ASK Demodulation using gnuradio and usrp

GNU Radio
#1

Hi,
I am reading data using usrp at 916MHz band. The data uses ASK
(amplitude
shift keying) modulation. I am trying to demodulate the data to binary
stream, but usrp/am_rcv.py does not seem to serve my purpose. What
should I
do for ask demodulation? Please advise.

Thanks,
Hossen

Someone has done a GRC flowgraph for ASK for Keeloq hacking:
