Dr.Dish:
It took a while, because from my location I can´t see TDRSS very much,
because of a lot of trees. With the Panasat 520 we discovered some problems.
There are two different versions on the market. I got one last years which
did fine on scpc-channels and others did not. Somebody must convert them in
the "real one".
But now back to your SSVC-question:
I just received a report from Wolfgang Walter (thanks Wolfgang!) concerning
SSVC via TDRSS. He receives a clear signal in Germany with his d-box.
Without using the difficult service-menu. There is no use to program the
unit to the LOF of 5.150 GHz. Just use 9.75 or 10 GHz and add the difference
between receiving frequency (4.040) and c-band LOF (5.150) which is 1110
MHz. This means you have to use the frequency 10.860 GHz (LOF 9.75) or
11.110 GHz (LOF 10.0). The symbol rate is 5998 and the FEC is 2/3. Wolfgang
did the whole job with a 150cm dish.
