If my memory serves me correctly,back in the 2000's I nailed South Orange Nj police on their old vhf frequency. 46 mile's. I believe I was using a GRE psr-500,with the original antenna. I think their repeater was on South Mountain Reservation. In my personal experience,GRE/Whistler kick's nearfield capture over Uniden. However it is more susceptible to overload.
