Thay've been there for months, I've noticed alichip receivers don't scan in all tp all the time. Manual insertion of tp info is required many a time with these receivers. Those channels used to be on 53w but moved over to 55.5w a while back.
Whenever I post an Arc thread I scan all known tp on lyngsat for each individual sats that the receiver hasn't scanned in. You'd be surprised how many tp they miss.
