Re: Are Post-RS errors acceptable? Will VM care?

Most of my channels are fine, but I am seeing some Post-RS errors on the later ones. This is with about 24 hours uptime.

Will I get anywhere by complaining?
If you were getting thousands of Post-RS errors occurring in a short space of time, you may get VM to investigate. But that would probably only occur if say the SNR was out of spec or some other obvious fault. Ideally, you should have no Post-RS errors but I guess in the real world, you’re going to get some at some point.

Yours are minimal so it’s unlikely to be affecting your connection.

I had a thread running a few years ago about the same thing:
