Topband: Inquiring minds want to know....

[Mike Waters]

In some ways it is much better. Remember *200 Meters and Down*?

I have two ELF receivers that feed the worldwide blitzortung.org network
and lightningmaps.org. It continues to amaze me how far that wideband QRN
propagates, even during daylight hours.

Most of those strokes' energy peaks around 20 kHz, but some extends
considerably higher. The receiver bandwidth goes up to over 200 kHz.

It's no wonder that so many hams are now on those VLF and ELF bands.
