28 + 29 May 2016 - CQWPX CW contest in "Holiday Style" from the Belgium Ardennes (460m ASL) signing ON/DJ5MO. Operating in between family activity using inverted L with automatic coupler, 100W output power. CU in the contest! QSL via HC.



I was first licensed in The Netherlands back in 1996 at the age of 17. Callsigns I held were  PE1RQT, PA3HHA, PA5RA and finally PA5R that I still own. In 2009 I moved to Germany and now live in Niedersachsen, DOK I43. Not until 2012 I applied for my German callsign DJ5MO.

I've always been interested in DX hunting and DXCC. In the year 2001 I went on my first expedition to Luxembourg with 6 other radio friends. In the following 10 years we undertook several expeditions to LX, GU and OJ0, in total making well over 100,000 QSOs. In the picture at the top right you can see me on Market Reef in front of the lighthouse that was our shack, and a special place on the earth for DXCC.

Next to this, i was active in the contestgroup PA6Z, starting out as a small group of enthousiasts, and growing into being one of the major contest stations in the Multi Operator Multi Transmitter category in the Netherlands. Some pictures of our antennas and the station setup are below.

Sadly, we were forced to give up our contest location in 2010, and never found a good alternative site for such a large station. So this story ended for us.

As an alternative, I set out to start contesting from my new home in Germany. The station is still under construction, as are my operating skills as single operator / low power. I always need technical and personal challenge, and for me that brings operating with 2 transmitters or SO2R. This is a wonderfull way of increasing your rates while keeping you focussed, but it requires operating skill and a dedicated station setup that is not easy to accomplish. The station setup currently consists of:

  • ICOM7700 + Kenwood TS950SDX
  • Microham u2r SO2R controller
  • Acom1000 amplifier (not used during contests)
  • 15 element log periodic dipole array @21m for 10 - 40m
  • Inverted L with automatic coupler for 10 - 160m
  • 2 element triband Yagi fixed east @12m for 10/15/20m
  • 4O3A high power bandpass filters
  • WX0B Sixpack 2x6 antenna switch
  • N1MM+ logging SW













Both radios are connected through the bandpass filters to any of the available antennas via a remote 2x6 antenna switch. This allows the operator to select the optimum antenna for the running station on one band, while picking new ones on another band using the second radio on one of the other antennas. Works pretty well during the slow times, but is a challenge during busy runs. The bandfilters provide the ability to listen on one band while transmitting on another band, without any interference. I've tried several options, the 4O3A filters are the best.

I have always preferred CW for contesting, but do work SSB as well. I hope to contact you in any contest, and I'm happy to QSL via buro, LOTW or direct.
