642 Service Manual PDF
Some notes on this PDF are required as it’s not possible to represent the printed
manual 100%.
•
The text only pages (up to page 30) are scanned gray scale at 300 dpi. I did
not retouch them in Photoshop.
•
31-‐34, 35-‐38, 39-‐42 and 43-‐46 are 11x31 inches in the original document.
I’ve split these into 11x17 inch pages.
•
The remaining pages are 11x15.5 in the original and are 11x17 in this
document.
•
The image pages were scanned at 1200 dpi and straightened in Photoshop by
hand then assembled into the pages. These were exported at 400 dpi into
Acrobat.
•
I’ve printed all the 11x17 images out on my 11x17 printer and checked them
against the original manual. Only the block diagram has visible distortion
where the images do not line up. This is minor IHMO.
•
The original Photoshop files are available online and even the original tiff’s
scans can be downloaded at:
http://keekles.org/~kb9mci/tm742-‐service-‐manual/raw/tm742raw.tar.bz2
(I’m aware it says 742, but it indeed the 642. It’s 8.1gb and I did not feel like
re-‐uploading it.)
•
The entire document was OCR’d in Acrobat, it’s not 100% but searching
works most of the time.
The only manual I can find is the 742 manual and it’s a bad scan. The board
diagrams are unreadable in it. I’d love to get my hands on a 742 manual, but as
these are out of print I’ve been unable to locate one. If you have one that I could
borrow or buy please contact me.
I do ask that you do not host this file on a site that requires registration or
membership to download it (looking at you mods.dk), or sell it on eBay or anywhere
else. I’ve done this as a service to the amateur radio community, and all should be
able to benefit from the free exchange of information. I’ve put over 10 hours into
doing this right, and ask that you respect my wishes.
Thank you,
Bryan Fields, KB9MCI
