K3PGP VLF Experiments

The following is a digital recording of a natural radio emission (called a 'Whistler') associated with the Earth's atmosphere.

What is unusual about this recording is the Long Delayed Echo that occurs after the main event.

Listen closely after main event!


The following is a recording of some of the Omega navigational stations that operate in the vicinity of 8 to 12 Khz. This recording was made by plugging a loop antenna directly into an audio amplifier! The resulting signal was then shifted down in pitch so the signals are more easily heard. At least five stations can be identified by different operating frequencies.
