I just received my Bell RX65 today and decided to test the two against each other at a school speed sign. I had only 1 unit on at the time, and circled the block several times.
As I reported earlier, my V1 3.818 didn't pick up speed signs. The RX65 started picking up the speed sign ~1 mile away. The RX65 indicates that it's K-Band 24.152 in Freq.
The V1, in "A" mode, with no custom programming, never ever beeped. (I had the unit in "L" mode almost all of it's life.) It was dead silent all the way through. The sign showed my speed at about 100 yards away.
I'm going to pickup my Dad's V1 tonight, and try it tomorrow when school is in session again.
All this time I though maybe the LEO instant on'd me, used POP or lied, but it looks like it's possible he had it on all the time, and like an idiot drove right into his trap.
I can't say the unit doesn't pick up K-Band altogether, since it reports K-Band on doors all the time.
Here's my first post about it: http://www.radardetector.net/Nailed-...ing-15826t.php
