First off two receivers were used. The first receiver had a high end frequency cutoff of 40 hz. give or take. As you can see in the following two charts quite a number of the resonances are seen using the soundcard of the laptop.

Having the ability to see a number of Srs is nice but my focus was to be on the first two. Please keep in mind the next chart was created by using the soundcard approach but Spectrogram was optimized to reveal the first two resonances with clarity.

Now let's get on with the Alpha test. The Alpha recordings were created using a Dataq 154 and a receiver with a highend cutoff frequency of 20 hz. I should say it starts rolling off at 20 hz. In this first chart you will see me tweaking the receiver in the beginning of the chart. So can Alpha see Schumann?

This next chart is in order time wise after the first. Wind noise begins to be a problem and if you look at the Avg line you will notice average noise begin to increase more towards the end of the chart. This is due to it almost being high noon and old Sol was high in the sky. You can also notice signal/signals between the third and fourth resonance. I do not know if this is SR or wind related.

On to the third chart which is also in order time wise. It starts precisely at high noon and the noise and wind increase is evident.

This adventure would not be complete without a few photos of Schumann /Alpha Camp One. Frankencoil is beneath the blanket to try cutting wind noise. It did not help much.

SR and Alpha Camp One is in a shallow wash.

Alpha in the trunk.

This next chart is a product of using Cool Edit 2000 to de-noise a wave file of the first two resonances before processing.
