    Rothammels is an awesome book and it is my go-to reference in understanding an antenna concept. From there I can jump to other primary sources. Of course us living in Wisconsin/Minnesota (10:20) are able to say Karl's name properly right off the bat.

    Working in a technical field with Germans for over 25 years I smile about this because he is spot on the technical aspects of exchanging the language is very difficult. He has done English speaking people a great service.

    His accent brings me back to my childhood growing up in New Ulm MN... MANY German language speakers... in high school it was the most taken language class and came in handy when walking downtown... the old ladies would switch to German to talk about you, I loved to turn around and go back at them in it! I have forgotten most of it... use it or lose it! New Ulm had a week long festival Heritagefest... aka Minnesota's biggest week long drunk LOL Schells Brewery in town so that was the beer we all drank because it was cheap direct from the brewery! If you get a chance to try it go for it but it can be an acquired taste...

    So a little bit about the background here, and the stuff that was mentioned around 09:00
    From what I could gather during the WWII amateur radio in Germany became progressively more politicized. After the end of the war, the remaining German territories were split into 4 occupation zones, and amateur radio was banned in 1945. Of those zones, the 3 western zones (French, US, and British) formed the Federal Republic of Germany, also called West Germany, and the Soviet zone became the German Democratic Republic, also called East Germany. During the reunification at the start of 1990s, the states forming the GDR split and joined the Federal Republic of Germany, leaving the West Germany as the only remaining Germany.
    If I remember correctly, in the western occupation zones, first amateur radio activity was allowed sometime in 1949, and the DARC, the German Amateur Radio Club, was formed in 1950. In the Soviet Zone, where Karl Rothammel was living, amateur radio was allowed later on.
    Also, about the book being popular in strange places... Well, one of the publishers was the publishing house of the National People's Army, the armed forces of East Germany, and through that cooperation, it made its way through publishing houses of other eastern block armies, translations were produced, and the Rothammel's book became THE antenna book in the eastern block.
    After the reunification, the publishing house of the German Amateur Radio Club continued publishing the book, and Alois Krischke, who was working with Rothammel, continued producing the new editions. He died recently, and the 13th edition was the last one which he made, and which was translated into English.

    The book was translated into Serbo-Croatian in 1983 and was (is) very popular in Yugoslavia. Strange that it didn't get a Slovenian version back then as well.

      If you think the League is a joke, explain how so. If you think its a joke, why are you not making an effort to change it?
      I often hear many complain about the ARRL, but rarely do I see any of the complainers doing anything to correct the issues they have. Instead they sit on the side, moaning and complaining, and overall sounding like a sad ham, and more like a whiny child.
      Over the years it appears that more and more hams are out for themselves and dont care about the collective gains for the hobby. The only goal is what they themselves get out of it, and if they arent happy they mostly bitch and moan about it, and they take their toys and go home. That's fine, I just wish they'd also keep quiet, or step up and help fix the issues.
      It is a great deal of what is dividing some in the service and hobby. The vitriol of this sucks or they suck or are a joke. Its rather insulting and old.
      I am a VE and have been at this for about 30 yrs, I am trying to get more young folks involved. When they hear comments that the ARRL is a joke, it sends a mixed message. Its like hating the government that also issued the amateur license you posses, and that issued your drivers license because you dont like the rules.
      Its confounding and confusing to me.
      The ARRL is by no means perfect. I too have some issues with them. however, I would in no way suggest they are a joke. Is there another radio club older? Larger? Better represented? Is there another radio association that has the ear of the US government in such a trusting and enduring manner?
      I would suggest that all of these strongly dispel the idea of the ARRL being a joke. Is the ARRL entertaining at times with some of their decisions? Absolutely. Does everyone feel represented all the time, no, however, everyone is represented somewhere along the way.
      I would strongly say the ARRL is by no means a joke but a serious Radio Association. I dont have to agree with everything it says and does, and trust I dont, I am very unhappy with some choices made, but I am still a member because there is no one else that will do a better job at representing my interests overall. As well, I can still file all the comments I desire with the FCC on my individual behalf, in support or disagreement with the league.

    ThxJosh - a copy (back) ordered on the basis of this good interview & "JOSH" $7 off.
    I was sad that you didn't discuss your "emergency J-pole" construction!
    I would have enjoyed some discussion of antenna modelling coverage in tbe book (use of which might have improved your "emergency J-pole's chances).
    Interesting that he's already queued-up at least one 2ed topic: "hex-beam" antennas, which have already had several generations of companies selling various versions.
