Possible ISS simplex operation
Greetings to kenneth and the group
After digesting all the exchanges about ISS simplex, I think kenneth has the right solution. Thanks for your civil exchanges and flexibility.
Can NASA coordinate with the ISS astronauts to monitor and use the Ericsson Ultra-HF radio equipment for simplex operation? It would be greatly appreciated.
Many amateurs have tracking programs and would know when to call.
The astronauts and cosmonauts could monitor the radio lightly squelched while they are awake.
I'm confident, if they heard people calling them, they would answer as they are available aside from normal resonsibilities.
As kenneth indicated, the frequency is 437.550 Mhz plus or minus about 10 Khz doppler. I've already set up 5 memories on my FT8800 with ascending and descending frequency splits and I have a good idea what memories to use at what time during the satellite pass.
If you guys could let the crew know we want to call them it would be appreciated!
Thanks kenneth!

FYI:
Current ISS setup.
Ericsson VHF is in FBG Module, Used for Schools and other stuff. We only have a 2-meter mono band antenna access in the FGB Module. This radio has the Speaker Disabled. It can only be used when wearing the David Clark Head sets. No speaker audio available at this time.
Ericcson UHF. Sitting in a locker some where on ISS
Kenwood D700 VHF/UHF, located the in Service Module, Active, used for SSTV , packet and other stuff. Connected to multi band antenna. Has working speaker and microphone. Located near the Dinner table. There are 3 Unused Multiband antenna port avaliable in Service Module.

Hello miles and thanks for the post. Do you know if one of the antenna ports will support Ultra-HF? As I recall, the antennas were installed in a prior spacewalk. I looked for equipment info on the amsat and RAC websites but could'nt find.
I'm all set and educated basically for SSTV, thanks. 73, pat

Antenna: Near as i recall.
FGB, Mono band, 2 co-phased antennas tuned for 147.xxx
Service module:
Antennas WA1, WA2, WA3 are all the same. Multiband 2 meter, 435-438, Patch wide band 1.2-2.4 ghz. Atenna WA4 is a 10 meter antenna ( do not have exact length) and patch 1.2 - 2.4 ghz. Each WA Antenna is mounted outside of the Service Module onto a Hand rail. The antennas are approx 90 degrees apart going around the hull of the SM. The Kenwood D700 antenna (WA1?) is mounted on the Earth facing side of the space station.
I guess i need to update my web page with better pictures of the mounted antennas. thanks.

Slow Scan TV on ISS update Saving Image format
By Miles Mann WF1F,
MAREX-MG News www.marexmg.org
Manned Amateur Radio Experiment
Hi everyone.
On July 30 ISS Expedition 13 Commander Pavel Vinogradov activated the SSTV project for few orbits from the International Space Station. Several more images were sent on the weekend of August 13/14. The testing proved that he had the entire basic configuration set up correctly.
Our thanks to the many stations that received and decode the test images. SSTV Images from ISS were received in many countries, including Russia, United Kingdom, Brazil, Australia and many more. Below is a link to one of the best images we received.
I have set up a new page to show many of the images we have received. To date, I have 7 unique images from ISS and many repeats. I you have new images; please forward that image to Marex at:
During the testing phase the ISS Slow Scan TV system may be intermittingly transmitting somewhere in the ITU approved 2-meter satellite band (144.000 146.000 MHz FM). After testing is completed the system will eventually be moved to a permanent frequency in the 2-meter ITU Satellite band.
Due to crew work loads and a recent space walk we are not sure when Pavel will have time for additional testing.
Over the next few weeks we maybe receiving images from the International Space station via Slow Scan TV (SSTV). The Marex team will be collecting these images from the amateur Radio and SWL community and we will post the best.
We would like to collect all images received. However in order to properly catalog the images we request you use the following image naming format.
After you receive you images, please rename the images using the following format, All Lower case letters. I have updated the naming format to shorten the file names.
Year 2006, Month 07, Day31, z, (UTC time), Call sign, Short text description, .JPG
Example
Old format: 20060731z1905wf1fwindowshot.jpg
New format: 0607311905wf1f.jpg
I removed the first two numbers of the year and the Z for UTC time. All dates are assumed to be in UTC dates. The images coming down from ISS will also have a time stamp embedded into the image. You can also use these numbers to generate you file names.
If we break this down Year =06 Month = 07 Day = 31 Time = 1905 UTC Call sign = wf1f Description (optional) = Windows shot Image format = jpg
Image Quality Please do not put a lot of text over lays on the images, Example, do not put web page or advertisements in the image. Your own call sign and date are acceptable.
Send all images directly to Marex at [email protected]
We would also like to know the following information in your email.
Name or Call sign Country / State Receiver Software decoding tool Elevation or range of ISS when you decoded the image.
Slide Show Mode: The Marex SpaceCam1 software contains a feature called Slide Show mode. It allows the crew to preload a directory full of images that will be automatically transmitted to Earth. The crew will not need to keep pushing a button to send images. In theory the system can run for weeks at a time without crew involvement.
The next phase of testing may use the frequency 145.800 MHz FM for the SSTV down link. The Slide Show mode will only be testing the Down link. The uplink frequency will not be published.
SpaceCam1: The SpaceCam project will be able to transmit over 200 SSTV images per day (Robot 36 format).
How to Decode SSTV from Space: http://www.marexmg.org/fileshtml/howtouseiss.html All SSTV transmissions will be in FM mode and will most likely be on the 2-meter band. This means that the Doppler frequency drift will not be much of a problem and you will be able to use your existing 2-meter station or a police scanner to hear and decode the signals from ISS.
If you have already have been successful in working the Packet station or talked to the ISS crew on 2-meter voice, than you already have most of what you need. Whats left is to connect your computer to the speaker of your radio and some SSTV decoding software, such as ChromaPix or similar software. http://www.barberdsp.com/
There are many choices in SSTV software, some Free, others with more features cost a few bucks. http://www.marexmg.org/fileshtml/sstvlinkpage.html
So have fun, find your best setup and start practicing how to decode SSTV on 2-meters.

Patrick, Your proposal is in line with the ARISS project plan already in works. This older paper (http://www.amsat.org/amsat/ariss/Papers/Phase%202%20AGM03Final.pdf) refers to the utilization and specifications of the hardware on board and planned enhancements at the time.
Discussions and coordination with the Russian representative are planned to have several components (like the Ericsson UHF radio) installed. Once this is accomplished, the balancing of experiments and operations can begin.

Thank you very much kenneth!
Please post its operation if and when it happens.
Thanks for putting up with this New Yawker!
