8.97kHz noise levels

DK7FC has delayed further DX tests on 8.97kHz because of thunderstorms in Germany. Stefan comments that the noise levels appear to be rising as thunderstorm activity increases as we move towards summer. He is wondering if further VLF DX tests should be postponed until the autumn when the noise will lower again. You can check UK thunderstorm activity on the Nowcast website.

On the plus side, thunderstorms seem to generate Sporadic E. At least, that's my theory.

I agree. Somewhere I read that sprites firing upwards from thunder clouds may be the connection with E-layer sporadic ionisation.
