...to the homepage of Gottfried Ira OE1IRA...

These pages also address an international audience... you will find German language intermixed freely with another one, usually mistaken for English. Spelling corrections are welcome expressis verbis! Suggestions, tips, dead links, etc: please drop a note!

Hosted by Silver Server (no banners, no pop-up windows), located in Vienna, Austria (EU -- no kangaroos!!). Earlier incarnations were http://ira.club.atnet.at/ and http://club.atnet.at/ira/ (accompanying email address: ira@atnet.at). And yes, ira@iue.tuwien.ac.at was my address in a former life...

No gimmicks: pictures only where necessary, no animated GIFs, no Java, no frames, nothing proprietary like ActiveX or Javascript. If you can't live without, please go elsewhere. This project started as "bookmarks on the web", with new information being added as my scarce spare time permits. I may not be held responsible for the results of bad layout, boring design, rotten style or incorrect information presented here :-)
