Thank you.
I made it with help of josh's
and your advice about frequency is helpful, too. :)

Good sleuthing, Josh.

Looking at the flow-graph, it seems like the modulation "bits" are
running at the same rate as the carrier frequency, which won't work--not
 even slightly.

Generally in AM/ASK, the modulation frequency is *much* lower than the
carrier frequency, my gut is that you'd need at least several cycles
 of carrier between each bit.
