Definitely not one I've ever heard before. I scrolled through this list and couldn't nail down anything similar. But may be I missed it Digital*Modes*Samples

418 MHz is federal government but it could also be a low power Part 15 device or from some electronic device in your house or neighborhood.

Uhh can't say as I've ever seen anything like it.. appears to be, by my guesstimation, some kind of timing signal..

I'm thinking timing or synchronization signal as well, but it's not on all the time. I'm going to take my SDR to a different location and see if that makes a difference.
