Anyone here from Calgary, AB Canada?

I have my V1 on my car all the time and when I drive by the photo radar vans that are parked in the same direction as the flow of traffic it seems like the detector doesn't pick up the photo radar vans until last minute which of course if you're speeding is pretty much too late.

I have it mounted just below the RVM. I've sent it off to V1 for calibration (Ver. 3.858) and they said they found nothing wrong with it. Even the new V1 Ver. 3.864 doesn't do much better.

Does anyone know how I can improve the detection capability and also what photo radar systems the Calgary Police service is using? I remember when I had my Beltronics 985 in my car in tech mode I swear that it was in the upper spectrum of the Ka band.
