The other disadvantage is that the current model can only be used from a stationary location due to the narrow (something like 6' diameter at 1000') beam produced, making aiming critical. Also, there is no "ground scatter" like there is with a conventional radar gun, so determining crusier speed in a moving situation would be impossible. --- Jeff -- -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Jeff DePolo N3HBZ Twisted Pair: (215) 386-7199 depolo@eniac.seas.upenn.edu RF: 146.685- 442.70+ 144.455s (Philadelphia) University of Pennsylvania Carrier Pigeon: 420 S. 42nd St. Phila PA 19104
