[R-390] OT: Need manual for Racal

[2002tii]

I've tried almost everything I can think of, including calling the
manufacturer, but still no joy, so I thought I'd ask this august list for
help.

I have a "B" version of the Racal RA6790/GM (i.e., not the standard
R-2174(P)/URR version -- it is an R-2174B(P)/URR).  This version has LF and
VLF receive capabilities, and includes a number of modules that are not
documented in the manual I downloaded from BAMA (specifically, modules A14,
A15, A23, A24, and A25).  Some operational characteristics may be
different, including the BITE setup procedures and error messages.

Does anyone here have a "B" manual?

I recall downloading a couple of manuals from one or two US military sites,
but I have lost the URLs.  If anyone can refresh my recollection, I'll try
those for the R-2174B(P)/URR.

Thanks for any help,

Don Charles



ps.  When I tracked down the manufacturer, Racal Communications of
Rockville, MD, now Thales Communications in Clarksburg, MD, I was told that
all stock, parts, manuals, and design data were consigned to the dumpster
following the merger and relocation.  Progress.
