One would think they have a meter to adujust all this to the same levels.
Channel 43 in Lubbock uses the same antenna that Fox uses, the same as KLBL and KAMC use the same digital antenna. One of the issues with channel 43 is the existence of CH 44 from a down town tower. It sounds like your antenna is optimized for KTXT reception because of the Amarillo reception you mentioned. I believe your problem is the reception of 44 and amplifier overdrive is interfering with channel 43.
I believe you may actually need a smaller antenna with little or no amplifier (depending on the number of sets feed from the master antenna system.) 7 of the 13 available digital streams in Lubbock broadcast from University between the loop and 98th street. 3 from the Tech Campus 2 from northeast of the South loop and 27 while the last from the north side of town.
Using a shorter antenna allows for a wider reception angle that you require. From your location off of 84 on the southeast side of town you need better than45 degrees of reception angle to receive all the channels in the UHF and a single VHF antenna for channel 11. Digital signals receivers use active receive filters that compensate for miss aligned antennas but there is a limit to how much they can handle. Signal strength is not the problem it was in the old analog days a properly received digital signal will work perfectly with 100 times less signal strength than analog signals. In fact in Lubbock poor amplifiers can create more problems than the help. If the wrong amplifier is used it will overdrive due to massive amount of power being radiated in southwest Lubbock.
