Subject: [linux-dvb] Problems with low symbol rates

Hi All,
 
 
I tryied lately to read transponders which have low symbol rates (i.e. less than 12000) using a Hauppaugue DVB-S Nova card. I couldn't. I think have no installation issues or antenna issues, because other transponders work perfectly.
 
Should I blame the card for that? And in this case, what exactly on the card is creating this problem (if it is a problem)? Were the cards specially designed not to support lower symbol rates??
 

All the best,
Aurelian
 
Hi
From my own experience using a WINTV DVBS from HAUPPAUGE the frequency tuning is
more critical for SCPC transponders.Try to adjust it in 100Khz steps especially
if outdoor temperature is very cold or very hot because the local oscillator of
your LNB may drift or be slightly wrong.
In fact rather than changing the individual transponder frequency it may be better
to change the used LO parameter for the LNB.
Hope that helps.
Laurent
