The sprint is this weekend and I don’t anticipate a whole lot of activity, but it should be fun to try.

Feld Hell

Feld Hell is an digital mode named for the inventor Rudolph Hell.

What is Hellschreiber?

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 several modes of Hellschreiber, the most popular being a single-tone version call Feld-Hell, an on-off keyed system with 122.5 dots/second, or about a 35 WPM text rate. FH has a narrow bandwidth of about 75 Hz. Feld-Hell also has the advantage of having a low duty cycle meaning your transmitter will run much cooler with this mode.

How can I operate Hellschreiber?

As with any digital mode, you need a PC and an interface to your radio. You’ll also need software. Today there are a number of freeware programs that can have you up and running in Hell in a matter of minutes. Not freeware but a popular program is MixW. We are building a complete list of Hell applications on our software page. For questions you may have about software, or how to interface your PC with your rig, watch the video below, visit our Groups.io to post a question. – from the website.
