"can I use the channel numbers to match the channel name instead of the call sign letters?"
If I remember correctly, on my first scan when I received the tuner, about 80% of the newly scanned channels displayed call signs with channel numbers to the right of the call sign. 10% displayed channel names with channels numbers to the right of the channel name. 10% just displayed the frequency with sid numbers.
Maybe some one else can chime in with their percentages.
