Wanna know when the planes are near ?? Use Jeff's advice and "scan" for the police band used by these suckers. In California the freq. used is 42.340 MHZ. Almost all Scanners will recieve this freq. It is used mainly for any Statewide activity and bulletins (I think). The Air Bears here are part of a Statewide task-force and as such stick to that freq. -- I've been monitoring them for a time and have found out a little of their habbits, i.e. they start work just like you and me at a certain time. They take some time to set up and this is co-ordinated on the ground by the plane. The plane can be heard for MILES. If you hear your cars description on your scanner there still might be some hope for you. Try to make it look like you are just passing a car, then slow down to a reasonable speed. I've heard the fella in the plane call off a few patrol cars for this reason, May be your lucky day :-) Maybe Time to go to Tahoe. -- When I vacate my hometown to relax for a few weeks I usually carry a scanner tuned to the above mentioned freq. and listen for static. This is a tipoff in a big way as mostly everyone around here drives like hell and someone is being picked off regularly (lots of radio activity from the plane). Shit if I had a plane and a badge I would go into the business myself, looks really profitable :-) -- ------------------ // -----------Cut-Here---------------------------------- Erick Parsons // Words for the wise: *If it works don't fix it.* Sacramento Ca // mail to: ...pacbell!sactoh0!americ!erk ------------- \\// --------------------------------------------------------
