This paper presents the first evidence of long-range detection (greater than 1000 km) of calibrated VLF signals resulting from the HF heating of the auroral electrojet, that is, signal detection at a point of direct 'line of sight' of the heated patch of ionosphere. The 'radial' as well as the'azimuthal' magnetic component of the signals are recorded; from their ratio, the waveguide mode polarization is obtained. Observed absolute magnetic field strengths and waveguide polarizations are found to be in line with the predictions of simple waveguide models. 17 refs.
