I'm an avid shortwave listener. Sad to say though, the days of getting fresh news on shortwave radio are pretty much gone. You might be able to get BBC or Deutsche Welle targeting Africa but more then likely not a very good signal. Nearly all the Europeans are gone from shortwave, even the once mighty Voice of Russia that used to be only every single band 24 hours a day. Even China even has cut way back on transmitting to the USA.
The few who do target the US like Romania don't really cover world issues but country specific issues. Cuba is on at night but again, mostly focus on Cuban issues but neither of them do live news.
There is one shortwave station, a new one in fact, Global 24 on 9.395 that is just starting up and has a lot of international news broadcast during the day, although reception can be a hit or miss.
As everyone also knows, 3 minutes of shortwave searching will reveal the "The last day prophet of God, Brother Stair" on all over the place 24 hours a day.
AM radio dxing on the other hand will land you a bunch of stuff and during a tour, it's fun to go from day to day and listen to different stations on AM.
