Got it! For anyone else, the IR was very dim when sending a signal.
I used http://arduino.cc/en/Tutorial/Fading to test an LED on pin3, then the same code to test the IR (i could see it clearly).
Then retried using one of the test libraries and realised I could just about see some flickers of output.
