Coming home from my daughter's art show tonight, turning from an east-west highway onto the northbound lane of a north-south county road. THis is one LONG, STRAIGHT road, but has tons of hills. As soon as I got on the road, I got a K-band hit of 1-2 bars. It stayed steady, ramping up to 4 bars, then it disappeared.
I told my stepson, "he must have turned off the road or something," but I decided to be careful anyway. REALLY wanted to pass the slow, 5-under Honda Pilot in front of me, but didn't want to risk it.
Crested a hill right before the turn onto my road and BAM! 7 bars of K, ramping immediately to full strength.
And there he was, with his nice, reflective markings, sitting in a spot I've never seen them before, shooting us with K-band. I lost the signal and even watched him lower the gun from the window.

Had I not gotten that early hit, I would have blown by the Pilot, and probably been doing 15 over when I got to Mr. Deputy.
WHEW!!
Total range: 3.53 miles, over 4 hills (deputy dog was about halfway up a hill...), with a slight off-axis first-detect.
I am VERY relieved to get this detect. This is K-band country out here, with the local sheriff running about half K and half Ka (34.7) . I had read somewhere that the 78SE was a little weak on K-band, but at least the unit I have is obviously not.
I rubbed Betty's tummy and told her "Good job." My stepson thought I was nuts, but he was SO psyched about the long save.
