How-To: Use the control-panel


The control panel includes a relatively large number of functions, including those that are unlikely to be found in a radio station, such as the position (Lat / Lon) input fields, a compass, and the heading and speed display.
But one after anonther:

1 – Radio room clock
       with green and red sectors for the silence periode

2 – Band selector switch


       Switch for selection of the frequency band. Wider bands can
       be switched by multiple clicking, e.g. 4 ranges in 8 MHz
       Band. Frequency selection in the main receiver depends on the
selected Band.

3 – Server control display


       Display for send / receive channel (WebSocket connection) and
       Connection to the database for regular broadcasts of Coast-
       stations. In the top line must always be “Server connected”, in the
       bottom line “Ready”, otherwise there is an error. In the case of an
       Error sometimes it helps to “reload” the page.

4 – Emergency receiver (500 kHz)
       The auxiliary or emergency receiver only has a frequency of 500 kHz
       and a volume control. With it, the 500 kHz can be observed in parallel if           the main receiver has just been set to a different frequency. The receiver         has its own display for the representation of the received characters.       
       This becomes visible when you click the chat button a second time. 
       Every further click changes the display between receiver #1 and #2.

5 – Activity and station display

Activity Display

       This display gives you an overview of the activity in the various bands.   
       Normal stations will be displayed yellow, stations with a running loop     
       green. In the small window at the bottom left of the display, the
       callsign of the sending station is displayed.
       If the main receiver is switched on, the activity display can be used to set
       the frequency by means of a mouse click on the frequency or by use of 
       the mouse wheel. The selected frequency is marked by the red needle.

6 – Display switch (chat, chart etc.)


        With the chat button you can get to the text window for entering and
        output in Morsechat. The digital nautical chart is displayed via the Chart
        button and the telegram form is called up via TTx. The transmitter     
        sidetone is switched on and off with the MUTE button. With the OFF     
        button you can leave the radio station and return to the calling page.
        With Docu there will be another register opened in the web browser     
        and the page ‘Who is online?’ is displayed. The NAV button indicates
        that the autopilot is on (Default setting at startup). When the NAV
        button is turned off, any position can be entered via the input fields for
        the position. The previously selected route is then exited. If the NAV
        button is then switched on again, the ship moves directly to the next
        position of the selected route. Directly means, directly over land too!
        The other switches are not yet assigned.

7 – Oscilloscope 


         Provided that the transmitter is switched on and mode is set
         to ‘Key’, an oscilloscope is available via the scope button so that the     
         shape of the signals InSig and OutSig can be watched. To the right of
         the scope button there is a field for the Selection of the signals InSig
         and OutSig. The threshold value can be set with the slider on the far
         There is a separate page in this for operation Documentation (Link …).

8 – Input fields for the position (Lat / Lon)
         By entering new data for the position, the ship position can be changed           directly in the radio station. The values must be entered with decimal               places. The course can be adjusted with the steering compass. The
         ships speed cannot be changed here.

9 – Steering compass
         Steering compass for displaying and changing the course. (change with           the mouse wheel when the mouse pointer is on the compass or
         directly in the input field)
