This is a complete rewrite of the SEM-25 page I published in December, 1998, with all-new pictures and a complete set of schematic diagrams. I plan to expand this further in the future, so check back here once in a while...
Note: You can click on each of the small images to get a larger image without legends, and then use your browser's "Back" button to return.
This page describes the German SEM-25 transceiver. I compiled this information to help other collectors who have (or are thinking of getting) a SEM-25, but cannot find technical information about it; manuals and schematics for this set are very rare in the U.S. at this time.
Please note that I do not have any original manuals for this set, and I do not even have a complete set of copied manuals (for example, I do not have any aligment procedures, and I would have great difficulty understanding them even if I had them due to my very poor command of the German language). I cannot provide any further information beyond what is described here at this time, and I cannot provide manual photocopies or other printed information at this time. This page truly contains everything I know about the SEM-25!
Please email me if you discover any errors in this paper.
I hope you find this information useful!
