Lately I have been using spec meter to try to determine what brand of Ka guns are being used along my commute to/from work. My question is this: When coming across a CO Ka signal near 35.5XX, why does the display change to something near 33.7XX just as the LEO passes traveling in the opposite direction? Both Kustom Eagle series and MPH units are used here. This topic was touched on in the past by search, but I didn't see a clear answer. X50 rev 5.
