[DSP-10] Initial testing

[Gérard Parat / F6FGZ]

Hello,

Power has been fired on the board ! No smoke signals are good news ;-)

I applied 13.8V because I had only this kind of power supply available. Of
course, I used a radiator mounted on U101. Most of the voltages are nominal
except those which are directly related to the supply voltage. BTW, some offset
are not nominal :

   * U105 pin 3 is 2.3 V instead of 3.5 V
   * U106 pin 3 is 3.7 V instead of 4.6 V
   * Q4 source is 1.38 V instead of 0.91 V
   * U8 pin 3 is 2.5 V instead of 2.8 V
   * U9 pin 3 is 3.4 V instead of 3.6 V

I suspect something wrong for U105/U106 but resistors values good.
