I tried a few things.
If both 9 and 29 are in add state.
Can get: 9.1 and 29.2
If 29 is deleted.
Can get: 29.1 and 9.1
If 9 and 29 are deleted.
Can get: 9.1 and 29.1
If 9 is deleted.
Can get: 9.1, 9.2 and 29.1
I'm doing a few recording test. Just one minuet recordings to see if this is what you want. With 9 deleted you can record 9.1, 9.2 or 29.1.
Since you don't get 9.1 in well. I think you want only 9 deleted and record 29.1 or 9.2.
TPT 2 and KSTP 5 have similar issues in the MSP market.
I think you have your 29 information switched and it should be:
29.1 is HD MyTV on physical channel 29
29.2 is SD MyTV on physical channel 9
They would only pair a HD programming with a SD and not have two HD programming on one RF channel.
For more information I would use the thread Minneapolis, MN - OTA
