Record I/Q samples using your favorite SDR at 437 MHz. There are GRC flowgraphs available to do the same. For example, to use the rtl-sdr recorder:
$ gnuradio-companion gr-sprite/examples/SpriteRecorder_RTL.grc
Then, decode Sprite transmissions with:
$ gnuradio-companion gr-sprite/examples/SpriteReceiver2.grc
To decode the samples you recorded, disable the rtl-sdr block and enable the File Source and Throttle.
