Getting it down to 1 meg would necessarily sacrifice almost all of the
detail in the photographs - they'd be unviewable. 1 meg might be
enough space for the text, and possibly for the black&white charts and
line drawings (as bitmaps) but the photos would be lost.

The reason it's 33 MB and not 1 MB is because the .pdf file is
basically a bunch of pictures, one of each page. That's also why it's
not searchable, and why you can't cut and paste text out of it.

33 MB is on the small side for books scanned like this.

In comparison, the Bible is only 1.34 MB in size in text format after
being compressed (http://www.gutenberg.org/etext/10) -- and it's a big
book. Even War and Peace is only 1.16 MB
(http://www.gutenberg.org/etext/2600).

In order to get it under 1 MB, you'd generally have to use some sort
of OCR software to convert the picture of text into text. I presume
there would also be some pictures, and they'd have to be stored as
pictures, of course.

Unfortunately, good OCR software is hard to find, and I know of no
software that could take a book, scan it, convert it to text and
images as appropriate, and do it accurately enough that a human
wouldn't need to proofread the entire document carefully. And that is
a very large job.

The reason it's available with BitTorrent is because that allows lots
of people to download it relatively quickly without totally sucking up
his bandwidth. It may be a bit more work to download than something
that's just a link on a web page, but it works nicely once set up.

In any event, scanning and distributing out of copyright books like
this is a worthy endeavor. Thank you!

Looks like there's a few other radio related works on Project
Gutenberg. Go to `http://www.gutenberg.org/catalog/world/search' and
search for `radio' for a list. None seem to cover antennas
specifically, but ` The Radio Amateur's Hand Book' looks interesting.

Doug McLaren,
To err is human, but to really foul things up requires a computer.

Fine Reader has no equal, still must be proof read, but I am always
surprised how accurate it is, when pages have been scanned at high enough
pixels... 200 is good, 300+ is excellent... it is smart and knows pictures
when it sees them... all this is easy to suck into word and put a book
together rather quickly... microsoft provides a FREE (what was Bill
thinking!) plugin for Microsoft Word which will construct a .lit ebook from
any word doc and presto... you have a ebook of excellent format--and even
with pics--small...

The guys on the #ebooks chan on the undernet servers of IRC used to provide
such books and info on how to create them--it is where I picked it up at...
they create books in all formats... but for quality and size, .lit is what
appeared best to me... microsoft provides a FREE (what was Bill
thinking?--again!) reader to read them, called "Microsoft Reader."

Warmest regards,
John

Hi Doug,

Also from Gutenberg (along with several dozen other titles) is my copy
of Casanova's Memoires (which fits in my Palm Tungsten E as an ebook).
It runs to 3.9 MB (about two feet of bookshelf space). No pictures by
the way.

73's
Richard Clark, KB7QHC

The pics would be converted to .jpeg... the text, in an efficient ebook
format, would be held compressed--very small... I did say one-meg+, I was
thinking about the pics (graphics) when I included the '+'... black and
white compresses very small, gray scale not as well... still, 33 megs is
HUGE! I don't see it being any larger then 3 megs at worst case... 1/10 is
good...

Warmest regards,
John
