Do they show up on a TV that has a digital tuner?
It is extraordinary that you would have two adjacent channels so I'm a little suspicious about the numbering.
As we have almost no clue where you live (outside of the channel 9 radio frequency), we can't tell you what you should expect. Have you tried tvfool.com or antennaweb.org to see what all is available?
Are you using lots of splitters on your OTA antenna?
