Problem with an aurel receiver

Hi,

i want to create my own automation box. So i bought a first rf433 receiver on ebay (xy-mk-5v). I soldered an antenna on it. then I connected the receiver to my raspberry. Everything is ok except the range. i have to be near my receiver to receive code. (code send by a door sensor by DIO) So i decided to change my receiver and i took an aurel RX-4M50RR30SF. With this one, i'm not receiving code from sensor. I use an external power which deliver 5.02V. If i use RFSniffer to test if i get a signal, that's work! https://github.com/ninjablocks/433Utils/tree/master/RPi_utils I use this code http://domotique.idleman.fr/data/chaconPI/radioReception.zip The first receiver has OOK modulation The second AM modulation Where is the problem? thank you for helping me.
