On YouTube sm5bsz has uploaded a video showing a comparison between the E4000, R820T and FC0013 tuners, and also comparing the receive performance of SDRSharp and Linrad. In the video Linrad showed superior receive performance with the E4000 when compared to SDRSharp due to some custom gain profiles which are enabled in Linrad only (but can also be enabled in SDRSharp with a plugin/mod).
Note that the reason Linrad showed better performance is purely due to the fact that he used a modified librtlsdr driver in Linrad which has the custom gain profiles. However, in a previous post we posted about a modification/plugin to SDRSharp which allows this modified librtlsdr to be used, which will allow SDRSharp to perform as well as Linrad for the E4000.
Linrad is another software defined radio program which is much more difficult to use, but was the first program to support the modified librtlsdr. Some people prefer Linrad due to it’s advanced GUI which has a lot of signal information on display.
