MF,

I'm just sharing some thoughts for our entertainment ;-)

Well, first tests have shown that the garden location is not much better 
on MF. But these tests were just over short times. Later in the garden i 
can remotely switch a bistable relay used as an antenna switch! So i can 
use loop antennas instead of the vertical, which may be an advantage 
depending on where the QRN and the wanted signal comes from... Not sure 
why there is not a higher SNR improvement. Either the home location is 
not as sub-optimal as expected or it is an receiver issue, which will be 
solved then.

Yesterday i've been there on the tree again ;-) doing some mechanical 
measurements. Today i mounted the 5V supply and the Raspi and its USB 
soundcard into a waterproof (IP66) box, which also has a waterproof 
feedthrough for the GHz-Yagi. Fortunately the small RP-SMA plug of the 
yagi also fits through the feedthrough since its outher diameter is just 
10 mm.

Enjoying work into the trees after such a grey winter!

Ah and unfortunately some blood from the tree dropped on the solar 
panel. But i helped the tree! See:

Does someone know how to clean the plastic surface of the solar module 
without making it dull? Sorry, it's a bit OT now ;-)

73, Stefan
