Decoded fine the 20170226 transmission (text send offline to Stefan). the Eb/N0 is small probably because of some problems with the receiver (it says that 9984s, or almost 3h were padded), probably b

No problem with the decode here, Eb/N0 +7.8dB. The message has md5 hash = df2ba39b3842b67c23a71ebdf466b6cf echo -n 'XXXXXXXXXXXX' | md5sum Timing looks ok, best decode at offset +0.3 seconds. -- Paul
