Radio Signals

 *  What is the signal that a radio-transmitter's antenna emits that a receiver's antenna absorbs?  It seems to me that a transmitter cannot produce a photon as long as a radio wave and that a radio wave cannot be singular, coherent or smooth, except perhaps at absolute zero temperature.

My conjecture:
 *  1)  During a radio-wave cycle, millions of electrons will emit photons that depart individually, intermittently and separately.  Those photons can’t assemble to make a single photon or even a coherent wave.
 *  2)  Each transmitter-antenna electron constantly undergoes thermal agitation at IR frequency, so no electron can move without interruption in response to its radio-frequency EMF, and no electron can emit a photon of radio-wave length given its collisions with thermally vibrating elements.
 *  3)  Thus, an electron of the transmitting antenna must emit numerous IR-length photons during a cycle, so the signal leaving the transmitting antenna must be showers of IR-length photons alternately carrying a net energy for accelerating electrons toward one or the other end of a receiving antenna.
 *  4)  During a phase of the radio-wave cycle, emitted photons must affect receiving antennae in a way expected of a growing or propagated magnetic field transverse to the transmitting antenna.  During the next phase, the action must be opposite.  Would that work be attributable to photon spin?  If so that might say something about photon spin.
 *  5)  It appears that the windings of a toroidal coil with rising EMF emits a signal mimicking that classically attributed to a growing magnetic field, but no magnetic field is found outside the toroid under continued EMF.  IR-size photons emitted from the windings could account for the rising-EMF signal with no continued-EMF magnetic field outside the toroid.  That is, the signal outside the toroid is a photon shower of specific spin, what I propose to be the radio signal.

 *  Perhaps my discomfort with existing descriptions of radio signals is due to my misunderstanding of the doctrine that an electron radiates when changing velocity, not when coasting in its inertial frame.  Can it emit just from receiving a changing EMF?

 *  I presume that Maxwell’s equations describe radio-signal emission and absorption phenomenologically.  Good for engineers,  But I obviously doubt that the actors are those usually imagined in applying Maxwell’s equations.  If I’m correct, then a revised accounting for radio transmission is due, one good for physicists.

 *  I would appreciate receiving addresses of internet sites providing evidence or arguments for or against my conjecture about radio signals.  Reply to David Regen  at  xms@bellsouth.net
