How exactly does the message signal get imparted on the carrier spectrum to reach its destination?

If you google "frequency modulation" and then "amplitude modulation" you will easily find this information.

basically with a transistor, the carrier signal fed across a transistor and the message signal applied to the base thus controlling the amplitude

of the carrier making it proportional to the message.

A similar method can be used to control the frequency of the carrier signal, the advantage is the carrier signal is always full strength

so you don't get noise problems with quite bits in music for example/.
