OK, copied 40 chars:-

 "CQ CQ ON THE 46KM BAND DE DK7FC JN49IK K"

Carrier Eb/N0: 0.0 dB
BER: 33.8 %
List rank: 0
Carrier S/N: 23.5 dB in 57.0 uHz
Carrier phase: 66.2 degrees
Reference phase: constant
Decoder memory: 71.8 Gbyte
Decode time: 308 seconds
Bits per hour: 46.8

A nice result at about 73% of capacity. Carrier phase
of the decode agrees well with yesterday's phase
measurements.

It was a bit too big for my workstation so I used AWS
