4Some of the components specified in the schematics were not at hand
5in my lab and were thus replaced with similar parts. Furthermore, the
6LED color was changed to ease visual identification:

14The resulting spectrum should be examined to determine which variant
15performs better. Note that the discrete balun circuit shall be
16replaced with an integrated balun later on.
