I just hooked mine up this weekend. I was using Ant2, but I don't see that being a significant difference. Initially, I was seeing the same symptom but it went away. I am thinking that a power cycle might have enabled something, but I am only guessing. I was doing some contesting on 6M(local) this weekend and it worked like a champ. I also have the sub, and it was also on Ant2 at the time.
