Previously I wired a radio clock via a gertboard into my raspberry pi.

Since then, I figured out that I didn't need the gertboard there, and so now the clock is connected to my other "production" Pi directly onto the GPIO pins.

I've also put the C code I use to interface the radio into ntpd onto github. I needed to copy it from one Pi to the other, and doing it via github means you can download it too now. (yes, I know there are other implementations of MSF decoding around, but I wanted to write the code myself - this is supposed to be fun!)
