Start at the dish & follow the signal path!<BR>
Verify your dish/LNB are good, and if so then proceed to investigate your card.<BR>
Either use a known-good freeview box to see if you get a signal or If you cant do that (or if the box fails to acquire a signal) then;<BR>
First, use a "cheapie" satellite squealer ($15 off TM) on your coax, set it to just start to make a noise then move your hand in front of the LNB - if there is not a LARGE increase in noise (reflected of your hand) from the squealer, then your LNB is kaput.<BR>
Second, Deflect the rim of the dish by 5mm or so (a gentle push with a fingertip) and you should note a drop of signal on the meter. do this for left/right and up/down deflections. (your LNB coax exit point should be roughly at the 8-O'clock position when viewed from the front of the dish) This step will prove if your dish is correctly aligned.<BR>
I would expect a relatively greater signal from Freeview transponder compared to the SBS transponder.<BR>
Thirdly, if the dish proves OK, use a command-line dvbtune -like command (sorry not too sure on the syntax off the top of my head) to verify the card responds correctly.<BR>
<BR>
Good luck!!<BR>

OK did some more testing. If I 'Watch TV' on the Satellite input, if
shows 71% signal strength with SBS (Vertical?) and 53% with Freeview
channels (Horizontal I think). But S/N of 4.5 dB in all cases. BE was
originally zero, but after playing with LNB settings to try and wake
something up, I am now getting BE of 3k-40k reported (after restoring
the LNB settings). If I remove the cable from the LNB to the DVB card,
signal strength drops to 0% but S/N stays at 4.4dB.
So, anyone want to guess if its the card or the LNB that's broken? I'm
tempted to get a new DVB-S2 card cause that's easiest, but its $100 that
I don't want to spend if the problem is the LNB...
