- Terminal unit of "NF-Drahtfunk" early wired
broadcast system (1924-1939). Using regular telephone lines,
the "NF-Drahtfunk" allowed the terminal owner to
listen over a telephone line, to just one broadcast program
which would be interrupted every time when external phone
be continued after the picture set...
next generation of German wired broadcast system, the "HF-Drahtfunk"
approved in 1939, allowed to listen to 3 broadcast programs
over the telephone lines without any interruptions by the
incoming phone calls.
