I have manualy copied this PCB layout from a printed version.
I think this one is better than that presented in the project page.

Good luck !

Can it be received as far away as across the street?
Does its frequency change if anything gets near it and when its battery voltage runs down?
Does it sound like there are no treble audio frequencies when it is heard on an FM radio?
