RF HARDWARE used to RECEIVE transmissions from PDM or Pod

@dan, @larsonlr, @seattlebrighton using rfcat, as described here:
NooElec rtl-sdr usb dongle from Amazon also receives: http://saw.amazon.com/gp/product/B00P2UOU72 SDR# on Windows tuned to 433.92MHz

SOFTWARE used with the above hardware to capture wireless signals

@dan, @larsonlr using RFCAT with these settings (PLEASE UPDATE): d.setFreq(433.91919e6) d.setMdmDRate(43210) d.setMdmChanBW(140000) d.setMdmDeviatn(10000) d.setMdmModulation(MOD_GFSK) d.setMdmSyncMode(SYNCM_CARRIER_16_of_16) d.setMdmSyncWord(0xCCCA) d.setEnableMdmManchester(False) d.setEnablePktCRC(False) d.setEnablePktDataWhitening(False) d.makePktlen(255) d.setPktPQT(1)

d.RFlisten

@seattlebrighton: SDR# (SdrSharp) on Windows: http://www.rtl-sdr.com/tag/sdrsharp.

SOFTWARE SETUP

Frequency to capture PDM and Pod wireless signals: 433.92 MHz Baud rate (data rate): 43210 Encryption: 2-FSK Encoding: though the specs say Manchester (signals encoded by a change in state, instead of low or high), better decodes are coming from NO Manchester Filter: ?

Example signal from PDM to request a Status response from Pod (containing Basal routine, IOB, etc)
