Good afternoon, I've been struggling with this issue for about a week or so, i finally put in a public request to see what frequency my kids school district uses. Here is what they gave me, but on the narrow band frequencies with the emission designator 7k60fxe and 11K0F3E sometimes I hear a little bit of talking and then turns to this noise. The link is below, not sure how else to show the noise. Any help would be appreciated. Is this standard noise or is it a form of encryption?
