QSL Update April 2016: I am very sorry but due to unforeseen personal circumstances the QSL printing has been delayed. I am still choosing the right photos (out of 8,500) and designing the QSL. Please be patient, all QSOs will be confirmed and all direct QSLs will be answered first (as soon as the QSLs are ready). I promise the QSL will be worth waiting for. Thank you for your understanding and your patience!
This was a special DXpedition celebrating my 40th birthday, my 10th wedding anniversary and my 25th anniversary on the air (a little late because it was already in 2013). For this reason I obtained the special callsign YJ4AO which is a reminiscence to my very first callsign Y24AO. A copy of my licence can be found here.
My wife and I always dreamed of visiting the South Pacific only once in our lifetime and we are very happy to be able to do this trip now.
Since I am a member of the National Geographic Society I would describe the technical term DXpedition as an abbreviation for Scientific expedition to a remote island in the South Pacific to explore the long distance radiation and reception of vertical polarized electromagnetic waves on high frequencies radiated by simple wires over salt water depending on solar influences like position, height or radiation.
Please come back later to this page as I might upload a few photos (or videos) while I am in Vanuatu or give some additional information about the DXpedition. Please scroll down for further information about myself or my previous DXpeditions.
Update: If you like to see the beautiful location of my QTH please check following drone videos:

Drone flight of antenna setup:
   1st fiberglass pole: Vertical dipoles for 20m-10m
   2nd fiberglass pole: Groundplanes for 30m/40m and feeding point for 80m Inverted L
   3rd aluminium pole attached to tree: Support for Inverted V for 160m
I have put up an Inverted L for 80m (attached to my 40+ radials) which runs into the next tree. With the help of Rod, YJ8RN, we have erected another 15m pole at a third tree which supports an Inverted V for 160m running along the beach. Unfortunately there has been a major solar eruption recently which makes it almost impossible to work on 160m/80m from this end of the world. Let's hope the conditions improve again soon. Furthermore I have got a lot of local QRM on 160m/80m/40m (up to S9+) sometimes which limits the reception of weak signals. I'll try my best.
Since I am using only limited equipment I am very interested to know how my signal sounds on your side of the pile-up. If you have the possibility to make a small digital audio recording of my signal (especially on the lowbands but also on the highbands) I appreciate it very much if you can send me a small compressed MP3 file to the following mail address: sunnyrob@gmx.de so I can listen to it when I return home.

For 80m & 160m I (usually) have no antenna that fits on my 10m fiberglass pole of DX-Wire. I feel that is not necessary for a simple lightweight holiday DXpedition that fits in my suitcase.
However I built a very experimental quick'n'dirty extension coil for my 40m groundplane just for the fun of it using an old Fanta bottle (Coke was out but the bottles are available anywhere in the world). Fine tuning can be done by filling water in it. Many people say this can't work on these bands with only 10m of simple wire on top of it but hey, they were all wrong. At least on 80m it works much better than I expected. More than 50 countries worked with 100 watts in the CQWW CW 2014 including several ZLs (ODX >13,500 km) is just enough to prove they were all wrong. Well, to be honest it is not that good on 160m. But for short distances it is ok and I even managed a contact with Europe from here... Check out the picture of the coil below. If you hear me calling on 80m or 160m please give me a call. I will appreciate that very much.

Worked extremely well on 80m but much worse on 160m, hi:

My name is Rob and I was born in 1976. Being first licensed at the age of 12 I started amateur radio as Y24AO from East Berlin on June 11, 1988. I was "infected" by my father (then Y25AO, now DL7VOB) but I learned this hobby also from Roy, DL7UBA, Bob, DJØXC, and Lar, DL3TD. While working from DJØXC's QTH I soon realized what my true challenge is: DX & Contesting, preferably in CW. So I decided to participate in major contests and to conduct my first DXpedition as HBØ/Y24AO in 1991. When I returned to Liechtenstein as HBØ/DL7VOA in 1993 I logged some 6,500 QSOs in about one week and realized how fascinating pile ups can be from the other end...

I had a little break in DXpeditioning but lately I have obtained an Elecraft K2 (100 watts) and re-designed my portable layout for minimum size and weight so it fits in regular flight luggage. Now I am enjoying low budget DXpeditions during the holidays with my wife Natalie. So please understand that most activities are conducted in "holiday style" during the local evening and night hours (mainly in CW) when my wife is asleep. My favourite bands are the lowbands so listen there, too.

In 1996 I decided to study Media Business Administration at the Technical University in Ilmenau and since then I am also operating in the major contests as DFØHQ respectively as DAØHQ during the IARU HF World Championships in mid-July.

I translated the DARC DX Newsletter from German into English language and distributed this DX bulletin worldwide via internet and packet radio from 1993 until 2013.

Until now I have worked more than 300 DXCC entities and have a few less confirmed. Since I am very busy with work and family I am now operating only during major contests or during my holidays. Please allow me a few weeks after returning from a DXpedition to design and print my QSL cards (due to my busy QRL).

Did you get to know what you wanted to know? Fine! If not, just send me an e-mail to dl7voa@darc.de and I try to answer as many questions as I can.

Have fun and don't forget: DX is!

73s de Rob, DL7VOA
