[Scan-DC] Arlington Police Locate Missing Elderly Man UsingLoJack

I can tell you, the range on the people transmitters are not much - if I remember correctly, its about 1/2 a mile or so. 

The sounds you hear on the receiving device is a beeping. The beeping gets faster or slower depending on how far away you are from the transmitter.

OK, so I've programmed in the LoJack frequency below, and it's doing something, because at regular periodic intervals I'm getting a squelch break - possibly a data burst, as it sounds similar to the MSP helos' locator beacons.

But, what kind of signal / modulation does it use if it spots something?  In other woids, what does it sound like?  Also, what's the range?

Thanks!
