A country always in the news is Iran, who put out a decent signal that can be heard in the UK. I find many of their programmes to be of considerable interest too.
I tend to tune into VOIRI for the hour from 1930 UTC on 6010, 6115, 7320, 13670 or 15450.
There are other times as well for English from Tehran. For night owls try the 0330 to 0427 UTC Voice of Justice broadcasts on 7200 and 7365kHz; then mid mornings 1030 to 1127 UTC on 21575 and 21695kHz; and mid afternoons from 1530 again for 57 minutes on 13785 and 155525kHz. http://english.irib.ir
