I notice back then I also pulled the coax on my Tivos and reported the numbers.....although see numbers are a little off because I had an old setup.
Would be curious to see others if they have a SNR when the cable is pulled. Again....I'm not having issues so not sure what the difference is.
That's not the one I was thinking of. I also wouldn't consider a one-off report from one person to be reliable enough to base an opinion on that I'd repeat.
Until I spot what else I've seen again, or somebody else finds it, I'm kind of dead-in-the-water on any meaning of the "disconnected cable test".
I swear there was a thread where the test resulted in a few people getting RMAs. I'd be hesitant to RMA one of my own, unless I was certain it needed to be replaced. I'm not feeling to confident that this "test" proves much.
I'll still report back when I get a chance to try it on my 3 base Roamios. I'll be doing:
1. Base reading, for each tuner.
2. Pulled coax cable readings.
3. Readings with terminator on input.
4. Readings after a reboot.
I'd add 5. Readings w/o cablecard inserted. But, they are hard to get to on base models.
