A couple of observations so far:
1. Ka band false alerts. There are tons of them.....34.3, 34.7, 34.9, 35.5. I probably had 10 or so today in about 3 hours of driving. They're not as annoying as they are on a Whistler though, since they don't come at full blast(Ka9), but they still happen a lot.
2. I don't think there's any way to turn X and K band totally off. I have it in "city mode X+K", but any strong X or K signal overrides the suppression of the signal via city mode.
3. So far, this unit does seem to get the band right, so that's a positive over the last Cobra I tested.
4. I have some nice Stalker II I/O action I have to edit the video on, so that should be in the video section sometime tonight.
