| Abstract: | It is well known that non-linear interaction between whistler mode signals from a VLF transmitter and energetic electrons can successfully explain the generation of sideband spacings of 20 Hz or more. However, Park [J Geophys Res (USA), 86 (1981) 2286] has observed side band spacings of 2 Hz in the whistler mode signals transmitted by Siple station transmitter and received at the conjugate ground station of Roberval, Canada. It is shown that such small spacing need wave magnetic field amplitude of 1.5 pT, which is lower than threshold for non-linear amplification. The results indicate that linear amplification is able to explain such sideband spacings. |
