[DSP-10] microphonics !!! and noise pickup

[Luis Cupido]

Hi,

Finally I have my DSP10 running...
did a calibration and all looks very nice.
(still need to workout some mechanics for shielding etc...)

I noticed a great deal of microphony on the main PCB
I suspected of the oscillator cois (the most obvius place to look)
but is was not.
Switching to audio input the problem remains there... and
surprisingly I found that touching (with a plastic tool) C32
it makes an hell of a large sound....

Is is just a bad quality capacitor I'm using ?
Anybody else had the DSP10 with the same behaviour ?

Also I have quite a large pickup of digital noise, that is comming
from the DAC out connections to the RF board. Noise that seems
to exist in the EZKIT already... So looks that is nothing we can do
about this ...  Any idea.
