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/. |
