3.5 Weather Chart Reception

The FMD55 can receive and print out weather charts,

(facsimile transmissions in F1C) if they are transmitted

according to normal standards.

Before printing out a chart, make sure that that you have a

reasonably disturbance free reception. For your assistance,

apart of the LCD display is reserved to project the incoming

signal. The signal is visible within the 855 to 1920 Hz band.

Weather transmissions consist of a signal spectrum in shades

of white, grey and black. With a reasonably clear reception,

you should the following picture on the display:

As a rule it is seldom that you have a perfectly clear

reception, therefore interference will be visible on the

screen as well as the incoming signal. Adjust the receiver

that you hear the best possible reception of a chart signal.

To do this select the FSK mode. The signal can be found

somewhere in a frequency tone range of 1000 to 2000 Hz.

Press the <DECODE> key until FAX appears on the display. A

small menu will now appear on the display allowing you to

adapt the method of decoding to the signal.

-PRINT: NORMAL/ INVERS allocates correctly, the

transmitted signals into BLACK and WHITE

Basic set-up is NORMAL.

The integrated printer cannot pick out the grey values, but

this is unimportant as weather charts consist mainly of black

and white information.
