Article on AM/OOK RF reception and transmission

I found this very interesting article on one way in which to listen to and then interpret the RF signals which are generated by wireless doorbells and, most interestingly from my perspective, remote sockets.  It's a good read, and goes a long way in helping me send RF signals to the "Delta" remote sockets I have which don't conform the the Homeeasy/ Byron protocols which the rest of my sockets understand.
