OP here. I don't know why I hadn't thought of this before, but I did a little Googling and found that the two VHFVery High Frequency (30-300 MHz) freq's are registered to an address of a town water supply. Street view shows two water tanks/towers at that address, so I'm guessing this is some sort of monitoring system. Saw your video- the waterfall looks similar, at least, to the one I posted, but it didn't sound to me like the same signal.
