Hi all,

after reading the posts about AO-16 apparently going silent, I checked 
the data from the Delfi-C3 backup groundstation, which has been set up 
at Eindhoven University in the south of the Netherlands by Jeroen 
Vreeken, PE1RXQ, he did a great job automating the station using his own 
developed software. As a test, he let the station track AO-16 
continuously for a couple of months since the beginning of this year, 
and a quick examination shows that telemetry stopped around the 22nd of 
May.  (We both have not been able to manually track AO-16 and listen for 
a signal in order to make sure it's not a problem in the groundstation 
which could be since the rotor does not work 100%, but reading the other 
reports about AO-16 on the BB it seems that it has indeed stopped 
On the following page you can find the telemetry files from the station 
at Eindhoven:


note that of all passes, flac (audio) files are available, as well as 
raw kiss files (.kss) and ascii files (.asc)
We used AO-16 extensively as a nice test signal generator since it 
produces AX.25 1200 bit/s BPSK just like Delfi-C3 will do soon hopefully:)
Hope the command ops can get this bird working again!

By the way, we are working hard to complete Delfi-C3 for her launch, and 
are learning a lot from integration of the spacecraft!
