FOR VLF/LW/SW Page 1
it reaches up to 10 to 11 years, solar activity gets high to very high, and weird
occurances even with FM and TV DXing gets extremely rare permitting stations from over 1000 miles away.
The propagation or LW/MW gets to moderate but with alot of lightning storm development it gets difficult. Most storms happen every 11 years and the polarity could could change. But for mostly LW its the groundwave propagation we have to
be aware of . As for shortwave the F1 and F2 layer gets affected by solar activity
and causes disruptions in communications on the HAM and SWL broadcast bands.
If you don't have a computer available, you can tune into these frequencies
2.500 MHz or 2500 kHz for 120 meter openings & 160 meter openings
5.000 MHz or 5000 kHz for 60 meter openings & 80 meter openings
10.000 MHz or 10000 kHz for 31 meters openings & 30 meter openings
15.000 MHz or 15000 kHz for 19, 22 meter openings & 20 meter openings
20.000 MHz or 20000 kHz for 16 meter bands & 15 meter openings and 10
Beacons are a great resource for band openings, there are some in the 20 meter
and 15, and 10 meter regions.
BUT you have to be closer to the ocean to receive it well, like here in Virginia Beach, or New York,
Maryland, or Connecticut or some where like the in the East Coast regions. Also you must listen
between 2300 to 0700 UTC at the East Coast and for the Pacific DXers 0700 UTC to 1200 UTC
before sunrise which would make LW Pacific DX difficult for some but advanced users of radio. This
diagram shows that its 1400 EST here and its midnight in the Asiatic areas. If the the path of darkness
is between North America and Europe, this is the best time for East coast DXer's to tune to LW broadcast signals. We will be showing you an example soon of it when it becomes available. Longwave has great DX opportunities, it also makes sure that your clock is set right with WWVB, DCF77, and others even 162 radio frances subcarrier.
ABOUT VLF RADIO RECEPTION
For VLF regions where most lightning is, this is were most Natural Radio emissions happen, its also a
detector for to listen to strange noises from the magnetosphere. The VLF Natural radio region covers
a wide 1 to 10 kHz and most receiver, such as amplifiers cover 300 Hz to 20 kHz like your sound
card for example. The main receiver is a fabricated active broadband circuit connected to a micro
phone preamp circuit that runs on ethier 9 or 12 volts of DC current. The good thing is that you could
probably use a solar panel of some sort to power up the Natural radio receiver circuit, while charging
the 9 volt battery for nighttime, or simply just apply a alkaline 9 Volt Battery to the circuit itself.
CHORUS: Chorus is caused Auroras and geomagnetic storms in the ionospheric region, you will
hear bird like sounds that are scattering all over the place. This happens during major high solar
activity events.
WHISTLERS: Whistlers occur when lightning occurs from another region on the planet and causes
a desending tone that curves though the magnetic field lines of the magnetosphere. Whistlers occur even also in major and moderate geomagnetic storm events. They only can be received away from good locations away from power lines, and equipment has to be properly tuned between a broad spectrum of 1 to 10 kHz.
SPHERICS : Spherics can be heard on a broad range of frequencies from 1 Hz to Light regions, that
means mainly your LW or AM portable can be a good lightning detector. Spherics are always heard
on VLF no matter what cause lightning static discharages can be heard across the country and even
the world.
