The Auroral Kilometric Radiation (AKR) was investigated on measurements in the POLRAD experiment on the INTERBALL-2 satellite. It was revealed ”lowfrequency” radiation with specific features in a spectrum on a polar edge of the auroral region. We have obtained that a series of narrow-band splashes are observed at frequencies between 35 and 70 kHz with the period modulation some tens seconds and bow-shaped envelope. Possible interpretation of emission generation with a specific spectrum is discussed. We suppose that increase of intensity at small frequencies is interpreted as crossing by the satellite of the source region and observation of waveguide modes within it.
