i thought i was the only one having this problem. have a post on here from couple months ago,and i am not going to rehash,but nothing has changed.did have a service manager and a precision tech tell me to throw all that stuff out of the cab and go plant.they are probably going to get their wish.hope you have better luck than i have.a good read on how rtk and satellite guidance works,is the state of iowa cors site,it alls sounds pretty simple,but alot of things have to be right for it all to work
