OK, copied 40 chars:-

The message is correct! :-) That's amazing. Now i thought back to 2010/2011.
Signals were 20 dB stronger but now we can manage 40
characters in less than 5 hours. This is 270% of the message length in about
1/9 of the time needed in October 2016! With that
signal we could manage 100 characters in one day, about 11 hours.
Last night i run another message:
f = 6470.100000 Hz
Start time: 19.Apr.2017 19:00:00 UTC
Symbol period: 30 s
Characters: 2
CRC bits: 20
Coding 16K21A
Duration: 6h, 56m
Antenna current: 460 mA
This is a chance for G3ZJO and RN3AUS and SQ5BPF. I generated EbNaut RX files
from the tree, the message decoded without a single
bit error.
