? Higher FEC would make it harder for you to lock a signal, because not as many errors would be corrected.
However I have a theory too.
My theory is that it would be the narrow bandwidth channels that they'd receive, ie the low SR signals. (m guessing this even though it's contrary to my experience. Ie I've generally had an easier time locking wide transponders, but I think that's because of my drifting lnbfs.
Reason I'm guessing this, is because I've looked at a couple sats that had wide and narrow signals side by side with about the same actual signal strength. THe wide signal had just average quality and yet the narrow signal gave near perfect quality. Ie it seems to be possible to pull a narrow signal out of the noise. This is somewhat analogous to amateur radio, where to receive weak signals, you typically use narrow bandwidth, however the ham analogy is also a case where the bandwidth of the receiver is narrow too, thus filtering out noise outside the bandwidth of the signal, however it is my assumption that consumer FTA receivers don't change the bandwidth filtering of the receiver to receive narrow signals, which would allow lots of noise in. However I'm thinking that it's that there will be less interferrence from the noise with a low SR signal, whereas a high SR signal will experience interferrence from a wider spectrum.
Anyway, I'd be interested in what the SR values were for the signals received by the small dishes.
