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
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.
Emergency receiver off.
Emergency receiver on.
5 – Activity and station 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)
