Basically I want to know if anyone knows if the speed signs are low powered, and here is why I ask. I was driving east through a construction zone, I get a K alert about 1 mile in advance, the drone was facing me when I passed it. About 2 miles down the road in the same construction zone, the traffic traveling west had a KA drone on their side of the road. I got about 100 feet or so past the KA drone and my V1 goes off, but it never got to full strength, even though there was plenty of cars for the signal to bounce off of. I was a little concerned.
I then got back on in the opposite direction, to drive towards the KA speed sign. I got 1 dot .9 miles away , (on a flat surface) that only lasted about 2 seconds doing 55 mph (construction zone) then .5 miles before the sign, I got 3 dots that again lasted for about 2 seconds. About .25 miles in front of it, my V1 held the signal but never got to full strength even when I passed it. I noticed that the speed sign was not displaying any speeds. I got to thinking it was one of the FM-CW signs.
So I got my POS old Bel 925 express out, and this time did some testing on a side road about 50 feet from the interstate that has the KA sign. I drove by a couple of times with just the Bel on, and it never got higher that 3 on the ramp up. As an experiment, I turn on my V1 with the Bel on (I know it is not recommended). About 2 seconds after the V1 alerted to the KA sign, the Bel goes off and holds the KA signal longer than the V1. The V1 junked the Bel (or was it the sign?) out after about 5 seconds and did not report to the KA sign. I appears that the V1 only junks the Bel out when the Bel gets a KA alert, not K. Anyway, after experimenting, I was wondering if the KA speed signs are low power. I also wonder about the K signs too, only 1 mile of range for constant on and is there a better way to test my V1 with KA?
BTW, I got a K alert from a PSP trooper using instant on about 20 min before that. I have V 3.863 and always in A mode. Construction will last a while, so I will have plenty of time to mess around with it.
