Here on the Woodbury, LI system, all three sub-channels for WLIW-DT are carried but they are SD because WLIW is broadcasting in SD. The OTA signal for WLIW-DT is SD on all three channels.
NJN is available here on channel 107-8 ClearQAM but not through a box (at least I have not been able to find it on a box). The NJN OTA signal has three sub-channels; main HD program on -1, secondary programming in SD on -2 and an audio only reading service for the blind on -3. -- I support the right to keep and arm bears.
You would figure NJN would mention it directly having an their main OTA signal in HD, gotta wonder why it's not carried....atleast on Cablevision in HD. I already knew WLIW was SD on all three of their channels. So we're both missing each area's respective PBS station on our IO lineups.
