-xfhell is a GTK+ application for the "fuzzy" digital communication mode 
-known as Hellschreiber. xfhell has several different built-in fonts in 
-Adobe BDF format, including a font set for Greek, and a special "short" 
-font set that is 12 pixels high instead of the standard 14 of the original 
-Hell fonts. Using this font set would make xfhell incompatible with other 
-Hellschreiber programs, but the short fonts speed up operation and avoid 
-wasted bandwidth, inherent in the original Hellschreiber design (an 
-unavoidable problem of the original mechanical implementation of the mode). 
-xfhell also has selectable lower baud rate operation (down to 7.6 Bd), 
-which again make it incompatible with other Hellschreiber programs, but 
-the lower speeds (especially combined with the 12-pixel fonts) would make 
-this mode even more efficient and effective.

-xfhell has built-in CAT control for the FT847 and FT857 transceivers and a 
-QSO logging facility similar to xpsk31. It also has a FFT-derived waterfall 
-display of the incoming signal, with the ability to detect maximum signal 
-level and tune the transceiver, via CAT, to the appropriate carrier 
-frequency by clicking near the signal trace.
