Listening to the 15 meters amateur radio band

Conditions on the upper HF bands have been pretty good for the last few weeks. Many stations (including broadcast, utility, amateur, etc) from all over the world may be heard even an hour or two after sunset. Yesterday, I finally managed to spend some time scanning the bands at the LZ2II's station and listened mostly to 21MHz (the 15 meters radio amateur band). I was able to hear stations from most of the States with solid 59 signals. Here are some of them:

1346 - K8CCD (57) - A92HK (59)
1348 - W1HI (59) - A92HF (59)
1349 - W4UW (59+10dB) - A29HK (92)
1354 - W4UW (59) - EA2BY (57)
