Hi, I've been having trouble finding 433MHz receivers which work. I have a project designed for a SIP style module, but at this point I'll settle for any package as long as the receiver works. I have tried 4-5 different receivers and they all have had one of two modes of operation: 1. So many random pulses on the digital output as to be unusable. 2. Good reception, except the _middle_ of the bits of a byte are not output= .. Only one module was in category 2, a RLP-434A from SparkFun. Funny thing is the module's analog signal strength output clearly showed all bits being received! I'm open to any recommendations and ideas. Thank you.
