Once again, my 1793SE did a fantastic job of identifying a real threat from a non-threat.
This time, while alerting very strongly to a K-band signal (7 bars but decreasing, from an initial 9 bars), the unit suddenly switches to X-band and the signal strength changes to 4 bars (and then begins increasing instead of decreasing). This switch from K-band to X-band (YES, the opposite of what you generally would expect given the X, K, Ka, Laser hierarchy) was prompted by the introduction of a NJSP X-band radar signal to the already present K-band "Your Speed Is" sign signal.
The encounter is pictured below:
Non- + Real Threats
I specifically mentioned the hill because there is absolutely no LOS from one side of the blue line to the other (that is the crest of a 20+ ft. hill).
At ~1350 ft. from the K-band sign, the RD's alert changes to X-band (even though the Trooper was 2600 ft. away --> twice the speed sign distance!) and the strength drops from 7 bars to 4 bars (very consistent distance/ alerted strength ratio).
Although not as impressive as my previous story, this is another example of why I'm very pleased with my 1793SE's performance <knocks on wood>.
