Ken - -the  windows openme  thing suggests when you have windows  solve  it 
 ovvers 2 overpriced things  and then WinDjView being  the  third one!

But  wait... I  had to  check... apparently there are   some  file  
converters that will whip it to a pdf. useful  especially  for  people that deal a 
lot and want the PDF   format.

 DJVU, or déjà vu,, is a web-centric format and software platform for  
distributing documents and images. Djvu technology was originally developed at  
AT&T Labs between 1996-2001. It is a set of compression technologies, a file 
 format, and a software platform for the delivery over the Web of digital  
documents, scanned documents, and high resolution images. DJVU content  
downloads, displays, and renders quickly, looks nicer on a screen, and consumes  
fewer resources than competing formats. The DjVu library is distributed as 
part  of the open source package DjVuLibre which has become the reference  
implementation for files in the DjVu format. DjVuLibre continues to be  
maintained and updated by the original developers of DjVu since 2002.The .djvu  
extension is a computer file format mostly designed to store scanned 
documents,  specifically those containing a combination of text, line drawings, 
photographs,  and indexed color images. DjVu uses technologies such as image 
layer separation  of text and background/images, progressive loading, lossy 
compression, and  arithmetic coding for bitonal (monochrome) images. This 
allows for high-quality,  readable images to be kept in a minimum of space, so 
that they can be made  available on the internet.DjVu has been toted as an 
alternative to PDF,  promising smaller files than PDF for most scanned 
documents. DjVu developers  report that color magazine pages compress to 40–70 kB, 
black and white technical  papers compress to 15–40 kB, and ancient 
manuscripts compress to around 100 kB;  most usable JPEG images typically require 500 
kB. Like PDF, DjVu can contain an  OCR text layer, making it simple to 
perform copy and paste and text search  operations. Free browser plug-ins and 
desktop viewers from a number of  developers are available from the djvu.org 
site. Looking for how to open

It is called the DejaVu format, which  was developed quite a while back 
here in the U.S. to 
provide much smaller,  but high-resolution file sizes for documents.

Unfortunately, the  designers got involved in something else, and 
essentially abandoned it,  
after many files on BAMA were uploaded in that format.

Two Russians  have apparently recently gotten the software and have updated 
it quite a bit,  
so it works very well now.

The program you need to view those files  with is WinDjview for Windows 
computers (there is 
a version for MACs and  for Linux) and it is free on the web from various 
places, all  legitimate.

When you  install it,some versions of the program ask  you to install 
Yandex and make 
Yandex your home page, but all you have to  do is tell it, "no".

Go  here:

http://windjview.sourceforge.net/

and download it from  there. SourceForge is a legitimate site. That page 
will also tell you 
some  more about DejaVu.

I have printed off my DjView RAK manual and can scan  it into a PDF for 
you, but since there 
are 96 pages, it will take me  several days to find enough time to do it.

Manuals for the RAK and RAL  appear on eBay at odd times.

No. It works the other way around: it works fine with the  RAK but not with 
the RAL, the 
reason being that the filtering of the  signal at the detectoris too good 
in the RAL, but there is 
plenty of RF  available at the detector from the RAK for that to work well.

as  well... why?  if  you pick off last  rf amp

Better filtering in the RAL.
