Working event medical over the last weekend. The radios we're using pick up other traffic if the squelch isn't set right. One of them was set wrong, and so as a result I suddenly hear something that sounds EXACTLY like the Motorola 800mhz trunking alert tone that we get at work -- you know, DOOP DOOP DOOP. I jumped about five feet in the air, and everyone else thought it was hilarious. It was, of course, nothing.
Anyone else have those wonderful tone-related experiences?
