Hi!

One more thing concerning the TT 3200-S2 card:
I use the card with VDR and the plugin femon for reading the signal 
strength and so on.
Is there something to adapt in femon (and also szap2) to get correct 
readings or is there a driver-issue?

The only thing I've found about this is a post on the vdr-portal (post 
is in english):
http://www.vdr-portal.de/board/thread.php?postid=655267#post655267

If I tune to a DVB-s channel with my FF-card using szap2 I get something 
like that:
status 1f | signal 9c9c | snr cfcf | ber 00000004 | unc 00000000 | 
FE_HAS_LOCK

Doing the same with the DVB-s2-card i get:
status 1e | signal 0164 | snr 0077 | ber 00000000 | unc fffffffe | 
FE_HAS_LOCK
For a DVB-s2 channel something similar like:
status 1a | signal 05aa | snr 0031 | ber 00000000 | unc fffffffe | 
FE_HAS_LOCK

I've looked into the sources of femon and for the signal-strength in 
percent the value is divided by 655 (don't know where this is coming 
from). But the values for the dvb-s2-card are already very small  but to 
high to be in percent already.

The valu for ber is 0 (which is good if true) and unc seems to be 
allways -2 though this should be an unsigned value.

Am I missing something here?

Bye,
Andreas Brugger
