I do not how to find the ral channel numbers.
The real channel numbers are listed on your tvfool report, but not all the virtual numbers, hence my confusion. I had to hunt for them on rabbitears.info

The virtual numbers are a holdover from the analog TV days, and the stations want to retain them for viewer identification even when they are no longer the same as the channel used by the transmitter.

They are both subchannels of the same transmitted channel. I doubt that they will ever be 100% reliable for you because that channel is weak, has co-channel interference from another channel 40 transmitter, and is a 2Edge signal with terrain obstructions. Click on that channel callsign in your tvfool report to see the terrain profile. Your antenna is aimed in the wrong direction. A preamp might help.

I am always amazed when someone wants a simple system that duplicates what a CATV system headend does with multiple antennas, amplifiers, and modulators costing thousands of dollars. You will need to cut back on your expectations and settle for improving one direction or be prepared to spend a lot of time and money building a system that does what you want.

I have no idea what that is; you haven't given me enough clues.

If you get 69.4 you should get 69.1. They are both subchannels of the same transmitter. Your antenna is aimed in the wrong direction.

In order to avoid a rotor you could add a second antenna aimed in another direction. Combining two UHF antennas aimed in different directions doesn't usually work because the when the two signals from each antenna from the same channel arrive at the combining point, they can interfere with each other if they don't arrive in phase. You can use an A/B switch to select which antenna you want to use, but your DVR tuner must be able to add a channel after scan to avoid rescanning every time you change antennas. An alternative would be to have two DVRs, one for each antenna.
