...The signals are visible as two faint traces arround 6.5 kHz on my
tree grabber, see attachment :-)

Hi Paul,
Probably you are the only one who is able to pick up the message that i
will try to send soon. I'm not sure if your RX is running, i just give
it a try.
There has always been the question if it can make a significant
difference, due to propagation effects, if the transmit frequency
varies by just a few 10 Hz.
Thus i'm now running an EbNaut transmission on 2 frequencies, sending
the same message (parameters) and the same antenna current from the
same antenna:
f1 = 6430.005000 Hz
f2 = 6510.005000 Hz
Start time: 16.October.2017 13:00:00 UTC
Symbol period: 15 s
Characters: 2
CRC bits: 6
Coding 16K21A
Duration: 2h32min
Antenna current: 200 mA, on each frequency
I can repeat the message at night but let's give it a first try. Jacek
asked for a similar test some time ago. He will need a night time
signal i think.
