[Lowfer] Whatever happened to our old Lowfer band?

I was playing around with some receivers in the garage last weekend and also heard some very hot local QRM.
The garage is my only sorta quiet RF spot without putting an E-Probe 33ft in the air. Specifically I heard an
S5 carrier at 195khz. My area is in the process if getting "smart power meters". My guess is that 195khz
carrier was from my local Power CO.
