Hello and thanks for looking me up!


My log is uploaded to LoTW and CLUBLOG within a few days after activity. Never the less I'm collecting paper QSL cards via bureau or direct. Every incoming card is answered 100%.

I'm NOT an active user of eQSL.cc, but I upload my logs from time to time. In case of need, just drop me an email.

My main interests are making frinds around the world, chasing DX, contests (mostly /p) and building up and testing wire and Yagi antennas, and some other useful gear.

Please add your callsign to my web contact log by clicking the "Web" button above. Thanks.

impressions /p contesting in 2015, it's very recreative

If you got a minute, here's my story...

HAM since 1993, call DG9BIP in JO33VM. I started being qrv on Sat's (AO10, AO13, etc.) and doing some VHF/UHF DX (mostly during NAC). Due to license restrictions, I just could listen to HF transmissions using a Kenwood R600 fed by an inverted V. Some times later I was qrv in ATV too.

Equipment in 1998, left picture, bottom to top - right picture shows portable ATV operation (click on picture enlarges in new window)


  • Az/El Rotator Yaesu G-5600 controlled via Interface IF100 by InstantTrack running on a 386 computer, SSB PreAmp's 2m/70cm, Maspro 2m/70cm Oscar Hunter


  • 23cm home made dish with feeder, behind 23cm home made 20W PA in grey housing, 13cm home made feeder


In 2002 I went qrt because of job-related reasons and came back qrv in 2010 after moving to my actual qth, now on VHF/ UHF and HF (meanwhile respective license restrictions had been omitted). On 08-15-2012 I changed my callsign to DH9DX.

Due to the high level of man made noise at my qth (S6-8), at the beginning of 2011 I decided to get qrv outside the cities.

I built up the portable rig, packed it into my car and drove out for testing...

After assembling and raising the antenna I powered on the rig and....it beat my expectations - noise level only S1-2! That's it!

So, if you hear me /p on the bands, I'm somewhere in the countryside, enjoying ham radio, the nature and from time to time the sun...
