...85 % of the message is already through, i.e. 0.7 dB missing. So far
no problems. I hope there will be no interruption of the PSK again.
The PSK can be followed at
http://www.iup.uni-heidelberg.de/schaefer_vlf/DK7FC_VLF_Grabber2.html ,
as usual.
Tell the message, if you got it!!
BTW, i confirm the correctness of the two recent receptions by SQ5BPF.
Well done!

Hi Paul and Markus,
Great results! Thanks for the reception and decode.
Well, let's try something for the record list again:
f = 8270.100000 Hz
Start time: 24.May.2017 20:00:00 UTC
Symbol period: 10 s
Characters: 160 ( 1 SMS length :-) )
CRC bits: 10
Coding 8K21A
Duration: 22h
Antenna current: 700 mA
It is a challenge for the DL0AO cardioidal antenna looking
towards
the west :-)

A couple of easy decodes of the very strong signal
from Stefan.
