Sure, so I'll try to explain my point here a little better. Say we
have a vertical receiving antenna, and two MW transmitters that
transmit waves of the same frequency, but perfectly out of phase
(relatively shifted by 1/2 the wavelength) at the location of the
antenna. The waves transfer energy inducing electrons in the antenna
to accelerate. According to the theory, this energy transfer (and
thus the acceleration) is quantized, hence "photons". Now, any
random electron will from time to time absorb a photon that either
accelerates it in the "up" direction, or in the "down" direction,
and since we have two sources with cancelling phases, for any finite
(and sufficiently large) interval of time, the electron will absorb
approximately as many "up" as "down" photons.

Pah! That would mean you got increased random noise, which you do NOT
get. The environment would be 'hotter'.

Yes, and this is exactly what I believe will happen. The energy absorbtion
should lead to a small rise in the temperature of the antenna, even though
no information will be detected.

No, because the field strength is demonstrably zero.
It can be measured.

The electron will thus
exhibit a random walk, and no signal will be detected. This,
however, does not mean that the *photons* interfere with eachother.

Its by far the simplest explanation. The em field is zero and no
photons are detected.

Interference, as in
the double slit experiment, would mean that photons from the two
different sources cancelled each other (or more precisely, they
would be more likely to show up at another location), thus there
would be no energy absorbtion by the electron whatsoever.

Which is precisely the effect of radio waves.
Think about it.

In the radio wave case, with two different transmitters, you should be able
to pick up one of the signals with a directional antenna. This is
impossible in the double slit experiment (with equipment analogous to a
directional antenna, say a focusing lens), since seen from the points of
destructive interference, both slits look dark. There is simply no energy
reaching these points.

That would be an interesting example to do.

However you will then see a signal simply because there is NOT a path
from one slit to the detector which cannot see the other slit. This
would be equally true whether you used two transmitters (lasers, stable,
very) or one transmitter and reflected the radio wave (or light) to the
same location as the second slit. You certainly cannot differentiate
between self-photon interference and separate-photon interference by
this method.

In essence you CAN tell which slit the light came from because your
directional antenna detects the direction (momentum).

This post is worth absolutely nothing and is probably fallacious.
