I have noticed the outage since about Saturday, but I am uncertain about the cause. What I do know is that when I went by the transmitter site in 2019, a “FOR SALE” sign was posted. This property is in the South Hillsboro residential development area.
With KUIK off the air, I did some lunchtime DX yesterday. I noted that the groundwave signal from KAST (1370) at my location near downtown Hillsboro was much better than that from KSWB. Both stations are 1 kW. I guess that the terrain on the way to the coast does some odd things.
