In this instance I wasn't going for lightning specifically.  Generally 
when lightning approaches I unlpug my radio observatory but in this case 
I was in town when the storm happened and I was lucky that my arrays 
were not hit.  So this particular recording is kind of an anomaly but is 
interesting for comparing lightning strength with solar burst strength.  
The solar burst has more energy that the lightning in this case.  I 
think this is a rare recording.

I monitor the Sun (and Jupiter) at multiple frequencies from 50 MHz to 
Message: 18.
Subject: 7 MHz with different radios and antennae cut per specific frequency. 
   22.2 MHz and 22.7 MHz are useful for Jupiter as well as the Sun.  The 
500 MHz separation in frequency between right and left channels gives a 
spatiality to the reception especially when listening with headphones 
because solar bursts generally pass from high to low frequency so will 
hit 22.7 MHz then a split second later hit 22.2 MHz.

The recording is stereo based so as to accomodate the bilateral body 
limitation of having two ears;  two bio-ports into the central nervous 

Feel free to ask further if you want more details.
