Hi Luis,
Thanks for your interest.
There are a lot of settings to make before SL generates the necessary
txt files for ebNaut decodes. I can send you a configuration file for
SpecLab later.
But i think it makes no sense at that stage for you. There is a
sequence of steps to be done before there can be a success. As long as
you can't see my carrier there is no chance to decode that message.
Also we should start with much shorter messages. 12 characters is
already a bit a challenge for the stations in a range < 1000 km.
Stacking many days will help of course.
We could start using a 1 character message or 2 characters.
Your 47 uHz spectrogram already shows changes in the day/night QRN,
which is a good sign. But it looks to me that the difference should be
higher, i.e. it looks like you are missing some sensitivity. You know,
it depends on the location of the E field probe and the sourrouning
objects such as trees. Also the high pass cut off frequency plays a
role. And of course the local QRM which reduces the performance of the
noise blanker.
What about your remote RX location in 7 km distance from your house?
Isn't it even near the sea?
Can you describe the rx system that you used so far, and the location?
Sorry, we may have discussd that before but maybe there are some
changes that i missed.
I would like to reach that goal with you, not only on 8270 Hz. And i
think it is quite realistic!
73, Stefan
