Not quite enough to decode. File start is 2017-03-04_23:10:11.91 TX start is 2017-03-04_23:30:00 The offset should therefore be 1188.09 seconds. But Eb/N0 actually peaks at offset 1196 seconds. With 1188.09 offset, Eb/N0 is down to -5.5 dB. Checked TX timing here: Stefan's transmission has its usual approx 0.3 seconds delay. The extra 8 seconds must be due to RX timing. -- Paul Nicholson --
