Perth, Australia - the only thing I've positively ID'ed here is 2QN Classic Hits over in New South Wales (2kw, about 1,700 miles East of me). It's the only Aussie on the frequency. It's usually just mush underneath - there aren't a lot of stations of higher power in Asia on 1521. The only high power Chinese is way up near the Kazakh border in far NW China.
I've been surprised that I haven't heard 1521 Saudi Arabia here, but looking at that tower photo, it looks like I'm in their null, which could help explain it.
