Replaying Wireless door-bell

I've captured the signal of my wireless door-bell with SDR#
You can see the picture here,IV9WfzD (as you see, there is no activity in the spectrum when I haven't pressed the button)
It's a very simple 3-transistor transmitter (like this: )
I want to replay this signal, so first I should know what modulation it uses.
Any ideas?

If that schematic is accurate, I don't think there's any modulation other than being turned on or off with the switch.
