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.
|
||
|
|
|
||
|
|
By default, xfhell wants to install a directory structure in the $HOME of
|
||
|
|
the installing user. The SlackBuild overrides this, and copies that structure
|
||
|
|
into /usr/share/xfhell-$VERSION/.
