I thought this both timely and interesting as the US will be experiencing a solar eclipse on August 21. Page numbers 20-plus go into detail about signal reception of a Swedish transmission on 6065 am as received in Spain. At my location, we will only have 70% totality maybe it will be like early dawn/dusk conditions here. Might be some unique receptions that day.
