I tuned in to hear “Eye on Travel with Peter Greenberg” talking about the 737 MAX troubles, which I matched with WCCO’s online stream. The fair signal slowly faded over the next 15-20 minutes, but it stayed mostly on top of KNCO in California; I heard the show come back from the break at 0733 UTC.
This clear-channel station runs 50 kW; the distance is 1,371 miles from me. My new Eton Elite Field, paired with the Tecsun loop, is indeed pulling in MW stations my Grundig Eton Satellit doesn't.
