Yesterday morning (10:57 UTC) saw an ARISS School Contact with participants at Ecole Les Muriers, Saint-Maur-Des-Fossés, France.
This was a nice opportunity to listen in since the position of the
ground station at the school meant the UK could listen in to the
majority (if not all) of the downlink. Usually when it is further east
in Europe (Germany/Poland etc) you get the initial calling and the start
of the contact but the ISS goes out of range before the session ends.
So I set up my FUNCube Dongle PRO PLUS connected to the discone in the loft and the new SDR-Radio V2 Preview software. I had to start the recording remotely as I was in work, but have played back the IQ file and made a video showing the decoding.
As you can see/hear I appear to get the full contact and the questions were (source)
1. What is the temperature outside the ISS?
2. What does the Earth look like from the ISS?
3. What does the Moon look like from the ISS?
4. Have you already passed through an asteroid belt?
5. Are you able to go outside the station, into the space?
6. What is your speed? Can you feel it?
7. How do you sleep? Do you have the same sleep pattern than on the earth?
8. Do the crew members sleep one after the other, or do you sleep all at the same time?
9. How do you know if it is morning or night on board?
10.Do you do any sports and physical activities? Do you lose weight?
11. Do you shave every day? If so, how?
12. Do you see any space debris? Can you see evidence of pollution of the earth?
13. What are your hobbies on the ISS after a day of work?
14. Are you happy to come back home at the end of your mission?
15. What is your current mission?
16. Why did you choose to become an astronaut?
17. How do you cook food? What is a typical meal in the ISS?
I was lucky to receive it given the interference monster was back! It does manage to get in on the act a few times but thankfully doesn't stop the show completely.
Over the last few months I've been suffering from increasing interference on the VHF/UHF and HF bands. Some of which I know about, the router I have puts out quite a few spikes on VHF but something local to me is putting out huge amounts of QRM.
I know it isn't internally generated as it disappears when I remove the antenna. I have gone around and powered off all the potential culprits in the house and discovered a switch-mode power supply for an external USB hard drive was throwing out some HF noise as was a digital photo frame.
I've suffered with interference on and off since getting back into the hobby back in 2010 and appreciate it is something I have to live with but it is quite annoying at times. I suspect the interference might be one of those power-line networking devices, but if anyone has any idea I would welcome a comment!
