[GCARC] Still more pictures from space!

Wed Jan 1 23:40:32 EST 2025

That was perfect - a 90 degree elevation pass (DIRECTLY overhead - that rarely happens) and they sent three nice images, two of which we copied clearly and the third with just a little noise. Throughout this session we've copied all 12 images from SatNOGS with several more days to go. Hopefully some other members have also been successful.

Thanks Jon - hey!
11:11pm tonight, if they still transmitting, is great pass.
It won't be visible, but should be able to hear it on your radio.
Rises from SW 23:11 local, near straight overhead with no doppler shift at 23:13 L, gone in the NE by 23:17 L
145.800 MHz FM, PD120, MMSSTV
Good luck!

They're still coming in for the next few days with new images showing up every few days. So far we've copied 12 different images on the clubhouse SatNOGS station. See if you can copy them yourself with your radio, or you can view them from the SatNOGS website for the clubhouse station. The link below will take you to all of the SatNOGS downloads and you can click on the observation number (the green box) for ISS passes and then click on the Data tab to see the decoded images. If you want to test out your own ability to decode the signals you can click on the Audio tab that will download and play the SSTV audio tones. This is one of the longest SSTV sessions that we've had so it's a good opportunity to check out this activity.

Pictures are still coming in from the ISS for the next week. The SatNOGS station at the clubhouse has received a few really good ones, as would be expected with a 22 element vagi aimed at the station, that can be viewed at the site shown below. High passes should be copyable using an HT with a phone SSTV decoder as described below. Give it a try.

Now the Russians are celebrating Christmas with more pictures from space!. They'll begin on Christmas day at 9:55 AM (on the next overhead pass following that time, of course) and end on January 5 at 9:20 AM. Instructions for finding the pass times and listening and decoding the signals are below. These signals are strong on high passes and can often be heard on an HT. Give it a try!

As usual thanks for John K2QA for the tip.

Yet another ‘Pictures from Space” session is going on now.

Below is the ARISS announcement:

https://ariss-sstv.blogspot.com/2024/11/nov-2024-sstv.html

Nov 2024 SSTV

With the new hardware and software installed and tested, here comes another SSTV event.

ARISS Slow Scan Television (SSTV) transmissions from the International Space Station are planned to start Monday, November 11 about 11:50 UTC and to end Monday, November 18 about 13:40 UTC. There will be some interruptions on Friday and Saturday to allow for the crew to conduct some school contacts. Downlink frequency will be 145.800 MHz FM. Images will be transmitted in SSTV mode PD-120.

The transmissions will consist of 12 imagers featuring activities from the 40th Anniversary celebrating amateur radio in human spaceflight.

Note that there is a new SSTV gallery site being used for this event at  https://ariss-usa.org/ARISS_SSTV/ . <https://ariss-usa.org/ARISS_SSTV/%20.>

Amateurs can receive the SSTV pictures directly from the space station by connecting the audio output of their two-meter transceiver via a simple interface to the soundcard on a Windows PC or an Apple iOS device. On Windows PC’s the free application MMSSTV can be used to decode the signal, on Apple iOS devices you can use the SSTV app for compatible modes. For Linux systems try QSSTV.

The ISS puts out a strong signal so even a 2M handheld with a 1/4 wave antenna will be enough to receive it but one’s chances of success are significantly improved with the use of a handheld beam antenna. The FM transmission uses 5 kHz deviation which is standard in much of the world. Many FM rigs can be switched been wide and narrow deviation FM filters. For best results you should select the filter for wider deviation FM. Handhelds all seem to have a single wide filter fitted as standard.

ISS passes can be predicted from the heavens-above.com<http://heavens-above.com/> website. Be sure to enter your latitude and longitude in the upper-right box to get the right pass times. Also be sure to click on “All” passes to get even those that aren’t visible to the eye.

Thanks for John K2QA for the tip and good luck.
