A little
more fun:
feedhunting
like a
professional
satellite
enthusiast
11. Feedhunting on SES6 (40.5W). First we used the SatSpectr software
to do a spectrum-based blind scan of all active transponders.
12. We used the SatSpectr in combination with a TBS 5925 tuner
and could determine the reception parameters for an interesting
transponder: 3658 L SR 1666 FEC 5/6. Notice the very low Symbol
Rate. The C1W-PLL is performing great with this DVB-S2 modulated
signal.
13. Further tests were performed, this time with the EBSpro
software (which uses the Streamreader DLL, too). One
particular transponder at 4086 MHz caught our attention: for a
C-Band transponder it features an unusually high FEC of 7/8 in
combination with a rather low symbol rate of 1476. The C1W-PLL
had no problem locking onto this transponder as can be seen in
the demodulated picture.
