DC7BJ. NCDXF  beacon monitoring

Last update 08/26/2005

The ´Northern California DX Foundation´ NCDXF operates worldwide a sw beacon system. Maximum 18 beacons send on 5 bands (14.100 MHz, 18.110 MHz, 21.150 MHz, 24.930 MHz And 28.200 MHz). These beacons send in every band within 3 minutes some time for 10 seconds. After the call sign 4 dashs are sent. The first dash has 100 W, the second dash 10 W, the third dash 1 W, the fourth dash 0.1 W. The observer can get in 3 minutes cognitions about the DX conditions world wide.Further information you can find at the site of the NCDXF, with the actually beacon data sheets. There are links to computer programs which makes easier watching. I also have compiled a DOS software (Running well under Windows 3.xx, Win98/Me): BJBEACON . But take notice of the collection of new Windows programs on the site of the NCDXF.

HAARP also watches the NCDXF beacons : High Frequency Active Auroral Research Program.

DC7BJ. NCDXF Baken Beobachtung

Letzte Bearbeitung 26.08.2005

(Die ´Northern California DX Foundation´ NCDXF betreibt weltweit ein KW-Baken-System. Maximal 18 Baken senden auf 5 Baendern (14.100 MHz, 18.110 MHz, 21.150 MHz, 24.930 MHz and 28.200 MHz). In jedem Band senden diese Baken innerhalb von 3 Minuten einmal fuer 10 Sekunden. Nach dem Rufzeichen werden 4 Striche gesendet. Der erste Strich hat 100 W, der zweite Strich 10 W, der dritte Strich 1 W, der vierte Strich 0.1 W. Der Beobachter kann in 3 Minuten Erkenntnisse ueber die DX-Ausbreitung erhalten.

Weitere Informationen koennen den Seiten der NCDXF entnommen werden, mit den aktuellen Baken-Daten. Dort sind auch Computer-Programme zu finden, die das Beobachten erleichtern. Ich habe auch ein DOS-Programm geschrieben (laeuft gut unter Windows 3.xx, Win98/Me): BJBEACON . Beachten Sie aber die vielen neuen Windows-Programme auf den Seiten der NCDXF.

Das High Frequency Active Auroral Research Program HAARP beobachtet auch die NCDXF-Baken.)
