Steve Glass stevie.glass at gmail.comHi, I've just got a funcube myself and just this morning support for it made it into the GNURadio trunk. That should make using them lots easier. I am looking forward to seeing the DVB-T support get done because that will make using SDR *much* cheaper (23USD delivered!). The question you ask concerns the interface to the decoder... the _ff version has float inputs and outputs and the other takes bytes (actually two-bit symbols) inputs and float outputs. The latter needs a slicer before it but that is conceptually the right thing to do and so the _ff version is deprecated. Hope that helps.
