I've just looked at Vojtech's code, it seems reasonable *and* he's resampling from 8kHz up to 11.025kHz.
If I can get this working (and why not!) then I suggest we attempt to for a standard for the RSID codes similar to the SSTV VIS codes, maybe even storing the standard in this forum. This will really help when not using a 'standard' mode such as PSK31, 63 or RTTY.
