Good Evening everyone....nice to take a break from politics, etc.
On tonight's AO-51 QRP pass at 2330z pass, I was using my ever-faithful Icom
2AT as an uplink. At 1 watt, I was pretty amazed at how good it sounded in
the downlink...and was able to work Drew, KO4MA, Dave, VP9/G1OCN in
Bermuda, and Paul, N2BX.
Tomorrow night's pass I'll be trying the low power setting: 100mW.

Hi Jeff,
I only set the mode to R36, everything worked fine.... also with 1900mhz...

I have an original VC-H1, never even opened it. I did not buy the cable to
hook it to my D7a, 700 or 710 (possible?) when available. Is there anywhere
to get the cables now? I want to try and copy ISS SSTV with it.

Hi All
I left my setup and downloaded 7 photos today. Only two were really clear.
The rest had a lot of noise in them. Hopefully I can keep it going like this
for the duration.

All,
?
It was quite an exciting day for ARISS yesterday with the Expedition 18 crew
docking and the start up of Richard Garriott's ham radio activities. Here are
some updates and plans for ARISS during Richard's flight.
?
Richard, W5KWQ, fired up the radio and started SSTV operations just a couple
of hours after docking. Prior to flight, Richard planned to support a slide
show mode using the SpaceCam software and the SSTV interface box at the
beginning of his flight. This is what you saw yesterday. Richard downlinked a
number of SSTV images using Martin 1, a higher quality but longer transmit
SSTV mode. The Russian team, led by Sergey Samburov, RV3DR, had requested
testing several high quality image modes during Richard's flight, so don't be
surprised if you see Martin 1 or other high resolution SSTV modes during
Richard's flight. We asked Richard to move to the default Robot 36 mode for
the time being and to space out the images once every 3 minutes to reduce the
radio transmit duty cycle. Richard confirmed that he will support this. He
also has transitioned to the VC-H1 as this will allow Richard to use the
computer to support his Earth ops and still support SSTV.
?
We have over 300 image uploads on the Gallery site by hams all around the
world! The ARISS team appreciates your volunteer support through all the SSTV
images that have been uploaded. A volunteer ARISS team is working 24/7 during
Richard's flight to review these images, to understand how the SSTV operations
is progressing, and to include some of these images on the Gallery pages. ALL
the images you have uploaded have been archived and are being reviewed. Please
continue to upload these images as they help the ARISS team analyze and
redirect the SSTV operations. You are welome to upload these through the
gallery page:
?
http://www.amsat.com/ARISS_SSTV/
?
We also have a blog available that provides the latest ARISS information for
this expedition. That blog is located at:
?
http://www.ariss-sstv.blogspot.com/
?
You can also reach these sites through the ARISS website:
?
http:/www.ariss.org
?
Some other information:
?
SSTV uplink/downlink: Richard is really not supporting SSTV uplinks during his
short duration mission. The downlink is on the normal ARISS VHF downlink,
145.80.
?
General Voice Contacts: Use the regular general voice frequencies. 145.80
downlink. Uplinks are 144.49 in Region 2 (Americas) and 145.20 for Region 1
(Europe, Africa, Middle East) and Region 3 (Australia, Asia). Richard and Mike
Fincke, KE5AIT, have been on the air on voice since shortly after docking
yesterday.
?
Sleep Period Activity: We have asked the crew to turn packet on during sleep
periods. Our intent is to keep SSTV active during their work day. The
rationale for this is that we are having some issues with the software based
(SpaceCam) SSTV system occasionally keeping the radio keyed down after an
image transmission. And we have a limited set of Russian batteries available
during Richard's flight for the VC-H1.
?
Additional SSTV Information: The computer-based SSTV can also support SSTV
picture taking using a USB camera. We don't anticipate Richard using this as
his primary SSTV operations for his mission will be with the VC-H1. The USB
camera was checked out over the weekend by the Expedition 17 crew, where they
took photos of themselves and downlinked these to the ham community.
?
You are witnessing and are a part of history: Some of you have asked why
Richard is using his callsign for some QSOs and SSTV contacts instead of the
ISS station callsigns. There is a long and proud history that is attached to
the Garriotts. This includes ham radio in space and their personal callsigns.
25 years ago, Richard's father, Owen Garriott, W5LFL, initiated the first ham
radio contacts from space on the STS-9 SAREX mission. Richard, W5KWQ, is
following in his father's footsteps, using the ARISS ham radio system
extensively on his first flight. And Richard's callsign is actually his
grandfather's original callsign. So you can see that this mission touches 3
generations of ham radio and 2 generations of ham radio in space!
?
JOTA: Remember that Jamboree on the Air is this Weekend! Scout groups are
welcome to call Richard or Mike Fincke over the weekend using the General
Voice Contact frequencies (see above).
?

scheduled as follows:

Mike,
If you don't have a software solution May I suggest MM-SSTV (Windows app)?
It is free and very simple to use, all you need is a soundcard interface
between the radio and your PC.

I record the pass and then set about decoding it later. The first
decode of the ISS image I captured was terribly skewed, but I was able
to adjust qsstv on subsequent attempts to get it bob on.

Hi Folks,
tried to catch ISS with my TH-D7 + Rubber Duck on Office's terrace in
JN33MO. The pass was very good, most of the time over 30deg. Just heard
voice traffic (one word fragment, guess wa Garriot ending a contact) at AOS,
then nothing.
Anyone was succesful with that equipment?

The gain of a stock rubber duck antenna is usually minus 12 to minus 9 dBd
gain. The average car 1/2 wave dipole is Zero dBd gain.
More gain, better results.

I had a thumping signal yesterday with my homebrew J-pole. Nothing
more. I thought I might have used the Yagi, but that would probably
have only been worthwhile for catching the very ends of the pass. As it
was, with my antenna about 12' off the ground in a suburban back garden
with trees and buildings around, I was getting full quieting at 15
degrees above the horizon!
http://www.gjcp.net/~gordonjcp/dualbandjpole.pdf
Here's a copy of WB6IQN's dual-band design (mirrored because I don't
want to cane the author's bandwidth). I built the single-band version,
and it tuned up perfectly at 144.9MHz when built as described - I've now
built three, one on a pole in my back garden, one that I gave to a
friend to listen to the local repeater with (along with an old Icom
IC-22A - must ask him if it's got a 145.8 crystal!) and one to stuff
into my laptop bag and take to work. You'd actually have to try to get
it wrong.
HTH,
Gordon

Thursday 10:45utc pass over Europe:
With the very latest keps I monitored both 145.800 and 143.625.
Late in the pass, a carrier appeared on 143.625.
Also I heared now and then voice from another source (distorted) through that.
Initially I believed this was a local station transmitting on 143.625.
But: switching between HOR/VER/LHCP/RHCP gave exactly the same
ratio of that carrier versus the voice/other signal... they must
have identical polarization: too much coincidence to me.
Then: the carrier faded down fast in the last 2 degrees elevation,
like the ISS 145.800 also always does: the carrier must have come
from ISS: I guess the D700 also has 143.625 programmed ?
Conclusion:
I suspect that maybe the Kenwood D700 onboard was transmitting
on 143.625 and at the same time the astronauts tried via the other
radio to reach Moscow (like they do every day). Most likely Moscow
also could not hear the 2nd radio, as the carrier was strongest.

Sounds like the Russian VHF comm. system which has a multi polarity
antenna array. They may have locked the PTT in anticipation of a ground
pass over Moscow and you were hearing background noise from within the
ISS.
