Hi Jacek, VLF,

from previous successful DK7FC dec= odes, it looks as if you might also be able to receive a ~10 dB weaker= signal from here (10 uW EMRP). Apparently the rain has ende= d now, so I would like to try an overnight EbNaut transmission with on= ly two characters:

Frequency: 8270.0333333 Hz,
2 characters, 8K19= A, 18 bit CRC (!),
90 s symbols, message duration 9:36 hours,
st= art 2017-02-18 19:00 UT, end 4:36 UT (Sunday) 

The 1/30 Hz= frequency offset has been chosen to avoid mutual interference with th= e announced DK7FC transmission on 8270.1 Hz: With the frequency s= pacing being an integer multiple of both symbolrates, and synchroneous= bit timing, the symbol waveforms should be orthogonal becau= se the "other" signal always undergoes a whole number of 360=C2= =B0 cycles during the decoder's symbol integration interval.
