I'm mostly questioning the highlighted one and one omission. I know what the others are, hence why I disabled them for my feed.

In my area, Baltimore, MD, these are the stations coming through via indoor antenna that is ATSC 3.0 certified. I'm using the HDHomerun Flex 4K to convert the signal.

45 is FOX.

I know that 102.1 is ABC's ATSC 3.0 and is not viewable to me via HDHomerun; same for 111.1 in being NBC's ATSC 3.0.

I presume that 145.1 is Fox's ATSC 3.0, but it's NOT encrypted.

So what is 145.100 ? That has the exact same channel lineup as 145.1 and 45.1.

Why doesn't CBS offer ATSC 3.0 yet?
