[ih] Packet Radio Notes

[Jack Haverty]

There are archive sites which the normal search tools apparently don't 
reach.  But the documents they store are still accessible, but only if 
you use the search tool on the archive site.

I've found many old tech reports at discover.dtic.mil -- the Defense 
Technical Information Center.  Ignore the verbiage about logging in or 
setting up an account.  Just type your search term into the box at the 
top right of the page, labelled "Enhanced by Google".

If you can find them, the "contract number" associated with the project, 
or the "ADA number" identifying a specific document, are both good ways 
to do a search.   If Packet Radio Notes are anywhere, it's likely they 
are in DTIC.
