[Scan-DC] another signal question

[jay]

I keep hitting on 169.425 with a constant tone carrier with occasional
packet data? What is this? I'm getting it S-6 w/o pre-amp. I made a
recording and a spectral analysis. It seems like the high pitch tone
is the center lock and everything else happens around it..

here's the mp3.. (2 MB)
