Since Radiomuseum.org was started in Switzerland, the majority of the existing articles are in German. But one can also find many excellent articles in English. And of course you can select your preferred language(s) in your profile so that only articles in those languages are visible to you.
Creating more English content is up to you, our English-speaking members. I’m happy to provide a venue for such articles – but it is up to you to write more articles!
First, some helpful links:
Suppliers for Vintage Electronics, Radio Parts, Tubes, etc.
Museum Finder - List of Technical Museums - Guide
Repairmen, Repairshops, Radio Repair - and Radiomuseum.org

RMorg Forum Rules
RMorg offers you a very different forum than you may be used to.
The only aim is to give solid answers to questions and to provide informative facts that will still be of interest years from now. Our forum is intended to be a data base, not a chat forum. There are many other forums where you can chat.
Our forum should be entirely factual and friendly.
We do not like guesswork or stating opinions instead of facts (which others might know better than you). Don't use ironic or sarcastic remarks - they can be misunderstood. Quarrelling or deleting/changing text after it is referred to by others can be a reason for termination of rights to the forum.
We do not discuss politics, religion or the rules of RMorg or this forum, nor other sites!
If you have suggestions or concerns, please write to an officer. You can find the list of officers by clicking "Administrators" on the home page (search page) and then "Staff" in the upper right. RMorg is not simply a club – we have a well defined organization with established procedures.
Examples of Good Forum Articles in English
Here I will try to show some examples of your work which your peers think are outstanding. If you send me nominations for additional articles to include here, I’ll be happy to expand the list and add more categories.
I think we should have more repair stories - either as general articles - or posted from the model page as model specific articles. The best articles have integrated pictures.
If you want to see more articles from one of the authors shown here, click on the “Articles of this author” link at the bottom of any article.
