Gain was way too low

• The header H1 was not shorted on the board.
• This reduced the gain of first stage to only 2, while it wsmeant to be 101!
• I just opened the box and put back in jumper on this header.
• The gain slider for AD602 is at -1 dB, 1 dB below the unstability point.
• Earlier the slider was maxed out to 30dB, so we didn't know if we are close to optimum supression.
• Changes have been updated in the schematic.
