5in my lab and were thus replaced with similar parts. Furthermore, the
6LED color was changed to ease visual identification:

12L2/L3 4.3 nH 4.7 nH 4.7 nH

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.
