Hi all,

Next step is the solar charger and then the Raspi, remote linked...

Hi Stephan,

...
Sorry, this is mostly OT but i know there are a few OMs interested in
remote sites for VLF/LF/MF bands

Off topic? Don't think so.

and this may be useful for them and so
for us, if they will realise a similar project.
...

Agreed.
Question: anyone out there having some
experiences running the "Wolfson-Card" on
the Raspberry-Pi? I'm experimenting with
thin-clients running M-Audio 192 sound card.
Working fine, but 2 Amps at 12 Volts is not easy
to achieve running 24/7.

 From many hours of simulation based on available
statistics, maps of average solar and wind
budgets (Geordieland, Benelux, Germany etc.)
I came to what follows.

~20 Watts, 24/7:
(Thin-Client, sound card, USB-WiFi, shadowing, losses etc.)
Batteries:>200 Ah
+ Solar panels:>100 Watts, ~40 deg. of inclination, S
+ Wind power:>100 Watts at 12 knots avg., ~20ft agl

Frustrating but not breaking down my B/S (°_°)
