[R-390] New Online 1970 US Navy R-390A manual

[Larry H]

Hi All,  I've reviewed the 1970 Navy tech ref for the R-390A that Nick has
so kindly scanned and recently put out on his website.  This is a high
quality scan.  You can view the manual at
https://www.navy-radio.com/manuals/r390a-063-2010-7004.pdf .  Nick said
some of the foldouts are longer than 34" so he had to break them into two
parts.  This is not a problem that I can tell.  All the pictures
and drawings are very readable and it has a parts list, too.

The benefits for viewing it *online* are: 1. the large and clear
schematics, and 2. it is *searchable*.  This makes finding a specific
subject very easy.
The reasons for *not* printing it are: it has a lot of pages wider than 8.5
x 11, and 2. It does *not* have an index.  It does have a very nice
improved contents, but specific items of interest are hard or not possible
to find in it because it is in the order of the material, and not in
alphabetical order (as an index is).

This is certainly a great file to use online, which I do a lot.
Thanks again, Nick.  I'm going to get a lot of use out of it.

If you really want to print an R-390A tech ref, I recommend the TM-11-856A
from 1/20/1956 on the r-390a.net website, 1st in the 'Army manuals' section
of the 'References' section.  It is overall the most correct and complete
tech ref, has an index, the best schematics for 8.5 x 11 printing, and
only very few pages slightly too wide for 8.5 x 11 pages.

He also extracted the wide fold out pages and put them into a separate
file.  They are here:
https://www.navy-radio.com/manuals/r390a-long-7004.pdf .  This makes it
easy to take them to a printer and have them printed on wide paper.  Or, if
you want a quick look at these nice schematics online, this makes it very
easy.  The actual schematic starts on page 8, part 2 is on page 11, part 3
on page 15, part 4 on page 14, part 5 on page 17, and part 6 on page 16.
 I just want to say again, *these schematics are fantastic.*

Thank you Nick!

Regards, Larry
