[/quote] There's more to this, if you'll keep digging. The electrojet is modulated by using a high frequency heater (a few MHZ) with the power modulated at the desired ELF/VLF frequency to heat the ionospheric electrons in the lower D-region. Figure 1a shows a sketch of the heater and heated region. The heated region is typically [b]at 75 km [/b](though this depends upon the carrier frequency) and [b]can be 30 km in diameter and a few km thick[/b]. Viewed from above (see Figure 1b) the heated region is a roughly circular patch. The smoothness of the heated region depends upon the antenna radiation pattern as well as D-region conditions. [b]The heating increases the electron-neutral collision rate which changes the conductivities.[/b] http://www.bariumblues.com/simulations_of_elf_radiation_gen.htm [/quote]

Simulations of ELF radiation generated by heating the high-latitude D- region
H.L. Rowland, Beam Physics Branch, Plasma Physics Division, Naval Research Laboratory, Washington, D.C.
By modulating the ambient current flowing in the ionosphere, e.g., the auroral electrojet, it is possible to generate extremely low frequency (ELF) and very low frequency (VLF) radiation. This ionospheric modification technique can provide such waves for probing both the Earth and the ionosphere- magnetosphere. The modification occurs in the lower D-region and can provide information about the ambient conditions in one of the least diagnosed regions of the ionosphere.
