Install all SDR programs and drivers in Administrator mode. Failure to do so
may result in incorrect installation of the frequency control drivers.
6 How do I install the drivers?
In the “CCW SDR4 general coverage SDR” folder is a program PE0FKOUSB
Driver_installer.
This program installs the driver and the Amateur Radio Root Certificate to
confirm the driver.
Inside the folder “CCW SDR4+ setup program v1.04” is a program that saves
the receiver drivers in a folder C:/SDR4+ on the target PC and places the
ExtIO_Si570.dll file in the HDSDR folder so that the HDSDR program can
control the frequency of the receiver.
Inside the folder is another program “Install_CFGSR_V2.6.msi”. Install this
program to ensure that drivers are correctly installed on Windows 8 and 10.
7 Where do I get the HDSDR program?
The latest version of the HDSDR program is included on the CD disc
“HDSDR_install.exe”. The latest version can be downloaded from the HDSDR
website:
http://www.hdsdr.de/
8 Is there a manual for the HDSDR program?
HDSDR is based on the earlier WinRad program. A guide to WinRad is
included on the disc,
“WinRad_UG_1.32.pdf
9 How do I get HDSDR to tune above 40 MHz?
When you have HDSDR running with the receiver select the ExtIO button to
the right of the Tune frequency display. This will open another program that is
used to control the receiver frequency.
Select the Si570 tab. This will open a page showing some details of the
Si570. At the top right is "Freq range". In the right hand window change the
default setting to 300.
Click the "Hide" button.
