As I recall, the Samsung patch had something to do with the broadcast flag
being set. Doug sent me his kit to update the unit I have in my office.
Still have it, if anyone needs to software update their Samsung SIR-T151.
Call the offending station, ask for the Chief Engineer, and ask her/him if
they recently set their broadcast flag on 4-2.
