Information

When CB/WX is on WX position Weather Receiver
is activated.

For a list of weather frequencies
see specification in the
Frequency Ranges section on
page 34.

If you wish to receive a listing of
NOAA ‘Weather Radio
Transmitter locations, contact
your nearest National Weather. 

Service Office, or write to:
National Weather Service
(Attn: W/OM11) NOAA
Silver Springs, MD 20910.

For ideal weather reception use
a dual band antenna (center
load/baseload).

What You Should Know About  Weather

If threatening weather is nearby, the National
Weather Service may broadcast a 10 second alert
tone. This tone will be heard through the CB, even
if the CB/WX Switch is in the CB mode or the unit
is turned off. 

This enables you to monitor CB frequencies and
still be warned by the National Weather Service
Emergency Alert. When you hear the alert, place
the CB/WX switch in the WX position. You will
then be able to hear the Weather Warning
Broadcast.

You can completely disable the Emergency
Weather Alert feature by turning the Weather
Channel Selector to the     position.

Your 29 WX NW BT has a special auto squelch cir-
cuit for weather transmission which disables your
squelch control.

If you are using the CB mode, remember to
change the CB/WX Switch from CB to WX every so
often to make sure you are continually tuned to
the clearest/closest weather band channel in case
an alert is broadcast.

What is Weather Radio

NOAA Weather Radio (NWR) is a service of the
National Oceanic and Atmospheric Administration
(NOAA), of the U.S. Department of Commerce.  380
NWR stations are in operation by the U.S.
Government in addition to several NWR stations
that are maintained by private interest groups. The
capability is to supplement warnings by sirens and
by commercial radio and television. The 7 National
Weather Channels provide full coverage to keep
you informed of weather conditions, 24 hours a
day, 7 days a week.
