Radio amateur Dr David Morgan 2W0CXV has published an article about the possibility of the generation of Very Low Frequency (VLF) emissions in the range 1 to 10 kHz by an ionised meteor trail. He used a FUNcube Dongle SDR as part of the equipment for his experiments.

This article reviews the interesting, but not widely known, possibility that an ionised meteor trail can generate Very Low Frequency (VLF) emissions in the range 1 to 10 kHz. The work of several academic authors is referenced to describe the phenomenon and explore the physical mechanism that may be involved.

In this article he discusses the possibility of amateur radio astronomers being able to detect meteor radar echoes and simultaneous Very Low Frequency (VLF) signals in an attempt to establish a causal connection.

Measuring RF Noise Sources with a SDRDavid Morgan 2W0CXV has released several papers covering the use of the RTL-SDR Dongle in radio astronomy.

In 2011 David described the equipment configuration and software involved in setting to work a small 3m diameter amateur radio telescope using the FUNcube Dongle Pro software defined radio receiver.

At the end of 2014 he published a paper dealing with the setting up and use of a RTL-SDR dongle to receive meteor pings from the Graves Radar on 143.050 MHz.

He has now released two new papers covering the measurement of signal strength and  RF noise sources with the RTL-SDR.
