RTL Dongle on Linrad5.0

[Earl Shaffer]

Hi All.

I have been using my RTL dongle on my windows 10 laptop on a previous version of Linrad which has been working fine for my purpose. The hard drive died so I installed Linrad 5.0 on my Ryzen 5 Windows 10 desktop computer.

The first thing I noticed is that there are now fewer gain options in setup but I tried both of them with similar results.

I can control the frequency of the dongle but when I try to change the gain in the same window the dongle complains in Linrads second window. I can change gain over a wide range and there is no change at all. If I close linrad and start it up again the new gain setting takes effect. This is the small window on linrad with frequency on top and gain on the bottom.

I used Zadig to install the Winusb driver as suggested in the RTL dongle video but there are now only two gain options instead of 4. The dongle seems to be a bit less sensitive now.

Hi Jim,

When you find differences in the rtlsdr setup it is because
you are using a different version of rtlsdr.dll

Have you executed setup-dll-05.exe ?

The dll files should reside in C:\linrad\dll and C:\linrad\dll\x64

Windows 10 may think it knows best and fetches rtlsdr.dll from
a system directory somewhere. Maybe a hidden way somehow. You
might delete the rtlsdr.dll files in C:\linrad\dll and if you do
not get a message saying this file is missing, Windows is using
some other version.
