1、TM-642 Service Manual PDF Some notes on this PDF are required as its 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.

2、 Ive 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. Ive printed all the 11x17

3、 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 tiffs scans can be downloaded at: http:/keekles.org

The entire document was OCRd in Acrobat, its not 100% but searching works most of the time. The only manual I can find is the 742 manual and its a bad s

5、can. The board diagrams are unreadable in it. Id love to get my hands on a 742 manual, but as these are out of print Ive 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

6、 to download it (looking at you mods.dk), or sell it on eBay or anywhere else. Ive done this as a service to the amateur radio community, and all should be able to benefit from the free exchange of information. Ive put over 10 hours into doing this right, and ask that you respect my wishes. Thank yo
