Is there a tutorial that you recommend I follow? Just feel a little lost as I see that there are a couple available for EUMETCast but not sure if I'm in the right direction.

Cheers @crazycat for the suggestion. MRTG will definitely come in handy for monitoring.

Can the MPE filter in BDADataEx be used to re-route TS traffic, or is it specifically for only MPE traffic?

I was able to pair up an instance each of BDADataEx and SignalEx to print some statistics, but still noticing some strange values here and it seems to occur regardless whether there is reception or not. Is it known if this is normal behaviour?
When specifying a parameter (e.g. "SNR") with SignalEx, a group of 4 values is returned. Are these the 4 consecutive samples of the selected demod in BDADataEx, a sample each from 4 of the 8 demods, or something else?

Look like hw failure - no i2c answer from stid135 chip and finally driver crash (IRQ handler and etc). Maybe stid135 overheating ? Maybe need increase Signal update interval in BDADataEx on Setup tab (default 1 sec)

Yes, I thought about that too. I've mounted a separate PC fan to cool it down within the case but could only get the chip temperature reading down to about 45°C; might have to extend the card out of the case and cool it externally.
