I have it on 065 but that is for my location and might not be for yours, see below.
The way I found this is I went to the ION website, clicked Find ION, entered my zip, AT&T U-verse was listed below, and when I clicked it below that it showed the th ION uverse channels for my zip. If you do the same procedure and don't see AT&T U-verse listed for your zip then sorry, it is not carried for your zip.
ION is a local station in my area and so that may be why I can see it if there isn't a nation wide feed (can see it on my antenna as well). If it is only carried on a local channel that may be the reason you might not see it as possible for your area if it is not listed for your zip.
