| Source at commit 79c9e3c1341fb475ea45b802ac1e5a9d4ce62aa8 created 7 years 3 months ago. By Werner Almesberger, atusb/Makefile (f, b): swap mask and copper layers for better visualization | |

| 4 | Some of the components specified in the schematics were not at hand |
| 5 | in my lab and were thus replaced with similar parts. Furthermore, the |
| 6 | LED color was changed to ease visual identification: |
| 7 | |
| 8 | Component Norminal Board 1 Board 2 |
| 9 | --------------- --------------- --------------- ------------------- |
| 10 | LED (D1) red red red-orange |
| 11 | C6/C7 0.82 pF 0.7 pF 0.9 pF |
| 12 | L2/L3 4.3 nH 4.7 nH 4.7 nH |
| 13 | |
| 14 | The resulting spectrum should be examined to determine which variant |
| 15 | performs better. Note that the discrete balun circuit shall be |
| 16 | replaced with an integrated balun later on. |
