Yes, I guess that is where the confusion has come in. On Galaxy 27 there is White Springs TV, which is linear, and there is
PBS out of Athens, which is circular. I thought I could just set the switch and it would scan the linear and then go on to the circular. If I scan both in using different settings, then can I just tune in the station and the receiver will change to the correct frequency? Thanks, this has been a very interesting month or so, trying to learn enough to keep the tv on.
