Sound clip here:

I recorded this in the AM mode because more of the sound could be heard in that mode but I suspect it isn't really AM. In the USB mode it sounded more like a fast tick tick sound.
The signal was quite strong with occasional fading but it never dropped any wheres near the noise level. Any ides?
BTW Some of the sounds I have been hearing that sound like OTHR but remain on one frequency remind me of the sound of an MRI machine. I know all too well the sound of an MRI and I will be getting a refresher course in about a weeks time <sigh>
