I wish to read the transmissions from a Hyundai car Fob, using a Picaxe.
I have done this successfully on a PC - using a TV Tuner dongle and SDR software, so I know what the data looks like. Obviously, SDR is outside the Picaxe's capabilities, so I'm looking for a generic module that can handle 433MHz FSK modulated data and has a simple 'data out' pin (or maybe even a serial interface).
I have found all manner of candidates, but they're either out-of-stock, shipped from far away lands, use SPI, or cost a fortune etc etc
Can anyone recommend one?
Supplementary question: Is there a standard for the pairs of frequencies used for FSK; does auto-tuning handle it, or would it need configuring?
