Hi Stefan and Markus
Stefan - The antenna is an e-field probe about 4m high with a pre-amp to
your design - I've modified the filter very slightly to bring up the
gain a little around 9kHz. The probe is a few metres away from the house
to cut down on noise. I'm in a small village about 6km east of St Neots
in Cambridgeshire - the garden and antenna happen to be next to the
small village church and graveyard - whether this has any effect on the
signals I'm not sure but the neighbours are quiet! I can now see the
start of your DFCW-600 message.
Markus - I wondered if the upper trace was you - so very pleased that
you've confirmed.
I'll continue monitoring and will post more screen shots later.
Congratulations to both on excellent signals.

Dear Chris,
I'm surprised. That is excellent! The best capture i have seen from
the UK so far during my tests from the fixed antenna. Very impressing.
You must have an excellent receive location. What is your RX antenna
please?
So then you will easily receive my short message, even with the
glitches i produce.
Many thanks.
698 km BTW.

Hi Stefan and VLF
Here are two screen shots of your signal with me in 600 and 6000
windows. Both good signals with the 6000 peaking up to 15dB above the
noise.
Must get dropbox sorted out!
