The second run then I made with the audio of LSB. In the decoding program [EasyPal] all correct pieces of USB-passage were obtained / used. Only the missing or incorrect parts had to be supplemented from the LSB-area What a great error correction! Here is the result of the total tranmission: http://www.rhci-online.de/VoA_Radiogram_2012-06-22.htm received June 22nd 2013 on 17860 kHz in Germany, 16-16.30z roger
