launched a new channel, BBS 2. The existing transmission towers are now broadcasting the second channel instead of the first one. If you have a television set with an antenna, you can receive BBS 2, but not BBS 1.
Speaking to BBS, they verified that currently the only way to watch BBS 1 is by having a cable subscription. This is supposed to change in the future, and both channels should be available over-the-air. Right now, however, BBS 1 is not free.
