CR3L (M/2) wins CQWW RTTY 2009

CR3L hat den CQWW RTTY 2009 in der Klasse M2 mit neuem Weltrekord gewonnen. Das CR3L Team mit dem OPs DJ3NG, DJ6QT, DK4QT und DL1YFF sicherte sich den ersten Platz mit 9.147.201 Punkten vor P49X.

CQ Magazine wrote in its recent edition of May 2010:
The German powerhouse of DJ6QT, DK4QT, DJ3NG, and DL1YFF (RRDXA Chairman) drove CR3L to a decisive victory over Americans [...] at P49X. The antennas at CR3L were asembled and towers erected in the days just prior to the contest. Despite the solar low, they managed to get within 14% of the world record set by [...] HC8N at the solar peak in 2002.

DL5XX on air as 9G5MM

Update August 12th 2008

DL5XX has been in Ghana from July 11t2 until August 7th
2008 for a
service corps project. 9G5MM QSL frontside
During my free time I setup a station and activated 10 to 80m on CW. My callsign has just been issued 12 hours before my departure: 9G5MM.

QSL Policy:

if you want a direct QSL, send SASE to

DL5XX, Stefan Radtke,
Finkenweg 24,
D-53545 Linz,

All other QSLs will be send out via bureau through GlobalQSL. Printing process at GlobalQSL for all QSOs initiated September 30th 2008.
LoTW: all QSOs uploaded August 27th 2008.

Online log contains all QSOs made from 9G5MM.

Open logs now accepted by ARRL
Written by DL5XX   

Some good news from ARRL: in the ARRL Newsletter from July 25th they announced to drop rule 5 of section III of the DXCC rules. This means that open logs are are not any more subject to possible disqualification from the award program.

I think this is good news since internet logs have already become state of the art and best practice in radio sports. We will continue to provide our RRDXA online log to all members all will enhance the service in the future.

From my point of view there is just one thing to consider: if a log is opened with all QSOs details, QSL managers should stop correcting QSO data on request like "....I worked you at 09:21 on 21 CW but you got my callsign wrong..." since these kind of requests are obviously too easy with open logs. So please don't change logs unless you are 100% sure about the request. Most DXpeditions do online logs so it's easy for everybody to check whether you got in the log.

4 SQ-antennas by DF6QV
Written by DF1LON   
Nachdem bekannt wurde, dass Franz, DF6QV, die so erfolgreichen 4 SQ-Antennen von TS7N, 5A7A und VP6DX konzipiert und die Steuerung samt Phasenschiebern dafür selbst gebaut hat, wurde immer wieder der Wunsch geäußert, nähere Einzelheiten von diesen Antennen zu erfahren.
Daher hat sich Franz dankenswerterweise entschlossen, seinen Vortrag beim diesjährigen RRDXA Frühjahrstreffen über seine Erfahrungen mit dieser Antennenform allen Interessierten auf der RRDXA-Webseite zugänglich zu machen

After it became known that Franz, DF6QV, had designed the 4 SQ-antennas for TS7N, 5A7A and VP6DX and built the phasing- and control-boxes himself, a lot of hams wanted to learn more about this type of antenna that yielded such outstanding results on the low bands during these DX-peditions.
Therefore we owe Franz thanks that he has offered to publish his script about a lecture at this year's RRDXA spring meeting  on his experiences with this successful type of antenna on the RRDXA web page.

WPX-CW 2008 M/M LX7I
Written by DL5XX   
A few days before the WPX-CW contest, another RRDXA team found the way to Luxembourg to run the contest at LX7I. Thanks to Philippe, a lot of pre-work was done when we arrived at his station. Although we could only set up 4 stations, we decided to go for M/M to maxmize fun as well as our club score. During the contest, we kept 3-4 stations on air most of the time. 10 Meter was the big surprise especially on saturday with nice openings within EU and a few stations from Asia. This was another nice event not only due to the contest. We made new friends with which we did not operate before. This makes contesting a unique community. LX7I Antennas

For the CQWW CW Contest 2007 I went to Madeira to operate from CT9L. Walter, DJ6QT, allowed me to use his station and he gave me a list of possible operators for the contest. I thought that I will be part of a team but now I was the head of the CT9L CW team 2007.
