GENERAL DESCRIPTION
ABOUT THIS MANUAL
It will be observed that this manual consists of a collection of separate publications, each one of which
describes its own module or section of the equipment. Parts lists, applicable alignment instructions, and
illustrations which generally consist of assembly diagrams and schematics are included in each of these
booklets, which are identified by a "PUB" number and revision.
These mini-publications represent our attempt to assure quality of our documentation and at the same
time maintain the material as current as possible. In the usual large manual or handbook, a change made
to a single module might require a sentence or even several paragraphs be added, with the result that all
text following the change will shift, consequently requiring renumbering of all pages and subsequent
reprinting. These operations create an undesirable delay between the release of the revision to the
equipment and the re-issue of its manual, despite our extensive use of computers. It is our hope that this
republication delay will be reduced because revisions are nearly always done on one module at a time,
and a few pages pertinent to one module are obviously simpler to revise and reprint than the many pages
of a handbook.
Each section or module of the equipment is described in its own booklet. For each booklet, the format
generally consists of a block diagram where applicable, then the relevant specifications, then the circuits
are described, then test/alignment procedures are defined, and then the parts list is presented. Finally, the
Figures (illustration drawings in 11" x 17" size) complete the booklet.
The Parts Lists in all booklets have been compiled by, and then extracted from, the LARCAN materials
management computer system, and are current as of the date of issue of the booklet.
We have attempted to present our circuit descriptions in such a way that they would be meaningful to the
competent technician whose main objective is to look after the equipment. We have therefore minimized
the inclusion of material usually found in engineering textbooks, professional papers, and doctoral theses,
because much of the information from such sources, although meaningful to the EE, can be too heavy and
overdone for the beleaguered technician who is desperately trying to put a transmitter back on the air.
3-ring binders are used for LARCAN manuals as a courtesy to our customers because a 3-ring binder
enables assembly drawings and/or equipment schematics to be temporarily extracted and used in a more
convenient place when necessary. (Before their joining LARCAN, several of our staff technical people
were previously broadcast station engineering technicians, whose custom was to temporarily tape their
schematics to the transmitter cabinet doors for convenient reference when working inside the equipment).
Drawings whose numbers begin with 30C, 31C, 40D, 41D, 50E, or 51E may have been reduced in size or
even split into several sheets to fit into the booklet's 11" x 17" format. Should any reduced drawings as
presented in our manuals be found difficult to read, full size engineering blueprints are available at no
charge by simply writing, calling or FAXing our Customer Service department and requesting the
referenced drawing and revision wanted.
