Tim,

Those are 'vias' and they conduct the circuit path(s) from one side of the board to the other. Quite common on double sided boards.

Hi folks -
Between the torroids and the relays on the right side of the RF board are unsed holes right at the edge of the relays - can anyone tell me what they are for?
