1. Purpose of the program
The program TURBO535 Version 4 ( PD filename TURBO538.ZIP) has the aim
to control the SW receiver NRD-535(D) and to support the listening 
activities with: 

+ fast and easily to use and easily to update frequency data files 
+ extended and fast logging facilities
+ while searching  the ShortWave BroadCast bands the tuned frequency
  and actual time can be continiously compared with data in a added
  database, so you know to which station you are tuned (tracking)
+ SWL Workshop combining receiver control and access to frequency data 
  files and logging facilities 
+ flexible NRD memory management facilities 
+ analysis and processing of received signal strength to get insight in
  band use or propagation beheaviour
+ long term timer programming facilities to automatically record up to
  5 different broadcasts on a casette recorder while absent or asleep
+ direct receiver control 

Also some of the database functions can now be used with a NRD-525.

It is a MS Windows-application realised with Visual Basic v3, prof.

2. Installation
To install and set-up the program in the right way it is necessary to read 
chapter 1 of the documentation. Especial attention should be given the 
prescribed directory structure and the right place of all the files in this 
structure. 

In case TURBO538.ZIP is unpacked in an empty directory on your harddisk
called C:\TEMP and that directory is made the current directory, then,
after entering INSTALL the whole packet will completily automatically be
installed in a new directory C:\TURBO538, including all its sub-directories
and files.

Above all the programs available in the TURBO538.ZIP archive the Visual
Basic runtime module VBRUN300.DLL is needed. This file is not included 
because of its size.  It is available from the Simtel.Net as vbrun300.zip.  
It is also available from many on-line services and BBSs.

The documentation file is available in two versions :
DOC538GB.WRI : in the English language
DOC538NL.WRI : in the Dutch language
Both files are in the so-called .WRI format. The best results for reading or 
printing will be reached if the wordprocessor program WRITE, distributed in 
the Windows package, is used.

3. Stautus of the program and distribution
TURBO538.ZIP is freeware and freely distributable.
