Hi Stefan,
nice work! Diving into the spatial
stereo sound in headphones is really awesome.
Despite the fact that you are using only one loop
yet, it looks like one can already get a basic 360° colour-DF
display:
Despite all theory, it seems to be possible to
crudely discern north and south (eg IQ2MI in yellow). Perhaps the loop
is somehow receiving a small quadrature-phased contamination in the
null directions.

Subject: LF: MF stereo stream available for all
Hi all,
I was playing with my
new Raspi 2B and installed the darkice audio streaming software as well as
Icecast2.
As a test i fed the stereo AF coming from an other PC (which is
reading my MF remote RX stream and playing the AF to the headphones) to the mic
input. This is now streamed to http://129.206.29.30:8000/Raspi4
Sounds complex? It is!
At least you can now listen to the stereo
stream if you like. In SpecLab you can read, display and frequency shift the
stream. For the SpecLab configuration, see for example: https://dl.dropboxusercontent.com/u/19882028/MF/stream.png
It
is interesting to listen to a loop antenna on your left ear and to a
vertical (T) antenna on your right ear to the same time :-) Sounds a bit
3-dimensional...
There is a time delay of a few seconds due to the series
configuration of 2 web streams, so WSPR decodes are not possible without some
tricks...

PS: The steam will be available for a
short time, maybe until tomorrow...
PPS: Attached is an USR file which helps
to prepare SpecLab
