Very little FM, but as the EMF generated by lightning ranges from near
DC to gamma rays, you likely need to be a bit more specific.

Gamma rays...? Really?

I guess I should have read first. They speculate that electrons
traveling at near light speeds encounter nuclei and release their energy
as gamma ray photons. Very interesting. Seems this was discovered
relatively recently (~20 years ago).

Even so, the gamma rays are not a direct part of the radiation of the
lightning bolt, but rather are a result of the large EM field and are
relatively uncommon compared to lightning in general.

"Remarkably, we have found that any thunderstorm can produce gamma rays,
even those that appear to be so weak a meteorologist wouldn't look twice
at them," said Themis Chronis, who led the research at the University of
Alabama in Huntsville (UAH)

Yup. First discovered over 20 years ago.

I've seen more recent reports that suggest that the gamma-ray (and, I
think, X-ray) flux near a lighting stroke can be quite
strong... possibly enough to pose a health hazard to those nearby. It
was suggested that this could be another good reason for commercial
airplanes to avoid flying near thunderstorm cells. Although a
lightning stroke on an airplane does not generally present a shock
hazard to the passengers and crew (the metal body makes a good Faraday
cage) there might actually be enough gamma/X-radiation from the stroke
to give people onboard a hazardous dose.

The answer to the question "has anyone tried to find out" is yes, there
have been a couple of genuine properly conducted studies (Several in
fact) into how much power is present in a lightening bolt.. They did
not, far as I know, break it down into AM or FM (RF power is RF power,
how you modulate it is up to you) but they have measured it, Many times.

now, the implied question: How much power in a lightening bolt? I once,
long ago, knew the answer, Since I have read a couple of those studies,
or read of them,,, and I have also, long ago, forgotten the answer.
