I'll take your word for it.  But I have seen many spectrograms of 
modulated carriers that look exactly like that, especially AM.  Tune 
1KHz off from an AM station and that is about what you will see.... a 
carrier at 1KHz and information on either side of it.

Again, I was just curious because that was what it looked like to me.
