Default Planck's Constant?

Do radio waves occur in photons, as some would claim, or
are photons just a facet of being generated from subatomic
actions?


It's more a matter of observation than of generation. Try to think
simply of electromagnetic energy (one of the 4 basic forces). If you look
for wave-like behaviour, then that's what you'll see. Ditto for
particles. It's called wave-particle duality. I don't know if there's any
easy way to demonstrate particle behaviour at RF energy levels, which is
why we tend to describe RF energy in terms of wavelength or frequency.
Similarly, it's not easy to observe or measure wave-like behaviour with
X-rays or gamma rays, so they are normally described in terms of their
photon energy in MeV, GeV, etc.


For example, assuming that the Big Bang is true, in the short
time afterwards, there were no subatomic particles but there
would seem to have been a massive outward flux of energy.

If radio waves are generated as photons, are they generated
in phase, and how much energy is associated with each photon?


Again, you need to think in terms of observation rather than generation.
The energy of each photon is given by the simple formula
E = hf, where h is Planck's constant and f is frequency.
