I've got my radio stopped on this frequency but I haven't heard anything else yet. I had it on CTCSS tone search and it kept jumping around to different tones.
DPL?
Want to have some fun? OK here you go there is a cool application that I use for a number of audio analysis
tasks it is called spectrum lab, aka spec lab, available here

I must warn you this is not an easy application to use, when you work with some of the advanced features this is a very powerful program, "out of the box" it is fairly easy to "see" what is out there.
just plug your scanner audio into your sound card line in, select the correct sound card and source, start the program, click the start sound thread, it should start running, you will see something like this.
the dark area at the bottom is no input (scanner off), the blue and black area with the red streaks are scanner on, not receiving, you can see I have a noise issue, the brighter area with reds and yellows, is scanner on, receiving traffic.
