What would cause a false Ku band alert? From my understanding there is not currently any Ku bands used in the United States. Right? Anyways, I meant to ask this a while back. I had a Ku alert going down the interstate one day for probably about 10 seconds or so. This is the only time it has ever happened and was wondering what would have triggered this. I of course get my fair share of false K alerts and the occasional Ka alert but as I said, only once with the Ku band.
