CHAPTER 9 – FACSIMILE OPERATION
9.1 Overview
Weather Facsimile (WEFAX) is transmitted throughout the Short-Wave radio spectrum, pri-
marily to provide information to ships at sea. Typical stations you may find broadcast weath-
er 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 serv-
ices (see the frequency list below). Many of the photographs you see in your local newspa-
per 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 re-
ceiver, it can display reasonable definition. The AEA PAKRATT WITH FAX programs allow WE-
FAX 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.
