AIUI, the wave / particle duality of the photon means that it has a
beginning
and an end, from the particle model.

The point of the duality model is that it appears to exist as both, or
may exist as something that exhibits the behaviour of both.

Therefore, the wave model must exhibit amplitude modulation to have such a
beginning and end.

Why must it?
It could have FM modulation or none at all. It could just start and end
(technically with a rectangular envelope but that would effectively be
no AM at all)
You do you claim it *must* have AM?

What is the waveshape of such amplitude modulation?

Planck's hv gives a fixed, particular energy for each photon; so how many
complete cycles
does the photon have within its amplitude envelope?

Can you define what you mean by "Amplitude Envelope" in this context?

For those who maintain that RF radiation from antennae is composed of
photons, where
does each photon end and the next one begin?

What experimental evidence is there that RF photons exist (it is easy to
show the existence
of continuous waves, of course)

These are pretty fundamental questions raised from the claim of photons and
perhaps the inability
of the photonists to answer them is indicative of their weak and uncertain
knoweldge of the subject area?

We don't know but that is the purpose of physics. We don't know what
causes gravity but we know it exists and we have experimental proof of
gravitation and a model down to a certain level that explains it and we
are banging the rocks together in CERN to get an answer but then that
answer will only reveal more questions.

Bear in mind that my physics degree leans more towards macro physics and
the physics of materials rather then sub atomics and quantum. I'm a
little rusty on this.
