Old info about Windows drivers for various SDR hardware.

There is a lot to say about drive routines for soundcards under
Windows, but at the moment little of that will be exposed here.
Use Google, Yahoo or some other search engine.
Investigate your sound device,
look for inappropriate sound effects as the one described in
this MOON-NET posting
Upgraded computer, new issues.
Disable sound effects in Windows or select Portaudio with ASIO,
WDM-KS or WASAPI drivers in the Linrad setup.
Delta 44 drivers may be incorrect under Vista and Windows 7
The audiodg.exe bug(?)
may cause excessive CPU load.
The WSE units need a parallel port.
How to add a parallel port discusses some of the possible
solutions for adding a parallel port.
In case you want to use Linrad with SDR-14, SDR-IQ or
Perseus under Windows, first install the drivers supplied by
the manufacturer and make sure the units run with the manufacturers
With the Perseus such a strategy might fail.
perseus.exe might not work at all on a Pentium 3 and it might not work
under Windows 98.
To run Linrad with the Perseus HF receiver on obsolete platforms
(software and/or hardware,) download this file:
old-perseus.zip (63321 bytes)
It contains an old version of perseususb.dll as well as a directory
By installing the drive routine from "Drivers" and by placing the old
perseususb.dll in the path where you have your .sbs files it is possible
to run Linrad with the Perseus on Win 98 systems as well as on
elderly Pentium 3 systems where the winusb drivers do not work.

Each version of Linrad is compiled for a specific version
number on the sbs files for Perseus.
Go to this page if you want to use Perseus with Linrad and need
specific version of the sbs files:
sbs files for using Linrad with Perseus
For Perseus you might want to use this installer:
setup-linrad-perseus-bin-package-02.exe (2053168 bytes)
It will install perseususb.dll as well as the .sbs files in your
The binary files for Perseus will then automatically become
available for new Linrad versions.
For SDR-14 and SDR-IQ the file FTD2XX.DLL has to be available to Linrad
and the SDR-14 or SDR-IQ drive routine has to be installed.
In case if you do not want to install
you can download this file
ftd2xx.zip (266881 bytes),
unpack it to a suitable place and instruct the
Windows hardware installation tool to search for the drive
routines for "SDR-14" or "SDR-IQ" there.
Linrad can run with ExtIO plugins.
Extio is a "standard", designed by Alberto di Bene, I2PHD,
used for communicating with SDR hardware.
Such files are available for many hardware.
