add hardware layout for a proof of concept receiver

[armin-bauer]

the receiver should be able to detect jupiter bursts (http://en.wikipedia.org/wiki/Magnetosphere_of_Jupiter)

The detector should be sensitive to frequencies between 18 and 28 MHz. Those are commonly not used in shortwave-transmissions. The optimum is thought to be at just above 21MHz because

• at 18MHz there's a lot of man-made radiotransmissions
• at > 24MHz the intensity of the radiowaves drops

The goal if to detect jupiter bursts and have some working hardware to measure the magnetospheres of SUN and JUPITER.
