Hi Uwe,

Thanks for the test. I will try... But the QRN is much higher now. Maybe it is helpful to repeat the test tomorrow starting 9 UT? If you can and like...

More news: I managed to run 2 soundcards on a Raspberry Pi 2B. They are streaming simultaneously. I will install this on the tree in the forest. So one is stereo and for the 2 MF loops, the other one will be mono and for VLF and will run on request or when there is plenty of energy reserve. I will try to install an actice E field antenna there. Experiments in the past have been very promising! So maybe i can get one or two dB SNR improvement...? It will be interesting to compare both locations...
