Amsat Phase-3D Rudak Schematics
This page provides access to Postscript images of the Phase-3D Rudak schematics
and prepared by WA7GXD and provided to N3EUA.
WARNING - All of these files can be viewed using Ghostscript and the
gv viewer under Debian GNU/Linux. They all have various problems
though, as Lyle and I have been learning how best to generate printable
Postscript files from the latest Orcad. Once Lyle is back in the country, we
will freshen these files, taking advantage of what we've learned. In the
meantime, CPU B and the DSP modems print essentially correctly, except that
you may lose some of the page borders on A sized paper. The hardware modems
are scaled A size, but rotated in a strange way so that you can't really get
them to come out right on an A sized printer. The SIMMs can be made to print,
but you get a scaled down image rotated to fit on an A size page, using only
part of the page as a result.
In other words, don't waste your time trying to make paper from these files.
If you really need a printed set, ask
to make you a set.
Rudak consists of a stack of 4 major boards. Two are CPU boards with V53
procesors, one holds the 9k6 hardwired modems and the high-speed modem, and
the last holds all the DSP modulators and demodulators. Additionally, there
are customized memory SIMM boards populated with 25ns static RAMs organized
to support the Rudak EDAC controller's needs.
This is Jim White's latest cut at a
for the system.
This is the primary CPU board, with most of the external connectoring.
This is the secondary CPU board, almost like the primary.
The 9k6 hardwired modems, and the 153k6 modem.
The sea of Analog Devices DSP chips...
Used on both CPU boards.
