Our good old friend UoSAT-2 OSCAR-11 is still (again) transmitting 1200 baud AFSK telemetry...
UO-11 was launched on 1st March 1984 !!!

Hello Peter,
I'm glad to see old friends in space ...
Perhaps it is useful to spend a few words on these two brothers in orbit.
At the time there was no Internet, the Packet was not yet born and the only way to have fresh Keplerian elements, newsletters, first-hand news was to receive these two satellites that had no transponder on board but only a space-earth link .
At the time, we adapted to anything. No SoundModem to use. Only fantasy and welder. In this article written for the Amsat Italia bulletin I described how to use a telephone modem to receive the UoSat-1 & UoSat-2 satellites. It is written in Italian but the patterns are universal.
As I know UO-11 is sending his telemetry 10 days with a pause of 10 days and this cycle begins again.
Edit: The TLM values may be faulty today.
Memories:
Richard, G3RWL, loaded the news up to UO-11
Here are all the UoSAT-1 bulletins starting with issue #10 until #109 when I stopped printing them.
I did not had a printer before #10
Thanks to Matthias DD1US for hosting my scans:
UoSAT-1 bulletins #010 - #040 received by DB2OS
UoSAT-1 bulletins #041 - #064 received by DB2OS
UoSAT-1 bulletins #065 - #079 received by DB2OS
UoSAT-1 bulletins #080 - #100 received by DB2OS
UoSAT-1 bulletins #100 - #109 received by DB2OS
I agree with Lucio, it was a great time when we had to send receiving reports by postal mail to Martin Sweeting and his team to the University of Surrey in Guildford.
There was a big community eagerly waiting for a new UoSAT bulletin to be downloaded every weekend.
Internet was not existing at that time, so it was a fantastic resource of latest information from the AMSAT and hamradio community world wide -, see yourself above.
It's a pity that 39 years later many LEO's even don't give a glimpse of that..
UoSAT-1 OSCAR-9 was launched in 1981.
UoSAT-2 OSCAR-11 launched in 1984 was carrying the first Digital Communications Experiment (DCE) which allowed Store&Forward communication based on simple asynchronous communication protocols.
I was very happy at that time to participate as one of very few UO-11 groundstations.
The DCE was the forerunner of the PACSAT satellites using AX.25 based PACSAT Broadcast Protocol (PBP).
I believe FalconSAT-3 launched in 2007 is the last OSCAR with a PACSAT BBS onboard.
As I know UO-11 is sending his telemetry 10 days with a pause of 10 days and this cycle begins again.
Yes, every 20 days UO-11 comes allive..
All the analog telemetry channels are gone, probably due to a failure of the ADC.

Clive Wallis, G3CWV passed away on 27th March 2015.
Be carefull, his "new web site" is pointing to a domain grabber with odd contents.
Hope someone archives his old pages berfore they are deleted...
