Sn margin

Hi, just a quick question, is it normal for the SN margin down to go up and down?
Eg. From 3.5 db up to 5.4db and then settle back down to 3 or 4.I've never noticed before now.
Thanks in advance
John

Re: Sn margin

if that is over a 24 hour period then it is

But if it is jagged bursts it would tend to indicate an interference source
