Kenwood 742/942 Service manual

I hope this manual is of use to you.  Kenwood has not made this available as a PDF
and the existing scans are of such poor quality to be useless for any serious servicing
use.

Each  page  has  been  captured  at  600  dpi  at  the  proper  page  size.    OCR  was
performed on the resulting pages, while not perfect it makes for easy searching in
the manual.  I inserted the bookmarks and the additional service documents at the
end.

You should be able to print the large sheets on 11x17 or tile them on 8.5x11 paper
if needed.

Please do not charge for access to this manual, or put it on a pay walled website.
Erik this means keep it off your archive of plagiarized content known as mods.dk.

Please do not down sample/change the resolution of this manual if you re-host it.
I maintain the master copy on my wiki here:

http://wiki.w9cr.net/index.php/Kenwood_TM-742/642/942

I paid for the scanning of this which required the cutting of the binding of my service
manuals. I cannot say enough good things about the document processing
company who has done this scan. If you need a manual scanned I would be happy
to put you in touch with Stefan and his crew.

Thank you and 73,

Bryan Fields, W9CR
