Well I took the V1 on a trip to my aunt and uncles today, and I encountered the much rumored Ka band speed sign... and luckily since we was going to a family get-together, the fam. brought a camera with them...
So I took it for a second and went down the road and had some fun, and decided to post them thinking you guys (who havent seen Ka speed signs yet) would like to.
Its tough to see (blurry), but anyone who has a V1 should see that it most certainly is Ka (in reference to how far it up is on the Front arrow).
-Also note the sign is very obviously on, however, it wouldnt display my speed under 15MPH.
The range was ~.1-.2miles, around a 170degree bend in Suburbia, not great and not terrible.
