A few minutes ago.
14.03 3/4 UT breaks in bad interference giving very quiet periods. Maybe beaks in carrier signal?
Then faint voice becoming very strong indeed American male voice.
'SP2 ZIA SP2 ZIA This is OR4 ISS Lot of interference'. Repeated message.
Do you want to go to back up chanel? repeated. o.k. GOING TO BACK UP CHANNEL.
When on back up chanel it got fainter for me.
Very strong at 14.06 1/2 faded away 14.07 1/2UT.
A few answers to questions but mainly talking about Interference and going to back up chanel.

So heard strongly but not very interesting.
Yupi 7100 Watson.

Happy New Year all.

Regards, David

Hi David,Tim,stella,Andy,
Was very disappointing, as you said David the interference being reported by the astronaut spoilt it. Very frustrating because the transmission from the ISS was very clear and only heard a short reply to a question before the problem started.
It's interesting to see the difference now in the passes beteen the ISS and ARISSat-1. On the 29th (Dec.) the difference was around 35mins (ISS trailing), yesterday it was only a minute or so (on the 16.34 UT pass I heard the ISS packet signal followed by a (poor) automated signal from ARISSat-1 about a minute later). Todays pass gives a difference of around 48mins with the ISS leading this time. Todays ARISSat-1 pass I just heard a short while ago (14.52) was just intermittent static.
Came across a bit more info here ..

Best wishes for the New Year

Listened to all ISS passes today (except 17:14 which I missed).

Two brief voice comms on the 14:02 pass on 145.800 quite clear, male American voice: "Yes, [interference] Do you copy? Over." "Yes, there is ... "

Short burst of packet signal on the 15:38 pass.

Nothing on the ARISSat-1 passes for me, sadly.

Happy New Year all, and here's to more ISS listening in 2012!! :D

Hi,
The path of the ISS pass for yesterdays transmission wasn't very good for us and after changing to back up channel the ISS was out of our range for us but here's what was heard by someone in France ...

Hi,
Very good voice comms on todays 12.05 UT pass (Mon 2nd).
Heard very clear answers to eight of the questions asked by Polish school children. One of the best contacts heard for quite a while.
Also ARISSat-1 is still transmitting (quite clearly today) 12.44 UT.
All the best

Thanks Dave,
I listened to that recording you highlighted.
It seems I made a mistake in listening or more probably transcribing.

The call sign was SP2 ZIE not SP2 ZIA as I posted above.

The voice signal was loud and clear so I should have got it right.

regards, David

Hi,
Just a pointer to another school contact coming up in a few days time.
There will be a contact with a school in France on the 9th Jan (Mon) starting at 10.14 UT. The pass for us will be 10.20 to 10.26 UT. Well worth a try I think (very similar groundtrack to the last school contact which was very good).

All the questions being asked can be found in the usual place here.

All the best
Dave

Hi,

Was wondering if anyone had any luck with this mornings school contact ?
Heard very clear voice comms (10.20 to 10.26 UT), U.S. astronaut Dan Burbank was speaking to high school students in France.
Heard answers to several interesting questions regarding observing the stars from space, water recycling, the Alpha Magnetic Spectometer experiment, and EVA experiences.
Heard nothing on the following two passes.
All the best

Hi,
Just a reminder that there will be a school contact tomorrow morning 18th Jan, (only problem is I don't think it will be in English :( )
Dutch ESA astronaut Andres Kuiper will be speaking to students at a school in Belgium from about 09.47 UT. The pass will be from around 09,51 to 09.57 UT, Should be another good clear one even if it's only to check the strength of the signal and equipment.
Been many packet signals as usual with the odd Russian comm (143.625 FM) being transmitted at the same time as the packet signal.
All the best

All the best

A few minutes ago.
09.52 1/2 UT possibly faint pings. 09.53 some activity 09.54 voice but not very strong. 09.55 Man speaking Dutch I think rather than Flemish.
I visited many flemish carpet factories although a long time ago.
My contact was a flemish speaking Belgian who flew Hurricanes for Britain in WW2 so I heard him speak quite a lot.
09.56 Very strong speaking possibly to Karin?
I understood quite a lot of words but could not really get the gist. He was speaking about atmosphere, scopes etc.
moderate 09.57. Last heard 09.58 UT. All times maybe plus minus 1/2 minute.
145.800. Yupi/ Watson
Did not hear packet signals on 145.825 on separate Yupi standard telescopic.
Turned this off to concentrate on voice.

So heard well, but understood little.

Regards, David

Hi David,
I got first signal at 09.52.30s and lasted for almost 5 minutes. Quite audible but not quite as clear as the last two comms.
I have heard Russian voice comms recently (143.625) at the same time as a packet sgnal but I know they dont transmit on the 145.800 freq. at the same time as packet.
Glad you managed to pick out the odd word on this one (I couldn't understand any of it :( )
There is a translation of the questions here ..

1. In what way do you sleep in space?
2. What are the requirements to become an astronaut?
3. How is it to see earth from above?
4. Is there internet in the ISS?
5. How long does it take to fly from earth to the ISS?
6. What do you do in space in your free time?
7. What happens to the human body staying in the free space without any personal protection or cabin?
8. How is the ISS provided with oxygen?
9. Which daily tasks has an astronaut to perform?
10. What happens when an astronaut gets seriously ill in the ISS?
11. Imagine that the communication link with earth collapses for a longer period, how would this problem be solved?
12. Is it possible, in case of emergency, to operate on an astronaut in the ISS?
13. How is the weight core of the ISS determined?
14. How does a rocket catch up with the ISS?
15. How is your weight measured in the ISS?
16. Have you got a feeling of speed inside the ISS?
17. What happens with the packaging garbage in the ISS?
18. Does the launching of the rocket cause a sensation of pain?
19. How cold is it in space?

All the best
Dave

Apparently Dutch and Flemish are very close, but to an Afrikaans speaker Flemish is easier to understand than Dutch.
So there are differences.
But I would think the Dutch astronaut and Flemish school contacts had no trouble understanding each other.

Anyway it was nice to hear the voice from the ISS.

Thanks for the list of topics Dave.

Regards, David

Hi,

Just had a good visual pass and voice comms from tonights (Thurs) pass at 20.00. Watched the ISS for about a minute before it faded but heard the voice comms (Russian, 143.625 FM) untill they too faded at 20.04.

Incidently there will be a school contact (Italy) on Feb 24th at 14.02 UT. Not heard any for a while. It will be a low pass but well worth a try I think.
CalSky give the pass time as 14.02 to 14.09 UT (for my location).

All the best
