One
of the main objectives of the South African Amateur Radio Development
Trust is to promote Amateur Radio and to support the South African Radio
League in its quest to introduce the science of Amateur Radio to the
young people of Africa and in particular to the young people of
South Africa.
GO INTO SPACE
LEARNERS AND
TEACHERS INVITED TO "FLY A FILE" ON ARISSAT-1
Learners and teachers are invited to
have their work flown in space in a new satellite project called ARISSat
which replaces the originally SuitSat 2 project which was a disused
spacesuit fitted with amateur radio equipment.
The ARISSat-1 Team wishes to include
a memory stick of files prepared by learners," explained Amateur Radio
on the International Space Station (ARISS)
International Chairman, Gaston Bertels, ON4WF. "This should be a .jpg or
a PDF of things the student has prepared." He gave such examples as a
paper or a study done on a STEM (science, technology, engineering, math)
topic, a drawing of spacecraft or a schematic, a journal kept on a STEM
topic, a story or news article about a STEM subject or a photo of the
class doing a hands-on STEM activity. Having the students' work be a
part of ARISSat-1 means the student is a part of the satellite project
and along for the spacewalk and deployment of ARISSat-1."
"The quantity of files and the size
of a file are unlimited, since memory sticks provide for a very large
amount of file space." Bertels said that files must be either in .jpg or
PDF format -- no Microsoft Word documents will be accepted. Files
can be in any language, as long as an English translation is also
included as a text file.
South African entries will be
coordinated by SA AMSAT and also placed on a local website. Entries
should reach
youth@sarl.org.za by 28 February 2010. Get more details

JUST LICENSED AND NO RIG YET? GET ON THE AIR WITH ECHOLINK
Talk for free!
So you have just received your new ZU, or ZR or ZS callsign and you
can’t wait to make amateur radio contacts …. You can’t because you have
no equipment as yet. Echolink can end your frustration within a
few minutes. After reading this article you could be accessing any of
the 2000 repeaters linked to the system and work some DX.
For licensed hams, EchoLink® software opens up new
possibilities for communicating around the world with other amateurs.
Your PC links you to any of thousands of other stations over the
Internet. There are more than 170,000 registered users in 158 nations
worldwide!
As a newcomer to amateur radio all you need is a PC, a microphone,
speakers and an Internet connection. A dial-up will work but a broadband
connection will deliver better quality.
How to get connected?
First you need to download the Echolink software. EchoLink®
software is offered free of charge to licensed Amateur Radio operators
worldwide, for Amateur Radio use only. Please note that you must
hold a valid Amateur Radio license in order to use EchoLink. After
installing the program, you must provide proof of license if you wish to
use it.
Jonathan Taylor, K1RFD, developed EchoLink in early 2002. In an
astonishingly short period of time, EchoLink has become one of the
dominant Amateur Radio VoIP systems. The free EchoLink software for
Windows can be downloaded at
www.echolink.org.
When you start the EchoLink software, your computer taps the Internet to
connect to an EchoLink server. Before you can make your first connection
to the network, your call sign must be verified. . This can take minutes
or hours, depending on the state of the system, but it helps reduce the
chances of non-hams entering the EchoLink network.
Once you’re validated (you only do this once), the rest is easy. The
EchoLink server acts like a telephone switchboard in cyberspace. It
maintains a directory of everyone who is connected at any moment. After
browsing the directory, you can request a connection between your
computer and that of another amateur.
Here’s where it becomes interesting. The amateur on the EchoLink receiving
end may be sitting in front of his computer with a headset and
microphone. Or he may have his computer connected to a base radio at his
station that is acting as an RF relay to a handheld transceiver or
mobile rig. Or the destination station may be part of a repeater system.
In any case, once the connection is established, anything you say will
wind up being heard in the other amateur’s headset, or transmitted over
the air.
At your end of the EchoLink connection, you may be the one wearing the
headset, or using a simplex connection to your base radio, or using a
repeater. When you connect to an individual station, the custom is to
call in the same fashion as you would during a traditional on-air
conversation: “ZS6ABC from ZU1XYZ.” Or if you are connecting to a
distant repeater system: “ZU1XYZ, Pretoria, South Africa, (You need to
hesitate about 2 seconds before speaking to compensate for the delay.)
The EchoLink servers also support conferencing where several
amateurs can converse in a roundtable fashion. There are even EchoLink
nets that meet within these conference areas on a scheduled basis.
EchoLink Setup
To run EchoLink you’ll need a PC with Windows 98/2000/XP and a
sound card. The software is easy to set up. A “wizard” function guides
you through each step.
If you want to enjoy EchoLink conversations while sitting at your
computer, you will need a microphone headset. These are commonly
available from computer shops. The microphone plug attaches to the
microphone input jack of your sound card and the headphone plug
typically attaches to the SPEAKER OUT jack. In addition to setting up
the EchoLink software, you may also need to adjust your sound card
VOLUME and RECORDING control settings in Windows.
If you are using a wireless router you may not be able to connect to
Echolink without changing some of the settings.
EchoLink requires that your router or
firewall allow inbound and outbound UDP to destination ports 5198 and
5199, and outbound TCP to port 5200. Source ports are dynamically
assigned. If you are using a home-network router, you will also
need to configure the router to "forward" UDP ports 5198 and 5199 to the
PC on which EchoLink is running.
The
EchoLink website,
www.echolink.org includes many
help files and a FAQ that will assist you in setting up.
