The 2011 annual meeting (the 18th) of the Funkhistorischer Interessenkreis ("Radio-Historical Interest Group") took place in Dessau/Germany on April 29-30. I gave a 1+ hour presentation about the principles of Hellschreiber. My presentation (in German) can be downloaded here. This is a zipped file (146 MB !) that includes the actual presentation, as well as the associated audio files. All files must be unzipped to the same directory.

There were interesting presentations about the local activities of the (now defunct) military radio intelligence services of the former German Democratic Republic ("East Germany"), development in Germany of metal-ceramic radio tubes, a unique prototype of a very compact modular transceiver from ca. 1942, and two on the topic of Hellschreiber.
The meeting program also included exhibits of historic equipment (including several Hellschreiber models), visits to various sites and museums in the history-rich Dessau area (e.g., the Junkers museum), a ladies program, and general socializing. In all, very pleasant and interesting! The summary report of the meeting is here. A photo gallery of the various events can be found here (courtesy Paul, PE1BXL, and Marc, PE1RRT). |
I am - still - in the process of making an in-depth presentation of the Hell Feldfernschreiber and related topics. It will cover the same topics (history, what it is, how it works, circuitry, operation, software emulators, etc.) as found elsewhere on this website. It will include photos, video clips, audio. The video clips will be made after my Hellschreiber is put together again (currently undergoing "heavy" maintenance of the gearbox and drive train). Making a decent presentation is a time consuming process. The link to the current draft presentation is below. Note that this is still without video clips (though there are placeholder slides for that) and without voice narration. Dynamic slide transitions and intra-slide custom animation has not yet been optimized (need the narration first). Other than that, it is rather complete. If you download the zip-file, put all files in the same directory. It is in PowerPoint format (will be converted to FLASH later on, for streaming from this website), and should probably be viewed in "Slideshow" mode.

If you'd like to add a Hell scrolling banner to your website, or to a PowerPoint presentation: here is where I have explained how to do that.
On 12 November 2011, Dan Anghel (YO9ADN) gave a 20 minute presentation "FELD HELL, primul mod digital este inca actual" ["Feld-Hell, the first digital mode is still around"] and demo about Hellschreiber at the 2011 rally of the Amateur Radio Club in Bazau, Romania. Dan's PowerPoint presentation is, of course, in Romanian, and is based on my long presentation (see top of this page). .
