It used to be that the 7 to 10pm slice was prime listening for Americans as foreign stations would choose appropriate bands to employ to send to the US. Sadly, the vast majority of Americans view shortwave as archaic in the age of the cellphone and innernets.
The foreigners realised few Americans listened to their bcasts so they dropped them to North America, reduced them greatly, or went online. Only the poorest of the poor in the world don't have a smartphone with innernets, and these poorest of the poor remain as targets for shortwave broadcasters as they still use portable am shortwave radios to provide information and entertainment. If only it wasn't so expensive to burn megawatts, use huge costly antenna arrays, and of course pay the slick professional talent for producing radio programming.
That being said, I like the 9Mc and 6Mc bands as well as most of the others for dx porpoises
