Har nogen erfaring med hell-schreiber?

For mig at læse er hell-schreiber kommunikation ligeså robust som morse kommunikation. Og hell-schreiber bruger ligeså lidt båndbredde.

Improvements that came as a result of software implementation:
* Depicting the received signal as shades of gray instead of monochrome, thereby making it much easier to read weak signals.
* Changing to a different font. Here is one mode that is truly international and independent of character sets: any thing that can be depicted as markings within a 7 pixels high grid, can be transmitted over the air.

Citat: "...
Note that this clever printer is stupid! It prints all sufficiently strong signals that it receives – be it the intended pixels, noise or interference. It has no notion of fonts, bits, pixels, encoding, speed, or synchronization. It does no decoding or interpretation, other than deciding "signal (not) present". Signal distortion may add unintended pixels, and may cause omission of intended pixels. This only makes the printed text harder to read. But unlike teleprinters, a Hell-printer can never print a wrong character! The human reader, with its impressive pattern-recognition capability, can read messages that are well "down in the noise":

can be used with a very simple CW transceiver. No other digi-mode can do this!
