What is SKYWARN
SKYWARN® is a national network of volunteer
severe weather spotters. The spotters are
trained by local National Weather Service
Forecast Offices on how to spot severe
thunderstorms, tornadoes, hail and flooding.
In some parts of the country, spotters also
report snowfall and ice accumulation.
Two-thirds of the NWS volunteers are licensed
amateur radio operators. Amateur radio plays
a big role in the SKYWARN® program. During
severe weather, amateur radio volunteers
man a radio station at the NWS office. They
talk to spotters in the particular area that a
storm is hitting and request information
needed by the forecasters such as hail size or
rainfall accumulation.
Large storms such as hurricanes can knock
out phone service. Skywarn® Amateur radio
volunteers help the NWS when there are
communications outages so that they can
continue to receive weather reports and feed
warnings and other critical information out to
communities.

EchoLink
EchoLink is a computer-
based Amateur Radio
system distributed free of
charge that allows radio
amateurs to communicate with other amateur radio
operators using Voice over IP (VoIP) technology on
the Internet. It was designed by Jonathan Taylor, a
radio amateur with call sign K1RFD. EchoLink is
available for Microsoft Windows, Android, and iOS.
You will need to provide proof you are Licensed
Amateur Radio Operator before access to EchoLink
is granted. This is to ensure that only licensed
Amateurs have access to the system, and to ensure
that each user is using a valid callsign that he or she
is authorized to use. The software is easy to install
and use.
