[amsat-bb] WISP replacement?

[Douglas Quagliana]

All,
   I'd like to get pbpg running with a soundcard modem on Linux. First, I'm
just trying to get pbpg running.

   I was able to download pbpg-2.2.1.tar.gz from the AMSAT website, and
after a little work I got it to compile and got it installed, but it
doesn't seem to run properly on my Linux box. I have kernel version 4.4.75
on this machine, but I could try another kernel version or a completely
different distro quite easily.

   I strongly suspect I'm "doing it wrong" and there's some more missing
setup and config (for example, the "configure/make/make install" didn't
create the control FIFO (/etc/pbpg/pb-fifo) nor any of the
/var/spool/pbpg/satellite-name directories.

   I think I'm missing a required step.  Is there more install/config
documentation somewhere besides what comes with pbpg-2.2.1.tar.gz ?
