Well, not really.


 
While there is a wealth of additional information in whatCharles has posted, my article is completely different. The document in hiscollection is a photo copy of the original ARRL document.


 
This document was scanned from the original and thenreformatted and a new page layout was done in MS word.


 
Besides making a new document, I solved the *unobtainium*tuning coil part problem, edited the original schematic into an 8BIT TIFF imageand enlarged it to fit a whole 8.5 x 11 sheet of paper. Then I added additionalschematics that should improve performance. After that was finished I convertedit to a PDF for universal readability. 


 
A list member alerted me that I had screwed up by not paperprinting and proof reading the finished document. (All the technical stuff wasOK.) I went back and found a whole bunch of little punctuation things andremoved some repeated sentences and did a general cleanup.


 
So I have renamed the corrected document AM Sync DetectorRev A. Just ask for *revised sync* if you wish a cleaned up copy.


 
But thanks to Charles’ comments, I will also add it to the www.ko4bb.comsite
