Thanks for stopping by and welcome to "RADIO FRONTIER"- please also visit www.dl5rbw.de for more details. Have fun!

What does "RADIO FRONTIER" mean? Well - DL5RBW is located right on the borderline between Lower and Upper Bavaria both parts of the "Freestate of Bavaria" which furthermore consists of Upper Palatinate, Upper, Middle and Lower Frankonia and finally part of Swabia each having their own administration. As the borderline of the property is the borderline between Lower and Upper Bavaria and also the borderline between the county of Landshut and Erding its appropriate to call it "RADIO FRONTIER". You might ask yourself why Erding sounds familiar to you. Next time you are in your favourite grocery store with a good variety of beers have a look around. If you look for the answer you have to read on and find the answer somewhere in the text below......................

Running one of the BIG diesels of the Southern Pacific Railroad in Atlanta/GA - don´t ask for fuel consumption! A picture showing the whole locomotive is here:





Updating or changing the content of a site from time to time gives a better impression of the ongoing activities so I decided to add a selection of antenna pictures of one of the homebrew activities last year. You can see the perfect SWR/return loss curve (as predicted by the model) of the 28 MHz OWA Yagi (6 elements on a 11 m/36 ft boom) and a picture of the product at sunrise looking to northeast. Atop of it is a homebrew 50 MHz Yagi. Tower #2 is a 24 m/85 ft tiltover & crankup tower however its only extracted that much to make the 28 MHz Yagi sit at approx. 15 m.

Enough words have been said - now lets walk the talk!

Check out


to find out that this organisation forced the Japanese whalers to suspend their barbarian whaleslaughter many days sooner than planned. The Japanese whalers call it "harassment" - I would call it an appropriate action agains barbarism! Ramming and sinking ships if necessary to stop cruelty is absolutely fine with me. Keep on going SEASHEPHERD!

Being fascinated by riding/racing  motorcycles and at the same time being fascinated by wildlife, nature and environment does not have to be a contradiciton. See - my motorcycle is GREEN!

Read more about wildlife at the end of the bio!




for latest info about the DRM interference and in case you can hear the interference report it to the DARC monitoring system


Its important to collect as many cases as possible to find out what the coverage of this interference is and to increase the power of our argumentation. It is YOUR 20 m band as well so either fight for it or loose it!


A word of caution: I am CRAZY about everything with 2 wheels and an engine!

The latest addition (in 2005): "Green Monster". A 2005 KAWASAKI ZX-10R which is good enough that a few years ago a capable driver could have win races in the Superbike Worldchampionship. 170 kg@185 hp speak for itself! Probably the lightest and most compact 1000 cc series sportsbike that has ever been built - even the successors of it are heavier and bulkier again. In the summertime I am doing a lot of motorcycle trackday racing either at the famous Salzburgring near Salzburg/Austria which is very close or on another famous and traditional racetrack the "Sachsenring" in Saxonia near Chemnitz (former German Democratic Republic)

Always keep in mind - mastering a modern sportsbike is a real sport! Gone are the days when riders could allow to drink, smoke and hang around. Physical and mental demands are at a high level! Therefore always follow the rule:

Be as fit as your bike!

Just rolling around is a different story - this can be done with a beerbelly!

By the way - the name GREEN MONSTER stems from the jet powered vehicle which Art Arfons set his land speed world records with back in 1964 - the year I was born!





Other pictures


The Harley Davidson Softail (FXSTI) is used for relaxed cruising on Bavarian backroads to visit the next cafe or beergarden. However always keep in mind - drinking and riding is very dangerous! Can you imagine that this machine is almost twice as heavy as "Green Monster" but only has 1/3rd of the power. Its quite a difference switching between the bikes.




The other picture you see is the view from my shack window to the South. In the distance one can see the Alps. The mountainchain is the "Karwendelgebirge" in Tyrolia (Austria) near Garmisch-Partenkirchen. The rising slope above the trees on the right is part of the "Zugspitze", Germany´s highest mountain with an elevation of 2962 m (approx. 9700 ft) which also is the home of the Zugspitze 2m/70cm repeater.




Finally a view from the window of my hotelroom across Gallipoli (Province Puglia) located at the very southeastern tip of Italy where I went for a business trip in summer 2008. The sea in the background is the Ionian Sea. Of all my business trips this one was really nice driving on state road 16 (Adriatica) along the Adriatic coastline from Bari to Gallipoli and working 20 m with my mobile setup (Elecraft K2/100 and homebrew 20/17/15/12/10 mobile antenna) enjoying the "propagation advantage" of South Italy


Answer to the question above: look for bottles labeled "Erdinger Weissbier". Yes it´s the largest wheatbeerbrewery in the world!


Some words about DXing...........

As can be read in many good sources and is demonstrated by top level DXpeditioners every time my opinion as well is that working by numbers, working by letters in the prefix/suffix or the worst example working by countries seems to be an ever existing bad habit among DX stations. It probably has its origin in the United States where in the past it was possible to separate this huge country in East, Midwest and West with very different propagation in one country. However nowadays even in the US it makes no sense anymore as callsigns with every number are spread all over the US. For Europe it NEVER made sense because the countries are small and only few countries use different numbers for different regions. After all I NEVER considered it a smart way to work or control a pile-up but rather let propagation do the work for me. Its no good idea to force people with propagation to be quiet because of the "wrong" number in the call and pull out the ones that have no propagation but the "right" number. Openings can be short and being forced to wait even a couple of minutes only could mean the chance is missed. Keep that in mind! Of course it makes sense to sometimes call for the most difficult regions explicitely to check propagation as it is clear that signals for instance from Europe very rarely can compete with signals from Fareast or the Westcoast Northamerica in the Pacific for example. Getting the best out of working with propagation only however needs that the operator is skilled and exactly knows propagation which in other words means there is NO and I say NO valid excuse for working by numbers, letters or countries - its simply an apparent means of compensation for an operator that has not reached the top level yet.

I worked huge pile-ups myself WITHOUT the help of numbers and alike so I know what I am talking about. Therefore implying that these are only theoretical thoughts doesn´t work.

Some words about sealife and wildlife in general..................

Although riding a Japanese motorcycle (purchased before I came up with thatdecision for me) I not only dislike but HATE people hunting and killing whales, dolphins and sharks or buy their meat or fins! Justifying or supporting it is just as bad. Therefore whenever possible I try to not buy Japanese products and would never spend my holiday in countries supporting and practicing this kind of unnecessary slaughter. Countries doing that up to now are Iceland, Norway, Faroe Islands and Japan. The same is true for wildlife species that are threatened by extinction. However ANY cruelty against ANY creature is something that has to be banned! Maybe someone feels hurt by these words but believe me that "pain" is nothing compared to the REAL pain the mistreated creatures feel! Nowadays its not a matter of culture anymore - its simply sick!

Animals can´t shoot back - your DX competitors can! Be a REAL MAN and lets hunt DX - not animals!
