It's never been easier to get a ham licence, but IIRC, the lowest level does not allow satellite comms. Still worth getting your "ticket" for though.

Been a ham for 22 years and it's still the great hobby it always was.

David, consider doing it. You will enjoy it immensely.
The Yupi is a great rig, but imaging having one you can talk back on :)

My pilot friend brought along his transceiver, he is allowed to transmit, though not sure if he can to the ISS, maybe just to aircraft etc.
In fact he got a training captain to broadcast to me long distance from a 747 at a set time but despite trying to rig up an aerial I did not hear his broadcast.

I have thought of it, but maybe I will stick to listening at present and I don't have the knowledge or facilities for proper antennas.

Hi,
Packet signals heard quite frequently lately but this evening (Thurs) I heard strong voice comms (Russian) from around 21.29 to 21.34 BST on 145.800 FM freq. Quite a while since I last heard anything.
All the best

Hi Andy/all,

Not managed to catch a sight yet during this set of visual passes thanks to the weather :(
There will be contact with students in the USA in a few days time (April 19th).
It wll be a telebridge contact via Italy so might be worth a go.
They will start contacting the ISS around 18.03 BST and the pass will be between 18.06 to 18.11 BST around 20deg alt. (for my location).
Will give it a try, you never know :)
All the best

2012 April 19 18.09 to 18.13 1/2 BST plus or minus 1 minute as watch not synchronised.

Carrier signal break, then a few pings, then extremely faint voice, then very faint, faint voice, then moderate again moderate again moderate, then faint.
Possibly extremely faint after 18.13 1/2 UT?

'We lose about 100 metres a day due to drag'. American astronaut.
?? a boost every month ??

'We have 3 Russians, 1 Dutch, 2 Americans' ?including him?

'Natural Aid'? earlier.

So at least 3 messages heard clearly.

Yupi 7100 Watson 889.

Regards, David

Thunder just a little earlier.

Hi,

Heard voice comms from 18.10 to 18.13 BST.
Quite clear (U.S. astronaut Don Pettit). Heard reply to three of the questions very clearly and then started breaking up shortly after the astronaut reported having problems hearing a response from the students.

All the best

Hi,
There will be a chance to catch some more voice comms on Wednesday 2nd May when astronaut Don Pettit will be speaking with students in the US.
This will be a telebridged contact from Italy beginning at 17.14 BST. The pass for us will be around 17.14 to 17.21 BST.
All the best

2012 May 02 17.15 BST Pings beginning, heard maybe 4 or 5 pings over next minute. then faint voice. Repeated Call Sign many times. IK 1N??. 17.18 1/2 BST 'Switching to back up'. 'You can now ask questions'. 17.18 onwards clear strong fully understandable answers.
We make oxygen from water giving oxygen and hydrogen.
We did combustion experiments with interesting results. Burning things?
We use accelerometers and GPS for position? (I am surprised they use GPS system DF). Carried on getting fainter till 17.21. Last heard 17.21 1/2 BST.
These times are plus/minus 1 minute as I did not synchronise watch.

So could hear clear strong comms.
Cloudy overcast now and maybe all day.

Regards, David

Hi,
Well done on getting something David, I didn't have as much luck as you. Got first signal at 17.16:45s BST and last one at 17.19:30s BST. Not very clear and all I heard was (from the astronaut), "...can't copy that question over" and the callsigns .."IK1SLD ... IK1SLD ... NA1SS" then several garbled requests before it faded. I think looking at the ground track on HA it wasn't too favourable for me being further north although I have heard better contacts on similar tracks in the past.
Better luck next time.
All the best

Nothing on the scanner, just a couple of screeches early on ... but did just get a gorgeous view of the ISS passing directly overhead (through the summer triangle) at 01:23BST, really bright.

Nice clear night (at last!). Was hunting in vain for Open Clusters M39 and M29, but either my bins or my eyes aren't good enough! ... Did get a nice view of the coathanger though.

Hi,
Just heard Russian cosmonaut Sergei Revin trying to make contact with amateur radio operators on the 21.21 BST pass (Sunday 17th June). Very clear and lasted around four mins.
It seems like the packet freq. is now no longer in use and they are using 437.550 instead. I haven't heard anything yet but keep listening out for it.

Thanks for the new frequency, Dave.

Might explain why I've not had much luck on the last few passes I've listened to, but then again - I've got a bit out of the habit of listening lately.

Have programmed the new freq into the scanner and will keep you posted.

I got a couple of blips on tonight's 23:37 BST pass, one of which was on the new frequency, but nothing I'd really say was a proper signal.
