From the first alert on a familar travelled busy street to the point where the local leo bike cop was writing a ticket to a speeder, I had a alert distance about just 2.5 miles. I just thought it was a cobra owner driving next to me and it was pissing me off but i also thought it was a weak signal but very very slowly getting stronger. On this stretch of road the 7-11 emits a k band signal and stops right after I pass it but the k band continued getting stronger until I could see the leo off the bike and was finally at full alert just a few hundred feet to the bike and the signal stopped about .15 miles past the bike cop. I could see this happening on the hwy but in a busy area? Was the radar gun at full strength? But whatever reason that is great range on k-band in a business area.
