Hi Stefan, MF !

A small introduction to beaconing by MultiPSK (for any mode):

MultiPSK calls its long macros "sequences". There can be 1 to 24 
sequences, each stored in a file named "Fxx.SER", where xx is the 
sequence number ranging from 1 to 24. My example file is called 
"F1.SER", it is a replacement for the original file.

Install MultiPSK, then first replace old "F1.SER" file in the programs 
directory by the supplied one. Start MultiPSK and go to "configuration 
screen" (=first screen at startup), set your soundcard settings for 
"input" and "output" and define your PTT-COMport at "serial port". At 
the left middle of the configuration screen there is a panel for "beacon 
mode (all modes)". Set both sequence numbers to "1". Set "pause" to a 
suitable time between two consecutive transmissions. Set "duration" to 
several hours, if you want to stay in beacon-mode all night long. (meant 
is NOT the duration of the single transmission!!!)
When setting "prior serial number", there will be a "Message nnn" at the 
start of each beacon transmission, where "nnn" is incremented 
automatically starting at "1".

Leave configuration screen by a click on "rx/tx screen".
Now you are in the main window.

Select "AMTOR-FEC-Navtex" in the mode-selection-panel at the upper 
right. (and please select Shift = 170 at the panel just above the middle 
of the waterfall.)

Next click on the item "configuration" in the main menu line on top of 
the screen. Select/click on "personal Data" and set your call, name, 
city etc.
Your texts for <MY CALL>, <MY NAME>, <MY QTH>, <MY LOCATOR>, <ANTENNA>, 
<RIG>, <WEB ADRESS> are used by the F1.SER sequence.
Please enter your personal data. After completion click on "save" and 
you are back in the main window.

That's all for configuration. (the audio frequency used -1500 Hertz- is 
defined in the F1.SER file already, = need not be set)

Now we can test it for a first time :

Start a first single beacon transmit by pressing the "F1" function key 
on the keyboard, or by clicking on "Call 1 F1" at the very left just 
below the waterfall. You can watch the echo of the transmitted 
characters at the Tx-area.

Verify that the text of the message is ok. ("Message nnn" is not shown 
yet, it is inserted later at beaconing)

Now we are ready to start beaconing. There is a "Beacon" button situated 
just below the "help" item of the main menu. You start the beacon-mode 
by clicking on this "Beacon" button (click again to stop). A big yellow 
band with "Beacon : AMTOR transmission" just below the weaterfall 
verifies that the beacon-mode is on.

That's it.

Beaconing-mode will stop automatically after "duration" time is over, or 
at a click on the "beacon" button.

(There is a help function on the right mouse button for most items used 
here, but you are warned : the help function of MultiPSK is extensive 
and detailled, you could end up reading a manual)

Give it a try, maybe it's worth it.
