The N7CFO Download Page

(Last update December 12, 2020)

Over the years I have accumulated a lot of reference material.  Much of it it is scarce, so I have decided to share it in Adobe Acrobat PDF format.

Most of these documents were scanned in grayscale, and as a result the files are huge.  This is the price you have to pay for good resolution on the photos and drawings.  The entire documents have been scanned unless otherwise noted.  I encourage downloads of these documents - this will ensure that they are preserved and will not be lost to future collectors. 

If you have documents to share, I would like to hear from you.  I would be pleased to scan or photograph them and make them available.
