The TX was on air all night. However for some reason the transmission didn't end automatically at 6:39 UT as expected, but continued until an external mechanical timer switched off the power around 6:49 UT. Possibly something had gone wrong with the sequence timing. I will try to repeat the experiment soon.

Another low-power EbNaut transmission from here:

Frequency: 8270.0333333 Hz,
2 characters, 8K19A, 18 bit CRC (!),
60 s symbols, message duration 6:24 hours,
start 2017-02-24 23:15 UT, end 5:39 UT (Saturday) 

Best 73,
Markus (DF6NM)
