OK, so most of you probably remember one of my early tests of this detector against a Your Speed trailer in a construction zone on North Powers Blvd here in the Springs (http://www.radardetector.net/viewtopic.php?t=25971). I didn't have the best of luck, but wondered just how much terrain had to do with the results.
Well, this week they moved the Your Speed trailer to the south end of the construction zone on Powers, facing south. That placed the radar at the TOP of a hill instead of at the bottom. I discovered this while out driving with my daughter Friday, getting excellent detection as I approached from the rear of the radar, southbound.
So today, when I had to run to Home Depot (since LOWE'S didn't have what I needed) up north of that construction zone, I decided to play a little and see where I got the signal.
The Pro-78 surprised me again.
I got first detect at the peak of the hill just south of Stetson Hills. It gave me a strength of 1, which ramped briefly to 2, then faded as I went down the hill and was out of the radar's line of sight again. It started again part way up the hill north of Stetson hills, ramping very nicely from 3 all the way to full strength about a tenth of a mile from the radar.
First detect distance: 2 MILES! Two miles on a weak signal from a your speed trailer. Impressive.
Yet as I turned west on Woodmen, well north of the radar and out of its line of sight, my Pro-78 ramped up again. Sure enough, they had placed a SECOND trailer on the south side of Woodmen road, shooting west.
*Insert Evil Laugh Here*
So I bought my 2' X 4' sheet of subflooring, stuffed it in my trunk, and drove a couple miles west, over a hill from the radar. Flipped a U-Turn and headed back.
This time, my Pro-78 alerted at the crest of the hill west of the radar, around a slight bend. It maintained alert, ramping from 2 all the way to full strength in a nice, gradual manner. It did ramp DOWN from 5 to 4 when I was headed down the hill, but that only lasted a moment, and then it ramped back up.
Range on this first alert: 1.5 miles, around a bend. Another fantastic detect!
The first thing this showed me -- TERRAIN MASKING RULES. Do NOT speed on downhill, around the bend roads. ICK.
It also showed me that this thing has some VERY good K-band sensitivity--probably 30% or so better than the Pro-73.
Wow. Now if only every other damn door opener in CO wasn't K-band....
Thanks to the CSPD for setting up such a fantastic course for me to test my RD. Hee hee hee.
