Do you not mean SNRM ? Because if not there's something amiss somewhere.

Sorry, Yes we are talking SNRM.

Is that not what the thread is about?

One, SNR, is the actual targeted figure, the other, SNRm the amount 'spare' over the target.

If your SNR was actually hovering around 1db it would be in and out of sync like a fiddlers elbow .... but other stats show the connection as up for a good while.
