You are less than 5 miles from everything. KAMC, KLBK and KJTV are SSW of you, KCBD is about 15 degrees east of them. Your only "problem" might be KTXT which is behind you if you look at the others.
Perhaps , since I am closer to KTXT , I am picking it up on both the back side of the outdoor antenna and the rabbit ears .
I have a Radio Shack U75-R ($25) pointed at KAMC/KLBK because they are the weakest transmission (both <1kW). I am a couple of miles further out than you are so I had to add a Winegard HDP-269 pre-amp to pull KAMC/KLBK in. I am 2 miles from KTXT and pick it up off the side of the antenna with reception in the 90's.
My RCA SDTV does not have a user signal meter , like a FTA receiver . :-(
Or I have not been smart enough to find it in the menus . :-(
KJTV-DT is working on their new transmitter/antenna/encoder to get it to work with all receivers. When they fired it up it caused severe pixellation and dropouts on DishNetwork ViP 622 receivers.
On DN receivers ?
FOX 34 ?
Think I am picking up FOX 1, 2 & 3 , will have to check . Picking up NBC 1 , 2 & 3 , and PBS 1 , 2 & 3 ( although PBS 2 seems blank ? ) for sure . Sometimes ABC 1 & CBS 1 . All on the rabbit ears .

Are most / all of these stations broadcasting low power ? you mentioned less than 1 kw ?
When Mom & Dad lived in Floydada , I helped Dad put up a medium / big antenna on a pole 5 - 10 foot above the roof of the house . They got the " big 4 " networks pretty good . PBS was always week .
Now I hear you say you are having to use a pre-amp , with in the city limits ? Will the stations ever turn up the power to the level they are currrently using for analog ?
Thanks ,
