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!

See: https://dl.dropboxusercontent.com/u/19882028/MF/20150214_154054.jpg 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

Hello Luis,

Since when do you have a grabber? :-)
Is it from the remote site using the GHz link?
I'm preparing the same here. There is good progress! Maybe i can use it in a 
few days :-)

My normal ("urban") MF grabber is of course running for Lu
