I believe modern police radar works on a doppler effect, (i.e. the expansion and contraction of the sine wave) essentially measuring the change in return frequency from the initial transmission frequency. So, as you drive at a false, then away from it you don't have an exact frequency. Rather you have a range of frequency, and that range will be larger as your speed increases. Not to mention the associated ghosting of those signals, further increasing this frequency range. Also, according to test done by the Veil guy and others, no two belscorts read the same frequency in spec mode for a given source. Taking these factors into account, the 9500 must be locking out a fairly large range in the K and X bands for each false it recieves. Now in a downtown area with many simultanious falses, is the detector locking out a majority of the two bands? Also, for what distance is it blocking the chunks of the frequency band? Sorry if this question seems longwinded or irelivent.
