I've wondered about that. For what it's worth, when Montana PBS went S2, I replied to an email sent to me by their then director of development, told her that I had upgraded my receiver so I could continue viewing them. She replied:...Sometimes I visit with a technician who oversees one of the PBS stations on 125.0W. He is reserved in his comments but I sense that he doesn't approve of the FTA hobby...
"Terrific! We worried about some of the folks who receive us this way."
I should hope PBS in general would be pleased with us, but suspect the good feelings are not universal within the organization. Which is really too bad.
