Hi Alex, Paul VLF,
Thank-you Paul for the summary. It is looking a little more favourable
for a reception to the west.
One of the letters you decoded is correct, Alex. I will try again
tonight, same message and parameters, unless the bad wx in the forecast
brings down the aerial.

"," - also from stacking
"8"

"S"
with rank < 20
and also "K" or "T" with high rank
Unfortunately I do not know about true message.

Hi Markus,
Yes, LF and VLF at the same time.
The 2200m tuning coil was getting in the way in the shack so it was
returned to the base of the tower where it belongs. It is good to
see the nice blue colour on your spectrograms again.
73 and GL with VLF tonight.

Hi Joe,
you have a strong QRSS signal on 137777 Hz - are you sending LF and VLF
simultaneously?
Best 73,

Thanks for all effort put into this, and nice to hear about the TA reception
via my remote receiver at DF0WD.
Spec Lab and EnNaut are where the real effort went; I just tinkered with
hardware! Thanks to you both and to to all who worked hard to set up
and opereate the RX stations and sent reports today: Riccardo
IW4DXW, Wolf DL4YHF (DF0WD) Markus DF6NM (FL0AO) and Jacek SP5BPF.
There will be another repeat transmission tonight.
