THE VLF PAGE
Very long, long, long, long wave reception.

New to listening way down the spectrum between DC and 22kHz, I'm finding this aspect of the hobby fascinating. Sferics, tweeks, whistlers... All these strange noises come from lightening strikes around the world. Using the program, Spectrum Lab, you connect your aerial straight to the mic socket on your computer's soundcard. Sounds crazy? Not at all. Take a look at the pic below.

SCREEN SHOT OF MONITORING 9kHz

WARNING! READ THIS BEFORE GOING ANY FURTHER!

Voltages high enough to kill can be present on long wire aerials. My 150 foot wire aerial charges up with enough static to flash across the vanes of the variable capacitor in my matching unit. Rain is enough to do this, let alone a nearby thunder storm. And as for the input on your soundcard... Flash, bang - no more soundcard. Or mother board if you're unlucky! Start off with a few metres of wire slung out of the shack window rather than a bloody great length of wire up at 100 feet.

Today, Tues 4th June, I've been monitoring 9kHz since 7am. The sferics, from the word atmospherics, have been on the increase since lunchtime. Now the time is almost 6pm and the waterfall display, and the loudspeakers, are going crazy. Topband is wiped out with crashes, and I reckon that we're in for an interesting night on the VLF band. If I'm lucky, I'll hear some tweeks or even some whistlers. More about that another time.

Apart from the above stations, I've also heard a washing machine, an electric drill, what sounds like a vacuum cleaner and, last but not least, a vibrator. What a fascinating band!
