After a channel scan today, one station is missing (RF 21-1, virtual channel 30-1). Nothing wrong with the antenna as all other channels are full strength and the missing channel but can be received directly on the TV tuner. Any ideas?

Trip is aware of the short-lived sub (BizTV) using AVC in my market. The engineer removed it due to issues getting the EAS to work, which may or not be related.
