FACSIMILE OPERATION
9.1 Overview
Weather Facsimile (WEFAX) is transmitted throughout the Short-Wave
radio spectrum, primarily to provide information to ships at sea.
Typical stations you may find broadcast weather maps showing current
as well as predicted weather conditions and satellite photographs
showing the cloud cover over a large area.
Not only weather information is transmitted, but also news photographs
from the wire services (see the frequency list below). Many of the
photographs you see in your local newspaper every night are
distributed via facsimile and some can be copied on your printer.
Although a dot matrix printer does not have the resolution of an
expensive facsimile receiver, it can display reasonable definition.
The AEA PAKRATT WITH FAX programs allow WEFAX to be displayed on the
screen of your computer. Many people prefer this to printing.
9.2 Finding FAX Frequencies
The following is a list of frequencies that seem to broadcast on a
regular schedule. A few of these stations transmit 24-hours/day. We
suggest you try the weather FAX frequencies listed below while you are
becoming familiar with the commands. After you print a few pages, and
have become accustomed to the sound of facsimile you will be able to
tune the bands in search of other frequencies where perhaps different
kinds of pictures may be found.
