My interest in the Feld-Hell mode started after I installed the MultiPSK software application.

First developed in 1929 by Rudolph Hell. Feld-Hell Island a Hellschreiber mode that uses On-Off Keying [OOK]. It Island a 'fuzzy' mode in that it does not use any coding. The mode Island not machine readable!
