I guess he is picturing the quanta as a pulse of a wave which it
*isn't*.

Consider a quiet band, and you receive a single dit, the letter E in Morse
Code.

Before there would have been no signal and neither after the dit.

So, if your RF photons do not have a beginning and an end, as they must do
as pulsed phenomenon, how come there is only signal during the duration of
the dit?
