ok, The board works ok, but when I hook my homemade radio up to the same power supply, My radio receives white noise.

When I use the radio separately, it works perfectly.

I have targeted most of the problem to the clock. The reason why I think that is it is because when reset is high, the interference stops.

My clock circuit onboard now consists of a 3.6864 Mhz crystal and two 33pF capacitors connected from each end of the crystal to ground. (your typical crystal setup).

I'm thinking of adding a resistor across the crystal to suppress the noise, or adding a resistor across each capacitor.

what would you suggest?

because I think the crystal is the source of the noise.
