Tom, I'm having the same problem as you are. Didn't have problem on a shorter coach, but now I get an error code on usually one of the duels and maybe a tag. I just check the tire beside it and if it is running at normal pressure, I feel all is well. Then in a few minutes all is working OK again. I think that Forest is correct in that we need a repeater Antenna, which I think one is sold by PP. Chappell
