Want to get more confused? And more OT? HD radio (does NOT mean High Definition). I think it's Hybrid Digital. They have channels with -1 & -2 which essentially is the digital sidebands that can contain different programming. HD radio is causing all kinds of interference problems, especially with night time DX.
They would have been better off going to DRM. Of course that would not be compatible with existing AM. If we ever get the 76-88 MHz range for broadcast, DRM would work well there.

My local Channel 2 is on RF channel 2 on the cable system (a mistake, I'm sure). 4 is on 3, 11 is on 12, 53 is on 7, 22 is on 10, and 13 is on 9. If people can understand that the channel name isn't always the channel number on the cable systems, why can't they understand the same will now be true for DTV where 2 is on 25, 4 is on 51 and 11 is on 48??? It seems that the main source of the confusion is the alias that shows 02-1 rather than 25-1. The very item designed to avoid confusion seems to be the cause. Maybe we should just make it easy and make them use their callsigns again so you can know WTAE is on OTA Channel 4 (STD), OTA Channel 51 (DTV), and 3 (STD) or 210 (DTV) on cable? BTW, KPBS is on OTA Channel 15 (STD) and Channel 30 (DTV). It may show 15-1 as an alias, but it's RF Channel 30 for the DTV signal. Joe M.
