Figured it out! :) It's all to do with DC balance and getting to UART to sync properly.
Here's a very helpful document: http://www.radiotronix.com/datasheets/an401.pdf

I am having trouble getting valid data from this receiver. I'm sending manchester encoded data, all looks good on a 'scope. However the DATA-OUT pin contains a massive amount of digital noise, before, after and superimposed on the data and the PIC uart cant make sense of it.
However I seem to be able to get valid clean data from the RSSI (signal strength) pin. If I hook that up the uart I get valid data, but at a range of only about 10 meters.
I'm using this module with a WRL-08945 (now retired (http://www.sparkfun.com/products/8945)
Anyone have any ideas? Cheers.
No public wish lists :(
