[Swlug] Morse code project

[Rhys Sage]

At the moment I'm building a QRP Pixie shortwave transceiver. It'll produce likely an analogue audio output. I'll need to feed that into a Raspberry Pi. Do I need to use a digital to analogue converter and has anybody any pointers? I realise I'm jumping around on various projects. It's how I do things. 

Transmission is blindingly simple - I'd just put an optically-isolated DC relay on the GPIO and use that to close the key on the transmitter. Even the Python code for that is straightforward. Reception and turning the input signal into something recognisable as Morse is a lot harder.
