A discrete VLF frequency of 3 kHz was successfully radiated by a modulated electron beam on a rocket launched into an active aurora. Instrumentation on this flight included a programable electron accelerator on the aft section with various particle and field detectors on the aft section as well as the ejected forward payload. Four-kV electrons are current modulated at a 3-kHz rate between Imin = 0 or 10 mA and Imax 80 mA. The forward payload, which was ejected at about 10 m/s, included a pair of spherical double probes separated by 2.75 m and connected to a VLF receiver operating between 30 Hz and 18 kHz. Both this broadband receiver output as well as various narrow band channel outputs were directly telemetered to ground. Post flight spectrum analysis of the broadband VLF data clearly indicates that signals during the 3-kHz accelerator modulation periods were propagated to the forward payload.
