Hi Matthew, Roman Black has a done a good writeup of cheap RF modules and the best was = to use them: http://www.romanblack.com/RF/cheapRFmodules.htm Cheerful regards, Bob ________________________________________ From: piclist-bounces@mit.edu on behalf of Matthe= w Miller Sent: Thursday, January 19, 2017 3:13 PM To: Microcontroller discussion list - Public. Subject: [EE] Recommendations for 433MHz receivers? 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.
