Anyone been hearing this interference on AM at night?

It's on a few "select" frequencies across the band, but I recorded a bit of it on 950.

It's a rhythmic or pulsating noise, analog to an intermittent traffic light.

Here's the recording I made, though it's isn't very good: http://www.adrive.com/public/03788d4a82ea5a754fccf3f289d793c93f5cc2da920594a91fc3eea45495e112.html

I've already checked and I'm 100% sure the interference it's not being generated here in my apartment. What could be causing it? ???

I listened to your recording and noted that the “pulsating” noise is the two 950 signals that are “pulsating” against each other. They are pretty close. FCC regulations require that they be within 10 cycles of their assigned frequency. This could mean a 20 cycle difference, however, it sounded as though they were within a cycle or two of each other.

To me, it sounded “normal” for an AM nighttime signal.
