You should only have to do a check switch once, but that check switch must be done on the coax connection where the main receiver is located. That means you have to do the check switch on the main receiver and then remove that receiver and connect the 2nd receiver in that location and start the check switch procedure over again. This will give you the correct SW64 switch on both receivers. Once you have done that then you should be able to fix the problem with the 2nd receiver by simply changing to a channel on the new satellite.
