0739 bass beat, some splashing QRM
0805 heard via Weston SDR : bass beat music 0904 the same

1402 via Twente : bass beat, noise filter works
1406 via Weston : signal a bit stronger, but no noise filter found useful
around 1530 : the best KiwiSDRs are in the Hannover-Hambourg area, also found some good results around the Grand-Duché (but not many SDR to try there)
1703 was below King Shortwave
1830 alone again. Nothing to do with Radio Kahuzi ! Probably from the Netherlands
