Hi Paul,

Markus mentioned that there may be a time delay of 2 seconds because the periodic actions are obviously counted from 0 UTC and 8:00 cannot be divided by 7 seconds.
The 4th transmission has been done today but i assume we will need 10 or more. Maybe the decode happens on xmas evening! :-)
Can you confirm your system is running and you are interested in the test? Would be a pity to run the TX over such a long period otherwise.

Hi Paul, VLF,

The 2970 Hz coil is back in the shack, for optimisations. I'm reconnected to 6470 Hz and i would like to try a last big shot on the 46 km band using EbNaut:

f = 6470.00000 Hz
Start time: 18.12.2016   08:00:00 UTC (Daily repetition)
Symbol length: 7 s
Characters: 75
CRC 16
Coding 8K19A
Duration: 7h, 31m, 44s
Antenna current: ~ 225 mA


The QRN is very low, so i'm optimistic. I assume you are ready to receive and interested?

73, Stefan
