It may feel strange that I’m about to suggest looking for North American DX during the Summer heatwaves in NW Europe.
But that’s exactly what I am going to do.
Unsurprisingly most DXers look for US daytimer signals in the winter. But between September and March DX opportunities are set by the position of the terminator between day & night – where there is more darkness at higher latitudes in the Northern hemisphere.
However between April and August the opposite is true – there are fewer hours of darkness at higher latitudes in the Northern hemisphere.
This fundamental difference means that opportunities for trans-atlantic daytimer DX are very different between August & September.
If you are interested in a challenge here are some stations that could be heard in the final week of August.
More southerly daytimer stations in the USA have an advantage before the Autumn equinox. Simply put, that is because sunset arrives in Florida earlier than in more northerly latitudes. Another way to express it is to note that Miami has more hours of darkness than Toronto does before the Equinox; after the Equinox the reverse is true.
The following stations might be easier to hear in late August than after the equinox. (The times shown are when the station either reduces power or closes down in August.)
Good luck!
