I can't even describe what I am hearing. It is rhythmic in nature. I
am located in North Texas (Allen). Using E1 off the whip. LSB. Can
anyone help?

I'm in Arlington, TX, and I hear it, too. Sounds like digital data. I
don't hear a frequency shift, so it's a ground-based transmitter of some
sort. The signal is not present all the time.
