For many years Hell-writing (which is a type of simple facsimile developed in 1927) has been considered to be no more than an oddity by the Amateur community, in fact most hams have never heard of Hellschreiber. It was however a simple mode, that offered very good performance in noisy conditions without requiring much power, if only you could find the equipment!

Now however, with Digital Signal Processing techniques and very good Windows software, the Amateur Radio fraternity is offered the opportunity to experience an advanced digital mode that requires no apologies for its performance.

Hellschreiber can outperform other modes for DX, and requires nothing more than a CW or SSB rig and a PC with a sound card. If you operate PSK31, you can also operate Hell, and what is more, make contacts that are not always possible with PSK31 due to poor conditions.

Operation is simple, slick, easy to tune, and ideal for QSOs and nets. Because of the unique nature of Hellschreiber, you actually see an actual replica of the transmitted signal, so the font used, bold or italic, is faithfully reproduced. Noise adds fuzziness to the received text, but cannot cause incorrect characters to print.
