Just some observations about the updated ramp up:
X & K ramp seams to be almost as good as the X50 but it seems to be a bit more active on fast approaching/threatening radar and ramps up a bit quicker in those cases. Now thats a nice improvement!
1st Radar from a gun can get your speed in the best conditions at approximately a maximum of 3000ft in moving mode, and a maximum 5500ft in stationary mode. In most cases moving radar has about Ĺ the distance of stationary radar so the reaction from a RD should be different.
There have been reports that when K & KA is moving toward the 9500I it ramps up very quickly (moving mode) and when K & KA is not moving (stationary mode) ramp up seams normal. Allowing a more active ramp up to warn you better against moving/faster threats.
The 9500I seems to be more active in its analyzing radar, the ramp up increases faster when it encounters a fast approaching radar increase (moving radar) over a normal ramp up for (stationary radar). The 9500I does have GPS, so it is certainly possible that itís analyzing the incoming radar to see if it increasing in a faster rate (moving radar) than what it would if it was increasing at a slower rate (stationary).
I think the new ramp up is made to react more sensitively to fast approaching radar to produce a slight edge over a slower ramp up on slow approaching radar and has nothing to do with GPS, but anythingís possible.
