2025年2月19日 · Hellschreiber, or Hell, is a method of sending and receiving text using facsimile technology. It is unique in that the characters are not decoded, but "painted" or printed on a screen. There are...

Hell'o and thanks for your interest in the European Feld Hell Net! Why another Feld Hell Net? This net is here to give hams operating out of Europe more opportunities to make QSO's in Hell Schreiber modes. I am aware that other Hell nets exist, but they are often out of range (crossing the Atlantic is not easy), on bands that are not permitted ...

2025年2月19日 · Hell Club membership has surpassed 7600 Amateurs and SWL'ers around the world. In 2024 we have been averaging almost 40 new members each month. Not bad for an old mode! New Member Request...

For the latest status and operating frequency of these nets, check the "Nets" page of the Feld Hell Club. Currently (mid-2024), there is no more FH Net on 10 m (due to the sunspot cycle) and 160 m (probably due to range/participants limitations).

2021年11月24日 · Hellschreiber (Also known as Feld Hell or just Hell) is a teleprinter system developed in the late 1920's by Rudolf Hell, a German inventor. Hell physically prints characters onto the screen, unlike other modern teletype modes which encode and decode signals.

2025年2月19日 · In general, here is where you'll find most Hell activity. As with any ham radio mode, these are suggested frequencies but not etched in stone, so please listen first before transmitting, as...

The Hellschreiber, Feldhellschreiber or Typenbildfeldfernschreiber (also Hell-Schreiber named after its inventor Rudolf Hell) is a facsimile-based teleprinter invented by Rudolf Hell. Compared to contemporary teleprinters that were based on typewriter systems and were mechanically complex and expensive, the Hellschreiber was much simpler and ...

Today we use the term "Feld-Hell", or "Field Hell" for this system, to help differentiate it from the slightly different land-line press systems, and others of more recent invention. Each character of a Feld-Hell transmission is portrayed as a series of dots (picture elements or pixels), in a matrix, just like the printing of a dot-matrix printer.

FM Hell is a Hellschreiber mode. The Hellschreiber modes FELD HELL, PSK HELL , FM HELL and HELL 80 are graphical modes where characters are drawn and the interpretation done by the user. For FELD HELL, the transmission is done by On-Off keying (OOK) as in CW, by BPSK for PSK HELL and by AFSK in HELL 80 and FM HELL (MSK in fact).

The Siemens-Hell Feldfernschreiber (Feld-Hell for short) is a self-contained, portable teleprinter system that is based on the Hellschreiber system. The latter, in particular the printer part, was invented by Rudolf Hell in 1929.
