewish roots, he knew
every country & western song every made. What with McGwier hailing from
redneck Alabama, the trip was hilarious. I particularly remember the two
singing to Toby Keith's hit C&W song "I ain't as good as I once was, but
I'm as good once as I ever was!" (complete lyrics are at
http://www.cowboylyrics.com/lyrics/keith-toby/as-good-as-i-once-was-

I have been trying to get Instant Track 150 to control my IC910 when tracking
AO-51 VS. Since my down converter translates to 145 Mhz, I assign the down
path to the 2 meter side of the 910. I then create a factious path for the
432 side. When I enter the R command, IT starts displaying both the 144 and
432 sides but in alternating places.
Is it possible to tell Instant Track to concentrate solely on the 144 path and
ignore the 432 path? I have not found a way to do this and a search of the
documentation does not find a solution. What I was trying to do was let
Instant track handle the 2401 Doppler shift and I would handle a separate
radio for the 144 uplink.
Can I do what I want to do with IT or is it time to say goodbye to a friend
and move up.

Lost in this conversation is the fact that very soon we (US) will no
longer have a way to get to the ISS -- with the retirement of the
shuttle fleet... I have no hard data on the structural integrity of a
thin steel body that alternates between extreme heat and cold
multiples times each day for decades, but it seems highly improbable
that the ISS would remain on orbit for so many years and remain a safe
place for humans to hang out.
Don't forget that on orbit construction began in 1998 -- meaning the
primary structure is older than my car and I drive a seriously tired
old clunker! :-)

in the boom tube. Did anyone recollect if KLM ever missed pre drilled hole in
their workmanship? My assembly was on the side of a bit hurry
and i will have to recheck al the measurements but with the pre drilled bolt

Hi Folks,
I would be interested to know if anyone is using an ICOM 910 with the L-Band
module for Ao-51 uplink on the BBS? (The optional L-Band unit for the 910 runs
10
watts according to the book).
I am particularly interested to know what type/gain of antenna I would need
to get
a reliable up link. I am planning to use about 20 metres of Ecoflex 10, which
will
introduce a loss of something like 3 Dbs.
I know that the LBand/Digital up link is currently off, just gettting ready
for
the next 'on' period!

Hi Jerry, N0JY
The only way to eliminate all of your uncertainty is to point the dish to
the Sun and try to receive the Sun-Noise.
If the pick of Sun-Noise match both with the traking program of the
Sun and the indication of the AZ and EL of your control box then you
are calibrated otherwise you must apply the necessary corrections.

Hi Jim,
I use the same setup - but for analog uplink.
Antennas are two 19 turn helix stacked about 2 wavelength above
one another. The combined gain is 18 dBiC.
That works most of the time - but EIRP is a bit low when AO-51 is at
3000 km range.
For the digital uplink I think you need more EIRP.
Either add a PA with 30 to 50 W out or larger antenna(s).

Hi Gene,
Assign the IC-910 as a receiver using the
rx command (instead of as a xcvr) in the
satellite configuration record in the
itune.cfg file.
Something like this:
satellite AO-51 V/S ; mode V/S
downlink 2401.200 fm
uplink 145.920 fm
rxconverter 2256 ; for 145 MHz (tweek as needed)
rx ic910 1 60 ; on com 1, hex address 60
tx Radio2 etc ; fill in whatever the other radio is
This will use only the IC-910 receiver on just
2 meters. The other radio will be used only
on 145 MHz as a transmitter. You can share the
same com port if they are both ICOM radios.
Operation with separate RX and TX is in the
documentation on page 13 "Configuring Radios".

I use the 910 with one of the KJ6KO 60 watt amps to 50ft of lmr400uf, and a
m2 35 element yagi. Circular would be better, but I also use the antenna
system for terrestrial SSB work. Fine tuning the uplink is very important on
L band. Due probably to radio inaccuracies, and maybe on the spacecraft, I
have to offset the uplink by about 3 khz.

Hello to all,
I published a video/audio on the Internet with a few QSOs among of friends via
AO-7 - in the same orbit. I found interesting post the video file because I
still had not heard at other times this number of friends by using the AO-7. I
feel privileged to be in my city and listen to many friends through the AO-7.
I gave the name the video "A memorable night in the AO-7". Well, I am not an
expert in assembling the videos, but I hope we all enjoy and feel excited to
participate actively in future projects of satellites for radio amateurs.
The video is approximately 22 minutes,
see here: http://spacesat.blogspot.com/2009/08/uma-noite-memoravel-no-ao-
