wsjtx on Debian and superfox mode
=================================

wsjtx 2.7.0~rc5 introduced a "superfox" mode where the DX station (the
superfox) uses a new 1.5 kHz-wide waveform to work up to 9 stations in
parallel, including a digital signature to prove the station is not a pirate.
(The "super hounds" still use normal FT8 signals that can be decoded normally.)

Unfortunately, the superfox code for sending and signing, and on the hound side
receiving and signature verification, is not open source, but released as
closed-source binaries sftx and sfrx. These binaries are not part of this
Debian package.

The wsjtx Debian package still supports superfox operation, but the sftx and
sfrx binaries have to be obtained separately and installed into /usr/bin/.

 * Download the wsjtx tarball from https://sourceforge.net/projects/wsjt/files/
 * Unpack the tarball
 * Unpack the nested tarball found in wsjtx-*/src/wsjtx.tgz
 * Go to wsjtx/lib/superfox/
 * Pick your architecture (amd64 = "linux", arm64 = "arm", arm32)
 * Copy foxchk sftx sfrx to /usr/bin

Other operating modes supported by wsjtx are unaffected.
