...RBR-operation will lead to unusually intense HF blackouts for about the first half of the operation time, producing large scale disruptions to radio communication and navigation systems. While the neutral atmosphere changes are not particularly important, HF disruptions could be an important area for policy makers to consider,...

...doesn't sound all that different in character from the types of things being done with HAARP.
Moreover, I've long suspected that facilities like HAARP and ELF work in concert, using constructive and destructive interference to generate local effects from global signals.
What I mean is, maybe these facilities function as a system - like a radio telescope array - about which different researchers make different types of observations.
The purpose of this paper is to describe briefly the programme of active v.1.f. (3-30 kHz) experiments on the magnetosphere from Siple Station, Antarctica. Under investigation are new wave-particle interaction phenomena that are fundamental to an understanding of space plasmas. Included are wave growth, wave-wave interactions and wave-induced precipitation that are stimulated by v.1.f. signals from a ground transmitter. Possible applications of these experiments include measurements of the flux of radiation belt electrons, control of the ionosphere, control of the radiation belts and new methods of v.1.f. and u.1.f. communication.
Why have v.1.f. experiments in the magnetosphere attracted so much interest? The reasons stem from two remarkable properties of electromagnetic waves whose frequencies lie below the electron plasma and gyrofrequencies (generally called whistler-mode waves). First, their velocity is usually small, depending on the wave frequency and on the parameters of the medium. Second, the anisotropy of the medium tends to cause the wave energy to follow the direction of the Earth's field.
These properties make whistler-mode waves useful as detectors of the concentration of the thermal electrons in the magnetosphere. Field-aligned irregularities, or ducts, of ionization extending between the hemispheres further increase their value by trapping some of the wave energy. Trapping keeps the wave normal aligned on the average with the Earth's field. The trapped, or ducted, waves are more readily transmitted out of the magnetosphere, through the ionosphere so that they can be observed on the ground. The observed travel time versus frequency gives the path latitude and the equatorial electron density. Application of this technique led to the discovery of the plasmapause and to the first measurements of plasma convection within the magnetosphere.

I imagine some scientists use this system to influence the magnetosphere, to observe and model how the magnetosphere responds.

I'm sure he would have been proud...right.

By the way your link to the iop.org article (systems function) requires a paid subscription.
Perhaps you have another source?
Well, sort of yes, sort of no. A lot of these sort of things are not intended to alter the magnetosphere as much as they are experimenting with interacting with the magnetosphere in order to do something else.

So now a yes? What you said is irrelevent. Their intentions have nothing to do with it.
Tom your knowledge is known to us. You seem to disagree with everyone to prove your knowledge in Electronic Engineering. I have 2 years in DeVry and what you were taught is nothing compared to what "They" know.

A link to your source material if you please Sir. A layman analogy of your thoughts too.
US spots from Alaska to California (Caleefornia) and as I'm just told not all that far from Boston.
