North Korea strong in Japan
On the Japan Perseus remote receivers you can see how active the North Koreans are. Of course you can get some of their SW services here. But there, they're all opver the SW band. I tuned over 25m on a Japanese morning. And Chinas domestic services all over the place of course.

Wide AM in Japan
It also occurred to me again that 2 x 10 KHz wide AM modulation is the common standard in Japan. Sounds much better than our strict 4,5 KHz limits here in Germany.

pirates extend their range
Just tuned the so called 48m band. Some pirates there, mostly Dutch I guess, as to expect on a Sunday. Some years ago they were concentrated between 6200-6300 khz. But not anymore it seems. Some were on 6385, 6450. And 6930 /6940 have become common frequencies, too.

Australia without interference
Things have changed since the 80ies. Back then it was rather difficult to get Radio Australia or New Zealand because the SW bands were full. Now it has become so easy. Just listening on 11945. Clear frequency. Nice audio.

new AM bandwidth record
While China regularly modulates with 2 x 10KHz audio I just came across Radio Rossii on 12075 KHz doing 2 x 14 KHz. Needs to be notched at 5 KHz. But a good experience. But even there is SAM mode, fading still disturbs the audio. This is the main field where DRM could gain score. On the other hand, AM signals never completely disappear in difficult situations while DRM would abruptly stop. In the spectrum you can clearly see the fading lines and the fact that audio is cut above 4,5 KHz by some extent.
