Your RS graph looks just like it should, so it's not an issue at all.
When you say "noise", do you mean audible noise, like a crackly phone line?
Your Interleaving depth of 2250 or so does look rather high, suggesting a generally "noisy" connection anyway.
The large & sudden gap in the RSCorr graph is interesting.
Do you have any suggestions as to what may have caused it?
