Actually, there are still some stations to hear but a lot of it depends on conditions. My previous answer was a combination of sarcasm and disillusionment in how SW has dipped and dived after the Cold War, internet, FM reach in the third world, and mediocre propagation has all conspired to reduce the SW bands from their former glory to increasingly empty swaths of spectrum.
On good evenings I can hear the Voice of Greece on 9420. Awesome music. On good mornings I hear Asia quite well, especially in the 49 and 41 meter bands. LIke VK2ZA, I've also heard China Drive, an FM style talk and news program that booms out of China.
The best thing to do is spin through the SW bands and see what's there. If you hear little, try again the next evening... and the next... Propagation changes from night to night. Some nights bands may seem empty, others there will be a lot more activity. It's just nowhere like it was even in 2000 or 2002.
Propagation hasn't been terrific over the past couple of years, and the number of stations decreasing isn't helping much.
At the same time, the former third world still has some SW activity, and if I were in the UK, I would be trying to hear the Middle East and Asia, which are still the target areas of a lot of broadcasts.
I'd also tune the ham HF bands. Sometimes I look at the online ham signal maps and see a lot of activity is present in Europe.
