HD RadioFirst... Here are some important differences between digital and analog signals to note!
1. A station's digital coverage area is typically a little smaller than its analog coverage area.
2. While you might have static on the edge of a station's coverage area listening to its analog signal, there is NO STATIC listening to a station's digital signal. That is the nature of digital reception. It's either perfect (no static), or it's non-existent, and the HD radio reverts to broadcasting the analog signal.
3. HD signals actually have three "channels", HD1, HD2 and HD3.
HD1 is typically used (as WDCB does) for the "real-time" broadcast. It is identical to what you would hear on WDCB's analog signal.
