The preferred method of QSL is by Logbook of the World LotW of ARRL.  All QSO's are entered into the Logbook of the World (LotW) of ARRL.  But your card is welcome too.  Please send your request for QSL to DJ4KW. QSL-cards sent via the bureau must be marked via DJ4KW.  QSO's will be checked using the computer log and QSL-labels will be printed automatically.  Please no e-QSL.

All incoming QSL's will be answered.  QSL's received from the bureau will be answered using the QSL-service of the DARC (German Amateur Radio Club).  QSL's received by mail will be answered direct, if self-addressed envelope and sufficient return postage are supplied; German stamps, 1 IRC, or 2 US$.  If insufficient postage or no self-addressed envelope is supplied, your QSL will be answered via the bureau.   If you want to receive a QSL-card via the bureau, it is not necessary to send your QSL-card. 

You can send a QSL-request with your QSO-details by E-mail to: v31yn (ät)

August 2007 - Hurricane "Dean"  

Photo NOAA GOES-EAST of Tuesday August 21st 2007 at 08:45 UTC (02:45 local time)

Our location is on the lower edge of the red marked hurricane zone near the border between Mexico and Belize.  

Picture: Cumulative wind history of Tuesday August 21st 2007

We did not receive any news from Consejo till Thursday August 23rd morning.  There were reports from and, but the news teams did not come further than the district capital Corozal Town, about 10 miles South of our location.

At the location of V31YN many trees were unrooted and the roof of the restaurant was almost completely blown away, and there was damage to the other buildings, but nobody was hurt.  The 120 ft antenna mast withstood the 165 mph winds, V31AE had already hurricanes in mind when he designed it for us, well done Robert!  We lost all elevated radials.  

Cell phones worked again Wednesday Aug. 22nd 4 pm, but still no electricity, no water, no internet.  The Prime Minister of Belize declared the Corozal District a disaster area after extensive damage to homes and the mass destruction of crops.

Station V31YN, nur für digitale Betriebsarten Morsetelegrafie (CW, Aufnahme nach Gehör) und Funkfernschreiben (RTTY, PACTOR, BPSK31).  Sende-Empfänger ICOM 706, Netzteil PS85.  Es gibt kein Mikrofon und keine Moresetaste.  Sendungen für  Telegrafie und Fernschreiben werden nur durch den Rechner getastet.  Der Computer loggt alle Verbindungen, deshalb ist an der Station auch kein Logbuch zu sehen.  10 Meter Vertikal-Antenne gestattet interkontinentalen Betrieb auf Kurzwellenbändern zwischen 7 und 29 MHz (Wellenlänge 40 ... 10 m).   Die Lage am Wasser bietet optimale Ausbreitungsbedinungen Richtung USA/Kanada und Europa.  Das Glasfaserrohr für die Antenne ist mit 2 blauen Bändern befestigt.  Vom SGC 321 Antennen-Anpassgerät gehen Drähte, je 20 m, als Gegengewicht in über 2 m Höhe ab.

Station V31YN, digital modes only: Morse Code (CW, received by ear) and Radio Teletype (RTTY, PACTOR, BPSK31).  Transceiver ICOM 706, power supply PS85.  There is no microphone and no telegraph key.  Transmissions for the Morse code and teletype are only keyed by the computer.  The computer also logs all contacts, so there is no logbook to be seen on the station. 10 meters vertical antenna allows intercontinental operation on short wave bands between 7 and 29 MHz (40 ... 10 m wavelength).  The location at the sea offers optimum propagation conditions to the US/Canada and Europe. The glass fiber rod is fixed with two blue straps.  From the SGC 231 automatic antenna tuner there are wires with 66 feet as elevated radials, over 7 feet above ground.

Listen to two short sound recordings of radio telegraphy operation in Morse code

2001/2002: Zweiter Standort für Betrieb auf 160 m
(alternate location for 160 m operation)

Für Weitverkehr im 160 m-Band auf 1,8 MHz sollte die Antenne idealerweise mindestens 40 m hoch sein.   Robert Müller, V31AE, ermöglichte uns den Zugang zum benachbarten ehemaligen Mittelwellensender von Corozal.   Von der Spitze wurde eine Drahtantenne in das Sendehaus geführt.  Als Gegengewicht wurde das ursprüngliche Erdungssystem des Mittelwellensenders buchstäblich ausgegraben und neu angeschlossen.  

Im Januar und Februar 2001 wurden auf 1,8 MHz fast 500 Stationen aus Süd- und Mittel-Amerika, Kanada, verschiedenen Ländern in Europa, Hawaii und der Großteil aus 43 Bundesstaaten der USA erreicht.  Im Jahr 2005 brach der Mast zusammen, wegen mangelhafter Wartung - nicht durch Hurrikan. 

For long distance operation in the 160 m band on 1.8 MHz the antenna should be ideally at least 40 m high.  Robert Müller, V31AE, enabled us access to the former AM transmitter of Corozal Town nearby. From the mast top a wire antenna was led to the transmitter cabin.  As a counterpoise the former radial ground system of the AM transmitter was literally unearthed and reconnected. 

In January and February 2001 almost 500 stations were reached on 1.8 MHz from South and Central America, Canada, different European countries, Hawaii, and the majority from 43 states of the US.  In 2005 the mast collapsed, because of insufficient maintenance - not by a hurricane.
