The NCDXF/IARU Beacons
The NCDXF/IARU International Beacon Network is a system of 18 CW beacons
located around the world which transmit in sequence with varying power
levels 24 hours a day. They use identical radios, antennas, and GPS receivers
to synchronize their transmissions. The beacons share specific frequencies
on five amateur bands: 20, 17, 15, 12, and 10 meters. Each beacon transmits
in a predefined, ten-second window, repeating every three minutes.

PocketBeacon
After aquiring a PalmPilot, I started looking for applications to explore
the capabilities of the PalmPilot and this seemed like a perfect match.
Similar applications that run on DOS/Windows can be found at the above
website.
NOTICE: Because of math library limitations, PocketBeacon only runs
on version 2.0 ROMS. In addition, you must have MathLib installed on your
PalmPilot. MathLib is included in this distribution if you do not already
have it. For further info on MathLib go to:
http://www.radiks.net/~rhuebner/mathlib.html
PocketBeacon displays a real-time list of the last, current and next
beacon scheduled to transmit on the selected band and updates this list
every ten seconds as the transmitting station changes. Information displayed
for each station includes the callsign, short path distance in Kilometers,
and short path beam heading.
Updates
Updates will be made available as beacons change or are added. New feature
suggestions are welcome as well as bug reports. Send all comments to:
